The instrument should be protected from temperature extremes which might cause
condensation within the instrument.
Original Packaging
It is recommended that the original factory packaging materials be retained for use when
shipping the instrument. If original packaging material cannot be retained, packaging
materials identical to those used in factory packaging are available through Hewlett-Packard
offices. Part numbers and descriptions of the packaging materials are listed in Figure 1.
The combined weight of the two instrument sections is approximately 50 kg (112 lbs).
Because of the weight involved, do not package the instrument sections fastened together as
one unit. The instrument sections must be separated and packaged in separate containers.
The quantity of packaging materials in Figure 1 is for only one instrument section.
If the instrument is being returned to Hewlett-Packard for servicing, attach a tag to each
carton indicating the type of service required, return address, model number, and full serial
number. For your convenience, a supply of tags is included at the end of this section. Also,
mark each container FRAGILE to assure careful handling. In any correspondence, refer to the
instrument by model number and full serial number.
Other Packaging
If it is necessary to use packaging materials other than the type used in original factory
packaging, the following general instructions should be followed.
IF-Display Section General Information 3
1. Separate the two instrument sections and wrap each in heavy paper or plastic.
2. Place the instrument sections in separate containers with 8 to 10 cm (3 to 4 inches) of
shock-absorbing material around all sides to provide firm cushioning and prevent movement
inside the container. Protect front panels with cardboard. Double-wall corrugated cartons
of 125 kg (275 lb) bursting strength are sufficient for shipping containers.
3. Seal each container securely and, if shipping to a Hewlett-Packard office or service center,
attach a tag to each container indicating the type of service required, return address, model
number, and full serial number. For your convenience, a supply of tags is included at the
end of this section.
4. Mark each container FRAGILE to assure careful handling.

Display Troubleshooting
The Display system consists of four sections:
Input Section A3A8 Analog-Digital Converter and A3A9 Track and Hold
Processor Section
A3A4
Memory, A3A5 Data Manipulator, A3A6 Main Control,
and
A3A7
Interface
CRT Driver Section
A3Al
Trigger, A3A2 Intensity Control, and
A3A3
Line
Generator.
CRT Amplifier Section
AlA
High Voltage Regulator and either
AlA
XYZ Driver
Amplifier (Serial Prefixes 3004A and above) or
AlA
Z Axis
Amplifier
AlA
X Deflection Amplifier and
AlA
Y Deflection
Amplifier
Isolation of a malfunction to one of the above sections is done with the use of rear-panel
display outputs and the internal test programs.
If the left INSTR CHECK LED is on, a failure has probably occurred in Digital Storage.
Refer to the A3 Digital Storage Troubleshooting notes for the correct troubleshooting
procedure.
The following paragraphs briefly describe the failure modes and appropriate places to begin
the troubleshooting.
Characters Only
If only the characters on the CRT display are affected, the problem most likely exists on the
A3A4
Memory.
Graticule and Characters Only
If the graticule and characters are incorrect, but the video information appears to be correct,
suspect the System ROMs on A3A6 first. Also the “long POP” test of the RF Section
memory should be performed. Refer to the Digital Storage Troubleshooting notes for more
information.
Al 1
Video (Signal) Only
If only the video information is incorrect, suspect A4 IF Section,
A3A8,
or A3A9. To
eliminate the IF, connect the rear-panel SWEEP and VIDEO RECORDER OUTPUTS to an
oscilloscope. If the video is correct, then either
A3A8
or A3A9 is defective.
Remove cable 96 from
A3A9Jl.
Then jumper
A3A8TPl
to
A3A9TP3
and push Instrument
Preset. This substitutes the sweep ramp for the video input. The CRT display is similar
to Figure 7 in the
A3A8
tab. If the ramp is incorrect, remove
A3A9,
jumper
A3A8TPl
to
A3A8TP6
and push Instrument Preset. The CRT display is the same as Figure 7 in the
A3A8 tab. If the display is correct, the problem is in the A3A9 assembly. Refer to
A3A9
Troubleshooting procedure. If ramp is incorrect, suspect ADC on A3A8. See the
A3A8
Troubleshooting notes to verify this.
Don’t rule out the sweep system, especially the ramp converter on
A3A8,
when
troubleshooting video failures. Some ramp converter failures produce CRT displays that are
similar to those caused by ADC failures.
All CRT Information Blank or Distorted
Check X, Y, and Z DISPLAY OUTPUTS on rear panel. If these are correct, the fault is most
likely with the X/Y Deflection Amplifiers or Z Axis Amplifier (or
AlA
XYZ Deflection
Amplifier). The following program, which places a dot at the center of the display, is helpful
when troubleshooting the Deflection Amplifiers. It balances the voltages in both halves of the
circuitry. Press Instrument Preset and key in the following:

End of display
If the X, Y, and Z DISPLAY OUTPUTS produce either distorted or no output, Digital
Storage must be tested. Connect a jumper from
A3A6TP3
to
A3A6TP6
and push
A3A7Sl.
The Digital Storage Test Pattern (Figure 1 of the A3 Digital Storage Troubleshooting tab)
results. Refer to the Digital Storage Troubleshooting procedures. If the test pattern is correct,
start with the system ROMs check.
If the test pattern is incorrect, verify operation of A3A3 Line Generator and A3A2 Intensity
Control. Refer to the troubleshooting information included with the schematics. If
A3A3
and
A3A2 are working properly, then all of Digital Storage will have to be checked, starting with
A3A6.
Whenever the display is blank, and the left INSTR CHECK LED is off, check the
AlA
f15
V Regulator (or
AlA
High Voltage Power Supply) and
AlA
+lOO
V,
t5.2
V
Regulator. The power supply
LEDs
indicate the presence of voltage but not regulation. Verify
operation of
A3A2
Intensity Control and
AlA
Z Axis Amplifier. If these are all working
properly, carefully examine the
AlA
High Voltage Regulator assembly.
If the CRT is blank, check the CRT oscillator to see if it is turned off. Measure
AlA6TP6
with a DVM. If TP6 is a digital high, the CRT will not operate since the oscillator is turned
off. Troubleshoot
AlA
to check for bad components, shorts, and so forth. If the
AlA
is

Keyboard, Circuit Description
AlAl
Keyboard consists of three functional blocks: CRT Controls, Keyboard Switches, and
Status Indicators.
CRT Controls (A)
The CRT Controls include the following front-panel potentiometers:
n
INTENSITY control
Rl.
Sets the level of the input to
AlA
2
Axis Amplifier.
n
ALIGN screwdriver adjustment
R8.
Sets the CRT trace to horizontal.
n
FOCUS screwdriver adjustment R2. Focuses the CRT trace.
n
FREQ ZERO screwdriver adjustment R3. For resolution bandwidths of 1
kHz
or less,
adjusts the frequency of the 18.4 MHz oscillator (A4A5 Step Gain) to precisely align the IF
passband
to 21.400 MHz.
The front-panel STANDBY indicator, LED DS16, which is driven by the PWR DWN signal
from
AlA
f15
V Regulator, is activated when line power is applied while the power supply
regulators are off.
Keyboard Switches (B)
The Keyboard Switches are a matrix of rows and columns connected to the RF Section
keyboard by the 50-wire Instrument Bus W8. When a keyboard switch is activated, Al5
Controller recognizes the switch and performs the indicated operation.
Status Indicators (C)
The 17 Status Indicators,
LEDs
DSl
through DS15, DS17, and DS18, show the states of the
various keyboard functions. Al5 Controller loads the latches
Ul
and U2 via the Instrument
Bus W8. The latch address is decoded in
A3Al
Trigger, which generates the ICLK strobe
signal.
Front-Panel LED Replacement
1. Set instrument LINE switch to STANDBY.
2. Loosen set screws in INTENSITY control and Video Trigger LEVEL control knobs
@

Z Axis Amplifier
/
AlA
XYZ
Driver Amplifier
The
AlA
board assembly has two versions that have major differences. The change of the
AlA
assembly is the result of a change of the
AlVl
Cathode Ray Tube (CRT).
The original
AlA
assembly (Instrument Serial Number Prefixes 2403A-3001A) is the Z Axis
Amplifier. It is used in conjunction with the
AlA
X Deflection Amplifier and the
AlA
Y
Deflection Amplifer.
The second version of the
AlA
assembly, the XYZ Driver Amplifier, replaces the original
AlA
Z Axis Amplifier. The XYZ Driver Amplifier (Serial Number Prefixes 3004A and
above) incorporates the circuitry of the
AlA
X Deflection Amplifier and the
AlA
Y
Deflection Amplifier, and replaces the
AlA
and the
AlA
assemblies too. The new
AlA
XYZ Driver Amplifier assembly, much larger than the original
AlA
assembly, uses the three
motherboard connectors used by the original
AlA2,
AlA
and
AlA
assemblies.

AlA
Z
Axis Amplifier, Circuit Description
(Serial Number Prefixes: 2403A-3001A)
AlA
Z Axis Amplifier receives from A3A2 Intensity Control two signals for control of the
CRT: a 0 V
-
2 V Z signal proportional to the CRT writing rate, and a blanking signal
LBLANK.
Amplifier
@
The Z signal, after attenuation by the front-panel INTENSITY potentiometer
AlRl,
drives
the input stage &g-&10. This amplifier supplies a differential current output to the Focus
Gate Amplifier and, through a Blanking Switch, to the Control Gate Amplifier.
Blanking Switch
@
Control Gate Amplifier
@
The input to the Control Gate amplifier is a virtual-ground, current-summing junction. Its
output voltage is given by:
Where
IQ7
is the current in Q7, which is determined by the Z-axis input when LBLANK is
high. When LBLANK is low, Q7 is off, and the output of the Control Gate amplifier drops to
a few volts, blanking the CRT.
Focus Gate Amplifier
@
The Focus Gate Amplifier supplies a correction voltage to the FOCUS grid of the CRT
to compensate for defocusing effects with varying intensity levels. The magnitude of this
correction voltage is set by FOCUS GAIN potentiometer R30 and the front-panel FOCUS
screwdriver adjustment
AlR2.
The output stage is identical to that of the Control Gate
Amplifier except for the pulse response adjustments (HF GAIN potentiometer R22 and HF
TRIM capacitor
Cl0
in the Control Gate Amplifier). These components are fixed in the Focus
Gate Amplifier.
CRT Adjustments
@
The CRT Adjustments set the bias voltage for the various CRT functions. Each adjustment
name is indicated on the schematic.

AlA
XYZ
Driver Amplifier
(85662-60232),
Circuit Description
(Serial Number Prefixes: 3004A and Above)
Y Deflection Amplifier
@I,
@,
@
The Y deflection amplifier consists of a single ended to differential voltage to current amplifier
@
which drives two current to voltage output stages. The result is a differential voltage
output to drive the positive and negative Y deflection plates of the CRT. The output has an
average (common mode) voltage of approximately 55 V (equal to the first accelerator voltage
of the CRT).
The voltage to current Y Preamplifier
I@
consists of a differential pair
Q113
and Q114 with a
constant current emitter bias supplied by Q115. R127 is used to adjust the collector bias to
position the beam in the center of the CRT when the input voltage is 1 V. This adjustment
also makes up for gun misalignment in the CRT.
Qlll
and
Qll2
are voltage gain stages and
Q109
and
QllO
are voltage to current converters
that drive a virtual ground input to the two current to voltage output stages with equal
but opposite signals. The gain of the
QlO9
and
QllO
stage is determined by the emitter
resistance. The differential gain is adjusted by R120 and
R119
and the common mode current
is set by R118 and R120.
The current to voltage stages,
@
and
8,
are identical so only Y+ Current to Voltage
Amplifier
@I
is described. The Y+ amplifier consists of an active load (constant current
source) made up of
QlOl,
RlOl,
R102 and R104 and a pull down transistor Q102. R102
and R104 set the base voltage of
QlOl
to a nominal dc level.
RlOl,
in the emitter of
QlOl,
sets the current in the collector. Q102 is biased on by R102 and R104 and is held in linear
operation by the emitter of Q104. R106 is the gain setting feedback resistor that maintains
closed loop operation. R108 biases the current to voltage amplifier input to set the minimum
output voltage to about 5.7 V with no collector current from
QlO9.
Kut
=
g
15 v
(
>
In general, the output voltage of the current to voltage stage is determined by the current
drawn from the input by
Q109.
This current is supplied by the feedback resistor R106. R106
is a 23.7 k resistor so the output voltage will rise 23.7 V for each milliamp of current drawn
from the input node.
Q103 is a feed forward circuit to help speed up transient response. A rise or fall in input
signal voltage will pass through the emitter follower formed by Q103 and R105 and then are
ac coupled through
Cl02
and
Cl03
to the base of Q102.
Cl02
also couples this voltage to the
base of
QlOl.
With the emitter bypassed against rapid voltage changes by
ClOl,
the active
load current is also modulated to help the ac response of the output stage.
CR102, CR103, R140 and spark gap
El01

Buffer Amplifiers
@)
There are two buffer amplifiers that are used to supply buffered copies of the Y signal to other
uses. One, UlOlB, is used to drive the rear panel Aux Y output. The other copy of the Y
signal is buffered by
UlOlA
and is used in the dynamic focus correction for beam position (see
FOCUS below).

Intensity Control

@
The intensity section takes brightness information from the line generator section (A3) of the
machine and provides analog modulation of the CRT and digital blanking.
Brightness
@
provides a high impedance input buffer (U401B) for the 2 axis signal that
comes from the wiper of the front panel intensity control. The output of
U401B
is used by the
brightness amplifier (U401D) and by the Focus Intensity Compensation Amplifier
@J
U4OlC.
The pot R319 is used to set the analog gain of the intensity amplifier. This adjustment is used
to calibrate the brightness of the CRT using a known test pattern and a light meter. R316,
R318, and R319 set the gain of the amplifier, while R317 is used to set the output offset. This
offset is used to set the overall minimum analog output level of the Control Gate Amplifier
6.
This level corresponds to the dc level at the Control Gate Amplifier output that will be
translated to the CRT cutoff voltage by the
AlA
High Voltage Regulator board. R315 is
used to translate the voltage brightness signal from
U401D
into a current at the emitters of
Q305 and Q306 of the Blanking Switch
0.
CR303 is used to prevent the emitter voltage of
Q305 and Q306 from going positive during turn on and damaging the base emitter junctions.
The Blanking Switch
@
consists of a differential pair current switch, Q305 and Q306. The
base of Q305 is biased at
-1.9 V by R309 and R310. The base of Q306 is driven from a TTL
signal (BLANK, low = dark) that is translated down in voltage by
R311,
R312, and R314
such that the signal at the base will swing either side of the -1.9 volt level on the other side
of the differential pair. The result is that when BLANK is low, Q305 will be on, Q306 will be
off, and the brightness current signal from R315 will be drawn through the collector of Q305
from ground. No current will be drawn from the input of the current to voltage amplifier.
When BLANK is high, Q306 will be on and Q305 will be off.
C305
is used as a
speedup.
In
this case the brightness current signal from R315 will be drawn through the collector of Q306
from the virtual ground input of the current to voltage amplifier.
R329 is used to set a minimum current draw at the input of the current to voltage amplifier to
set the minimum output voltage level when the brightness signal is blanked.

AlA
Control Gate Amplifier
&J
The current to voltage amplifier output stage for the Z Axis amplifier is similar in concept
to the one used in the X and Y Current to Voltage Amplifiers. There are some significant
differences in the input stages however. The active load current source is formed by
Q301,
R301, R302, and R305. The emitter of Q303 is at a fixed dc level of three base-emitter
junction voltages above ground (approximately 1.8 V). R302 and R305 develop a fixed dc
voltage at the base of Q301 and thus establish a fixed dc current in the emitter resistor, R301.
The emitter current translates into a fixed dc collector current source acting as a
pullup
for
the output node. Q302 acts as a common emitter pull down for the output node. Q304 is an
emitter follower driver for Q302 giving a large open-loop current gain in the pull-down half of
the amplifier. R307 is the feedback resistor that determines the closed loop current to voltage
gain of the stage. Q303 provides the dc bias path for Q301, Q302, and Q304, and also acts
as an ac feed forward amplifier to improve the transient response of the amplifier both by
modulating the current source load, Q301, and the pull down stage, Q302.
C307
is used to provide a zero in the feedback path to compensate the high frequency
response of the amplifier. R308 and
C304
are also used to adjust the high frequency response.
These two adjustments are used to optimize the step response of the amplifier when the
blanking signal is switched on and off. The rising edge is adjusted for best rise time without
overshoot. Any overshoot shows up as intensity modulation at the beginning of a vector. The
falling edge is not as critical for overshoot because the beam is off. Both rise and fall times
are critical because if they are too slow, vectors will have tails as the beam moves during the
transition time or there will be gaps between vectors that are supposed to be continuous lines.
Typically this design yields rise and fall times of 40 ns in response to the blank signal. The
rise and fall times for the brightness signal are about 150 ns. This signal path includes the
op amp stages
UlOlB
and
UlOlD
which determine the response time. The brightness signal
has one microsecond to settle between each vector so this signal path is much faster than the
signal that it needs to carry.
Focus Controls
0,
@,
0,
@
The focus control section consists of a dc focus voltage that is established by the
AlA
board
and the Focus
Gate
signal that is generated by the
AlA
board. The focus gate signal is
composed of four separate input terms fed to a virtual ground summing node at the input of a
current to voltage amplifier. The output of this amplifier is coupled onto the dc focus voltage
generated on the
AlA
board and applied to the focus electrode of the CRT.
The four focus terms are the intensity correction, front panel
FOCUS
and correction for the
curvature of focus field, top/bottom and right/left. The Focus Gate Amplifier
@
is nearly
identical to the Control Gate Amplifier
@I
except the high frequency compensation of the
focus amplifier is not adjustable and CR404 and CR405 were added to bring the summing
node voltage down to 0 V so that the top/bottom and left/right adjustment attenuators could
be referenced to ground.
Focus must be corrected for beam intensity. The focus voltage needs to be made more
negative as the beam current increases. This is done by taking the intensity signal from
U401B
@
and feeding it to a variable gain stage formed by
U401C,
R409, R410, and
R411.
This amplifier has an adjustable gain of from zero to approximately three. With Z axis signals
of zero to two volts this gives a maximum of minus six volts output from
U4OlC.
R412 (511
R)
translates this voltage into approximately 12
mA
maximum. This would translate to
over 140 V correction at the Focus Gate output if the FOCUS COMP pot, R409 were set to
AlA
5
maximum. Typically it takes about -40 to
-50
V correction from minimum to maximum
brightness.
Focus also needs to be “fine tuned” from the front panel. The front panel control is a
25~
pot with the two ends tied to +15 V and -15 V with the wiper brought to the
AlA
Front
Panel Focus
0.
The front panel signal is fed to an amplifier formed by
U401A,
R413 and
R415. C412 compensates the amplifier for less than unity gain by creating a poll at 28 Hz.
C411
provides a passive filter on the input line. This was found to be necessary due to signal
pickup from the focus gate output signal by the PC trace between R413 and the input of
U401A
that caused instability. R416 translates the approximately f7.5 volt output of
U401A
into a current at the summing node of
53.5
mA
as the front panel focus knob is rotated from
one extreme to the other. This translates to a focus voltage range of
f40
V. Nominally the
instrument focus is set up such that the front panel knob is in the center of its rotation and
therefore is not producing any net current into the summing node.
The other two terms in the focus voltage correction signal are the top/bottom and the
right/left focus corrections. The CRT has significant curvature of the focus plane. As the
beam is deflected away from the center of the CRT, the focus voltage needed to give optimum
focus becomes more positive. Typically it requires 20 V at the right and left edges and 10
V at the top and bottom to give the best overall focus. Top
&
Bottom Focus
0~
and Right
&
Left Focus
(EJ
contain identical offset absolute-value circuits. Since these two circuits are
identical, only the Top
&
Bottom Focus
EJ
is described.
The concept of this circuit is to generate a voltage that is proportional to the distance from
the center of the screen. Ideally, a parabolic function is desired. A three part piecewise linear
approximation will be adequate as the actual focus voltage requirements are not extremely
critical. What this circuit actually produces is a truncated, inverted “vee” current at the
input of the focus amplifier.
R425 and R427 provide a reference voltage for the offset of the absolute value. Normally R427
is set to give a one volt reference. This is nominally the video voltage that represents center
screen (0 V = bottom, 2 V = top of screen) and will therefore give a symmetrical correction.
Some individual CRTs will not be exactly symmetrical and will require that the offset voltage
for the correction be moved to get the best compromise of top to bottom focus.
With an input, both
U402A
and
U402B
positive inputs will be at positive one volt. Both of
these amplifiers are in a closed loop condition, therefore, the negative inputs are also at plus
one volt. Given these conditions, R417 and R420 have no voltage across them and therefore
are not carrying any current. Since net current at the negative input node of
U402B
must be
zero the algebraic sum of the currents in R418 and R419 must be zero. R418 and R421 have
plus one volt at their extreme ends so any difference in the current in R418 and R421 must
be flowing in CR408. CR409 would have to carry an equal and opposite current from R419,
but CR408 and CR409 can’t both be on at the same time due to their polarity. There is no
current in R418, R419 and R421, the output of
U402B
will be at plus one volt plus or minus
one diode drop depending on whether the input is slightly below or above the reference, but
no current is flowing in either diode.
With no current flowing in R420 or R421 there is no current in R423. The output of
U402A
must be at
+l
V. R426 acts as an attenuator for the output of
U402A.
The summing input of
the focus amplifier is nominally at 0 V so CR406 is reverse biased and there is no effect on the
focus amplifier output for our
+l
V (center screen) input signal.
With a 0 V input signal, R417 and R420 now have -1 V across each of them. Therefore, each
of these 4
k0
resistors will be carrying -0.25 mA. R418 must be carrying the same current as
R417 (CR409 prevents current from flowing into the
U402B
negative node) so R418 must have
one volt across it and therefore the cathode of CR408 must be at plus two volts. R421 has
plus one volt across it and therefore is conducting 0.5 mA into the negative node of
U402A.
R420 is drawing 0.25
mA
from this same node so the difference, 0.25 mA, must be flowing out
of this node through R423. The output of
U402A
is at -4.4 V. Current is drawn from the
amplifier summing node through CR406 from approximately -0.6 V at the cathode of
CR406.
This puts 3.8 V across R424 (maximum with R426 in a full clockwise position, zero with R426
in a full counter clockwise position). This current is summed into the focus amplifier input
and produces the correction for beam position.
The right/left focus correction is identical to the top/bottom. Both circuits sum into the
Focus Gate Amplifier input. The result is an asymmetrical, upside-down, truncated pyramid
approximation to an asymmetrical parabolic bowl. By adjusting the heights and offsets of the
pyramid for the best fit to the bowl one can achieve a focus uniformity over the whole CRT
screen.

