A8 Rectifier/AS Power Line Module
Printed Circuit Board Edge Connector Contact Cleaning
Materials
w
Lint-free cloth or equivalent (HP Part Number 9310-0039, Check Digit 3).
w
Solution of 80% electronics-grade isopropyl alcohol and 20% water.
w
Static-free work station.
Procedure
1. Dampen the cloth with the alcohol and water solution and scrub the edge connector
contacts vigorously, using a circular motion. Polish one side of the board at a time until
the contacts shine, keeping the cloth damp to dissolve contaminants and reduce static
electricity.
General Information 3
2. Using a clean cloth, dry the contacts by wiping from their inside to outside edge. This
prevents particles from building up on the contact edges.
Caution
9
Do not use erasers to clean the edge connectors. They cause microscopic
damage to the contact surface, removing the thin gold plating and exposing
the nickel underplating, which eventually corrodes. Erasers also leave a film on
the contact and generate static electricity.
Do not use paper of any kind to clean the edge connector contacts. Paper or
lint particles left on the edge contact surface can cause intermittent electrical
connections.
Do not touch contact or trace surfaces with bare hands. Always handle the
board by its edges.
HP-IB Address Selection
The HP-IB address for the HP 8566B is preset at the factory by means of a five-segment
binary switch located on the Al5 Controller Assembly. This switch is set to the binary
number 11111 which corresponds to a decimal equivalent of 31. The number 31 is a special
instruction code that commands the instrument to use the last input address stored in
memory. This stored HP-IB address is ASCII 2R (d
ecimall
18) and determines the address to
be used on “power up.”
The HP-IB address may be changed to any of the addresses listed in Table 2 by resetting the
HP-IB
address
switch to correspond to the binary equivalent of the desired ASCII character
or decimal value as indicated in the table. The five-segment switch is illustrated in Figure 1
and is shown in its preset position (decimal 31).

The HP-IB address may also be changed from the front panel or programmed via a controller
using a special shift key function (KSP). This address remains in effect as long as the
instrument memory has power from either the ac line or the internal battery. However, if
this stored address is lost, the default address is the factory preset decimal 18 (ASCII 2R).
For additional information on the HP-IB address, refer to the Operating and Programming
Manual.

(50,000 feet)
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 the
Hewlett-Packard offices. Part numbers and descriptions of the packaging materials are listed
in Figure 2.
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 2 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.
6 General Information
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.
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.

Schematic Symbols for Digital Integrated Circuits
The following is a guide to the symbols used for digital or logic ICs in this manual. The
symbology is based upon American National Standard ANSI Y32.14, Graphic Symbols for
Logic Diagrams (Two-State Devices), but does not strictly follow the standard. Figure 6
should be consulted for the explanation of digital IC symbols used in Sections VIII and IX.
Definitions
Logic Element. The part or parts of a logic device symbol having a well-defined logic function
(OR, AND, FLIP-FLOP, and so on) and one or more outputs. The inputs of a logic element
may be data or control inputs; the outputs are data outputs.
Control Block. The part of a logic device symbol to which all logic lines common to a group of
logic elements are connected. Lines connected to a control block are control lines.
Function Label. The notation within a logic device symbol that denotes its overall logic
function (counter, shift register, multiplexer, and so on)
Line Label. The symbol or abbreviation associated with an output or input line that defines
the action of the line.
Indicator Symbol. A symbol associated with an input or output line which defines the active
state or special characteristics of the line.

Note:
The logic negation symbol (0) 1a one gives no information about the actual voltage levels used
in a digital cirucit. For this reason the type of logic system (positive or negative) must be
specified. In this manual, unless otherwise noted on the schematic, the logic system is positive;
that is, the more positive voltage level is the HIGH or l-state and the less positive level is the
LOW or O-state.