High Voltage Regulator (85662-60059), Circuit Description
(Serial Number Prefixes: 2403A-3001A)
Warning
6
The CRT filament potential is connected to the -4000 V dc cathode potential,
which is dangerous to life.
The post-accelerator potential of approximately
+18
kV is supplied by High Voltage
Multiplier
AlAll.
Refer to block diagram.
High-Voltage Transformer
@
High-Voltage Rectifier and
Filter
@
The cathode of CRT
AlVl
operates at -4000 V dc. This voltage is generated by rectifying
an ac signal (approximately 30
kHz)
on the secondary of High-Voltage Transformer
Tl.
The
primary side of
Tl
is an oscillator circuit located in
AlA
f15
V Regulator. The rectifier
circuit consists of CR1 and filter components Cl, R3, and C3. The CRT filament voltage of
4.45 V rms is generated by another secondary winding of
Tl
and is held at -4000 V dc by
Rl.
The cathode voltage is stabilized by a feedback control circuit consisting of R4, C4, and the
amplifier circuit in
AlA
f15
V Regulator in conjunction with a primary feedback winding
on
Tl.
Refer to the circuit description of
AlA6.
The cathode voltage is set by HV ADJ
potentiometer
AlA6R32
in the Oscillator Level Control circuit of
AlA6.
Control Grid Level Shift
@
The control grid voltage is provided by generating a bias voltage with respect to the cathode
voltage. This bias voltage is generated by a capacitively coupled, clipped sine-wave signal
at the junction of C2 and C5. The sine wave is derived from the
Tl
secondary through R2.
The upper clipping level is set by INTENSITY LIMIT adjustment
AlA2R35
in
AlA
2 Axis
Amplifier. The lower clipping level is set by the output of the Control Gate Amplifier in
AlA2.
The clipped sine-wave signal is coupled to the control grid circuit through C5, where
it is rectified by CR3 and CR4 to generate a dc bias voltage across R7. C6, RlO, and C7
constitute a filter to remove ripple from the bias voltage. C7 also allows fast pulse signals to
be coupled directly to the control grid, to maintain response times of 30 ns or less.
AlA

Focus Grid Charge Level Shift
@
The focus voltage is set by a resistive divider string from the cathode, with an intensity-focus
correction bias developed in a manner similar to that of the control grid bias voltage described
above. FOCUS LIMIT potentiometer R14 sets the focus grid to approximately -2500 V dc,
and the focus bias is generated by a clipped sine wave at the junction of
C9
and
ClO.
This
upper clipping level is set by VR2 (+82.5 V),
FOCUS GATE voltage from
AlA2.

High Voltage Regulator (85662-60233), Circuit Description
(Serial Number Prefixes: 3004A and Above)
The High Voltage Regulator PC board couples the grid drive and focus control signals to their
dc bias voltages to drive the CRT. It also provides mounting and interconnect for the
AlASAl
High Voltage Module to
AlVl
CRT and the
AlA
High Voltage Power Supply drive and
control circuitry.
Control Grid Level Shift
@
The filament voltage from the
AlASAl
High Voltage Module is connected to the CRT
through this function block. The filament voltage is adjusted by adjusting the drive to the HV
module so as to get 6.0 V
20.05
V ac.
TPlA
and
TPlB
are provided to measure the filament
voltage.
Warning
High Voltage. Test points
TPlA
and TPlB are at -2400 V dc.
The cathode voltage is connected to one of the filament leads inside the
AlA3Al
HV Module.
Cl provides primary filtering of the cathode voltage while
Rl
and C3 provide a secondary
stage of filtering. The filtered voltage is fed to the CRT through current sensing resistor, R26.
The High Voltage Feedback is fed to the
AlA
High Voltage Power Supply regulator circuitry
through R3 and C2.
The control grid modulates the beam current and thus the brightness of the CRT. The grid
cutoff voltage of the CRT, the voltage that will turn the CRT off completely, is between -60
V and -90 V relative to the cathode. This dc offset on the grid is generated by capacitively
coupling an ac signal onto the dc bias voltage and rectifying it into dc signal. The amplitude
of the ac voltage is clamped to control the amount of dc signal that is added to the cathode
voltage. The source of the ac voltage is a winding in the High Voltage Module that generates
about 400 V p-p at 30
kHz.
One side of this winding is grounded at
J2-2
(COM). The other
side connects to
J2-3,
HOT. It is capacitively coupled through Cl3 and current limited by
R9.
The amplitude of this signal is clamped between two dc levels, Intensity Limit and Control
Gate.
Intensity Limit is an adjustable dc voltage (56 to 120 V dc) from
AlA
XYZ Driver Amplifier.
Control Gate is the output of the Z Axis (brightness) amplifier on
AlA2.
The Control Gate
signal is set to a dc level that represents the dark threshold level, the cutoff voltage. The
currents are small enough that the voltage drops across R12 and R13 can be ignored. CR4
is biased so that if the voltage at TP3 tries to drop below 45 V, CR4 will conduct and hold
the voltage at 45 V
(AlA
XYZ Driver Amplifier is designed so that the dark threshold is
approximately 45 V). The anode of CR4 is at a voltage between 56 V and 120 V.
VRl
adds
34.8 volts to the anode voltage of CR4 so that CR3 will conduct at somewhere between 90 V
and 155 V. This determines the upper value of the ac voltage and sets the adjustable range of
the peak-to-peak voltage of TP3 at between 45 V to 110 V. This ac voltage is coupled through
C4 to the node between CR1 and CR2. As the ac voltage swings negative, current flows
through R8 and CR2 to charge C5 to a negative voltage; as the ac voltage swings positive,
CR1 is turned on and the node is held at the cathode voltage. This results in a process
that charges C5 to a dc level more negative than the cathode voltage by the peak-to-peak
amplitude of the adjustable ac voltage. Since the cutoff requirement is between -60 V and
AlA
3
-90 V, the adjustment range is adequate to change a 45 V Control Gate dark threshold signal
into the desired cutoff voltage at the CRT grid.
To turn the CRT on, the grid voltage must be raised more positive toward the cathode from
the cutoff voltage. The Control Gate signal, the analog of the desired CRT brightness,
comes from the
AlA
XYZ Driver Amplifier board. The Control Gate signal has the correct
relative-voltage amplitude to drive the grid but it has a 0 V to 110 V signal range and the
grid is at -2400 V co (V cutoff). The 45 V dark threshold voltage can be translated to the
CRT cutoff voltage by adjusting the INTENSITY LIMIT pot on the
AlA
board. In order for
the beam to be turned on to the desired intensity, the grid voltage must be more positive.
The CRT has a maximum drive voltage requirement of 55 V. Drive voltage is defined as the
voltage, more positive than cutoff, that is required to bring the CRT to maximum allowable
intensity. The
AlA
Z Axis Driver Amplifier gain is adjustable, giving approximately 60
V above the 45 V dark threshold (105 V total). This signal is coupled onto the grid signal
two ways. If the instantaneous level of the control gate signal is raised, the peak-to-peak ac
voltage at TP3 is reduced by an equal amount. This raises the grid voltage by the same
amount that the ac voltage is reduced. The result is an Offset dc coupling of the Control Gate
signal onto the grid. However, the response time is fairly slow, requiring several cycles of the
30
kHz
ac signal to establish the dc level. This problem is solved by C6, which capacitively
couples the Control Gate signal directly onto the grid signal. The result of these two coupling
methods is that the fast edges are capacitively coupled and then the dc level is maintained
with the Offset dc coupling. This circuit accurately follows the 40 ns rise- and fall-times of the
Control Gate signal and also maintains dc level for the longest direct video vectors (10 ms).
Neon glow lamps,
DSl
and DS2, act to limit the grid-to-cathode voltage to approximately 150
V. This prevents arcing inside the CRT if a circuit failure should occur and on power-down
discharges of C5 and C6 as the cathode voltage drops. There are eleven spark gaps, El
through Ell, that are designed in as part the PC board traces. These spark gaps are used to
protect various low level signals against leakage or shorts in any of the capacitors that have
high voltage across them.
Focus Grid Level Shift
@
The focus grid in the CRT needs to be approximately -1500 V dc to properly focus the beam.
It is necessary to modify this voltage to correct for beam intensity and beam position.
The basic operation of the Focus Grid Level Shift is the same as Control Gate Level Shift
@
with a few exceptions. The Focus Gate signal works just like the Control Gate signal, it uses
the same ac and “Offset dc” coupling technique to couple the focus amplifier signal onto the
focus grid. The basic level of the focus grid id determined by a resistive divider formed by R2,
R14, and R15. R14 allows for the initial adjustment of the low brightness center screen focus
voltage. This is the voltage that all corrections are added to. Instead of the Intensity Limit
signal, the Focus Grid Level Shift circuit has a fixed dc level clamp voltage of 82 V set up by
VR2.
This function block also serves as an interconnect for the
+18
V dc and the DRIVE signal for
the High Voltage Module from the
AlA
High Voltage board.

X and Y Deflection Amplifiers, Circuit Description
(Serial Number Prefixes: 2403A-3001A)
AlA
X Deflection Amplifier and
AlA
Y Deflection Amplifier each consists of a differential
input state (QlO, Q15) with current source Qll, two current gain stages (Q9, Q14 and
QS,
Q13),
and two output differential current-to-voltage amplifiers. A display output amplifier
provides rear-panel X and Y DISPLAY OUTPUTS.
Current Amplifier (B)
The Current Amplifier transforms an input voltage change to a differential current change at
the collectors of
QlO
and Q15. This change is amplified in the following current gain stages
Q9
and Q14. POSN adjust R7 sets the CRT trace position, and GAIN adjust R27 sets the
CRT trace deflection limits.
The collectors of
QS
and
Q13
are virtual-ground, current-summing junctions of the output
amplifiers. When a signal is applied so as to increase the current in
QS
(decrease in Q13)
Q5 conducts more, turning off Q2 and causing the output (collector of Q2) to rise. Current
feedback through R29 supplies the increase in current required by
QS.
The analogous
operation, with inverted polarity, occurs in the other output amplifier.
Current to Voltage Amplifiers (C) (D)
Emitter followers Q7 and Q12 are feedforward amplifiers, coupling the drive signal directly to
the bases of
Ql
and Q4, thus improving the frequency response. Trimmer capacitors
Cl0
and
Cll,
along with HF GAIN potentiometer R28, adjust the amplifier frequency response for
minimum overshoot and equal risetimes
(~70
ns).
An input signal of 0 V to 2 V peak will cause a beam deflection equal to the length of the
graticule lines.
Display Output (A)
Display output amplifier
Ul
provides a 1 V maximum rear-panel signal to the X and Y
DISPLAY OUTPUTS.

Circuit Description
(Serial Number Prefixes:
2403A-3001A)
Warning
Unregulated voltages as high as +150 V are present in the IF-Display Section
whenever the power cord is connected to a power source. This condition is
annunciated by LED indicator
AlA8DSl.
Remove the power cord when setting
up service procedures.
The IF-Display section is activated by the logic signal HPON (power on), which is connected
to the RF Section via wire number 22 of the Instrument Bus. A logic “0”
(<+0.8
V)
holds the instrument in a standby condition with all unregulated supplies active and the
regulated supplies turned off. A logic “1”
(>+2.0
V) t
urns
on the regulators and activates the
instrument.
AlA
f15
V Regulator contains the
+15
V Regulator, to which all other supplies are
referenced, the -15 V Regulator, a thermal shutdown circuit, and active components
necessary for
AlA
High Voltage Regulator to activate the CRT.
Note
I
frf
Reference is made in the following paragraphs to components in other
assemblies:
AlA
High Voltage Regulator and
AlA
$100 V,
+5.2
V
Regulator. These components are identified by complete reference
designations; for example,
AlA6Q7.
+15
V Regulator (A)
Ql
and Q2 form a current source from the unregulated
(t23
V typical) supply. Under active
conditions, this current drives Darlington regulator
Q5
on until amplifier
Ul
senses an
equal-
voltage condition between voltage reference
VRl
(Ul
pin 3) and the sense input
(Ul
pin 2).
Ul
then holds that regulated condition by shunting the drive current through R4.
Foldback
current limiting is provided by Q4 and the voltage divider string on its base. This
circuit senses an overcurrent condition (higher voltage across
Rll,
R18) and limits the current
to a value proportional to the supply voltage.
Overvoltage crowbar circuit CR4 and associated circuitry shorts the output when an
overvoltage condition of approximately +18.5 V is reached. Zener diode CR3 conducts,
turning on CR4, which conducts and blows fuse
Fl.
AlA6/AlA7
1
The regulator circuit can be shut down by turning on Q3, which shunts the source current to
ground.
-15 V Regulator (B)
The -15 V Regulator is a tracking supply, holding the -15 V supply to the same magnitude
(inverted polarity) as the
+15
V supply, through divider resistors
R19
and R20. Overvoltage
and current limiting circuits are identical to those of the
+15
V supply.
Thermal Shutdown (C)
Thermistor R46 (negative temperature coefficient) is mounted to the heat sink of Q5 and
Q9.
As the heat sink temperature increases to approximately
8O”C,
the resistance decreases to
less than 107 R, and the voltage across the bridge circuit in which the thermistor is located
changes polarity, causing U4 to go high. This turns on transistors Q3 and
AlA7Q2,
to
shut down all power supplies, and transistor
AlAlQ2,
to light the front-panel STANDBY
indicator. Current feedback through CR6 holds the bridge circuit in an unbalanced condition
until the temperature drops to about
55°C
when the increased thermistor resistance again
switches the bridge polarity.
QlO
turns off the supplies by unbalancing the bridge when its
input (HPON) is less than about +2.0 V.
High-Voltage Oscillator (D)
The collector of
AlA6Q7
is connected to the primary winding of transformer
AlA3T1,
and
a feedback winding is connected to the base of Q7. Positive feedback from the feedback
winding causes the circuit to oscillate at a frequency (approximately 25 to 30
kHz)
determined
primarily by the inductance and capacitance of
Tl.
Q7 operates as a Class C amplifier,
supplying a large current (approximately 2 A peak) over a conduction period of less than
one-half cycle.
Oscillator Level Control (E)
Amplifier U3 regulates the dc level of the high-voltage CRT cathode voltage by controlling the
base drive to Q7 through the feedback winding. The cathode voltage is sampled via current
through
AlA3R4,
which is compared with a reference current through
AlA6R31,
R32, and
R50 (referenced to the
+lOO
V supply) at the input to U3. The output of U3 then holds the
base drive at the level necessary to maintain about
-4000 V dc at the cathode of
AlVl.
Amplifier open loop gain is set by R35, with R34, R36, and Cl4 limiting the control loop
bandwidth to approximately 7 Hz.
Cl5 supplies surge current for Q7, and L2 controls the conduction time of Q7. CR15 and
CR16 allow U3 to generate self-bias sufficient to maintain level control if the -15 V supply
should fail.
QS
disables the CRT by removing the $100 V reference for the regulator circuit.
Q8
is
controlled from
A4A9
IF Control, which may be addressed via the Instrument Bus.

High Voltage Power Supply (85662060232 and 85662-60250),
Circuit Description (Serial Number Prefixes: 3004A and Above)
+15
V Regulator
@$
The
+15
V Regulator is the same as the previous version of this board assembly
(85662-60101)
except that
+15
V dc voltage regulated by VR2 was
+lO
V dc in the previous
version. This voltage is always present whenever the 85662A is plugged in. It is used to
power the thermal shutdown section
0
and HPON (High=Power On) circuit. The main +15
V is turned off when in thermal shutdown or when HPON is false. Refer to
AlA

V
Regulator for additional information.
-15 V Regulator
@
The -15 V regulator is identical to the one used on the previous version of this board
assembly (85662-60101). Refer to
AlA
f15
V Regulator for additional information.
Thermal Shutdown
@
The thermal shutdown and HPON (High=Power On) control section is nearly identical to the
previous version of this board assembly (85662-60101). The difference is that R42 and R45
were changed from 6.19 KR to 11
KS2
to accommodate the change in power supply voltage
from
+lO
V to
+15
V. This change maintains the same voltage threshold for the HPON
signal. Comparator
U103A
is half of a dual comparator. Refer to
AlA
f15
V Regulator for
additional information.
High Voltage Power Supply
(6~
The High Voltage Power Supply provides the operating voltages for the CRT. These
voltages are: 6.0 V ac for the filament,
-2400 V dc for the cathode,
+9000
V dc for the post
accelerator and approximately 400 V p-p for the
AlA
High Voltage Regulator board to
provide dc restoration to the grid and focus signals.
The High Voltage supply is made up of
AlA3Al
High Voltage Module interconnected through
the
AlA
High Voltage Regulator and the
AlAlO
Display Motherboard to
AlA
High Voltage
Power Supply that contains the
+15
V and -15 V power regulators and the drive circuits for
the High Voltage Module. The High Voltage Module consists of a transformer that generates
the ac voltages and various rectifier and multiplier circuits to produce the dc voltages.
The transformer primary and
Cl06
form a resonant tank circuit at about 30
kHz.
Energy
is synchronously pumped into the tank circuit from the High Voltage Power Supply
Q
and
the cathode voltage is fed back from the
AlA
board through
AlA3R3
to form a regulated
feedback loop (HV FEEDBACK).
The power to run the high voltage supply is pre-regulated by
U104,
a three terminal regulator,
to
+18
V dc. This pre-regulation helps save some heat dissipation in the drive portion of the
HV supply.
U103
supplies the average power for the supply, while
Cl03
and
Cl04
supply
much of the pulse of current to pump the resonant tank.
U104
goes into current limit at
approximately one amp during the pump pulse (peak current about 3 amps) then recharges
the
Cl03
and
Cl04
before the next pulse.
AlA6/AlA7
3
LlOO,
R126, and
Cl00
form an input filter. The values of
LlOO
and
Cl00
ensure that the
current in
LlOO
is continuous; therefore, the 30
kHz
component is minimal in the load current
presented to the
+23
V unregulated supply. R126 is used to lower the Q of
LlOO
and Cl00 to
less than one. This ensures that there will be no ringing at their resonant frequency.
LlOO
is a
toroidal inductor to minimize radiated magnetic field.
The synchronous pumping circuit consists of
UlOO,
U103B,
UlOlA, and
QlOO
and associated
passive components.
UlOO
is a pulse width modulated switching regulator IC. It has a ramp
generator and several comparators that can terminate the output pulse that starts at the
beginning of the ramp.
R118
and
Cl17
determine the slope of the ramp.
U103B
is a comparator that observes the ac voltage of the tank circuit formed by
Cl06
and
the high voltage transformer primary. When the voltage passes through zero volts from high
to low, the output of
U103B
goes high. This signal is connected to the EXT SYNC input of
UlOO,
and causes the ramp to reset and start. Resistors
U102A
and
U102D
are not the value,
ensuring that the comparator will trigger a ramp at start up (when there is no ac signal in the
tank circuit).
The output pulse,
OUT COLLECTOR,
starts at the beginning of the ramp and is terminated
by one of several events. The output is an open collector that is pulled to
+15
V by
R121.
This signal is inverted and buffered by UlOlA. UlOlA is able to provide large peak currents to
drive the gate capacitance (approximately 1200
pF
maximum) of
QlOO.
R122 limits the peak
current at the gate and slows the switching time slightly. This protects UlOlA and helps to
reduce EMI.
When
QlOO
is turned on, current begins to flow in
LlOl.
LlOl
is a toroidal inductor to
minimize radiated magnetic field. This current builds up during the duration of the output
pulse from
UlOO.
When the output from
UlOO
is turned off,
QlOO
is turned off also. Then the
current in
LlOl
continues to flow, forward biasing CR103. The current begins to flow into
Cl22 and through R120 and back into
LlOl.
R120 dissipates most of the stored energy from
LlOl.
Cl22 slows the rise time of the voltage into R120 and helps reduce some radiated
EMI.
The turn off time of
QlOO
also slows the rise of the voltage into CR103, minimizing
EMI.
This shows the ability to sense the downward zero crossing of the sine wave voltage of the
tank circuit and pull it down in phase so that energy may be added to the tank.
UlOO
has
the ability to control the maximum possible output pulse length. This is done by
RllO
and
Rlll
and is set so that the pulse is always less than one quarter of the resonant period. This
is essential to prevent a gain reversal where longer pulses would begin to subtract energy from
the tank once the voltage began to go positive.
The current in
LlOl
is sensed by R124 and is fed back to the
CURRENT LIMITING
input of
UlOO.
If the average current rises too high, the output pulse will be cut off. This should only
happen in a fault situation and is used primarily for damage control. R124 also provides a
test point to observe the currents in
LlOl.
The cathode voltage output from the high voltage power module is sampled by
AlA3R3
and
is fed to this board as the
HV FEEDBACK
signal. The cathode voltage is approximately
-2400 V dc and
AlA3R3
is 30
Ma.
HV FEEDBACK comes into a pot R103 and then to
a resistor, R102 to +15 V dc. CR100 and CR102 protect the input of
U105A
in case of
arcing in the high voltage section
(AlA3)
that might cause any excessive voltage on the HV
FEEDBACK input. El is a spark gap that is designed in as part of the PC board traces. It
should break down at about 1500 V in dry air (less in humidity). Normally, there is only a
few volts at El and no leakage should occur.
4
Al
A6/Al
A7
When the loop is closed, the wiper of R103 will be at about
+8.4
V and is connected to the
negative input of U105A. The positive input of
U105A
is tied, through R123, to the
+8.4
V
reference voltage generated by
UlOO.
U105A
is an integrator below the frequency of the zero
formed by R105 and
Cl12
(112 Hz) and a gain of approximately three above that frequency.
U105B
is a dc gain stage of approximately four. R108 and
R109
provide offset to allow
the output of
U105B
to be near the middle of its power supply rails (0 and
+15
V) while
the signal meets the input range requirement of
UlOO
pin 5 (MODULATOR). This input
compares the ramp to the pin 5 voltage and when the ramp reaches the same voltage as pin 5
the output pulse is terminated.
This is a resistive divider to sample the cathode voltage and compare it to a dc reference.
The difference in these voltages drives an integrator, which controls the pulse width of the
drive signal. This drive signal injects energy into the primary tank circuit of the high voltage
module that generates the cathode voltage. This is a second order loop, which has infinite
gain at dc, and the average dc cathode voltage is well-regulated. There is some voltage drop
during portions of the CRT refresh cycle that are outside the bandwidth of the control loop,
but it is only a few volts and has no effect on the display performance. The individual vectors
drawn on the CRT draw beam current for either 4 ms or 19 ms depending on the length of
the vector. The filter capacitors on the
AlA
High Voltage Regulator board provide filtering
of the cathode supply for the high frequency components of the beam current, while the
regulator provides the low frequency average.
This circuit regulates the cathode voltage. The life of the CRT is dependent on filament
voltage. It is very important that the filament have the correct voltage and that is held within
a narrow range. If the voltage is either too high or too low, the life span of the CRT will be
shortened. The filament voltage comes from the same transformer as the high voltage, and
there is good correlation between the two for any given high voltage module.
UlOO
contains a
soft
start feature. The maximum length of the output drive pulse is
determined by the voltage at pin
6,
the
DUTY CYCLE
input. This voltage is derived from
the internal reference voltage from
UlOO
divided by
RllO
and
Rlll.
As
Cl16
charges on
power up, the drive pulse slowly increases in width and the high voltage ramps up slowly.
This prevents any large start up power surges. The start up power has a RC time constant of
about 400 ms and has a small (5-10 percent) overshoot as the integrator comes off the rail
and comes into regulation.
This power supply has a remote On/Off capability. This is activated by a TTL signal from
the A4A9 IF Control called CRT DSBL (low = HV on). As a safety feature,
R114
holds the
supply of in the absence of the IF Control assembly.
UlOlB
is used as an
invertor
to get the
correct polarity signal to operate
UlOO.
R116
and
R117
attenuate the signal form UlOlB to
an appropriate level for
UlOO.
In order to prevent an 20
kHz
noise from radiating to other circuits, a filter network isolates
the
+15
V dc that is used to power the control section of the HV power supply.
L102
and
Cl09
provide a low pass filter and R125 damps the Q of the filter to ensure there will not be
any self resonance. The control section of the high voltage power supply does not use the
-15 V power supply because if it were to fail, the
U105
outputs would rise and turn the high
voltage regulator on harder than desired, perhaps causing an over voltage condition on the
CRT. If the
+15
V supply fails, the drive circuit stops working and the high voltage supply
will shut down.

AlA
Rectifier, Circuit Description
Warning
Because of the high voltage present in this assembly, servicing should be
performed only by qualified personnel.
AlA
Rectifier contains three bridge rectifiers and one full-wave rectifier to provide
unregulated power for the IF-Display Section. External power is supplied to the instrument
through Line Module FL1 and Power Transformer
AlTl.
+9
V UNREG
Full-wave rectifier CR7 and CR8 provides an unregulated
+9
V to
AlA
+lOO
V,
+5.2
V
Regulator. LED
DSl
is lit whenever there is power to the transformer.
Test points
TPl
and TP2, when jumpered together, cause HPON to go high, turning on the
IF-Display Section in the absence of a signal from the RF Section when power is required for
troubleshooting.
The LINE TRIGGER voltage is selected as required by
A3Al
Trigger.

The
AlA
Rectifier board assembly has three versions; HP Part Numbers 85662-60133,
85662-60204, and 85662-60234. Each version changed this circuit.
85662-60133 (Serial Number Prefixes:
2403A-2813A)
Bridge rectifier,
Ul,
provides an unregulated +118 V to
AlA
+lOO
V,
+5.2
V Regulator.
85662-60204 (Serial Number Prefixes:
2816A-3001A)
This bridge rectifier is made of discreet diodes CR13, CR14, CR15, and CR16. This bridge
rectifier provides an unregulated +118 V to
AlA
+lOO
V,
+5.2
V Regulator.
85662-60234 (Serial Number Prefixes: 3004A and Above)
This bridge rectifier, made of discreet diodes CR13, CR14, CR15, and CR16, is stacked on the
+23 V Unregulated Rectifier output to provide an unregulated f140 V to
AlA
+lOO
V,
t5.2
V Regulator.
AlA8/AlA9

Warning
Q
The time constant of the filter capacitor is about 25 seconds. Before servicing,
allow adequate time for discharge after line power cable is removed.
+23
V UNREG
The
+23
V unregulated supply, bridge rectifier CR9 through CR12, includes an overvoltage
protection circuit. If line power from a 220 V/240 V source is applied when the Line Voltage
Selector is set to 100
V/120
V, the overvoltage causes CR6 to conduct, turning on CR5 to
blow the fuse in the Line Module.
+5 V UNREG
Bridge rectifier CR1 through CR4 provides unregulated +5 V and -15 V to
AlA
f15
V
Regulator.
AlA
Bus Transition, Circuit Description
AlA
Bus Transition provides jack
52
(inside front panel) for the
50-wire
Instrument Bus,
which is routed through the IF-Display Section through a flat ribbon cable W8.
HPON, the IF-Display Section power-on control line (W8 wire 22), is sensed by amplifier
Ql
and Q2 to activate fan relay
Kl,
which supplies line power to the cooling fan
Bl.
The i-5.2 V supply is connected to the LSTP line (W8 wire 43) through
CR1
to halt
operation of Al5 Controller if there is a supply failure.

A3 Digital Storage, Circuit Description
A3 Digital Storage consists of three sections:
Input Section A3A8 Analog-Digital Converter and A3A9 Track and Hold. This
section receives the video and sweep signals, converts them to digital,
and transfers the data to the Processor Section.
Processor Section
A3A4
Memory, A3A5 Data Manipulator, A3A6 Main Control, and
A3A7 Interface. This section handles all data transfers, data functions,
and control for the data storage. The digital storage algorithm is
contained in read-only memory (ROM) in A3A6 Main Control.
CRT Driver Section
A3Al
Trigger,
A3A2
Intensity Control, and A3A3 Line Generator.
This section, under control of the Processor Section, generates beam
control signals (X, Y, and
2)
to display the memory data.
A3 Digital Storage, Troubleshooting
The troubleshooting information in this section is organized in the following manner.

Digital Storage Failure Tests
1. INSTRUMENT CHECK LED
The left INSTR CHECK LED (CHECK LED I)
remaining on after Instrument Preset is
pushed indicates that a bad bit was detected when the analyzer performed its self check
routine. This check routine writes and reads to the read-write memory (RAM) in Digital
Storage. To activate this test, press Instrument Preset.
2. DIGITAL STORAGE TEST PATTERN
The test pattern shown in Figure
l-1
can be used to verify the existence of a failure. This
A3 1
pattern can be generated independently of the main processor in the RF Section (Al5
Controller). To enable the test pattern:
a. Jumper A3A6TP3 and A3A6TP6. (Turns on the test ROMs.)
b. Push A3A7Sl to initialize.
If troubleshooting without the RF Section or with the Analyzer Bus Interconnect cable W31
disconnected,
AlA8TPl
and
AlA8TP2
must be jumpered to turn on the power supplies.
If the CRT remains blank,
AlA6TP6
and
AlA6TP7
may have to be jumpered to inhibit the
CRT disable line controlled by the Al5 Controller.

A3A6TP5
disables interrupt and return inputs to the State Machine
Controller. The BS (Block Switch) line is forced to toggle at a
4 MHz rate.
The program addresses decrements in a binary sequence through all possible addresses with
the BS line toggling at 4 MHz, SO at 2 MHz,
Sl
at 1 MHz, and so on. This checks the A3A6
Main Control assembly, its ROM, Pipeline Registers, flip-flops and control pulses outputs, and
the
A3A7
I/O Port Decoder. To check the System ROMs, the same test setup is used but the
A3A6TP3
to
A3A6TP6
jumper is removed to re-enable the System ROMs outputs.
This test requires that the 8 MHz clocks, CLK and LCLK, and the initialize signal, LTON
from A3A7, be working.
This test also requires that a basic “kernel” be running. This includes part of the State
Machine Control (F) and the loop consisting of the Link Register, State Register, and Branch
Length Adder on A3A6. See “A3A6 Main Control, Troubleshooting” to troubleshoot this
circuitry.
Test Program 1
A3A6TP8

A3A6TP7

A3A5TP2
grounded disables the Register RAM outputs.
This program generates the pattern to test the A3A5 Data Manipulator, its Accumulator,
Control Decode logic, Pipeline Registers, and parts of its ALU, Constant ROM, and
Multiplexer Bus Drivers. This is the test that exercises the Digital Storage Bus with all
feedback from it disabled.
Test Program 2
A3A6TP8
grounded
disables qualifier feedback.
A3A6TP7
grounded
forces state machine interrupt high.
This program is the same as Test Program 1 except that the Register RAM outputs are
enabled on the
A3A5
Data Manipulator assembly. Since there is now feedback from the
Accumulator through the Register RAM, a bad bit will make all higher order bits appear bad;
so when probing the bus lines, the low order bits should be verified first and then higher order
ones. The program generates various patterns that are written into and read from register
RAM location 0; it also selects all the qualifier inputs on
A3A7
in both a low and a high state;
and it exercises all the bits in the branch length word on the A3A6 Main Control assembly.
This program is used to verify the Branch Length Adder on A3A6 Main Control assembly
when
A3A6El
jumper is replaced. On A3A5 it tests the Register RAM, ALU A inputs, and
the multiplexer inputs from the RAM
S
. And finally, it checks the qualifier select circuitry on
A3A7, so that the qualifier feedback can be used in generating the following test programs.

This program uses the Register RAM location 0 and the qualifier verified in Test Program 2
to generate a complete pattern test of all the Register RAM locations and Constant ROM
4 A3
words on A3A5. A pattern is also output to the X and Y line generator registers on A3A3.
The program does not read any input ports; Multiplexer Bus Drivers on A3A5 are the only

This is the overall check program used to test all the Digital Storage input ports. The
program generates the signals to check the memory, IOB data, IOB address, LTSTA, LTSTB,
and ADC inputs on the bus. For each input, a clock is selected corresponding to each input
putting data on the bus. This is done by positioning the jumper plug at the proper position in
the IC socket
A3A7Jl.
For example, to check Memory, the jumper is put at pin 3, connecting
pin 3 to pin 12. This program requires that the A3A5 Data Manipulator assembly be working
and the Digital Storage bus be good.

This program is used to generate a simple ramp waveform for the X and Y Line Generators
and also to generate simple repetitive control signals to the A3A9 Track and Hold assembly.
It is also used to check the Buffer on the A3A5 Data Manipulator assembly. The X and Y
ramp waveforms are 20 ms long when A3A2R12 is fully CW (long line) and 5 ms long when
A3A2R12 is fully CCW (short line). See A3A9 Troubleshooting for a diagram of the A3A9
control signals.

This program is almost identical to Test Program 5, except that the HOLD line to A3A9 is
normally high, going low to reset the hold capacitor and peak detectors only every 80 ms.
This can be used to check hold times. In addition, the CRT trace will be in the blink mode,
blinking once a second.
Figure l-2 shows the CRT displays for the various Test Programs. They are not meant to
verify that each test is running correctly, but rather to assure you that the test program is
cycling. With caution, they can also be used to do some short-cutting in the overall Digital
Storage troubleshooting procedure.
For example, the memory check, the IOB interface checks, the ADC check, Test A and Test B
checks should not be done if the Test Program 4 trace is not on the CRT. On the other hand,
if the traces for Test Programs 3, 4, and 5 appear correct, then the Main Control and Data
Manipulator checks could be temporarily bypassed and the memory or IOB interface checks
performed. (However, if these checks have bad inputs or the fault cannot be found, then the
A3A6 Main Control and
A3A5
Data Manipulator assemblies must be verified as shown in the
complete Digital Storage troubleshooting procedure.)

A3Al
A3Al
Trigger, Circuit Description
A3Al
Trigger contains circuits which generate the HSWP signal used by other assemblies in
the A3 Digital Storage section and in the spectrum analyzer RF section. Instrument Bus
commands set the HSWP line high or low, or program HSWP to go high when a sweep trigger
occurs. Trigger sources that may be selected are: the line, the video signal, or an external
trigger input from the instrument rear panel.
A3Al
Trigger contains circuits that select and
process trigger signals. It also contains the Fast Sweep Generator, which produces a linear
ramp voltage (0 V to approximately +2.2 V) used as a horizontal sweep for the CRT display.
This sweep ramp is used only with FREQUENCY SPAN=0 Hz. (It is not used to sweep the
RF Section frequency.)
The fast sweep ramp is applied to
AlA
X Deflection Amplifier or
AlA
XYZ Driver
Amplifier when selected by an analog multiplexer in A3A2 Intensity Control. The fast sweep
time may be varied in a 1, 2, 5 sequence from 10 ms (1 ms/div) to
1~s
(100
ns/div).
Trigger
circuitry used for the triggering of RF Section sweeps (by HSWP) is used to trigger fast
sweeps.
A3Al
also contains the Recorder
Penlift
Driver circuit, which is part of the High Sweep
Control.
High Sweep Control
@
The High Sweep Control circuit generates HSWP, which is a TTL open-collector signal that
is used by A3 Digital Storage to control signal tracking and conversion. HSWP is also used
in the instrument RF Section to control the Sweep Generator circuitry. The sweep ramp is in
progress when HWSP is high and is stopped (at any point during the sweep) when HSWP is
low. The RF Section can also pull HSWP low to stop the sweep under certain conditions. For
example, when a front-panel key is pressed, the main processor in the RF Section pulls HSWP
low (on Al2 Front Panel Interface) to immediately stop the sweep, then programs HSWP low
(on
A3Al
Trigger) with an Instrument Bus command before servicing the front-panel request.
HSWP must be set high again (on
A3Al
Trigger) for the sweep in the RF Section to resume.
HSWP is used directly to light the green front-panel SWEEP LED on the IF-Display Section.
This LED provides a very quick method of checking for activity on the HSWP line.
HSWP Generation
For HSWP to be high, flip-flop U12A pin 6 must be low. Inverter U7A buffers
U12A
and provides the open collector drive for the HSWP line.
U12A
is set and cleared by the
Instrument Bus and can be cleared by the RSHS signal from A3A6 Main Control. To set
HSWP, Instrument Bus bits 14 and 15 are set high, Address 50 is selected, and address
decoder U18 is enabled by LTIO (the IF-Display Section address strobe). U18, pin 13 goes
low, which clocks the U4A and
U4B
Q outputs high. The positive-going transition at the
U4B
output triggers a pulse of approximately 500
ps
at U9A pin 4. At the end of this pulse,
A3Al 1
U9B
generates a narrow (50 ns) pulse that clocks
U12A
and
U12B.
This causes
U12A
pin 6
to go low and HSWP to go high. (Note that HSWP is set high approximately 500
ps
after
occurrence of the Instrument Bus SET command. This time delay allows Al5 Controller to
perform certain functions before the sweep starts.)
To clear HSWP, Instrument Bus 13 is set high, Address 50 is selected, and (when the
IF-Display Section address strobe occurs) U12A,
U12B,
U4A, and
U4B
are cleared. HSWP
may also be cleared by other assemblies in the A3 Digital Storage when the RSHS line goes
low.
In Fast Sweep mode (sweep time setting
210
ms), HSWP is no longer used to control the RF
Section sweep ramp, since the spectrum analyzer is not sweeping the RF Section frequency.
It
is normal to see the green front-panel sweep LED turn off for these settings, even though the
CRT trace is sweeping.
Free Run Mode (for Sweep Time
220
ms)
When the RF Section is in Free Run mode with sweep time settings
220
ms, the sweep is
started when the Instrument Bus sets HSWP. The sweep is stopped by the RSHS line from
A3A6
Main Control or by a CLEAR command from the Instrument Bus. Al5 Controller
controls the time from the end of one sweep to the beginning of the next sweep (sweep dead
time).
Line, Video, and External Triggers (for Sweep Time
220
ms).
The RF Section can direct
A3Al
to set HSWP high when a line, video, or external trigger
occurs. If Instrument Bus line 14 is high and U18 is strobed with Address 50, U18 pin 13 will
go low, setting U4A pin 9 high, which triggers U94. At the end of the pulse generated by
U9B,
U12B
pin 9 will be clocked high, placing a high at the data input (pin 2) of
U12A.
The
output (pin 6) of trigger multiplexer U16 in the Trigger generator will then cause U12A to
be clocked on a negative-going transition of the selected trigger input. Refer to “Fast Sweep
Generator” in this chapter.
Recorder Pen Lift Driver
In sweep time settings
220
ms, the Recorder Pen Lift Driver supplies the PENLIFT signal to
the rear-panel PENLIFT connector. PENLIFT may also be used to control blanking of an
external CRT display.
PENLIFT is a 0 V to 15 V signal that lowers the recorder pen when an RF Section sweep
is in progress (HSWP is high, PENLIFT is 0 V) and lifts the pen when a sweep is not in
progress (HSWP is low, PENLIFT is 15 V). Decoder U3A is a noninverting buffer that drives
Q15 from the HSWP line.
Sweep Trigger
@
The Sweep Trigger circuit produces triggers for all sweep times. It contains the video,
external, and line trigger circuits, the fast sweep Free Run Oscillator, the trigger multiplexer,
and the fast-sweep Auto Trigger circuit. A valid trigger for the Fast Sweep Generator or the
High Sweep Control circuit is produced by a negative-going transition at the selected input of
trigger multiplexer U16. This trigger signal will start a sweep only if the Fast Sweep Control
and High Sweep Control circuits are in the proper states.
2 A3Al
Video Trigger
Video Trigger comparator U13 generates a negative-going transition when the VIDEO
signal rises above the voltage at U13 pin 2, which depends on the position of the front-panel
TRIGGER LEVEL control. R49, R50, and R51 divide the TRIG LEVEL voltage (0 V to
+5.1
V) to approximately -0.1 V to
+2.1
V at U13 pin 2. The LOW FAST SWEEP signal,
connected to the strobe inputs (pins 5 and 6) of U13, disables the output of U13 in Fast
Sweep mode when the fast sweep ramp is being generated. R52 provides hysteresis for U13,
and CR1 protects U13 from excessive input voltage on the VIDEO line. The
+lO
V and -10
V supply voltages for U13 are derived through VR4 and VR5.
External and Line Triggers
The EXT TRIG input from the IF-Display Section rear panel is applied to buffer/inverter
Q14 through divider R61 and R62. When EXT TRIG rises above approximately
+1.4
V, Q14
saturates and
U15C
pin 9 goes low, causing U16 pin 3 to go low, producing a trigger.
A voltage, resistively divided from a winding of the IF-Display Section line transformer, is
buffered by Schmitt trigger inverter
U15A,
the output of which is applied to U16 pin 2, the
line trigger input of the trigger multiplexer. Negative-going transitions at U16 pin 2 are valid
line triggers.
Free Run Mode (Sweep lime
5
10 ms)
In Fast Sweep mode, during the fast sweep dead time,
UllC
pin 8 is high. This causes
U15B
to oscillate at a rate (determined by R59 and Cll) of approximately 500
kHz.
Negative-going
transitions at
U15B
pin 6 produce triggers in the Fast Sweep, Free Run mode.
U15B
is gated
off during the fast sweep ramp. Note that the Free Run Oscillator is not used to trigger
sweeps in sweep times
120
ms. (See High Sweep Control circuit description.)
Fast Sweep Auto Trigger
When the
m
or
(J%Z]
key is pressed and the sweep time is 10 ms or less (Fast Sweep
mode), a fast sweep ramp will be started automatically about 25 ms after the start of the last
fast sweep if no video or external trigger occurs first.
If(e)
[El
or
(cl
(VIDEO)
keys are
pressed, fast sweep triggering will be in Normal mode. In Normal mode, no fast sweep will be
started until a trigger occurs. The CRT graticule and characters will not be refreshed until a
fast sweep has occurred.
Fast Sweep Auto Trigger Circuitry
In Auto Trigger mode, the Instrument Bus sets U5 pin 12 High.
UlA
pin 1 goes low when
the fast sweep ramp begins, triggering a 25 ms (low) pulse at
UlA
pin 4. If another fast
sweep ramp is started within 25 ms of the beginning of the previous fast sweep ramp,
UlA
will be retriggered, and
UlA
pin 4 will not go high for at least another 25 ms. If triggers
cease to occur,
UllD
pin 11 will go high 25 ms after the last fast sweep. This causes trigger
multiplexer U16 to select the output of the Free Run Oscillator in either Video or External
mode, triggering a sweep. Auto triggering will not occur in sweep times
220
ms, because in
this case the Auto Trigger circuitry is disabled by the FAST SWEEP ENABLE line to
UllB
pin 5.
If [SHIFT)
[E)
or (SHIFT]
[E)
keys are pressed, U5 pin 12 will be low, preventing automatic
triggering in the absence of
a
video or external trigger.
A3Al 3
Fast Sweep Time Control
@
Data on Instrument Bus lines 11 through 14 specify the fast sweep generator sweep time. This
data is latched into hex D flip-flop U6 when Address 51 is strobed. (Refer to the table, Note
6 on the schematic, for coding of the sweep time control lines.) Data on Instrument Bus line
15 is latched into U6 with the four sweep time bits
(IOBll-IOB14)
and enables fast sweep
generator operation.
Switchable Current Source
Current for the generation of the fast sweep ramp is supplied by Q13. Op amp U8 regulates
(through R6 and R7) the emitter voltage of Q13 to keep it equal to the reference voltage at
U8 pin 3.
QS
controls the reference voltage by switching R2 in or out of the voltage divider circuit,
which is made up of
Rl,
R2, and R3. The voltage difference between Q13 emitter and
+15
VFl
is set at 2 V when
QS
is off and 4 V when
QS
is on. The voltage difference is held
across a switchable resistance between Q13 emitter and
+15
VFl.
FET switches Q7,
QS,
and
Q9
connect resistors in parallel with R14 to change the current supplied by the current source.
When Q7,
QS,
and
Q9
are off, R14 sets Q13 collector current. In certain sweep times,
Q9
is
turned on by
U2C.
(Refer to the table on the schematic, Note 6.) This places
Rll
in parallel
with R14, increasing the current by a factor of 5. Similarly, R12 or R13 may be switched in
to increase current by factors of 10 and 50 respectively. Q7,
QS,
and
Q9
are controlled by
open-collector drivers
U2B,
U2A, and
U2C.
The FET switches are on when the FET gate
voltage is high
(+15
V) and off when the FET gate voltage is low (approximately
+0.2
V).
U3B
decodes the sweep rate control lines from U6 and controls U2A,
U2B,
and
U2C.
Fast Sweep Generator
@
To produce the fast sweep ramp for sweep times
5100
/.Ls,
current from Q13 charges timing
capacitor C4. For sweep times of 200
ps
to 10 ms,
Qll
is turned on, placing timing capacitor
C5 in parallel with C4, increasing the sweep time by a factor of 100. C4 and C5 (if it is in the
circuit) are discharged by
QlO
and Q12 at the end of the sweep.
Discharge Switch
When no sweep is in progress, the output of open-collector inverter
U7D
is high
(+5
V), and
current through R30 and R31 flow into
QlO
and through CR6 into Q12. In addition, current
flows from Q13 into Q12. At the start of a fast sweep ramp,
U7D
pin 8 goes low, and the
voltage at the anode of CR6 and the emitter of
QlO
is pulled slightly negative by R32. CR6
becomes reverse biased, and
QlO
turns off, turning Q12 off. Current from the collector of Q13
now flows into timing capacitors C4 and C5, and the sweep ramp begins. When the end of
the sweep ramp
(+2.2
V) is detected by the Fast Sweep Control circuit,
U7D
pin 8 goes high
(about
+5
V), turning
QlO
on. This turns Q12 on, and it begins to discharge C4 and C5.
Q12 continues to discharge the timing capacitors until CR6 becomes forward biased. At that
time, the circuit reaches equilibrium, holding the sweep ramp at near 0 V, with the offset
adjusted by R34.
Fast Sweep Buffer Amplifier
Op amp U14 is connected as a unity gain buffer amplifier, which provides the low impedance
fast sweep ramp output (FS OUT). FS OUT is applied to the X-axis scan multiplexer in
A3A2 Intensity Control.
4
A3A1
Fast Sweep Control
(6~
The Fast Sweep Control contains circuitry for end of sweep detection and controls fast sweep
dead time, and fast sweep triggering.
End of Sweep Detection
When the sweep ramp reaches about
+2.2
V,
Q5
conducts and turns Q4 on. When the
collector of Q4 goes low,
UlB
pin 5 produces a
pulse
whose length is the dead time. UlOA
and
UlOB
are cleared when UlOA pin 5 goes low, and timing capacitors C4 and C5 are
discharged by the Discharge Switch in the Fast Sweep Generator. Voltage divider
R19
and
R20 set the level at which Q5 senses the end of the sweep ramp. (Note that the fast sweep
ramp ends beyond the right-hand edge of the CRT.) The LRTRC line from UlOA pin 5, which
is high during the sweep, supplies the retrace blanking signal to
A3A2
Intensity Control.
Fast Sweep Dead Time
Multivibrator
UlB
controls the sweep dead time.
UlB
is triggered at the end of the fast
sweep ramp and holds
UlOA
and
UlOB
cleared for a time that is determined by C7, R24, and
R25. This prevents the triggering of further ramps for the length of the pulse from
UlB
pin
5. The length of the dead time is about 15
ps
for sweep times from 1
ps
through 100
ps
and
about 120
ps
for sweep times from 200
/.LS
through 10 ms. The ST 100
line
(from U6 pin 12 in
the Fast Sweep Time Control circuit) controls the length of the sweep dead time by switching
the
UlB
timing resistors with transistor switch Q3. In sweep times of 10 ms through 200
ps,
Q3 is off and the dead time, set by C7 and R24, is 120
ps.
In sweep times of 100
ps
through
1
ps,
Q3 is on, placing R25 in parallel with R24 to decrease the dead time to 15
,!Ls.
C6 and
R23 supply additional base drive to Q4 at the end of the sweep to insure triggering of
UlB.
Fast Sweep Triggering
Flip-flops UlOA and
UlOB
control the state of the fast sweep generator. UlOA controls the
Discharge Switch through inverter/buffer
U7D.
At the end of a fast sweep, both UlOA and
UlOB
are held cleared by the dead time circuit
(UlB
and U7F). Following the dead time,
a trigger from U16 pin 5 causes
UlOB
pin 7 to go low. This causes UlOA pin 5 to go high,
which turns off the Discharge Switch and starts a sweep ramp. This can occur only if FS EN
is high. If FS EN is low, the J and K inputs of
UlOB
are held low and a trigger
wiII
not set
UlOB.
Fast Sweep Multiplexing
In Fast Sweep mode, the X output of
A3A3
Line Generator and the fast sweep ramp must
be multiplexed to
AlA
X Deflection Amplifier or
AlA
XYZ Driver Amplifier to produce a
display consisting of the graticule and characters with the fast sweep ramp and the analog
video signal. The video
signal
from
A4Al
Video Processor is multiplexed to
AlA
Y
Deflection Amplifier or
AlA
XYZ Driver Amplifier when the fast sweep ramp is multiplexed
to
AlA
or
AlA2.
The X and Y multiplexers are located in A3A2 Intensity Control.
In Fast Sweep mode, the output from
A3A3
is applied to the CRT deflection amplifiers
following the completion of at least one fast sweep ramp.
A3A1
5
Fast Sweep Intensity Control @
To provide uniform intensity between the fast sweep trace and the other information displayed
on the CRT, the Fast Sweep Intensity Control circuit generates a voltage to control the CRT
beam intensity (Z-axis) when the fast sweep ramp is multiplexed in.
The FSZ voltage is dependent on the duty cycle of the fast sweep ramp; that is, the ratio
of time during which the ramp is in progress to the sum of dead time and sweep time. FSZ
varies from about 150
mV
(low beam intensity) for high duty cycle operation to about 2 V
(high beam intensity) for very low duty cycle operation.
The LRTRC line, high during the fast sweep ramp, provides a digital waveform which is
averaged and inverted by Q2, C15, and associated circuitry, providing an output voltage to
Ql
that is dependent on the average value of the LRTRC signal.
Ql
is an emitter follower which
provides drive when the FSZ signal is above
-
-150
mV
for low duty cycle sweep operation
(less than 20 percent). when the voltage at the collector of Q2 is below
+0.7
V (high duty
cycle operation), the base-emitter junction of
Ql
is off, and the FSZ voltage is held at about
150
mV
by voltage divider R71 and R72.
A3Al
Trigger, Troubleshooting
Much of the circuitry on the
A3Al
Trigger can be tested without removing the assembly from
the instrument. First key in Instrument Preset, (FREQUENCY SPAN) 0 Hz and
c-1

triggering.
The waveforms shown on the service sheet for TP2 and TP5 are valid only in the
(FREE]
and Normal mode
([SHIFT)
(VIDEO],
[SHIFT)
(EXT)).
The Fast Sweep time should be equal to
the time it takes the ramp at TP5 to sweep from 0 V to
+2
V. The oversweep above 2 V is
determined by the Sweep-Comparator and is not critical for instrument operation. The dead
time when the ramp and LRTRC are low is approximately 15
ps
for sweep times less than
200
ps,
and 120
ps
for sweep times from 200
ps
to 10 ms. During the dead time the Free Run
Oscillator is on. See Figure l-l for the relationships between the waveforms.