Special Messages
As a convenience to the operator and as an aid in servicing, eleven messages can appear in
the upper right corner of the CRT display. (Ten of these messages are shown in Figure 1.)
Five of the messages inform the operator of possible erroneous data from improper instrument
operation. The other six provide warnings of instrument malfunctions that must be repaired
for proper instrument operation.
A brief description of each message follows. The troubleshooting information listed is not
meant to be exhaustive. Refer to the appropriate Troubleshooting Block Diagram and
Troubleshooting Hints for more detailed information.
EXT REF
Indication to operator that the external frequency reference is selected.
MEAS
UNCAL
A warning to the operator that the amplitude/frequency data on the CRT is invalid because
the analyzer’s sweep speed is too fast for the selected bandwidth.
A warning to the operator that the analyzer settings displayed on the CRT have been changed
but the trace data has not been updated. This would occur, for example, when Trace A view
is selected and then Center Frequency is changed.
OVEN COLD
Indication that the frequency reference oven temperature is too low. There will be an oven
cold indication normally for about 10 minutes after the line power is initially applied to
the instrument. (The oven is powered and should stay warm as long as the instrument
is in STANDBY.) The time base HOVC (High = Oven Cold) signal is routed to the Al2
Front-Panel Interface for generation of this message.
BATTERY
A warning to the operator that the CMOS memory on the Al5 Controller has probably
lost the stored instrument states. The warning can only appear at instrument turn on. If it
appears, the instrument automatically reinitializes all the instrument states to the instrument
preset condition. The battery warning can be caused by a problem with the Al5 CMOS
memory power supply circuit. Performing the “long POP” instrument check (see RF Section
Digital Troubleshooting) erases the stored instrument states and causes a battery warning to
appear at instrument turn on. The HP-IB address is also lost. The battery warning can be
removed by pressing
[GHz’
and the HP-IB address restored by keying in
(jZiK)
(ZZKj
[desired address]
[jGiZi?Z).

This function permits the analyzer to sweep at normal sweep rates ignoring any phase lock
flag indications. For example, if a YTO UNLOCK problem exists, the analyzer will sweep
slower since it spends most of its time trying to lock the YTO at center frequency during
retrace. By performing the phase lock inhibit, the analyzer does not waste time trying to lock
the YTO, so the front panel keys and display can be used as in normal operation. Note that
the displayed frequencies will probably not be accurate.
Trace Detection
Three different sampling modes are used by the analyzer in converting the video signal; these
are positive peak, negative peak, and sample. Normally the analyzer selects the proper mode
for each measurement, but these can be manually selected to verify proper operation. The
mode selected is indicated on the upper left side of the CRT display when under manual
control. (See Figure 1.) For example, a signal could be expanded to 2 dB/div to eliminate the
noise floor, and then by comparing a positive peak trace measurement, it can be determined
if the gains and offsets of the three modes are properly aligned. All three should appear the
same on a stable, noise-free signal. When in the noise, the positive peak should display the
highest noise peaks, negative peak mode should display the lowest noise levels, and sample
mode should display values between the positive and negative peaks.

Error Correction Routine
The internal Error Correction Routine available by pressing
@iFi)
w[~~~~~~~~~
SPAN]
(KSW) is also useful as a diagnostic aid. If a malfunction causes the routine to stop, restart
it and note the control settings (RES BW,
ATTEN,
REF LEVEL,
LOG/LIN,
etc.) when
the failure occurred. If the routine runs, the correction factors can be displayed by pressing
(SHIFT]
“‘@
(KSw).
Figure 2 displays the data for a typical instrument. Table 2 gives the
parametric information, specifications and a place to start the troubleshooting procedure.
Caution must be exercised in interpreting the correction factor data. Wrong conclusions
can be reached by not understanding how the internal program runs. The program assumes
that the input signal level is -10.0
dBm.
Any error in this level translates to the correction
factors; therefore, the Amplitude Accuracy test
(RECALL]
8 should be performed first. The
internal program runs in the LIN mode while
[RECALL]
8 is in 1 dB/LOG mode. Large offsets
in LOG/LIN offset (lines 1 and 14) will cause errors in the data.