When using (LINE) TRIGGER, the waveforms are similar except for the dead time. Following

Figure 2. Fast Sweep Line Trigger Waveforms
If noise is used as a video trigger and the TRIGGER LEVEL control is properly set, the
[VIDEO)
trigger waveforms at TP5 and TP2 will be the same as those in Figure l-l. During the
minimum dead time period, the noise signal trigger will be present. If a video trigger does not
occur (TRIGGER LEVEL
control set fully CW or CCW), then the Auto Trigger circuitry will
generate a trigger approximately every 25 ms. TP2 and TP5 will have the relationship shown
in Figure l-2. If the voltage at U13 pin 3 is much less than U13 pin 2, then TP3 will be
approximately
+4
V. If the opposite is true, the waveforms at TP3 and TP2 will be the same.
If no fast sweep is occurring, check TP5 first. If the voltage is greater than
+2.6
V, the most
likely failure would be in the Fast Sweep Control circuitry. Refer to the circuit description for
operation of this functional block. An open Discharge Switch would also cause TP5 to remain
greater than
+2.6
V for all fast sweep times.
If TP5 is 0
f20
mV
dc and no fast sweeps occur, the Fast Sweep Control circuitry should be
examined. Other defective components that would cause the same indications are Q13 and
U7D.
The Sweep Trigger circuit may also be defective.
The Sweep Trigger circuitry can be tested by tracing the trigger signals through U16 to pin
13 of
UlO.
Try triggering first, as this is the simplest source. A TTL signal at the power line
frequency should be present at TP3. U7 pin 12 and the FAST SWP ENABLE line should
both be high. Also check for proper trigger signals at TP3.
Sweep times in the fast sweep time mode, being difficult to verify, require a precisely
modulated RF source. One quick troubleshooting method is to disconnect the white
@
cable
from A3A9J2 and connect it between A3A2J2 and
A3A2Jl.
This routes a 200
kHz
test
6 A3Al
waveform to the VIDEO TRIGGER and CRT Y-Axis Deflection circuits, allowing several
of the fast sweep times (10 psec to 200 psec) to be checked. Key in INSTR PRESET or

TRIGGER and adjust the
TRIGGER LEVEL control to display a two-cycle waveform; then, increase the

As an alternative, a function generator can be set for a 0.0 to 1.0 V dc, 100 Hz square wave
output, and then connected to
A3A2Jl
to check
all
the fast sweep times (1

A3A2 Intensity Control, Circuit Description
A3A2 Intensity Control provides the following functions:
n
It receives AX and AY signals from A3A3 Line Generator, approximates the line length,
and controls the Z-axis level to the display.
n
It sets and controls the duration of the Line Generator drawing period, which is either 4
pus
or 19
ps,
depending on the approximate line length.
w
It provides drive signals to Line Generator switches.
n
It controls all display blanking.
n
It multiplexes digital storage (Line Generator) X, Y, Z, and blanking with direct display of
fast sweep, video, fast sweep Z, and retrace blanking.
Intensity level is modulated as a function of AX and AY. The Line Generator Z-Axis circuit
receives AX and AY from
A3A3
Line Generator. The magnitudes of AX and AY are
summed together to approximate line length. The output of the Line Generator Z-Axis circuit
goes to the Bright circuit, which sets the Z-axis signal to maximum when bright lines are
drawn. The signal from the Bright circuit is multiplexed with the FSZ signal from
A3Al
Trigger and becomes the Z signal to the display. The Z signal also goes to the AUX Z circuit,
where Z and AUX BLANK are combined to form the AUX Z signal.
The line length approximation form the Line Generator Z-Axis circuit goes to the Long Line
Comparator, which decides whether the line should be drawn as a long line (19
ps
drawing
time) or a short line (4
ps
drawing time). This decision is stored at the Input Register
and sent to the A3A3 Line Generator as the LLL signal. It goes with LGCLK to the Long
Line/Short Line Timing circuit, which generates the timing signals necessary to control the
Line Generator setup and drawing periods. The signal INTR is used by A3A6 Main Control
to determine when to send new X and Y values to the Line Generator. The timing signals also
go to the Integrator Switch Driver and to the Sample and Hold Driver, which form the drive
signals needed for the Line Generator.
Control of display blanking begins at the Input Register. Blank and blink information is held
in the register during the line drawing period. The Blanking Logic circuit controls all display
blanking. It unblanks, blanks, or blinks lines as required by the Input Register. It multiplexes
digital storage blanking with fast-sweep retrace blanking.
Fast Scan Trigger Detect and Bus Buffer circuits are used to provide information to A3A6
Main Control to create the digital storage display.

1
Line Generator Z-Axis
@
AX and AY are received from A3A3 Line Generator.
U17
and associated circuitry is a
magnitude detector. For positive AX, CR1 is forward biased, U17 output goes negative, and
CR2 cathode is at 0 V. For negative AX, CR1 is reverse biased, U17 output goes positive,
and CR2 cathode is -AX volts (or/AXl).
S’
mce
R15=2R7=Rl,
the signal at CR5 anode due
to AX alone is
-lAXI.
When added to the output of the AY magnitude detector, the signal
at CR5 anode is
(-/AXI-lAYI),
hi h
w c is a rough approximation of line length. The signal at
CR7 anode is equal to the signal at CR5 anode except when CR5 anode is more positive than
-0.1 V. R16 and R17 prevent CR7 anode from rising above -0.1 V.
The line length
signal(-lAXI-lAYI)
is sampled by U5 during the setup period of A3A3 Line
Generator. Switches Q2 and Q4 are closed during sampling. The signal is held on C3 during
the drawing period. Switches
Ql
and Q3 are closed during the hold mode.
For dim lines, the DIM signal is high, and switch A of analog switch
UlA
is closed to lower
the gain of the Sample and Hold circuit.
UlA
switch D is closed during long lines (19
ps
drawing period).
Bright
@
For bright lines (BRIGHT signal high), switch C of
UlB
is closed to set the signal LGZ to
+2
v.
Digital Storage/Fast Scan
MUX
@I
This circuit provides multiplexing between the digital storage display (Line Generator) and
the fast scan display (video and fast sweep). For the digital storage display, LGX, LGY, and
LGZ are connected to X, Y, and Z by U15 and U14. For the fast scan display, FS OUT (fast
sweep output), VIDEO, and FSZ (fast sweep Z axis) are selected.
Long Line Comparator
@
The Long Line Comparator receives the line length approximation from CR7 cathode and
compares it with the long-line threshold (LL THRESHOLD adjustment
high when the approximation has greater magnitude than the threshold.R12). U4 pin 7 goes
Input Register
@
The signal from the Long Line Comparator and line intensity information are stored in the
Input Register when a positive edge occurs on the INTR line. The Input Register is updated
for each line drawn on the display. Signal FS is used to select the fast scan display (fast sweep
and video).

A3A2
Blink
@
The output of U12 is a 1 Hz signal with a 90 percent duty cycle. When enabled by the
BLINK command stored in the Input Register, this signal causes display blinking.
Long Line/Short Line Timing
@
This circuit receives signal LGCLK from
A3A7
Interface and signal LL from the Input
Register. It generates signal INTR, which is a string of 1
ps
pulses. When LL is low the
pulses are spaced 5
ps
apart; when LL is high the pulses are 20
ps
apart. This provides the
timing signals for the 4 and 19
11s
Line Generator drawing periods and 1
ps
setup period.
Integrator Switch Driver
@
This circuit provides the drive signals for the Integrator switches in A3A3 Line Generator.
Q13 and Q14 form a complementary driver. When the input is low, Q13 is on and Q14 is off,
setting INTG to -5 V and LINTG to 4.7 V nominal. When the input is high, Q13 is off and
14 is on, setting INTG to +7.3 V nominal and LINTG to -5 V.
Sample and Hold Switch Driver
GJ
This circuit provides the drive signals for the Sample and Hold circuits of the Line Generator
X, Y, and Z axes.
QlO
and Q12 form a complementary driver. A -9.6 V reference is provided
by
Qll
and associated circuitry.
Q9
is a level translator. When
Ull
pin 11 goes low,
Q9
collector goes to
-10.3 V, turning
QlO
off and Q12 on. Signals HLDX and HLDY go to 0 V,
and signal SMPL goes to -7.6 V nominal. When
Ull
pin 11 goes high,
Q9
collector goes to
-8.9 V, turning
QlO
on and Q12 off. SMPL goes to 0 V and
QlO
collector goes to -8.4 V
nominal. Potentiometers R50 (X S&H BAL) and R51 (Y S&H BAL) are used to adjust the
HLDX and HLDY drive levels to A3A3 Line Generator. Cl8 and Q5 speed the rise time of
the HLDX and HLDY signals. As
Ull
pin 11 goes from high to low, the base of
Q5
goes low,
causing Q5 to turn on and the HLDX and HLDY signals to rise almost instantaneously.
Blanking Logic
@
This circuit provides all display blanking. It muliplexes the retrace blanking of the fast scan
display (direct video and fast sweep) with the digital storage blanking. For the digital storage
display it provides blanking or unblanking as specified by signals LLGBLANK, BLINK,
DOTEN, and INTR. R30, R27, C16, R28, R32, and Cl5 are delay circuits which match the
delay of the LBLANK signal to the delay of the Line Generator. R31, R29, and Cl4 match
the retrace blanking delay to the fast sweep delay.
AUX Z
@
The AUX Z circuit receives the LBLANK signal from the Blanking Logic and the Z signal
from the Digital Storage/Fast Scan M
UX
. It generates the AUX BLANK and AUX Z signals.
R65 and R62 convert the 0 to 2 V range of Z to the 0 to 1 V range necessary for variation of
AUX Z intensity. U8 is a voltage follower with
QS
providing a high current output.
Blanking causes the AUX Z signal to drop to -1 V or less. When AUX BLANK goes high,
Q7 turns off and
QS
turns on, causing AUX Z to go negative. When AUX BLANK IS LOW,
Q7 is on and
QS
is off.
A3A2
3
Fast Scan Trigger Detect
@I
This circuit is used to detect the occurrence of a fast scan trigger. When LRTRC, the retrace
signal, goes high, a fast scan has been triggered. Flip-flop
U18B
is set by the positive edge of
LRTRC.
U18B
is reset by LRSTO.
Bus Buffer
(ij
This circuit buffers status signals onto the Digital Storage Bus.
A3A2 Intensity Control, Troubleshooting
The
A3A2
Intensity Control Assembly modulates the Z-Axis intensity, controls the A3A3 Line
Generator drawing period, controls the display blanking, and multiplexes Digital Storage with
the fast sweep video for sweep times less than 20 ms.
Digital Storage Test program 4 is used to troubleshoot this assembly. Table l-l lists the
voltages that are present at various nodes in the Line Generator Z-Axis
0.
Depending on
the persistence of the oscilloscope, the waveforms will appear either as dots or vertical line
segments. If any of the sample and hold FETs
A3A2
Ql
to Q4 are defective, it is easier to
replace all four than to isolate the defective component.

Disabling the blanking signal can be helpful when troubleshooting labels that are shifted from
their proper positions. This is done by grounding one input to
U7D.
This can be accomplished
without removing the board by running a jumper from ground to A3A2R32, the resistor
nearest to the
LG/FS
CAL connector, A3A2J2.
The following program draws either a horizontal or a vertical line on the CRT. It is useful for
troubleshooting problems associated with dynamic operation of the Z-Axis Line Generator. A
better understanding of the operation of the Z-Axis Line Generator will be gained by keying
in this program and observing the waveforms while reading the circuit description.

A3A3 Line Generator, Circuit Description
A3A3 Line Generator receives a series of digital X and Y display positions, converts them
to analog values, and connects them with straight lines. This process, called line generation,
is similar to that of dot-to-dot drawing on paper. (See Figure 1.) Two independent line
generators are required: one for the X series of values and one for the Y series. For each line
there is a setup period following by a drawing period. During the setup period the display is
blanked by
A3A2
Intensity Control.

DRAWING PERIOD
Figure 1. Line Generation Process
Each of the line generators consists of a register, a digital-to-analog converter (DAC), a
summing amplifier, a sample and hold circuit, an integrator, and a filter. The X or Y register
receives the next display point from the Digital Storage Bus. The DAC converts this number
to a current. The summing amplifier then computes a position change AX = “next X”
-
“present X.” During the setup time for the next line, AX and AY are sampled by the Sample
and Hold circuit. At the end of the setup time and during the drawing time, AX and AY are
held for constant input to the Integrator. During the drawing time, the Integrator output
changes linearly from X to X + AX and from Y to Y + AY. This is done by integrating AX
A3A3
1
and AY at a constant rate such that the output becomes X + AX and Y + AY; that is, “new
X”
and “new Y.”
X Register
@
U5 and U6 form a
lo-bit
X Position Register. When a new X position is present on lines
BO-B9
of the Digital Storage Bus, the CHAR line is held low and a positive-going edge on
LDX causes U5 and U6 to be loaded with the value of
BO-B9.
These 10 bits then become the
X position input to the X DAC. Characters are drawn by changing only bits 1, 2, and 3 of the
X Position register and bits 1 through 4 of the Y Position Register. Strokes of a character
are described by a series of X and Y values sent to the Line Generator on the Digital Storage
Bus. B4-B6 of the Digital Storage Bus carry the series of X values. When the next X value is
present on B4-B6, the CHAR line is held high and a positive-going edge on LDCHAR caused
U5 to be loaded with the new values for bits 1 through 3 of the X position.
X DAC
@
The output of U5 and U6 are the X position input to U4, the X DAC. U4 is a
lo-bit
multiplying DAC whose output current depends on the digital input code and the voltage
at VREF (pin 15). This output current is the analog X position sent to the X Summing
Amplifier. The inputs of U4 are clamped to a maximum of
+3.6
V by diodes CR1 through
CRlO.
X Summing Amplifier
GJ
The X Summing Amplifier receives the next X position from the X DAC, the present X
position from the X Integrator, and an X position shift from the Expand Register. The
three signals are summed to give AX =
“next X” + “X shift”
-
“present X.” “X shift” is a
binary signal of 0 V or
+5
V, and the amount of shift is adjusted by X EXP potentiometer
Rl
(X and Y shift are used to move the display origin from the graticule lower left to the
screen lower left). X GAIN potentiometer R4, the X line generator gain adjustment, varies
the magnitude of the X line generator output. R4 also has an effect on the accuracy of line
positions. XLL potentiometer R6, the X long line adjust, is used to adjust line position
accuracy. (See Integrator description.)
X Sample and Hold
@I
The AX value from the Summing Amplifier is held for constant input to the Integrator by
the X Sample and Hold circuit. Sampling occurs during the setup period, which lasts 1
ps.
Holding occurs during the drawing period, which lasts 4
ps
or 19
ps.
Q2 and Q3 are on
during the sample mode and are driven by the SMPL line.
Ql
and Q4 are on during the hold
mode and are driven by the HLDX line. (See Figure 2.) Q6 is a dual FET used to provide a
high-impedance input to U2. Capacitor C23 is the holding capacitor.

SAMPLE MODE HOLD MODE
Figure 2. Sample and Hold Modes, Simplified Schematic
X Integrator
@
Ul,
C26, and Q5 form an “integrate and hold” circuit whose output is the X display position.
During the setup period, Q5 is open, leaving only
Ul
and C26 holding the present value of
X. During the drawing period, Q5 is closed and the constant AX value from the Sample
and Hold circuit causes a constant current (proportional to AX) to flow through C26. This
constant current through C26 causes the output of
Ul
to change linearly from the value (Xi)
at the last setup period toward a new value
Xi
+
r
=
Xi
+ AX. When the drawing period
ends, Q5 opens and the circuit returns to the hold mode, this time with output at the new X
position, Xi. The process of current flow through C26 is equivalent to integrating AX over the
drawing period.
The drawing period may last for 4
/.LS
(short line) or 19
ps
(long line). The hold period lasts
for 1
,xs.
When the Line Generator is drawing a long line (19
ps),
switch
QS
is open and the
current through C26 is determined by R15. When the Line Generator is drawing a short line
(4
ps),
switch
QS
is closed and the current through C26 is determined by
R15
in parallel
with R7, R18. In either case, the current must be precisely set so that the X position will
become
Xi
+
r
=
Xi
+ AX at the end of the drawing period. In the long line mode, XLL
potentiometer R6 of the Summing Amplifier is adjusted to get accurate line positioning. For
accuracy in the short line mode, XSL potentiometer R18 must be properly adjusted.
Diodes CR22 and CR23 keep the source of Q5 within 0.7 V of ground during the hold mode.
Capacitors C43 and C27 and signal LINTG compensate for gate feedthrough on Q5. R16,
C29, and C28 provide frequency compensation for
Ul.

X Filter
@
The X Filter is a 2.5 MHz low-pass filter which smooths out transients from the X Integrator.
Y Register
@
U9
and
UlO
form a lo-bit Y Register. When a new Y position is present on
BO-B9
of the
Digital Storage Bus, the CHAR line is held low and positive-going edge on LDY causes
U9
and
UlO
to be loaded with the value of
BO-B9.
These 10 bits then become the Y position
input to the Y DAC. When characters are being drawn, bits 1 through 4 of the Y Register are
changed. BO-B3 of the Digital Storage Bus carry the series of Y values representing the Y
components of the character strokes. When the next Y value is present on BO-B3, the CHAR
line is held high and a positive-going edge on LDCHAR causes
U9
to be loaded with the new
values for bits 1 through 4 of the Y position.
Y DAC, Y Summing Amplifier, Y Sample and Hold, Y Integrator,
and Y Filter
@
0
@
@
@
The Y DAC, Y Summing Amplifier, Y Sample and Hold, Y Integrator, and Y Filter operate
in a manner identical to that of the corresponding X Line Generator circuits.
Expand Register
@
U14 is a 2-bit Expand Register which provides scale and origin-shift information to the X and
Y Line Generators. When a new expand value is present on B6 and B8 of the Digital Storage
Bus, a positive-going edge on LDEXP causes
U14
to be loaded with the value of B6 and B8.
A high on B6 will cause a scale increase of 13 percent over normal (the graticule is drawn
at normal scale) and an origin shift of 13.6 percent of normal scale.
Q16
and Q17 provide
buffering from the TTL signals to the analog circuits.
Reference
@
U13 provides the reference voltage to the X and Y DACs. The magnitude of the reference
voltage is proportional to the scale of the Line Generator output. For normal scale the
reference voltage is nominally -5.12 V. For the three expanded scales, the reference may be
-5.8 V, -7.9 V, or -8.6 V.
Y Offset
@
The Y Offset circuit supplies a signal to the Y Summing Amplifier such that the output of the
Y Line Generator will be 0 V when the Y Register contains all zeroes and no origin shift is
present. YOS potentiometer R43 is used to make the adjustment.

A3A3
Long Line Switch Driver
@I
The long Line Switch Driver provides level translation from the TTL signal LLL to the gate
signals for Q7 and
QS.
A high on LLL turns on Q7 and
QS.
Line Generator liming
Figure 3 shows the timing relationship between the X and Y Line Generator outputs and the
drive signals. Changes in the X Register, Y Register, and Expand Register Occur only during
the drawing period; that is, when the Sample and Hold circuit is holding. Changes in the LLL
signal occur only during the setup period; that is, when the Integrator is holding. The length
of the drawing period (either 4 or 19
,US)
is determined by A3A2 Intensity Control.

A3A3 Line Generator, Troubleshooting
The A3A3 Line Generator Assembly converts the digital X and Y display positions from the
Digital Storage processor to analog values and draws lines between them. It positions the
characters with respect to the graticule and sets the size of the display and graticule.
A distorted CRT display involving both the horizontal and the vertical components is often
caused by malfunctions on this assembly. If only the video information is distorted, suspect
the A3A8 Analog Digital Converter. Drawing of the characters is controlled by the Character
Stroke Memory on the
A3A4
Memory Assembly.
If both the X and Y channels are distorted, suspect the Expand Register
@,
Reference
0,
Long Line Switch Driver
@
and/or the INTG or SMPL control signals, as these are common
to both channels.
If the positive amplitude at
A3A3TPll
is only $2 V, the gate of either Q5 or
QlO
has been
damaged.
The Long Line switches Q7 and
QS
can be tested as follows. Set A3A2R12 in the LL position
(full CW).
A3A3TP6
is then a TTL low and the gates of Q7 and
QS
are approximately
-15 V. With
A3A2R12
in the fully CCW position, A3A3TP6 is a TTL high and the gates of
Q7 and
QS
are approximately -1 V.
If it is determined that any of the Sample and Hold FETs
Ql
through Q4 or
Q12
through
Q15
are defective, the best procedure is to replace all four since it is not easy to determine
which FET is defective.
The Digital Storage Test Programs can be used to troubleshoot the analog functions on A3A3.
When using these programs, the
LL/SL
pot
A3A2R12
should be set to the full CW position
(LL). The SL (full CCW) position should also be examined as it exercises the circuitry at the
highest speeds.
Digital Storage Test Program 5 and the CRT display are used to verify the input Registers
and the DACs. It is not necessary to remove
A3Al
when testing A3A3. The display in Figure
4 is the result of a Y DAC or Y Register malfunction. Notice that the malfunction causes
vertical jumps in the test waveform. A defective component in the X channel would cause
horizontal jumps.

set the
VREF
levels for the X and Y
DACs.
This
provides both magnification and origin shift for the display. As shown in Table 1, four voltage
levels are generated. These levels are present when Digital Storage Test Program 3 is used
(again it is not necessary to remove
A3Al).
The reference voltage is measured at
A3A3TP8.
With A3A2R12 in the LL position and the oscilloscope sweep time set to 2 ms/div, the
waveform shown in Figure 5 will result. In the SL position the waveform is identical for a
sweep time of 1 ms/div.

The waveforms in Figure 6 show the X and Y channel outputs for this program.
The +5 V pulse at A3A3TP12 is the “next X” data from the X DAC. In this program the
“X shift” value from the Expand Register is 0 V. The “present
X”
value is the waveform of
A3A3TPlO. The ouput at A3A3TP12 is AX = “next
X”
+ “X shift”
-
“present X.” The
small spikes every 5
j~s
indicate the beginning and end of the 1
/.LS
sampling period.
A3A3TP4
shows the output of the Sample and Hold circuitry. Note that the output is inverted relative
to the output of the summing amplifier.
A3A3TPlO
shows the result of integrating AX over the drawing period. See
“A3A3

Memory, Circuit Description
Memory Assembly
A3A4
contains 4096 12-bit words of static random-access memory (RAM)
and 2048 8-bit words of read-only memory (ROM), plus the necessary latches, buffers, and
control logic for input and output operations. Data for display annotation (center frequency,
reference level, and so on.), graticules, characters, and TRACE A and TRACE B is stored in
memory.
Display Memory
@
Display memory contains two 2 k x 12 blocks. The lower block, made up of U4 and U5,
corresponds to addresses 0000 through 2047 and is enabled by
LCEl
from Control Logic. The
upper block, U3 and U6, corresponds to addresses 2048 through 4095 and is enabled by LCE2.
Four of the eight input/output lines of U5 and U6 are not used since only
12-bit
data words
are required. LOE enables the RAM outputs for read operations only. LWE writes data to
the RAM.
The RAM address latches, U7 and U8, store the memory address during read and write
operations. These latches are required because the memory address register is occasionally
changed before a read operation is completed. When not enabled, these latches are
transparent.
Memory Address Register
@
Registers
U15
and
U16
store the memory address for display memory and character stroke
memory.
Memory Data Input Register
@
Registers
U9
and
Ull
store input data to be written to the display memory for write
operations only.
Buffers
UlO
and U12 pass data from Memory Data Input Register to display memory for
write operations only.
Memory Data Output Buffer
@
Buffers
U13
and U14 enable the output data from either display memory or character stroke
memory to the Digital Storage Bus for read operations only.
A3A4

Control Logic
@j
Control Logic generates control signals for display memory and buffers in Memory Data Input
Register. When control line CE (chip enable) is true, RAM address 11
@All)
from U7
generates low chip enable 1 and 2
(LCEl,
LCE2). Thi
s
enables the lower or upper block of
display memory during read and write operations.
During read operations, LOE (low output enable) is generated in
U17D
when CE is true
and LWRITE (low write) is false. During write operations,
U17C
produces LWE (low write
enable) when CE and LWRITE are true.
Inverters
U18E
and
U18D
produce LDINEN (low data input enable) when LWE is true. The
two inverters delay the rising edge of LDINEN to hold the data lines after LWE goes false, at
the end of a write operation.
Character Stroke Memory
@
ROM U2 is a 2048 word by 8-bit read-only memory that contains the relative X and Y axis
coordinate information that forms displayed characters. Each 8-bit word contains three bits
of X-axis information, four bits of Y-axis information, and one bit for blanking. The ROM is
addressed from the memory address register and the stroke counter. The ROM outputs are
enabled by LROMEN (low ROM enable).
Stroke Counter
@
The stroke counter drives the lower three address bits of character stroke memory. Since
most characters contain less than eight line segments, the character information is stored in
consecutive 8-word blocks in the ROM. The memory address register contains the address of
the 8-word block while the stroke counter contains the address of the individual strokes. To
read the information for all the line segments of a character, the memory address register is
held constant while the stroke counter addresses up to eight strokes.
The STROK8 output goes high to signal the processor that the eighth stroke has been
reached. LCLRSA clears the counter at the beginning of each character and INCRSA is used
to increment the counter after each stroke.

A3A4
Memory, Troubleshooting
Test Program 4 is used to write and read various patterns from the Display Memory
@
and
to read the Character Stroke Memory
0.
An explanation of Test Program 4 is located in the
“A3 Digital Storage Troubleshooting” tab. This test requires that the Digital Storage input
bus be good (there are no shorted Digital Storage data lines). This could show up as incorrect
inputs to the memory address registers U15 and U16.

12-bit
RAM registers used for data storage during data
manipulation.
Constant ROM
@
Ul
and
U18
form the 16 12-bit ROM registers used as constants for data storage during data
manipulation.
Accumulator
@I
U7 and
U9
form the
12-bit
Accumulator, which receives and holds all results of ALU
operations.
Buffer
@
U5 and
Ull
are three-state data buffers that allow the Accumulator data to be transferred to
the Source Bus.
Arithmetic Logic Unit (ALU)
@
U2, U3, and U4 are the main Arithmetic Logic Unit (ALU).
U16
provides high-speed carry
look-ahead.
U14
decodes ALU outputs to determine whether a zero-value result has been
generated.
Pipeline Register
@
U12 and U24 form an instruction Pipeline Register for data manipulation instructions.
A3A5
1
Control Decoder
@
U19
through U23 decode data manipulation instructions into the necessary control lines.
Multiplexer/Bus Driver
@
U6, U8, and
UlO
form a 12-bit Bus Driver with two data inputs. Data from the RAM Bus or
from the Accumulator Bus may be transferred to the main Digital Storage Bus through these
drivers.
A3A5 Data Manipulator, Troubleshooting
To verify proper operation of A3A5 Data Manipulator, first use Test Program 2, with the
qualifier feedback disabled, to verify the qualifier select circuitry on A3A7. The next check
uses Test Program 3 to check the Data Manipulator Bus output at the connector and the
LZERO output at U14 pin 9. (Since Test Program 3 is the first program to use the qualifier
and the normal interrupt, the INTR line from
A3A2
to A3A6U16 pin 10 and the buffered
qualifier A3A6U27 might have to be checked. The INTR line should be a 50
kHz
signal.)
On all previous checks, they have not been enabled, so that the Source bus was always the
Constant ROM output. Test Program 5, though, enables U5 and
Ull
so they can be checked.
This also checks that the Constant ROM outputs can be disabled.
Test Program 1 checks the Accumulator, Control Decode logic, Pipeline Registers, and parts
of the ALU, Constant ROM, and the Multiplexer Bus Driver. The Register RAM outputs
are disabled by
A3A5TP2
being grounded; thus, they should be high. This eliminates the
feedback from the data bus back into the
A3A5
Data Manipulator.
Troubleshooting the Digital Storage Bus
If a Multiplexer Bus Driver on A3A5 has an incorrect output but all its inputs are good, the
multiplexer may be defective or there may be another bad driver/load on that data bit. If
replacing the multiplexer does not solve the problem, additional probing with a scope, current
tracer, or ohmmeter may be required to further isolate the bad node.
Test Program 2 is the same as Test Program 1 except that the Register
RAMS
are enabled.
This feedback path means that a low-order bit failure can make higher-order bits appear bad.
Therefore, it is best to probe beginning with bit 0 and then working up. If a register RAM
output appears incorrect, it may be due to either the RAM being defective, or the ALU input
being faulty. Grounding
A3A5TP2
disables the RAM outputs, and the ALU input is verified
by manually grounding the RAM output.

A3A6 Data Manipulator Component Locations, 85662-60145
A3A6
A3A6
Main Control, Circuit Description
The Digital Storage Processor is controlled by an algorithmic state machine, which uses
relative-state addressing and interrupt linkage in performing the control algorithm. The
Digital Storage Processor includes
A3A4
Memory,
A3A5
Data Manipulator, A3A6 Main
Control, and
A3A7
Interface.
State Register
@J
The State Register,
U13
and
U14,
contains the present state of the algorithm. The present
state data is supplied to the Program ROM (Read-Only Memory), where it is decoded into
control functions.
Branch Length Adder
@
The Branch Length Adder,
Ul
and U2, receives branch length data from the Program ROM
and adds it to the present state data to generate the next state.
Link Register
@
The Link Register, U12 and U15, holds the suspended state of the main program during
interrupts and holds the next interrupt state during the main program.
In effect the Link Register acts as a “bookmark” for both the main program and the interrupt
program, so that either program can resume at the correct state.
State Machine Control
@
The State Machine Control,
U16,
U17, U18,
U27C,
and
U27D,
manages switching between
the main and interrupt programs. In addition, it generates a signal to increment the Branch
Length Adder for conditional branching.
Program ROM
@
The Program ROM, U4, U6, U8, and
UlO,
contains both the main program and the interrupt
program. U5, U7,
U9,
and
Ull
are test firmware used to generate diagnostic tests.
A3A6
1
Pipeline Registers
@
@
The Pipeline Registers, U24 and U28, hold instructions from the Program ROM for 125 ns
during execution.
Addressable Flip-Flops
@
U21 and U23 contain 16 flip-flops that may be individually set and cleared. These flip-flops
control signals for the Input Section and CRT Driver Section of A3 Digital Storage. The
Input Section includes A3A8 Analog-Digital Converter and A3A9 Track and Hold. The CRT
Driver Section includes
A3Al
Trigger, A3A2 Intensity Control, and
A3A3
Line Generator.
The flip-flops also control flags and memory control lines for the Processor Section, which
includes
A3A4
Memory, A3A5 Data Manipulator, A3A6 Main Control, and
A3A7
Interface.
U19,
U27A, and
U27B
decode instructions from Pipeline Register U28 to control the 16 flip
flops. U29 contains buffers to output flag and timer signals onto the Digital Storage Bus.
Control Pulses
@
U26 decodes eight control pulses based on the instruction in the Pipeline Register U24.
U25A
is a
flip-flop
that is set and cleared by the signals decoded by U26. U26 controls the reset of
peak detectors in the Input Section of A3 Digital Storage.
Dual Timer
@I
U20
provides two timing pulses. One, about 20 ms, controls the CRT refresh rate. The other,
about 20
/.Ls,
is used in the digital peak detection algorithm.
RAM Chip Enable Generator
@
U22 generates chip enable timing for A3A4 Memory. It delays execution of program
instructions
l-1/2
states (182.5 ns) to allow addresses to settle.

Troubleshooting
The INTR and LQ inputs, such as U16 pin 10, are checked simply for activity.
The Free Run check is done with
A3A6TP8
grounded. This forces U27 pin 11 high and U18
pin 6 low. To verify these components and the
Ul
adder input, this ground is removed.
The Free Run check setup is used to verify the System ROM.
After A3A5 and
A3A7
have been checked, the LTSTA and LTSTB lines are verified by using
Test Program 4.

A3A7
A3A7 Interface, Circuit Description
A3A7
Interface provides data transfer between Al5 Controller and A3 Digital Storage. This
assembly also includes qualifier selection for
conditionaI
branching, input/output (I/O) port
decoding, and the main clock circuits.
Data Transfer Register
@
U2, U7, U8, and
U9
form a 16-bit Data Transfer Register which can be loaded or output onto
either the Instrument Bus (through
U16
and
U17,
the Instrument Bus Drivers) or the Digital
Storage Bus (through U3, U4, and U5, the Digital Storage Bus Drivers).
Instrument Address Decoder
@
U6, U14, and U15 control the loading and output of data between the Data Transfer Register
and the Instrument Bus.
Qualifier Select
@
U20
and U21 select one of 16 qualifiers to be used for conditional branching. Selection is
controlled by A3A6 Main Control firmware.
I/O Port Decoder
@I
U18 and
U19
decode I/O port control signals from the Pipeline Registers in A3A6 Main
Control.
Timing Generator
@
UlO,
Ull,
U12, and U13 generate 8 MHz, 1 MHz, and 200
kHz
timing signals used by A3
Digital Storage.

A3A7
Interface, Troubleshooting
The
A3A7
Interface assembly contains several different circuits. Testing the Timing Generator
and Turn-on Control is probably best done with an oscilloscope to monitor the 8 MHz, 1
MHz, and 200
kHz
outputs. The Qualifier Select circuit is checked, along with the A3A5 Data
Manipulator assembly, using Test Program 2. The Digital Storage address check uses the
self-check routine from the Al5 Controller in the RF Section.
The IOB interface circuitry is checked using the overall Test Program 4. The 50-wire
Analyzer Bus Interconnect cable W31 is removed so that the U16 and U17 Bus Drivers
@
can
continually drive the IOB lines when
A3A7TP8
is grounded. To check the data portion of
the interface, the jumper is moved to pin 7. If a fault is found in verifying the data at the P2
connector, the jumper El is opened before probing U3 to
U9.
This opens the feedback from
the Data Transfer Registers
@
through the Bus Driver
@
and back to the register
@.
If all
the Bus Driver
@J
outputs and the Digital Storage Bus Driver
@
outputs are good when the
jumper is opened, then the fault is in the register corresponding to the bad bit detected at the
connector; that is, its IOB input is defective.
If the fault appears to be a bus fight problem (the Al5 Controller cannot properly drive the
IOB data lines until A3A7 is removed), then the problem might be that the Bus Driver
@J
will not go into its high impedance output state. This can be determined by checking with an
oscilloscope the IOBO-11 lines with the Analyzer Bus Interconnect cable disconnected and
with
A3A7TP8
not grounded. The lines should be “floating,” usually between 1.4 V and 2 V.
With the Analyzer Bus Interconnect cable disconnected,
AlA8TPl
and
AlA8TP2
must be
jumpered to turn on the power supplies.

Analog-Digital Converter, Circuit Description
A3A8 Analog-Digital Converter converts the analog VIDEO signal from A3A9 Track and
Hold into storable digital data for A3 Digital Storage. The important data and control lines
are: all Digital Storage Bus bits,
BO-Bll,
which are used for data inputs and outputs, ADC,
which loads final ADC data onto the Digital Storage Bus; HOLD, which resets the ADC and
initiates a conversion; LD RMP, which updates the Ramp DAC with a new scan address; and
LTSTA, which enables test bits (BO,
Bl,
and B2), RAMP, LTRK, and BUSY onto the Digital
Storage Bus.
ADC
@
The ADC (analog-to-digital) circuit converts analog (sampled video) data from
A3A9
Track
and Hold onto 10 bits of binary code using the technique of successive approximation. A
simplified schematic of the ADC circuit is shown in Figure l-l.
*JlgTi;;I
B-w-+
,,N
OUTPUT
HOLD ‘BUSY’
Figure 1. A3A8 Analog-Digital Converter, Simplified Schematic
The ADC circuit consists of digital-to-analog converter (DAC)
Ull,
comparator U12, and
successive approximation register U13. A 1 MHz clock fixes conversion time at 11
ps.
To
A3A8
1
begin a conversion, the ADC is first reset to ones by a low HOLD. When HOLD goes high,
each bit is individually tried in a “trial” conversion, starting with the most significant bit. A
decision is made to retain or drop the bit based on the comparator output. Once the decision
has been made for each of the 10 bits, a “conversion-complete” signal sets the
flip-flop
U14A.
This signal, called BUSY, can be transferred onto the Digital Storage Bus by the BUS Buffers
u15.
Ramp Converter
@
The Ramp Converter makes a comparison between the analog sweep signal and the scan
address (X Axis). Comparator
Ul
makes this comparison and produces a signal called RAMP.
RAMP high indicates that the scan address needs to be updated. When RAMP is low, no
update is needed. When an update occurs, a new address is latched into the Scan Address
latches
U9
and
UlO.
This results in an updated comparison between the output of DAC U5
and the Sweep input as shown in the simplified schematic (Figure l-2). A reference voltage is
created for the DAC by
VRl
and U3. This voltage is adjustable by R5 to set the full-scale
(+lO.OOO
V) sweep ramp point at the 1000th data “bucket”; the rightmost edge of the CRT
trace. Amplifier U2 sums the currents from the DAC U5, the sweep input, and ZERO stick,
and drives the comparator input. OFFS is adjustable by R6.

A3A8 Analog-Digital Converter, Troubleshooting
The
A3A8
Analog Digital Converter converts the analog video and sweep voltages to digital
data. Consequently, a failure on this assembly will affect the display of trace A and trace B
data. Character and graticule generation are not affected by A3A8.
Stuck bits in the Ramp Converter will distort the displayed signal. This is most easily
observed with slow sweep times. When a bit fails, the Ramp Converter will default to a 20 ms
sweep rate during the display period when that bit would normally be working. Figure 1-3 is
an example of the CAL OUTPUT signal with a 3 s sweep time when U5 pin 5 is struck low.

Figure 3. Ramp Converter Bit Failure
By looking at noise with a 3 s sweep time (push Instrument Preset first), it is possible to
determine which of the data bits are stuck by counting the discrete states displayed. For
example, Figure 4 shows the result of an MSB failure
(D9).
21°vg = 2 states are displayed.
To detect low order bit (DO-D4) failures, tune to the CAL OUTPUT signal and set frequency
span to 100
kHz,
sweep time to 3 s. A failure will then result in slight “stair-stepping” of the
displayed signal. The noise display will be missing states, but this will be difficult to see.
Digital Storage Test Program 4 is used to verify the inputs to the DAC, U5.
lf
VRl
is close to
the low end of its tolerance,
VREF
of DAC U5 may not be properly set.
Failures in the video analog to digital process are characterized by “stair-stepped” signals and
noise that is displayed as discrete vertical lines. Low order bit failures will cause many small
steps while a high order bit failure will cause a single step that will eliminate the peak of the
display. Note that only the signal will be affected and that the graticules and characters will
not be affected. Front panel displays of the CAL OUTPUT signal for several bit failures are
shown in Figures 5 and 6.

If the RAMP, HOLD or BUSY lines become stuck, the display will show a sweep related
problem. If the analyzer is not sweeping, the Sweep System Troubleshooting notes should be
consulted to help isolate the failure to a particular assembly.
Table 1 contains the display symptoms that result from failures of the RAMP, HOLD or

Test Circuit
The test circuit on
A3A8
is designed to aid in troubleshooting lower-order bit failures and
linearity problems in both the Ramp Converter circuit and the ADC circuit. The test circuit
is normally transparent to A3A8 operation, and is activated by grounding
A3A8TP8
NOISE
TEST or A3A8TPlO RAMP TEST to A3A8TP9 to switch
multiplexers
U16, U17, and U18.
Noise Test
The Noise Test, activated by grounding
A3A8TP8
NOISE TEST to
A3A8TP9,
“expands”
the vertical scale of the Digital Storage Section for closer examination of digital data from
the ADC circuit. This is accomplished by shifting the 4 least significant bits (LSBs) of
the digitized video data by 6 bits, effectively multiplying it by 64. When the noise test is
activated, the 6 most significant bits (MSBs) are not used, and the 6
LSBs
are forced to logic
0. In addition, the “new” MSB is inverted to center the CRT trace (assuming the VIDEO
input signal was at top-screen). The resulting CRT trace appears to be amplified to 64 times
the normal resolution allowing variations in the
LSBs
to be easily viewed.
With the noise test activated, a constant VIDEO signal present at the input to A3A9 Track
and Hold will ideally produce a flat CRT trace. The CRT trace should exhibit no more than 2
bits peak-to-peak of digital noise.
Stuck ADC bits and transistor noise on A3A8 can be easily checked in the noise test mode by
removing
A3A9
Track and Hold from the instrument and jumpering
A3A8TP2
SWP/lOO to
A3A8TP6
VIDEO. This substitutes a scaled-down sweep ramp signal for the VIDEO input
signal to the ADC. A series of approximately 10 stair-steps should be displayed on the CRT,
each with sharp, well-defined corners.
The noise test mode can be used to adjust the peak detector offsets (OFS POS and OFS
NEG) on
A3A9
Track and Hold by grounding
A3A9TP3
to
A3A9TP1,
with the VIDEO cable
(96) disconnected from
A3A9Jl.
The CRT trace will fall on the bottom graticule line when
both offsets on
A3A9
are properly adjusted.
Ramp Test
The Ramp test is very similar to the Noise Test, and is activated by grounding
A3A8TPlO
RAMP TEST to A3A8TP9. In addition, the VIDEO cable (96) is disconnected from
A3A9J1,
and
A3A8TPl
SWP is jumpered to
A3A9TP3
to substitute the sweep ramp signal as the
VIDEO input to
A3A9
Track and Hold. In the ramp test mode, the test circuit again
“expands” the vertical CRT scale by a factor of 64. The 4
LSBs
of digital scan data are
subtracted from the 4
LSBs
of digitized video data, and the results are displayed on the CRT.
Since both sets of digital data correspond to the sweep ramp voltage, the subtraction ideally
yields a constant value (011100000=448). If the Track and Hold, ADC, and Ramp Converter
circuits are linear and functioning properly, a horizontal line will appear approximately
1/2division
below the center CRT graticule line. This line might exhibit numerous noise-like
spikes in peak-detector mode, which is normal.
Linearity and noise in the Ramp Converter, ADC, and Track and Hold circuits can also be
checked without using the ramp test. As before, disconnect the VIDEO cable (96) from
A3A9Jl
and jumper
A3A8TPl
SWP to
A3A9TP3.
This substitutes the sweep ramp signal as
the VIDEO input to
A3A9
Track and Hold. A straight diagonal line should be displayed on
the CRT, indicating linear digitizing of the analog sweep ramp signal by both the ADC and
the Ramp Converter circuits.

Track and Hold, Circuit Description
A3A9
Track and Hold provides circuitry to insure that the true peak of the RF signal and a
true representation of noise are displayed on the CRT. This is accomplished by positive and
negative peak detection.
Positive Peak Detector
@
The Positive Peak Detector acquires the most positive voltage to appear at its input and
holds that voltage on holding capacitor C26 until the circuit is reset by a reset pulse from the
decoding and timing circuits. FET Q6 is periodically turned on by the reset pulse, discharging
C26 through R12 and
QS
to ground. Figure 1 shows a simplified schematic of the Positive
Peak Detector.
EOUT
Figure 1. Positive Peak Detector, Simplified Schematic
The circuit consists of amplifier Q3, Q2,
Ql,
diode
CRl,
holding capacitor C26, and buffer
Q4, Q5. When
Ei,
is less than the feedback voltage
E,t,
CR1 is off and C26 will hold the
voltage it has acquired. CR3 limits the reverse voltage across CR1 to minimize leakage
current. CR1 turns on when
Ei,
is greater than E
out’
E
and C26 charges to equalize
Ei,
and
out-
A pair of matched FETs, Q4A and
Q4B,
and emitter follower Q5 are used in the buffer
circuit. Q4A is used as a source follower and
Q4B
as a current source. The Q4A bias current
is equal to the algebraic sum of the current from
Q4B,
the base current to Q3B, and the bias
current through R13. This sum of currents insures a very small gate-to-source voltage and
prevents gate-to-source forward biasing.
Ql,
Q2, and Q3 are all dual transistors. Q3 and Q2 form the input stage, with Q3 connected
as emitter followers and Q2 forming a differential pair. Gain for the differential stage is set by
collector resistor R7. Additional gain is provided by
QlB.
QlB
is connected as a transistor
inverter with
R9
in the emitter and R8 in the collector.
QlA
is connected as a diode. Gain
and offset adjustments for the Positive Peak Detector are performed in the resistor divider
that includes
Rl
and R2. GPOS potentiometer R39 adjusts the attenuation so that a 2 V
full-scale input produces a 1 V full-scale output. OFS POS potentiometer R44 zeroes the
A3A9
1
output with 0 V input. U5 compares the input and output of the Peak Detector. A TTL high
level is produced when the output is greater than the input. (R40, R41, and
R16
provide a
small amount of hysteresis for noise immunity.)
Negative Peak Detector
@
The Negative Peak Detector acquires the most negative voltage to appear at its input and
holds that voltage on holding capacitor C38 until reset by a pulse from the decoding and
timing circuits. Circuit operation is the same as that of the Positive Peak Detector except
that supply polarities are reversed and PNP instead NPN transistors are used. Figure 2 shows
a simplified schematic of the Negative Peak Detector.