Sweep System Block Diagram Description
The HP 8566B Spectrum Analyzer sweep system consists of the following modes:
Continuous Sweep; Free Run Trigger
Several different assemblies are involved in the HP 8566B sweep system. The Al6
Scan Generator generates the 0 to 10 V sweep ramp. The ramp converter on the A3A8
Analog-Digital Converter and the Digital Storage Processor Section digitize this ramp into
a
10-bit
sweep address. When the sweep address reaches the marker address, the Digital
Storage Processor Section outputs a RSHS (Low = Reset High Sweep) pulse. This signal
resets the High Sweep flip-flop on the
A3Al
Trigger assembly. HSWP (High Sweep) goes low
and the current source charging the sweep capacitor on Al6 is shunted to ground, stopping
the sweep ramp at its present value. The negative transition on the HSWP line generates a
Service Request on Al2 Front-Panel Interface forcing LSRQ low which sets LSTP (Low Stop)
high. This “wakes up” the Al5 Controller. The Controller then reads the sweep address from
the Digital Storage Processor Section. If it corresponds to the end of the sweep, the Al5
Controller outputs a sweep reset command to the Al6 Scan Generator, resetting the sweep
ramp to 0 V. After all Service Requests have been handled (LSRQ is high), the Al5 Controller
starts the sweep by issuing a set HSWP command to the
A3Al
Trigger. The Al5 Controller
then issues a stop command to the Al2 Front-Panel Interface assembly that forces LSTP low,
stopping the Controller. After a 500 ps delay on
A3Al
Trigger, HSWP goes high, the sweep
ramp starts, the Digital Storage Processor Section starts digitizing the ramp, and the front
panel SWEEP LED lights indicating a sweep is in progress.

Overall Troubleshooting
Triggered Sweep
The triggered sweep modes are very similar to free run operation except that instead of the
Al5 Controller outputting a set HSWP command to the
A3Al
Trigger assembly, it outputs a
trigger enable command. The output of the trigger select circuit (line, external, or video) then
clocks the HSWP line high.
Single Sweep
The single sweep mode is useful in troubleshooting the sweep system because it does not rely
on feedback from Digital Storage before resetting the sweep generator. Whenever the SWEEP
(ZiK$
key is pressed, the Al5 Controller resets the sweep generator and then sets HSWP
high through the
A3Al
Trigger assembly. Digital Storage then stops the sweep when it has
reached the end and the ramp resets to 0 V.
Fast Sweep
Fast sweep is enabled only for 0 Hz frequency spans and sweep times less than 20 ms. HSWP
is forced low, and the Al6 Sweep Generator is not used. See
A3Al
Trigger for a description of
the fast sweep operation.
Service Requests
Any of the Service Requests on the Al2 Front-Panel Interface will force LSRQ low which
forces HSWP low. For example, when a front-panel key is depressed, a keyboard Service
Request is generated. LSRQ goes low, LSTP goes high, and HSWP goes low stopping the
sweep. Depending on which key was pressed, the Al5 Controller will either continue the
sweep or reset it and start a new sweep. Note that the analyzer cannot sweep if any Service
Requests are present.
Sweep System Troubleshooting
The following procedure is an aid to rapidly isolate sweep system malfunctions. When the
malfunction has been traced to a single assembly, check the Service Sheets for that assembly
for a more thorough troubleshooting procedure.
Isolate the Scan Sweep
Disconnect the ramp from
A3A8Jl
and jumper
A3A8TPl
to
A3A8TP2.
This forces the ramp
comparator output high. The Digital Storage Processor Section should continue to process
data and increment the sweep address. The HSWP light should be flashing and HSWP should
have an approximately 16 ms pulse width. (Note that the instrument preset state may appear
to be functioning properly but will become distorted as the sweep time is slowed down.)
If this works, the Digital Storage Processor Section and Al5 Controller, Al2 Front-Panel
Interface, and
A3Al
Trigger assemblies are operating properly. Suspect the ramp generator
or Al6 Scan Generator or ramp converter on the A3A8 Analog-Digital Converter. To further
isolate the scan generator, reconnect the sweep ramp to
A3A8Jl
and remove the jumper. Set
the sweep time to 1 second and press the SWEEP
(ZiKZiY]
key. The ramp waveform will start
at greater than 10 V, go to 0 V when the SWEEP
[SINGLE]
key is pressed, and ramp back
Overall Troubleshooting
11
up to greater than 10 V. If the ramp waveform is correct, check the A3A8 ramp converter.
Otherwise check the ramp generator on A16.
Isolate Digital Storage Processor Section If HSWP Stays High (SWEEP LED ON)
With the sweep ramp disconnected from
A3A8Jl
and
A3A8TPl
jumpered
to
A3A8TP2,
check RSHS output for the presence of 60 ns low pulses. (The logic probe of the HP 5005A
Signature Analyzer can be used to detect them.) If present, check
A3Al
Trigger. If not, check
the Digital Storage Processor Section.
See
A3Al
Trigger Troubleshooting Procedure
Note that the
A3Al
Trigger assembly also generates and controls the fast sweep timing
(sweeps less than 10 ms).