FROM
A4A1
R52
Eoul
Figure 2. Negative Peak Detector, Simplified Schematic
The circuit consists of amplifier
Q7/Q8/QlO,
diode CR2, holding capacitor C38, buffer
Qll/Q9,
and reset transistor Q12. R71 creates an offset between the output and the emitter
of
Q9.
This insures that the voltage across C38 is always negative for positive outputs from
0 V to
+1
V. GNEG potentiometer R52 sets the gain (input attenuation) so that a 2 V
full-scale input produces a 1 V full-scale output. OFS NEG potentiometer R36 zeroes the
offset. U4 compares the input to the output.
Decoding and Timing
@
The Decoding and Timing circuit provides reset pulses to the Peak Detectors and control lines
for Multiplexer selection, and it performs other logic functions.
U9
decodes control lines SEL A and SEL B to produce three lines for Multiplexer selection.
After inversion by
U8A,
U8B,
and
U8C,
the voltage levels are shifted to -0.5 V and +9 V.
Multivibrators
U12A
and
U12B
produce pulses (when triggered by HOLD) which reset the
Peak Detectors. Latches U13A and
U13B
are used to provide the Peak Detector status signal
LTRK.
Multiplexer
@
The outputs of the Peak Detectors are multiplexed through
Ul
before sampling by the Track
and Hold circuit. Control lines to the Multiplexer are provided by the Decoding and Timing
circuit.

A3A9
Track and Hold
@
The Track and Hold circuit samples the signal appearing at the output of multiplexer
Ul
and
holds the voltage on capacitor
(215.
The output of the Track and Hold circuit is used in A3A8
Analog-Digital Converter, where it is converted into Y-axis graph data. A simplified schematic
of the Track and Hold circuit is shown in Figure 3.

A3A8
Figure 3. Track and Hold Circuit, Simplified Schematic
Ql6
and Q15 form a buffer amplifier.
Q14
switches on and off to open or close a path between
the amplifier and holding capacitor C15. A FET input amplifier (Q13, US) amplifies the
capacitor voltage by a factor of 10. The gain is set the T/H GAIN potentiometer R57. Offset
is adjusted by controlling the current flow through R67 with (T/H) OFS potentiometer R59.

A3A9 Track and Hold, Troubleshooting
Display problems which involve only the video are often caused by malfunctions on either
A3A8 Analog-Digital Converter or the A3A9 Track and Hold. The blue
[SHIFT]
key functions
and the Digital Storage Test Patterns can be used to isolate the failure.
Figure 4 shows the Digital Storage Test Pattern. Refer to “A3 Digital Storage
Troubleshooting” to generate the test pattern. The three vertical lines represent the detector
outputs on
A3A9.
The left one is the negative peak detector, the center one is the sampling
mode and the right one is the positive peak detector. These should move up and down when
a VIDEO signal is present at A3A9J1, indicating normal operation. If one is stuck, the blue
(SHIFT) key can be used to verify this.

Figure 4. Typical Digital Storage Test Pattern
Slight stair-stepping of the diagonal line could be caused by a low order bit failure on
A3A8
or a noisy component on A3A9. To isolate the assemblies remove
A3A9,
jumper
A3A8TPl
to
A3A8TP6
and push Instrument Preset. The Display is a diagonal line. If the diagonal line is
not stair-stepped or noisy, the problem is on A3A9.
Noise on the peaks of the displayed signals is most often caused by leakage in
QS
or Q14. This
is very noticeable in 0 Hz frequency spans. To determine whether Q6 or
Q14

sampling detection is used. (SHIFT) TRACE A
(BLANK]
(KSe) puts the instrument in the
sampling mode. A noisy signal when using the sampling mode generally indicates a defective
Q14. A defective
QS
produces noise in the normal detection mode and in the positive peak
detection mode,

If the traces do not coincide in the above test, refer to “Track and Hold Adjustments” in the
Performance Tests and Adjustments Manual.
If the voltage on
A3A9TP8
is correct and that of
A3A9TP9
is incorrect when performing the
BIAS Check of Note 10 on the schematic, check to see if the drain and source voltages on
Q14
are approximately
+l
V. If not, Q14 is most likely open.
The LTRK signal is verified using an oscilloscope. Following an Instrument Preset, set the
spectrum analyzer sweep time to 75 ms. Figure 5 shows the resultant waveform.
Oscilloscope settings:
Sweeptime: 50
ms/div
Anolyzer Sweeptime: 75 ms

The Decoding and Timing

is checked using an oscilloscope. Figure 6 shows the timing
waveforms when using Digital Storage Test Program 5. When Digital Storage Test Program
6 is used, HOLD is normally high. It goes low every 80 ms. The two reset lines are then
active only every 80 ms. Figure 5 shows the LTRK line for a sweep time of 75 ms following an
Instrument Preset.

For Test Program 6, HOLD is normally high, going low only every 80
msec
which resets
the peak detectors (RESET POS.PK and RESET NEG.PK). All other
wave
forms remain the
same
as for Test Program 5.

Video Processor, Circuit Description
A4Al
Video Processor filters the detected IF signal from
A4A2
Log Amplifier, it sets the
dB/DIV
LOG SCALE and the REFERENCE LEVEL offsets below -50
dBm
or -70
dBm,
and it provides the IF video output and the X and Y recorder outputs.
Video Filter
@
The Video Filter is an RC low pass filter with selectable R and C. The series resistance R
is one of two values controlled by switch U7. When the switch is closed (0),
R17
is short
circuited and the series resistance is minimum. In this state, video bandwidths from 3
kHz
to
3 MHz are attainable (The 3 MHz nominal bandwidth is attained when Q14 through Q20 are
turned off). When switch U7 is open
(l),
the series resistance R is high, approximately equal
to R17 and video bandwidths from 1 Hz to 1
kHz
are attainable. Shunt capacitors C5 through
Cl1
are selected by switching transistors Q14 through Q20. Only one of these switching
transistors can be on at any one time. Each capacitor except
Cl1
is used with the high series
resistance for the lower bandwidths and the low series resistance for the higher bandwidths.
Log Expand
@
The Log Expand circuit allows four different amplitude scales:
10,5,2,
1
dB/DIV.
Changes
in the amplitude scale are accomplished by first amplifying the video signal, then attenuating
it various amounts. This is accomplished by FET input amplifier U2, which offsets the input
-5 V and whose gain (set by R22 and R21) is 5. The offset is set by the current through
Ql.
This current source is adjustable using OS potentiometer R14. Switching transistors Q4, Q5,
and Q6 are turned on or off to achieve voltage divider ratios of
l/10,
l/5,
l/2,
and 1. Diodes
CR2 and CR3 clamp this attenuated signal at about -1.2 V to prevent forward biasing
any switch in the off state. A final amplifier consisting of Q7,
QS,
and
Q9
amplifies this
attenuated signal by 4 and offsets the output
+2
V. A
+2
V output corresponds to a full-scale
signal. This final amplifier is a two-stage amplifier. The first stage is a FET input stage made
up of dual FET Q7. The first-stage output is multiplied by the transistor inverter
QS,
whose
output is buffered by an emitter follower
Q9.
This output is fed back to the inverting input
through a resistor divider stick. Gain of the amplifier is adjusted by ZERO potentiometer
R32, and offset for full scale is adjusted by FS potentiometer R36. Diode CR1 clamps the
output at about -1.2 V.
A4Al 1
Log Offset Current Source
@
The Log Offset Current Source simulates log gain for instrument reference levels below
-60 dBm. This is achieved by offsetting the 0 V to 1 V video input signal by driving current
through the source resistance R16. This current is changed by supplying different currents
into the emitter of Q13, the transistor current source. Currents are controlled by switching
transistors
&lo,
Qll,
and Q12. For example, when switch Q12 is turned on, the transistor
saturates and a current flows through R5 into the emitter of Q13. This emitter current (set by
the voltage drop across R5) is closely equal to the collector current through Q12. The voltage
drop across R5 can be changed by varying LG OS potentiometer R2, since U6 pin 3 and the
emitter of
Q13
are at the same voltage. This is true because U6 is a voltage follower with
unity gain. Once R2 is set, the accuracy of R5, R7, and
R9
determines the relative accuracy
of the offsets, 0.1 V, 0.2 V, 0.2 V (10
dB,
20
dB,
20
dB).
Power Supplies
@
Zener
diode VR2 is used to provide the -8.8 V supply, which is used in the Log Expand
circuit with the FS adjustment R36.
Decode Logic
@J
The Decode Logic circuit performs additional decoding on output lines from IF Control A4A9.
VBWA, VBWB, VBWC, and VBWD are decoded by U8, a l-of-8 decoder, and inverted by
UlO
to drive one of the seven capacitors used in the Video Filter.
Ull
decodes A LOG and B
LOG and drives the switches that vary the attenuator in the Log Expand circuit.
Recorder Output
@
The Recorder Output circuit provides outputs for an X-Y plotter. Also provided are outputs
for calibrating lower left (LL) and upper right (UR). Calibration outputs and signal outputs
are routed through switch U4. A control line, REC CAL, from IF Control A4A9 controls the
state of the U4 switches. When REC CAL is high, the video output through U3 and AUX
SWEEP have closed paths through the switch to provide VIDEO and SWEEP outputs to the
rear panel. When the REC CAL is low, a closed path through the switch exists between the
calibration voltages and the VIDEO and SWEEP outputs. Control line REC ZERO causes
the FS or ZERO voltage to appear across the R50, R55,
R51
divider stick. When in LL, REC
ZERO is low and the switch inputs are pulled to about 0 V. When REC ZERO is high, its
open collector output will be set to the voltage determined by the divider stick:
+lO
V for
X,
out, and +1 V for
Y,
out.

A4A2
Log Amplifier-Detector, Circuit Description
A4A2
Log Amplifier-Detector Assembly contains the last four of the nine log amplifier stages.
(The first five stages are in
A483
Log Amplifier-Filter.) The first two stages in this assembly
(Stage 6 and Stage 7) are also used in linear mode as a switchable 20
dB
gain step. Following
the last log stage, the 21.4 MHz IF signal is applied to a PIN diode attenuator. In log mode,
this attenuation is varied with temperature to compensate for bias variations in the log stages.
After passing through the PIN attenuator, the IF signal is detected to produce the vertical
(video) signal which is applied to
A4Al
Video Processor. The 21.4 MHz signal is attenuated
and sent to the 21.4 MHz IF OUTPUT connector on the rear panel.
The control circuit of
A4A2
contains log/linear switching circuitry and 20
dB
linear gain
step switching circuitry. Also contained in A4A2 is a temperature-dependent power supply
which biases the log stages in A4A2 and A4A3. A similar temperature-dependent bias supply
controls the attenuation of the PIN Diode Attenuator.
Log Amplifier Stages
@
A4A2
contains the last four of the nine log amplifier stages. (Refer to A4A3 Log
Amplifier-Filter for a description of log amplifier stages.) The operation of each stage is
essentially identical to that of the log stages in A4A3.
LOG Mode
In LOG mode, the LOG/LIN control line from A4A9 IF Control is high (about
+7
V).
Q9
is turned on, connecting the log diode bias resistor of each stage to the -12 VTV supply
through CR16 and CR18.
QS
is off and PIN diodes CR12 and CR15 are reverse biased
through R50. The LG20 control line from A4A9 IF Control Assembly is low in LOG mode,
so
QlO
is off and CR6 and CR9 are reverse biased. Thus all log diodes are on, and linear gain
PIN diodes are off. The logged IF signal is applied through Q14 to the PIN Diode Attenuator,
the Detector, and the Counter Output Limiter.
LINEAR Mode
Each of the log stages in this assembly provides linear gain through the use of a switchable
PIN diode signal path. In LINEAR mode, the LOG/LIN control line is pulled to the -12
VTV supply through
RlOl.
This turns off
Q9,
removing the bias current from all log diodes.
As the
Q9
collector is pulled high through R46, the
QS
collector saturates to the -12 VTV
supply, forward biasing PIN diodes CR2 and CR15 through CR21 in Log Amplifier Stages
8 and 9. Since PIN diode resistance is not affected by signal level, Stages 8 and 9 become
non-limiting amplifiers with combined gain of approximately 15
dB.
R36 is factory selected
to adjust the gain of Stage 9 in LINEAR mode. This gain is necessary to obtain a 1 V (full
screen) video output in linear mode at approximately the same input level to the IF module
that causes a 1 V (full screen) output in LOG mode.
A4A2
1
20
dB
Linear Gain Step
Stages 6 and 7 are used as a switchable 20
dB
gain step in LINEAR mode at low reference
levels. When the LG20 control line is high (more positive than -5 V), the
QlO
collector
saturates to the -12 VTV supply, turning on PIN diodes CR6 and CR9 in Log Amplifier
Stages 6 and 7. Stage 6 and 7 each provide approximately 10
dB
of non-limiting gain when
LG20 is high. The combined gain of stages 6 and 7 is adjusted to 20
dB
by varying the
resistance of CR6. R14 sets the bias current and thus the resistance of CR6.
Pin Diode Attenuator
(Q
In LOG mode, attenuation of the PIN Diode Attenuator is varied with temperature to
compensate for bias variations with temperature in the Log Amplifier Stages. The attenuation
is removed in the LINEAR mode.
LOG Mode
In LOG mode, Q7 is turned off because
QS
is off. CR30 is forward biased by the LOG/LIN
control line through R63. PIN diodes CR28 and CR29 are forward biased by
UlB
through
R62 and R61. PIN diodes CR26 and CR27 operate with fixed bias current through R56 and
R57. CR26 through CR29 form a resistive voltage divider with CR28 and CR29 operating as
a variable resistance. Op amp
Ul,
which biases CR28 and CR29, is a temperature dependent
voltage source. The voltage at
Ul
pin 7 becomes more negative as temperature increases,
causing the attenuation to increase. The attenuation of the PIN Diode Attenuator is set by
R61 (refer to ATTEN and -12 VTV Adjustments).
LINEAR Mode
In LINEAR mode,
Q90
is off and
QS
and Q7 are on. Q7 supplies additional drive for CR26
and CR27 through R58. This biases CR26 and CR27 so that their resistance is small
(<50R
total). CR28 and CR29 are reverse biased through R63, since LOG/LIN is pulled to -12
VTV in linear mode. There is no attenuation, and the signal from Q14 is coupled directly to
emitter follower Q5.
Detector Driver
The signal output from the PIN Diode attenuator is applied to emitter follower Q5, which
provides low-impedance drive for the Detector. Bias for Q5 is supplied by R65, which with
R64 forms a voltage divider for the signal from the Q5 emitter. The signal at
Jl
is linearly
related to the displayed vertical signal in both LINEAR and LOG modes. The signal is sent
by coax cable to the 21.4 MHz IF OUTPUT connector on the rear panel.
Temperature-Dependent Regulators
@
The -12 VTV and PIN Diode Regulators provide temperature compensation for the Log
Amplifier Stages. CR37 and CR38 operate as the temperature sensing elements to control
the two voltages.
UlA
controls
Qll
to regulate the -12 VTV supply, which provides a
nominal -12 V to a
filter
network for distribution throughout the Log Amplifier assemblies.
The -12 VTV voltage is adjusted to provide proper log fidelity; it becomes more negative
as temperature increases to correct for variations in log diode resistance.
UlB
produces a
nominal -7 V and forms the current source for CR28 and CR29 in the PIN Diode Attenuator.
The voltage of
UlB
pin 7 becomes more negative as temperature increases to control the
attenuation of the PIN Diode Attenuator.

A4A2
ATTEN
@
and -12
VlV
Adjustments
@I
The PIN Diode Attenuator adjustment
(ATTEN
potentiometer R61) is essentially a gain
adjustment that varies the slope of the log curve. The -12 VTV adjustment (-12 VTV
potentiometer
R91
in the Temperature-Dependent Regulators circuit) varies the offset and
slope of the log curve. These two adjustments (which interact) are used to set the output
versus input curve in log mode. The IF input signal level, which causes a 1 V (full screen)
output in LINEAR mode, is used as a reference for full-scale deflection in LOG mode. The
ATTEN
and -12 VTV adjustments are made to give a 1 V video output in both LOG and
LINEAR modes for the same IF input signal level, and a 100
mV
video output change for a 10
dB
IF signal change in LOG mode.
Detector
@
Ql through Q4 d
an
associated circuitry form a full wave rectifier to convert the IF signal to
a video signal. Q4 is the current driver for the detector and converts voltage variations at
the Q5 emitter to current variations which drive Q2 and Q3. Q3 is a half wave rectifier and
conducts when the signal at the Q5 emitter is positive. The Q3 collector current is applied to
the low-pass filter consisting of R75, R76,
L12
through L14, and C51 through C54. When the
signal at the Q5 collector goes negative, current generated in the Q4 collector is pulled out of
the Q2 emitter.
Ql
forms a current mirror, which drives current into the low-pass filter when
Q2 collector current flows. Thus current flows into the low-pass filter on both positive and
negative halves of the IF signal at the Q5 emitter. CR31, CR32, CR33, and R72 keep Q2 and
Q3 biased slightly below cutoff. When current flows into the low-pass filter from
Ql
or Q3, a
positive voltage is developed across R75 and R76. The voltage developed is proportional to
the IF signal level at the Q5 emitter. The low-pass filter has a bandwidth of about 7 MHz to
remove IF frequencies from the detected video output signal. The detected voltage is applied
to unity gain buffer amplifier Q12 and
Q13
to drive
A4Al
Video Processor. The offset of
differential pair
Q12
is removed by ZERO adjustment R79.
Counter Output Limiter
@
The Counter Output Limiter provides an amplitude-limited signal at the IF frequency used
for frequency counting. The IF signal from detector driver Q5 is buffered by
QS.
CR35 and
CR36 are biased to cutoff for signal levels corresponding to greater than a one-division display.
In LOG or LINEAR mode, the counter output remains at approximately -30
dBm
for signal
levels displayed in the top nine divisions of the display.

A4A2 Log Amplifier-Detector, Troubleshooting
If the amplitude of the displayed signals is approximately 10
dB
low (CAL OUTPUT appears
to be -20
dBm)
in the log mode but correct in the linear display mode, then one of the log
amplifier stages in the
A4A3
Log Amplifier-Filter board or the
A4A2
Log Amplifier-Detector
board is defective. Connect a 10
dB
step attenuator between the CAL OUTPUT and the
spectrum analyzer input. Refer to the Log Amplifier Stage Gain Check note on the service
sheets for the necessary front-panel control settings. When forward biased in log mode, the
Schottky diodes should have voltage drops of 200 to 400 mV.
The following procedure will determine if the Linear Gain Steps, LGlO and LG20, are
operating properly. The LGlO circuitry is located on the A4A3 Log Amplifier-Filter board
while the LG20 circuitry is located on the A4A2 Log Amplifier-Detector board. Connect a
10
dB
step attenuator set to 0
dB
between the CAL OUTPUT and the spectrum analyzer
input. Press Instrument Preset and key in the following settings:

The peak of the displayed signal should be on the top graticule. Adjust the front panel
AMPTD CAL control to place the peak of the signal one division below the top graticule.
If the signal limits at the top of the display, one of the Linear Gain Steps is stuck in the on
state.
Set the 10
dB
step attenuator to 10
dB
and key in (REFERENCE LEVEL) -70
dBm.
The peak
of the displayed signal should be one division below the top graticule. If signal limits at the
top of the display, the LG20 circuitry is defective. A signal approximately 3 divisions high
indicates the LGlO circuitry is defective.
Set the 10
dB
step attenuator to 20
dB
and key in (REFERENCE LEVEL) -80
dBm.
The peak
of the displayed signal should be one division below the top graticule. The LGlO circuitry
is defective if the signal limits at the top of the display. The LG20 circuitry is faulty if the
displayed signal is approximately 3 divisions high.
The detector circuit on the A4A2 Log Amplifier-Detector board is most easily checked with
dc voltages. These are derived using 0 Hz (CENTER FREQUENCY) and attenuating the CAL
OUTPUT signal. The easiest point to check the Detector output without removing boards is
A4AlTPl.
Connect a DVM to this test point. The voltage at
A4AlTPl
should be
+l
V for
a signal displayed on the top graticule. The output will be 0.1 V less for each division down
from the top in either the linear or the 10
dB/DIV
log modes when the detector is operating
properly.

A4A3
A4A3 Log Amplifier-Filter, Circuit Description
A4A3 Log Amplifier-Filter, with
A4A2
Log Amplifier-Detector, provides the ability to display
signals in either a linear or log mode. In log mode the calibrated display range is 90
dB.
A4A3
contains the first five of nine log stages, and
A4A2
contains the last four. A4A3 also contains
circuitry for using one of the log stages as a switchable 10
dB
gain step. This is used only in
linear mode.
After being processed by the first five log amplifier stages, the 21.4 MHz IF signal is applied
to the log amplifier filter, the bandwidth of which is either narrow (approximately 1 MHz)
or wide
(>20
MHz). The filter is in narrow mode for resolution bandwidths of
130
kHz
to
reduce noise generated in the log amplifier stages.
Control lines from A4A9 IF Control drive circuits of
A4A3
which control the log amplifier
filter, log/linear switching, and 10
dB
linear gain step.
Log Amplifier Stages
@
In LOG mode, the five log amplifier stages in A4A3 and the four log amplifier stages in
A4A2
limit their gain in sequence with increasing signal level to provide 90
dB
of log display range.
In LINEAR mode, signal-level-dependent components are switched out of the signal path, and
a
linear display is provided.
LOG Mode
A simplified schematic of a log amplifier stage is shown in Figure 1. In LOG mode, the
LOG/LIN control line is high (about
+7
V),
Ql6
is on, forward biasing log diodes CR25,
CR26, and all other log diodes in this assembly. CR25 and CR26 are Schottky diodes
with a forward bias voltage of approximately
+0.4
V.
Qll
is an emitter follower used as a
voltage source which drives Q12 through the resistance of CR25 and CR26. Q12 forms a
common-base amplifier tuned to approximately 21.4 MHz. The gain of the amplifier is set by
the ratio of R48 to the total resistance
RT
between the emitters of
Qll
and Q12 (primarily
the resistance of CR25 and CR26). The formula for computing gain is:
G=l+g
RT
is at a minimum (approximately 150
a)
for small signals. The small-signal gain of the
stage (about 10 dB) is set by the dc bias current through the log diodes. As the signal level
at the
Qll
emitter increases, signal current cancels bias current in the log diodes, increasing
RT.
The gain of the stage for large signals is reduced to nearly unity (0 dB) because
RT
becomes very large. Signal current flow through R49 keeps the stage gain slightly above unity
to compensate for the input loading of the following stage.
A4A3
1
Bias Supplies
The -12 VTV is supplied to
A4A3
from A4A2. This voltage determines log diode bias
current and becomes more negative as temperature increases to compensate for the increased
resistance of the log diodes. The same supply is used to compensate the log diodes of the four
log stages in
A4A2.
LINEAR Mode
In LINEAR Mode (See Figure 1) log diodes CR15 and CR16 are zero biased, and the limiting
action is removed from the stage.
RT
is large, and stage gain is nearly unity. Signal flow is
through emitter follower
Qll
and R48 to Q13.

Figure 1. Log Amplifier Stage, Simplified Schematic
Log Stages
All nine of the log amplifier stages in
A4A2
and A4A3 are similar in operation, although
there are variations in certain stages. While all stages except the first three contain two log
diodes each, the first two stages contain six diodes each, and the third contains four diodes.
More diodes are used in Stages 1 through 3 because these stages have their logging action at
higher signal levels than the other log stages. Log diodes of Stages 1 and 2 are biased so that
the logging action occurs at signal levels of approximately 0 dBm to $10 dBm, whereas the
remaining stages log at lower signal levels. To provide proper log fidelity (log amplifier output
versus input), attenuation is required between the output of a higher level log stage and the
input of a lower level log stage. Resistive divider R20, R29, and R30 attenuates the output of
Stage 2, and a similar attenuator is used between Stages 3 and 4. Resistors in series with the
log diodes of Stage 1 through 3 are factory-selected to compensate for variations in log diode
resistance. Correct stage gain is required for proper log fidelity. Refer to the A4A3 schematic
note for the method of checking the gain of Stages 1 through 5 in log mode.
2
A4A3
10
dB
Linear Gain Step
Stage 5 is used as a switchable 10
dB
gain step in linear mode at low reference levels. When
control line LGlO is low (-12 V typical), Q17 is off and CR27 is reverse biased, preventing
CR27 from being a signal path. When control line
LGlO
is high (more positive than -3 V),
the Q17 collector is saturated to the -12 VTV supply, and PIN diode CR27 is forward biased.
LGlO adjustment R83 sets the bias current (and thus resistance) of PIN diode CR27. The
resistance of CR27 plus R54 is set so that the gain of Stage 5 will increase by 10
dB
when
CR27 is turned on. (Refer to the foregoing gain formula.) Since PIN diode resistance is
unaffected by signal level, Stage 5 operates as a non-limiting amplifier. This 10
dB
gain step,
in conjunction with a similar 20
dB
gain step in
A4A2,
is used for the last 30
dB
of step gain
(lowest 30
dB
of reference level) in linear mode. See the schematic note for the reference levels
at which this gain step is checked.
Bandpass
Filters
@
In narrow resolution bandwidths, noise generated in the log amplifiers is reduced by the
Bandpass
Filter following Log Amplifier Stage 5. The bandwidth of this filter is switchable
between wide
(>20
MHz) and narrow (about 1 MHz). In resolution bandwidths of 30
kHz
or less, the filter bandwidth is narrow. This reduces the log amplifier noise contribution 90
dB
down from the reference level. In resolution bandwidths of 100
kHz
and greater, the
bandwidth of the filter is wide enough so as not to affect the shape of the wide resolution
bandwidth filters. (See Figure 2.)

Figure 2. Bandpass Filter, Simplified Schematic
Bandpass Filter Switching
Emitter follower Q13 buffers the output of Log Amplifier Stage 5 and drives the
Bandpass
Filter. The filter bandwidth is determined by the resistance through which the LC tank
network (L14 and C52 through C55) is driven. In resolution bandwidths of 3 MHz to 100
kHz,
bandwidth control line BW5 is high
(+15
V) and CR30 is forward biased through R63,
resulting in a low filter drive impedance and wide bandwidth. When the analyzer resolution
A4A3
3
bandwidth is less than 100
kHz,
BW5 is low (about -0.6 V). CR30 is reverse biased, and
the LC shunt network is driven through R62, setting the filter bandwidth at about 1 MHz.
The signal is buffered by
Q14
and Q15. The output of buffer amplifier Q14/Q15 provides
a low impedance drive for the Low-Pass Filter. The Buffer Amplifier
Q14/Q15
also drives
the center tap of L14 through the resistance of PIN diodes CR28 and CR29. This feedback
results in an apparent negative input resistance in parallel with L14. The negative input
resistance compensates for the parallel resistance present in the tank circuit because of the Q
of L14. The gain of the filter in narrow mode is set equal to that in wide mode by setting
the resistance CR28 and CR29. The resistance of CR28 and CR29 is set by adjusting the
diode bias current with FILTER AMPTD adjustment R67. L13 and C39 are frequency
compensation for Q14 and Q15.
BW5 Input Section
TP7 and TP8 provide a means to adjust the
bandpass
filter for equal gain in wide and
narrow modes. This can be done without changing IF bandwidth, which might in itself
introduce an amplitude change. With the analyzer in narrow resolution bandwidths (30
kHz
through 10 Hz), BW5 is approximately -0.6 V, which reverse biases CR30. This places the
Bandpass
Filter in narrow mode. The center frequency of the
bandpass
filter can be adjusted
with CTR adjustment C55. To place the
Bandpass
Filter in wide mode, TP7 and TP8 are
shorted together with a jumper wire. This forward biases CR30 through R89 and R63. Filter
amplitude can then be set with FILTER AMPTD adjustment R67 so that amplitudes are
equal in wide (test points jumpered) and narrow (jumper removed) modes.
Filter Temperature Compensation
@
The Filter Temperature Compensation circuit stabilizes the gain of the
bandpass
filter with
temperature changes.
Op Amp
Ul
and associated circuitry provide temperature dependent bias for CR28 and CR29
to compensate for temperature-dependent change in the Q of L14 and the resistance of CR28
and CR29. As temperature increases, diode bias current increases as the voltage at
Ul
pin 6
increases. CR5 and CR6 operate as temperature-sensing elements to control the voltage at
Ul
pin 6.
Low-Pass Filter
@
The Low-Pass Filter consists of
L15,
L16, C56 through C59, R67, and R68. It has a
bandwidth of about 30 MHz, which removes harmonics of the 21.4
HMz
IF signal to reduce
log fidelity variations between wide and narrow settings of the
Bandpass
Filter. The Low-Pass
Filter has a loss of 6 dB, which is compensated for by buffer amplifier
QlS/Ql9,
which has a
gain of 6
dB.
R74*
is factory-selected to adjust the gain of
QlS/Ql9
for proper log fidelity.

Amplifier-Filter,
Troubleshooting
If the amplitude of the displayed signals is approximately 10
dB
low (CAL OUTPUT appears
to be -20 dBm) in the log mode but correct in the linear display mode, then one of the log
amplifier stages in the A4A3 Log Amplifier-Filter board or the A4A2 Log Amplifier-Detector
board is defective. Connect. a 10
dB
step attenuator between the CAL OUTPUT and the
spectrum analyzer input. Refer to the Log Amplifier Stage Gain Check note on the service
sheets for the necessary front-panel control settings. When forward biased in log mode,
the
Schottky diodes should have voltage drops of 200 to 400
mV.
The following procedure will determine if the Linear Gain Steps,
LGlO
and LG20, are
operating properly. The LGlO circuitry is located on the A4A3 Log Amplifier-Filter board
while the LG20 circuitry is located on the A4A2 Log Amplifier-Detector board. Connect a
10
dB
step attenuator set to 0
dB
between the CAL OUTPUT and the spectrum analyzer
input. Press Instrument Preset and key in the following settings:

The peak of the displayed signal should be on the top graticule. Adjust the front panel
AMPTD CAL control to place the peak of the signal one division below the top graticule.
If the signal limits at the top of the display, one of the Linear Gain Steps is stuck in the on
state.
Set the 10
dB
step attenuator to 10
dB
and key in [REFERENCE LEVEL) -70
dBm.
The peak
of the displayed signal should be one division below the top graticule. If signal limits at, the
top of the display, the LG20 circuitry is defective. A signal approximately 3 divisions high
indicates the LGlO circuitry is defective.
Set the 10
dB
step attenuator to 20
dB
and key in
[REFERENCE
LEVEL] -80
dBm.
The peak
of the displayed signal should be one division below the top graticule. The
LGlO
circuitry
is defective if the signal limits at the top of the display. The LG20 circuitry is faulty if the
displayed signal is approximately 3 divisions high.
The detector circuit. on the A4A2 Log Amplifier-Detector board is
most
easily checked with dc
voltages. These are derived using 0 Hz
[FREQUENCY

and attenuating the CAL OUTPUT
signal. The easiest point to check the Detector output without removing boards is
A4AlTPl.
Connect a DVM to this test point. The voltage at
A4AlTPl
should be
+l
V for a signal
displayed on the top graticule. The output will be 0.1 V less for each division down from the
top in either the linear or the 10
dB/DIV
log modes when the detector is operating properly.

Description
A4A4
Bandwidth Filter determines the bandwidth of the 21.4 MHz IF in conjunction with
A4A8 Attenuator-Bandwidth Filter.
A4A4
is very similar to A4A8 except that it does not
have a switchable gain input amplifier, and it has an extra stage of crystal filtering. Only
the 10
dB
Gain Input Buffer Amplifier will be described here. For descriptions of the other
circuits in
A4A4,
refer to descriptions of the corresponding circuits in A4A8.
Input Buffer Amplifier
@
The 10
dB
Input Buffer Amplifier (Figure 1) functions as a noninverting op amp.
Q8.014
Figure 1. A4A4 Input Buffer Amplifier, Equivalent Circuit
In the crystal mode (30
kHz,
10
kHz,
and 3
kHz
bandwidths), the amplifier includes Q7. The
biasing of the amplifier is independent of its RF (21.4 MHz) operation but is very critical for
its proper functioning. If a malfunction occurs, the dc bias should be checked first.
The current through Q14 is determined by the difference between two current sources, one
involving Q7 and the other involving
QS.
(See Figure 2.) The most convenient way to find
the current from each source is to measure the voltage across each emitter resistor (A 1
kS1
resistor should be used in series with the voltmeter probe tip to prevent the circuit from
oscillating and giving an erroneous reading). For Q7, the current through
R90
must be
included. If results are inconsistent, the emitter resistor should be checked also. Check to see
that the BW5 line is at the voltage specified on the schematic.
In the LC mode (the four wider bandwidths), the BW5 line goes to approximately +14.8 V
and turns off the current source Q7. The current supplied by Q7 in the crystal mode is now
supplied through CR1 and R12 from the BW5 line. In the LC mode, the current through Q14
can be found by subtracting the current through R12 from the current through R4.

Step
Gain,
Circuit
Description
A4A5
Step Gain has three functions. It provides 65.9
dB
of gain in discrete 0.1
dB
steps
(from -15.9
dB
to +50
dB);
it
d
evelops
a nominal
+lO
V bias supply; and it provides the
18.4 MHz LO frequency to
A4A6Al
Up Converter and A4A6A2 Down Converter.
Step Gain 10
dB
+ Calibration
@
This circuit is configured as a non-inverting operational amplifier. It provides a minimum of
about 2
dB
gain (adjustable by CAL potentiometer R33) and a maximum of about
12
dB
(adjustable by 10
dB
potentiometer R32).
(S
ee
1
F’g
ure 1.) The PIN diode CR5 functions as a
variable resistor that has about 1 K resistance at minimum and
700
of resistance at maximum
gain. When the
SGlO
line
is not sinking current (SGlO is off), the PIN resistance is controlled
only by R33. When the
SGlO
line is grounded (SGlO is on), the gain is controlled primarily
by R32. If the CAL potentiometer is adjusted, R32 must be adjusted also.

@
This circuit is similar to the Step Gain 10
dB
+ Calibration circuit, except that the gain
range is from 0
dB
to 20
dB.
PIN diode CR6 functions as both a switch and as a variable
resistor. When the
SG20-1
line
is low, CR6 is turned on by current adjustable by 20
dB-1
potentiometer R44. More current through the PIN causes the PIN to have a lower resistance
and the amplifier to have more gain. The Step Gain 20
dB-2
circuit is identical in operation
to the Step Gain 20
dB-1
circuit.

AO.O-AS.9
dB
Attenuators
@
These attenuators normally operate over the range of 0.0
dB
to 9.9
dB
except in the Error
Correction function
(SHIFT)
(FREQUENCY
SPAN),
when they operate over the whole range of
0.0
dB
to 15.9
dB.
The first three attenuation stages, A8dB,
A4dB,
and A2dB, are emitter
followers with a resistor divider on the output of each one. The dividers are switched in
and out with diodes CR8, CR9, and CR10 to yield discrete steps of attenuation. The last
attenuator is variable. Its range is adjusted by VR potentiometer R51. R51 sets the emitter
voltage of
&IS,
which in turn determines how much current is sunk through PIN diode
CR11
when resistors are switched in A4A9 IF Control. (See Figure 2.)

A4A5
+lO V Temperature Compensating Power Supply
@
This supply compensates for the effect of temperature on PIN diodes used on the
A4A5,
A4A4, and
A4A8
assemblies. (See Figure 3.) Its nominal voltage is
+lO
V and its nominal
temperature coefficient is
+35
mV/OC. The output voltage is derived from the following
equation:
vo
=vlz4+vfb
=
(ha)(%)
+
vfi
=
(*)(%,+vfb
=
[
,V’yp-q
(h)
+
Vfi
where:
Vn,
=
3 V (the voltage applied across CR2,
CR3,
CR4, and
R5
at Ul pin 2) and is equal to
the input voltage.
Using circuit values:
FZS
@&$
(51.1K)+3V
[
1
B
9.75v
As temperature changes, the voltage drop across CR2, CR3, and CR4 changes.
This results
in a change in the current through the feedback resistor R4. Since
VOut
=
Vh
+
VR~,
the
voltage developed across R4 changes the output of the supply. The change in
VOut
is directly
proportional to the change in current through R4.

18.4 MHz Oscillator
@
The 18.4 MHz Oscillator is basically a Colpitts oscillator with a crystal
Yl
in the feedback
path. A simplified schematic is shown in Figure 4.
Figure 4. 18.4 MHz Oscillator, Equivalent Circuit
If the crystal were replaced with a large capacitor, the circuit would oscillate at the resonant
frequency of the parallel resonant circuit made up of
Ll,
C13, C14, and C15. When the
crystal is inserted, the feedback path is broken except at the series resonance of the crystal
(18.4 MHz). The parallel combination of varactor
CRl,
temperature-compensating capacitor
C7, and FREQ ZERO COARSE air-variable capacitor Cl0 are in series with the crystal and
can pull it several
kHz
either side of 18.4 MHz.
The voltage output is determined by the current through
RlO*
times the collector load. If the
output is too low, RlO* can be decreased in size.
The collector voltage is divided by C13, C14, and Cl5 and goes to the Buffer Amplifiers. The
division ratio is:
dz
&+&+k
x
0.13
Buffer Amplifiers
@J
The Buffer Amplifiers are two almost identical amplifier circuits. The top amplifier on the
schematic (QlO,
QS)
provides the 18.4 MHz LO signal to
A4A6Al
Up Converter, while the
bottom amplifier (Q12, Q13) provides the signal to
A4A6A2
Down Converter.

Step Gain Test
Often several steps will appear to be slightly in error. Analysis of the truth table
(A4A9
Tables 1 and 2) will indicate that no single stage could be faulty. This is caused by log fidelity
error in the log amplifier circuitry. If accurate determination of the step size is necessary, IF
substitution using a calibrated 1
dB
step attenuator will be required.
Operation of the AVdB control line and the 0.1 to 1.9

Up
Converter,
Circuit
Description
For narrow
(51
kHz)
bandwidths,
A4A6Al
Up Converter Assembly converts the 3 MHz IF
signal from A4A7 3 MHz Filter to a 21.4 MHz IF signal and sends it to
A4A5
Step Gain. For
wide
(23
kHz)
bandwidths, the 21.4 MHz from
A4A6A2
Down Converter is amplified and
sent to A4A5.
Variable Gain Amplifier
@
The Variable Gain Amplifier has about 6
dB
of gain to compensate for the loss incurred by
the 50 Ohm Driver in
A4A6A2,
which converts the 21.4 MHz IF signal into a 50 Ohm system.
21.4 MHz IF Switch
@
For wide
(23
kHz)
bandwidths, the SWITCH line goes to +15 V, which turns
QS
off. This
forward biases CR3 (the current is sunk through the LO Driver and Buffer Amplifier) and
reverse biases CR2, allowing the 21.4 MHz IF signal to pass through CR3 and then to A4A5.
For narrow
(51
kHz)
bandwidths, the SWITCH line goes to 1 V, turning
QS
on. The
collector of
QS
goes to about
+15
V, which turns the LO Driver on, forward biases CR2, and
reverse biases CR3, breaking the path from the Variable Gain Amplifier.
LO Driver and Buffer Amplifier
@
This circuit is only on for bandwidths
_<l
kHz.
It consists of an emitter follower (Q7) driving
a common base stage (Q8) which in turn drives a common emitter stage
(Q9).
The voltages
and signal levels are indicated on the schematic.
Mixer
@I
The Mixer is double balanced and has about 6
dB
conversion loss. It mixes the 3 MHz IF
signal from A4A7 with the 18.4 MHz LO signal from the LO Driver and Buffer Amplifier to
produce a 21.4 MHz signal through the 21.4 MHz
Bandpass
Amplifier to A4A5.
21.4 MHz
Bandpass
Amplifier
@
This is a common emitter amplifier with about 7
dB
of gain. It is preceded by a wide
(BW
z
5 MHz)
bandpass
filter (R61, C32, and L2) and followed by a narrow (BW
z
10
kHz)
bandpass
(Tl,
Yl,
L8, and R60).
Th
e
wide filter attenuates harmonics of the 18.4 MHz LO,
and the narrow filter attenuates the fundamental of the 18.4 MHz LO. 18.4 MHz NULL
adjustment C31 compensates for the case capacitance of the crystal. The crystal
Yl
and
inverting transformer
Tl
are driven by an emitter follower Q4. The output emitter follower is
turned on and off by the SWITCH line.
A4A6

A4A6A2
Down
Converter,
Circuit
Description
For resolution bandwidths
51
kHz,
A4A6A2 Down Converter converts the 21.4 MHz IF signal
from A20 Third Converter down to a 3 MHz IF signal. For resolution bandwidths
23
kHz,
the 21.4 MHz is not converted but is sent through
A4A6Al
Up Converter to A4A5 Step Gain.
Switch
@
and
50
Ohm Driver
@
For bandwidths >3
kHz,
the SWITCH line is +15 V and Q7 is off. R38 in the LO Driver
and Buffer Amplifier pulls the collector of Q7 to less than 0 V. This forward biases CR3
and reverse biases CR5, passing the 21.4 MHz IF signal to the 50 Ohm Driver, where it is
converted to a 50 Ohm system (6
dB
loss) and sent to
A4A6Al.
For bandwidths
_<l
kHz,
the SWITCH line is 0 V, turning Q7 on. The collector Q7 goes to
almost
+15
V, which turns CR5 on (shorting any signal that might pass through CR3) and
CR3 off. Q7 also turns the LO on.
LO Driver and Buffer Amplifier
@I
This circuit is only on for bandwidths
51
kHz.
It consists of an emitter follower
QS
driving
a common base stage Q5 which in turn drives a common emitter stage Q2. The proper bias
voltages and signal levels are shown on the schematic.
Mixer and Driver
@
Ql
is an emitter follower driving a step-down transformer. The turns ratio is about
4-l/2
to
1, which yields a 12
dB
loss and drives the Mixer from a low impedance. The Mixer has an
additional 5
dB
loss.
3 MHz
Bandpass
Amplifier
@
This amplifier compensates for the losses of the transformer
Tl
and the mixer
Ul.
The filter
at the output, consisting of L5, C22, and R52, has less than 1
dB
of loss at 3 MHz.

A4A6
A4A6
Down/Up
Converter,
Troubleshooting
If the resolution bandwidths less than 3
kHz
are not working properly, the fault is most likely
on the Down/Up Converter or the 3 MHz Bandwidth Filter boards.
If only noise is displayed, check the voltage on the SWITCH control lines. If the SWITCH
line is working, the 18.4 MHz LO signal levels should be tested. The 18.4 MHz Oscillator is
located on the A4A5 Step Gain board.
A4A6A2R33*
may have to be changed if mixer
A4A6A2Ul
is replaced. Refer to the
Performance Tests and Adjustments Manual for the correct procedure for selecting this value.
Note that the SWITCH control line voltage is different on the
A4A6Al
Up Converter board.
This is due to a 100 Ohm resistor, R4, on the A4AlO IF Video Motherboard.

Description
A4A7
3 MHz Filter is a variable bandwidth filter centered at 3 MHz. The bandwidths are
controlled from 10 Hz to 300 Hz in a 1, 3, 10 sequence by lines that have the same name
as the bandwidth they activate. When none of the lines is activated, the filter has a 1
kHz
bandwidth.
The filter has five poles which are almost identical. Only one is described in detail. Each pole
has a negative output impedance to compensate for the series resistance of the crystal, but it
is adjustable in only two poles.
4th Pole

The basis of the buffer amplifier is a complementary feedback pair including
Q9
and
&lo.
(See Figure 1.)

Figure 1. Complementary Feedback Pair, Simplified Schematic
The bias current through
QlO
is 0.7
V/1620
4 mA, and the total current through
QlO
plus
Q9
is set by
Rr,
to be about 20 mA. The source voltage of
QlO
should always be higher than
the gate voltage.
The circuit as shown in Figure 1 has no gain. R39, R36, and C26 are added (see schematic) so
this stage has a gain of:
R38
G=l+=aldB
Rr,
is replaced by a 20
mA
current sink. (See Figure 2.)

Figure 2. Complementary Pair with Current Sink
The description to this point is sufficient to understand how the circuit is biased. The 3 MHz
operation is described in the following paragraphs.
Potentiometer R41 is added and the signal from the collector of
Q9
is fed into the base of Q7
by C28. (See Figure 3.)

SUPPLY
Figure 3. Buffer Amplifier with Negative Output Impedance
The circuit still operates the same because there is no load on the emitter of Q7 and hence
no collector current. (Remember, this is 3 MHz AC operation.) If a load (Y4) is added
to the emitter of Q7, collector current is developed and this current is fed back into the
2
A4A7
complementary pair
Q9,
&lo.
The sense of this current is such that the feed back is positive.
The more load, the more positive feedback is developed. The more positive feedback, the
more gain the amplifier has. This implies negative output impedance. The magnitude of the
negative output impedance is the resistance to which R41 is set.
QS
and the SYM cap are added to cancel the effect of the case (parallel) capacitance of the
crystal. (See Figure 4.) R94, R96 and other resistors are switched in to change bandwidths.
C31 and C62 (not shown) are in series with the crystal to tune the center frequency to
precisely 3 MHz. The negative output impedances of the amplifier is set to compensate for
the series resistance of the crystal so that as different bandwidths are selected, the amplitude
(overall gain) does not change. If the relative gain of the filter assembly is too low in the
10 Hz BW, and cannot be corrected by R41 and R30, three common problems are:
n
All five crystals are not tuned close enough to the same center frequency.
n
The series resistance of one or more of the crystals is too high.
n
The output impedance of one or more of the buffer amplifiers is not negative enough.

Filter,
Circuit
Description
A4A8 Attenuator-Bandwidth Filter and
A4A4
Bandwidth Filter operate at 21.4 MHz and
are variable in bandwidth from 3
kHz
to 3 MHz. The narrower bandwidths (3
kHz
through
30
kHz)
are obtained from five synchronously tuned crystal filters; the wider bandwidths (100
kHz
through 3 MHz), from four synchronously tuned LC tank circuits (the bandwidths 10
Hz through 1
kHz
are obtained from
A4A7
3 MHz Filter). The Bandwidth Filter assemblies
are on similar printed- circuit boards.
A4A8
has two LC filters and two crystal filters, and
A4A4
has two LC filters and three crystal filters (A4861 Up Converter has a single 21.4 MHz
crystal that is used only for bandwidths
51
kHz).
These six crystals comprise a matched set
and must be replaced as such. The replacement assemblies are shipped without crystals, so
the crystals from the replaced boards must be used again.