Phase Lock Loops Principles of Operation
General Description
The fundamental RF signal input to the A6 RF Module (2 to 6.2 GHz) is generated by the
AllA
YTO (YIG-Tuned Oscillator). This signal is phase-locked, through other phase-lock
loops, to the A22 10 MHz Standard (internal crystal oscillator). The YTO Loop pretunes and
locks the YTO signal to the output of the M/N Loop (part of A7) and the A10
20/30
Loop.
The M/N and
20/30
Loops serve two basic functions. First, they phase-lock the YTO Loop
to the 10 MHz Standard through the Reference Loop (part of A7). They also provide the
stepped tuning of the YTO output signal. The M/N Loop provides the larger steps (2000 to
6199 MHz in 10 MHz steps) while the
20/30
Loop provides the smaller (1 MHz to 1 Hz) steps.
All phase lock loops are referenced, either directly or indirectly, to the A22 10 MHz Standard.
Figure 1. shows the relationship between the various loops as well as defining the assemblies
associated with the loops.

Analog Troubleshooting 1
Reference Loop (Part of A7)
The Reference Loop is phase-locked to the A22 10 MHz Standard and its phase-locked
outputs (10, 20, 100, and 400 MHz) are used as references for the
20/30
Loop, the M/N
Loop, and the Heterodyne Loop (part of A6). The 10 MHz signal is also used as an auxiliary
rear-panel output.
The A7A2 100 MHz VCXO (Voltage-Controlled Crystal Oscillator) is the heart of this loop.
The 100 MHz output signal is 1) routed to the A6A9 Phase Lock assembly to be used as a
reference for the Heterodyne Loop and as the front-panel CAL OUTPUT signal, 2) routed
to the AlOA3 PLL3 Up Converter to be used as a reference for that phase-lock loop, 3)
multiplied by four to produce the reference signal for the M/N Loop (A7A3 M/N Phase
Detector), and 4) divided by five to produce a 20 MHz reference signal also used by the
M/
N Loop. The 20 MHz signal is divided by two to produce a 10 MHz signal which is used
as a reference for the
PLLl
and PLL2 phase-lock loops in the
20/30
Loop and also as the
rear-panel auxiliary output. The 10 MHz signal is also phase compared to the output of the
A22 10 MHz Standard. The resulting error signal is used to tune the 100 MHz VCXO to
phase-lock the Reference Loop.
M/N Loop (Part of A7)
The frequency output of the M/N Loop is dependent on the front-panel Start
Frequency/Center Frequency and in part, controls the YTO output frequency. This signal is
disabled during sweeps when the frequency span is greater than 5 MHz (fundamental mixing).
An encoded equivalent of the front-panel frequency’s most significant digits are input to the
M/N Loop as M and N numbers. The ratio of the M and N numbers determines the M/N
OUT
(fM,N)
frequency and are chosen such that the Nth harmonic (same as the divider
number) of
fM/N
tunes in exactly 10 MHz increments as M is changed. There is one 10 MHz
step for each valid
fM/N
frequency (M/N ratio) and Nth harmonic (N number). Refer to Table
2 for a complete list of M and N numbers and resulting
fM/N
frequencies. This 10 MHz step
complements the
20/30