For the lower gain settings of 0
dB
and -10
dB
(activated by
AlOdB
and
A20dB,
respectively), additional collector resistance is switched in by CR3 or CR2, thereby lowering
the gain.
Input Buffer Amplifier
@
The unity gain Input Buffer Amplifier functions as a noninverting op amp. (See Figure 1.)
Figure 1. A4A8 Input Buffer Amplifier, Equivalent Circuit
In the crystal mode (3
kHz,
10
kHz,
and 30
kHz
bandwidths), the amplifier includes Q2. The
biasing of the amplifier is independent of its ac (21.4 MHz) o eration but is very critical for
p
its proper functioning. If a malfunction occurs, the dc bias should be checked first.
A4A8
1
The current through
QlO
is determined by the difference between two current sources, one
involving Q2 and the other involving
Qll.
(See Figure 2.) The most convenient way to find
the current from each source is to measure the voltage across each emitter resistor (a 1 k
Ohm resistor should be used in series with the voltmeter probe tip to prevent the circuit
from oscillating and giving an erroneous reading). For Q2, the current through R60 must be
included. If results are inconsistent, the emitter resistor should be checked also. Check to see
that the BW5 line is at approximately -0.5 V for bandwidths 530
kHz.
02,ETC.
Figure 2. A4A8 Input Buffer Amplifier, Current Sinks
In the LC mode (the four wider bandwidths), the BW5 line goes to approximately $14.8 V
and turns off the current source Q2. The current supplied by Q2 in the crystal mode is now
supplied through CR5 and R15 from the BW5 line. In the LC mode, the current through
QlO
can be found by subtracting the current through R5 from the current through R12. C76, L34,
and C77 form a feedback tank circuit to suppress oscillations.
Buffer Amplifier
@
The Buffer Amplifier is similar to the input Buffer Amplifier. The input is selected by the
BW5 line from CR9 in the LC mode or from CR8 in the crystal mode.
In the crystal mode, the current through Q4 is determined by the difference between the
current
sourced
by
QS
and that sunk by Q5 (about 4
mA).
A significant deviation from
this current should be reflected by the gate-to-source voltage of Q4. The source should be
at least 0.4 V more positive than the gate, but not more than 2.0 V more positive. If the
difference is less than 0.4 V, the FET current is too high; if the difference is greater than 2.0
V, the FET current may be too low. In the either case the FET could also be defective. To
determine precisely the current through Q4, the difference between the current through R47
and that through R61 should be subtracted from the current through R41. If the results are
inconsistent, check the above-mentioned resistors.
In the LC mode of operation, current is supplied through R44 and CR11 from the BW5 line
instead of through
QS.
The difference between the current through R44 and that through
R41 yields the FET current. C79, L35, and
C80
form a feedback tank circuit to suppress
oscillations.

Crystal Filtering Circuits
@
@
The bandwidths 3
kHz,
10 Hz, and 30
kHz
are obtained by crystal filtering in the First
Crystal Pole and Second Crystal Pole circuits. The crystals are used in series resonant mode
and can be modeled as a series resonant circuit with a parallel capacitance. (See Figure 3.)
Figure 3. Quartz Crystal, Simplified Schematic
The parallel capacitance (C,) and series resistance
(&)
are not desired and are compensated
for in the circuit, as shown in the equivalent circuit of a single pole of crystal filtering. (See
Figure 4.)
Figure 4. Crystal Filtering Pole, Equivalent Circuit
Since the two crystal filtering circuits are almost identical, the following description is for the
First Crystal Pole circuit only.
The PIN diode CR7 functions as a variable resistor at 21.4 MHz. As the resistance is lowered
by increasing the current in the BW63 line, the bandshape becomes narrower. The bandwidth
of one pole widens to approximately 80
kHz
when CR7 is turned off completely at the 30
kHz
BW setting. For a five-pole filter, the bandwidth of each pole is about 2.6 times the
bandwidth of all five poles taken together.
A simplified schematic of a crystal pole, including compensation for
R,
and
C,
in the crystal
and input capacitance of the buffer amplifier, is shown in Figure 5.

Figure 5. Crystal Pole, Simplified Schematic
The SYM adjustment Cl3 compensates for
C,
by producing a current
(-11)
that is equal
to the current
(11)
through
C,
of the crystal but opposite in phase. These currents cancel,
nullifying the effect of C-o-. The positive feedback from the collector of Q2 generates a
negative output resistance that cancels
R,
of the crystal. This is approximated by resistor R16
in the Input Buffer Amplifier and XTL adjustment R40 in the Buffer Amplifier.
The input capacitance of the Buffer Amplifier, printed circuit board capacitance, PIN diode
capacitance, and the centering (CTR) capacitor C29 are in parallel resonance with L8. These
components have negligible effect on the band shape. As long as C29 has sufficient range to
“dip” the band shape, they can be ignored in analyzing the remainder of the circuit.
The PIN diode CR7 controls bandwidths from 3
kHz
to 10
kHz.
For the 30
kHz
bandwidth,
CR7 is back biased and R26 sets that bandwidth. If the 30
kHz
bandwidth is much too
narrow, even with CR7 back biased, the circuit might be loaded by a bad buffer amplifier
(Q4, Q5). If the bandwidth is only slightly narrow, it may be widened by selecting a new
value for R26*. If the narrowest bandwidth (3
kHz)
has too little gain, and it cannot be
increased enough by XTL adjustment
R40,
then the crystals may have too high a series
resistance (defective crystal), the output resistance may not be negative enough (defective
Buffer Amplifier or &3), or the crystals may have drifted too far apart in frequency.
LC Filters
@J
@
The two LC filtering circuits are used for the wider bandwidths (100
kHz
through 3 MHz).
They are similar in function; the Second LC Pole circuit is described. A schematic of the
simplified equivalent circuit is shown in Figure 6.

The Q (bandwidth) is set by the resistance of the PIN diode CR18. A more detailed

Figure 7. Second LC Pole Circuit, Simplified Schematic
The LC filter pole comprises an inductor (L14) in parallel with four capacitors: C48, C46
(LC CENTER),
and the series combination of
C49*
and
C81*.
The parallel circuit is driven
through PIN diode CR18, which functions as a variable resistor. The BW7 line sets the
current through CR18. Higher resistance results in narrower bandwidth.
C67 and L15 tune out the case capacitance of CR18. R55* sets the 100
kHz
bandwidth when
CR18 is back biased (that is, highest resistance). CR17 is controlled by the LC adjustment
R35 and compensates for losses in the parallel resonant circuit. In the First LC Pole circuit,
fixed resistor
R29*
replaces CR17.
Low gain in one of the poles in the 100
kHz
bandwidth is caused by:
1. Broken or cracked metalized-glass inductor (often intermittent).
2. The pole being centered at some frequency other than 21.4 MHz.
3. Insufficient feedback from the buffer amplifier.
4. Defective buffer amplifier that is loading the circuit.
If the 10
kHz
bandwidth amplitude is correct, but that of the 300
kHz
bandwidth is too
low, either C66 or C67 is not properly adjusted. If the 300
kHz
amplitude is too high, the
four LC poles are not tuned close enough to the same frequency. In either case, refer to the
Performance Tests and Adjustments Manual.

Attenuator-Bandwidth
Filter,
Troubleshooting
As an aid in troubleshooting, critical dc voltages for proper operation are indicated at several
nodes on the accompanying schematic.
If the resolution bandwidths from 3
kHz
to 3 MHz have low gain or incorrect bandwidth,
either this board or the
A4A4
Bandwidth Filter board may be defective. To determine which
board is faulty, disconnect the 97 cable from
A4A8Jl
and connect it to
A4A6Jl.
If the signal
is then 3 to 5
dB
lower than expected (CAL OUTPUT is -13 to -15
dBm)
or the bandwidth
is 30 to 60 percent wider than expected
(1MHz
(REsBW_)
is 1.3 to 1.5 MHz), then A4A8 is
suspect.
Control line BW5 determines whether the LC filters or the crystal
filters
are selected. If this
line does not switch,
A4A9Q3
on the IF control board should be checked. BW63 controls the
crystal mode resolution bandwidths from 3
kHz
to 30
kHz.
The LC resolution bandwidths
from 100
kHz
to 3 MHz are controlled by BW7. If any of the control line voltages in Note 5 of
the schematic diagram are incorrect, signals from A4A9 IF Control should be checked.
Operation of the AlOdB and A20dB circuitry can be determined by the following method.
Connect a 355D attenuator between the CAL OUTPUT and the input of the spectrum
analyzer. Set this attenuator to 90 db, press Instrument Preset, and key in the following:

Description
Control information for A4 IF-Video assembly is transmitted over the Instrument Bus from
the Al5 Controller and decoded by the
A4A9
IF Control.
Address Decoder
@J
The Address Decoder monitors ADR O-4 and activates the input latches for addresses 20 and
21 when control line LTIO goes low. Address 20 activates input latches
UlO,
U14, and U17
(U6, U8, and
U9
in early versions of
A4A9).
Address 21 activates input latches U7,
U18,
and
U20
(U3,
UlO,
and
Ull
in early versions of
A4A9).
Table 7 of the troubleshooting information
shows the line levels of the ADR control lines for addresses 20 and 21.
Input Latches
@
Input latches hold the IOB levels present at the input of the latch when the address decoder
activates the input latch. Six input latches are activated (clocked) by 2 control lines (Address
20 and Address 21) from the Address Decoder
@.
For example, when Address 20 goes high,
input latches
UlO,
U14, and U17 (U6, U8, and
U9
in early versions of
A4A9)
are activated.
The levels of all sixteen IOB lines, IOBO through IOB15, are held at those same levels at the
outputs of
UlO,
U14, and U17.
AO.0
to A15.9
dB
Control
@
The
AO.0
to A15.9
dB
Control circuitry provides attenuation control voltages for the A4A5
Step Gain. Up to 14
dB
of attenuation is accomplished by switching on discrete attenuation
steps on the
A465
Step Gain via the A8dB, A4dB, and A2dB control switching lines. The
smaller attenuation steps (0.1
dB
through 1.9 dB) are accomplished by controlling the amount
of dc current through a PIN diode attenuator on A4A5. One of the outputs of
Ull
goes low
when a particular step of attenuation is selected. The output of
U19A
also goes low when an
odd step of attenuation is desired (0.1 dB, 0.3
dB,
1.5
dB,
and so forth). The fixed resistors
tied to edge- connector pin P2-7 determine the
amout
of current through (and hence the
attenuation of) the PIN diode attenuator. The operation of the attenuator is described in
A4A5.

Bandwidth Control
@
Bandwidths from 3 MHz to 100
kHz
(BW
2
+14.8V)
These bandwidths are produced in the 21.4 MHz IF by four parallel tank circuits (two in
A4A4
Bandwidth Filter and two on A4A8 Attenuator-Bandwidth Filter). Their Q (which
determines bandwidth) is controlled by PIN diodes used as variable resistors. The resistance
of these PIN diodes is determined by the average current through them, which is generated
by
Q9.
Either R60, R61, or R62 is switched in by U2, depending on which bandwidth had
been selected. These potentiometers (3 MHz, 1 MHz, and 300
kHz)
determine the amount of
current sunk by
Q9,
which in turn determines the bandwidth. If no current is sunk by
Q9,
the filters go to their highest Q (determined by factory-selected resistors), which yields the
100
kHz
bandwidth.
Bandwidths from 30
kHz
to 3
kHz
(BW7 =
-0.6V)
These bandwidths are produced in the 21.4 MHz IF by five crystal filters (two in A4A8 and
three in
A4A4).
Their Q (which determines bandwidth) is controlled by PIN diodes, the same
as for the wider bandwidths. Refer to the preceding discussion of the wider bandwidths.
QlO
is the current sink for bandwidths from 30
kHz
to 3
kHz.
The amount of current it sinks is
selected by U2 and adjusted by potentiometers R65 and R66 (10
kHz
and 3
kHz),
depending
on which bandwidth is selected. If no current is sunk by
&lo,
the filters go to their lowest Q
(determined by factory-selected resistors), which yields the 30
kHz
bandwidth.
Ql
should be
off except for the 3 MHz to 100
kHz
bandwidths.
Bandwidths from 1
kHz
to 10 Hz (SWITCH =
OV)
These bandwidths are produced in the 3 MHz IF
(A4A7)
by five crystal filters. The Q of
these filters is controlled by resistors which are switched in by diodes. These, in turn, are
controlled by Q25, Q26, Q28, and Q29. The transistors switch lines which are named after the
bandwidths they produce. Q27 is on (saturated) only for bandwidths 1
kHz
through 10 Hz.

Troubleshooting
If the BW5 control line is not switching, Q3 is most likely defective. If Q3 is found to be
defective, check
QS
to determine if it has failed also.
Figure 1 is reproduced from the troubleshooting for the A4A5 Step Gain. It shows the
results of a quick test to determine proper operation of the 0.0 to 1.9
dB
attenuator section
of the
AO.0
to A15.9
dB
control. As the figure shows, the steps are not exactly 0.1
dB.
If the
steps are not continuously increasing (monotonic), either a control line is not switching or
a switching diode is defective. Table 6 will be useful in determining when a control line is
active.

The absolute step amplitudes can be determined with the MARKER A function. The
reference steps are 0.0
dB
and 0.9
dB.
In the Linear mode the error should be less than
50.12
dB.
The 1 dB, 1.4 dB, and 1.8
dB
steps are controlled by factory selected resistors. If one of these
steps is in error by more than
f
0.12

in the Linear mode, refer to the adjustment section
of the Performance Tests and Adjustments Manual for the procedure to determine the correct
value. The other steps should be f0.2

in the Linear mode.

Tables 1 through 8 provide information that is useful in troubleshooting the A4A9 IF Control
Assembly.
Table 1 (0.0 to -1.9
dB
Control Truth Table) and Table 2 (0 to -9
dB
Control Truth Table)
illustrate the
A4A9
IF Control control line switching for the A4A5 Step Gain variable and
fixed attenuators. These tables must be used in conjunction with one another. Table 1 is the
truth table for the variable attenuator control lines (A.1
dB,
A.2
dB,
A.4
dB,
A.8
dB,
and Al
dB) of the Input Latches (A) function block on the
A4A9
assembly. Table 2 is the truth table
for the fixed attenuator control lines (A2 dB, A4 dB, and A8 dB) of the Input Latches (A)
function block on the A4A9 assembly. Together these two tables can be used to determine the
states for each of these control lines for reference levels in 0.1
dB
steps. As the reference level
changes, 0.1
dB
to 9.9
dB
of attenuation is added or removed from the IF signal path.
Note
I
vb
When using Table 1 (0.0 to -1.9
dB
Control Truth Table) and Table 2 (0 to
-9
dB
Control Truth Table) for troubleshooting, the reference level must be
input using the front-panel keyboard. The truth tables (Tables 1 and 2) are
not valid when the spectrum analyzer is using correction factors (KSX) or
when the RPG knob is used to change the reference level. The fixed and
variable attenuators are set differently than the truth tables show in these
modes.
Table 1 shows the variable attenuator control line states for each
.l
dB
step of reference level
between 0
dBm
and -1.9
dBm.
This table repeats for every 2
dB
change of the spectrum
analyzer’s reference level. For example, in addition to this being the truth table for reference
levels between 0.0 and -1.9 dBm, it is also the truth table for reference levels between -2.0
and -3.9
dBm,
between -4.0 and -5.9
dBm,
between -6.0 and -7.9
dBm,
between -8.0 and
-9.9
dBm,
and so forth.
Table 2 shows the
fixed
attenuator control line states of reference levels between 0 dBm and
-9
dBm.
The fixed attenuators change the reference level in 2
dB
steps. This table repeats
itself with every 10
dB
change of the spectrum analyzer’s reference level. For example, in
addition to this being the truth table for reference levels between 0 and -9
dBm,
it is also
the truth table for reference levels between -10 and -19
dBm,
between -20 and -29
dBm,
between -30 and -39
dBm,
and so forth.
To determine the levels for all control lines at the outputs of the input latches, both Table 1
and Table 2 must be used. For example, if the reference level of the spectrum analyzer is 0.0
dBm
(the same as -0.0
dBm),
Table 1 shows that the states of control lines A.1
dB,
A.8
dB,
and Al
dB
are high. Table 2 shows that the state of control line A8
dB
is high. Thus when
the spectrum analyzer has a reference level of 0.0 dBm, control lines A.1
dB,
A.8 dB, Al
dB,
and A8
dB
are high at the output of the input latches (Function Block A).
As another example, if the spectrum analyzer has a reference level of -33.4
dBm,
use the
-2 (-3)
dBm
row of Table 2 because it is representative for reference levels from -30
dB
through -39
dBm.
Use the
-1.4
dBm
column of Table 1 because Table 1 is representative for
reference levels between -32 dBm and -33.9
dBm.
Using Tables 1 and 2, a reference level
of 33.4
dBm
has control lines A.1
dB,
A.4
dB,
A2
dB,
and A4
dB
high at the output of the
input latches.

Options
The HP 85662A IF-Display Section has several options that may be ordered. Each option is
listed below with a brief description of the option and the changes to the IF-Display Section.
Three of these options (Option 067, Option H96, and Option 462) require substantial printed
circuit board changes and have separate sections in this manual. The PC board changes of
these options are documented either behind the tab for the assembly that changed or behind
the tab for the option that requires a PC board change. Parts lists for option assemblies are
located behind the tab of that option. Component locations and schematic diagrams for
option assemblies are incorporated onto the component location or schematic diagram of the
standard version where possible. However, many instances require that an option assembly
have its own component location or schematic diagram. These versions of the component
location or schematic diagram are located behind the tab for that option.

Option 462 1
A4A9
IF
Control,
Circuit
Description
Control information for A4 IF-Video assembly is transmitted over the Instrument Bus from
the Al5 Controller and decoded by the
A4A9
IF Control.
Address Decoder
@
The Address Decoder monitors ADR O-4 and activates the input latches for addresses 20 and
21 when control line LTIO goes low. Address 20 activates input latches
UlO,
U14, and U17
(U6,
U8,
and
U9
in early versions of
A4A9).
Address 21 activates input latches U7, U18, and
U20
(U3,
UlO,
and
Ull
in early versions of
A4A9).
Table 7 of the troubleshooting information
shows the line levels of the ADR control lines for addresses 20 and 21.
Input Latches
@
Input latches hold the IOB levels present at the input of the latch when the address decoder
activates the input latch. Six input latches are activated (clocked) by 2 control lines (Address
20 and Address 21) from the Address Decoder
@.
For example, when Address 20 goes high,
input latches
UlO,
U14, and U17 (U6, U8, and
U9
in early versions of
A4A9)
are activated.
The levels of all sixteen IOB lines, IOBO through IOB15, are held at those same levels at the
outputs of
UlO,
U14, and U17.
AO.0
to A15.9
dB
Control
@
The
AO.0
to A15.9
dB
Control circuitry provides attenuation control voltages for the
A4A5
Step Gain. Up to 14
dB
of attenuation is accomplished by switching on discrete attenuation
steps on the
A4A5
Step Gain via the A8dB, A4dB, and A2dB control switching lines. The
smaller attenuation steps (0.1
dB
through 1.9 dB) are accomplished by controlling the amount
of dc current through a PIN diode attenuator on A4A5. One of the outputs of
Ull
goes low
when a particular step of attenuation is selected. The output of
U19A
also goes low when an
odd step of attenuation is desired (0.1
dB,
0.3
dB,
1.5 dB, and so forth). The fixed resistors
tied to edge- connector pin P2-7 determine the
amout
of current through (and hence the
attenuation of) the PIN diode attenuator. The operation of the attenuator is described in
A4A5.
IF Gain Control
(6~
The IF Gain Control interfaces with A4A5 Step Gain, the Log Amplifiers in
A4A2,
A4A3,
and
A4Al
Video Processor. Table 5 shows the conditions under which the steps are used.
Bandwidth Control
@
Bandwidths from 3 MHz to 100
kHz
(BW
2
+14.8V)
These bandwidths are produced in the 21.4 MHz IF by four parallel tank circuits (two in
A4A4
Bandwidth Filter and two on
A4A8
Attenuator-Bandwidth Filter). Their Q (which
determines bandwidth) is controlled by PIN diodes used as variable resistors. The resistance
of these PIN diodes is determined by the average current through them, which is generated
by
Q9.
Either R60, R61, or R62 is switched in by U2, depending on which bandwidth had
been selected. These potentiometers (3 MHz, 1 MHz, and 300
kHz)
determine the amount of
current sunk by
Q9,
which in turn determines the bandwidth. If no current is sunk by
Q9,
2 Option 462
the filters go to their highest Q (determined by factory-selected resistors), which yields the
100
kHz
bandwidth.
Bandwidths from 30
kHz
to 3
kHz
(BW7 =
-0.6v)
These bandwidths are produced in the 21.4 MHz IF by five crystal filters (two in A4A8 and
three in
A4A4).
Their Q (which determines bandwidth) is controlled by PIN diodes, the same
as for the wider bandwidths. Refer to the preceding discussion of the wider bandwidths.
QlO
is the current sink for bandwidths from 30
kHz
to 3
kHz.
The amount of current it sinks is
selected by U2 and adjusted by potentiometers R65 and R66 (10
kHz
and 3 kHz), depending
on which bandwidth is selected. If no current is sunk by
&lo,
the filters go to their lowest Q
(determined by factory-selected resistors), which yields the 30
kHz
bandwidth.
Ql
should be
off except for the 3 MHz to 100
kHz
bandwidths.
Bandwidths from 1
kHz
to 10 Hz (SWITCH =
OV)
These bandwidths are produced in the 3 MHz IF
(A4A7)
by five crystal filters. The Q of
these filters is controlled by resistors which are switched in by diodes. These, in turn, are
controlled by Q25, Q26, Q28, and Q29. The transistors switch lines which are named after the
bandwidths they produce. Q27 is on (saturated) only for bandwidths 1
kHz
through 10 Hz.
Option 462 3
A4A9
IF
Control,
Troubleshooting
If the BW5 control line is not switching, Q3 is most likely defective. If Q3 is found to be
defective, check
QS
to determine if it has failed also.
Figure 1 is reproduced from the troubleshooting for the
A4A5
Step Gain. It shows the
results of a quick test to determine proper operation of the 0.0 to 1.9
dB
attenuator section
of the
AO.0
to A15.9
dB
control. As the figure shows, the steps are not exactly 0.1
dB.
If the
steps are not continuously increasing (monotonic), either a control line is not switching or
a switching diode is defective. Table 7 will be useful in determining when a control line is
active.

Figure 1. 0.1
dB
Step Gain Display
The absolute step amplitudes can be determined with the MARKER A function. The
reference steps are 0.0
dB
and 0.9
dB.
In the Linear mode the error should be less than
f0.12
dB.
The 1
dB,
1.4 dB, and 1.8
dB
steps are controlled by factory selected resistors. If one of these
steps is in error by more than
f
0.12
dB
in the Linear mode, refer to the adjustment section
of the Performance Tests and Adjustments Manual for the procedure to determine the correct
value. The other steps should be f0.2
dB
in the Linear mode.
Tables 1 through 8 provide information that is useful in troubleshooting the A4A9 IF Control
Assembly.

minimum-order quantity imposed on orders made through the Hewlett-Packard Sales and
Service Offices when the orders require billing and invoicing.)
3. Prepaid transportation. (There is a handling charge added to each order.)
4. No invoices.
A check or money order must accompany direct-mail orders. Mail-order forms and specific
ordering information are available from Hewlett-Packard Sales and Service Offices.