Loop whose tuning range is 10 MHz and step size is 1 Hz. Together,
the M/N loop, YTO pretuning, and
20/30
Loop are able to tune the
AllA
YTO from
2000.000 000 to 6199.999 999 MHz in 1 Hz steps.
YTO Loop (All)
Whenever a change is made to the Start Frequency/Center Frequency (from the front panel
or remote controller), the YTO is pretuned near the desired new frequency. This is done
by encoded information being sent from the Al2 Front-Panel Interface to the A19 DAC
(Digital-to-Analog Converter) which generates and routes an analog voltage to the A20 Main
Coil Driver. The Main Coil Driver, in turn, generates a tuning current to tune the YTO. This
places the YTO frequency 20 to 30 MHz below the Nth harmonic of the M/N Loop output
(fM,N).
For frequency spans greater than 5 MHz, the YTO frequency is locked at the start
of each sweep with the M/N loop and the
20/30
loop to a 1 Hz resolution. The YTO signal
(fYTO)
and the M/N Loop output signal
(fM,N)
are mixed in the
AllA
Sampler (harmonic
mixer) to produce the YTO IF (f
YT~JIF)
signal. This 20 to 30 MHz signal is phase compared
to the
20/30
Loop output signal
(f2e,ao)
in the
AllA
YTO Phase Detector producing a dc
error voltage. It should be noted that
fYTC)IF
and
fze/se
are equal when the YTO Loop is
phase-locked. This error voltage is stored in a capacitor, the loop (YTO) opened, and a sweep
taken. The loop is relocked at the start of each sweep. If the frequency span is less than 5
MHz, the YTO Loop is always locked and is forced to sweep by following the swept oscillator
2 Analog Troubleshooting
reference (fzoise) from PLL2 in the
20/30
Loop which is either applied directly to the YTO or
divided down and summed into PLL2 and
PLLl
and then applied to the YTO.
When the frequency span is less than 25 kHz, the loop gain of the YTO Loop is increased
by approximately 10 dB to provide better performance. This is performed by control signal
HYGH (High = YTO Loop
G
ain
High) being placed in a High state.
20/30
Loop
(AlO)
The
20/30
Loop translates tuning data for the seven least significant digits of the YTO
frequency (2 to 6.2 GHz) into frequencies from 30 to 20.000 001 MHz. This translation is
quite straightforward and the resulting output frequency can be calculated by the following
equation:
f2c,/ao=
30
-
xxxx
xxx MHz
where
xxxx
xxx is the seven least significant digits of the YTO frequency.
This process of frequency translation is used to tune the YTO over a 10 MHz range in 1 Hz
steps (1 Hz steps in zero frequency span) and uses three complete phase-lock loops
(PLLl,
PLL2, and PLLS) to achieve this.
Phase Lock Loop 2 (PLL2)
p
rovides a low-frequency (20 to 30 MHz) reference (fze,se) to
the YTO Loop for frequency spans between approximately 100 kHz and 5 kHz. This loop is
locked at the start of each sweep, the error voltage stored in a capacitor, the loop unlocked,
and a sweep taken. For frequency spans of less than approximately 100 kHz and greater
than 5 kHz, the 20 to 30 MHz output is divided by 5 and applied as an input to Phase Lock
Loop 3
(PLLS)
and Phase Lock Loop 1
(PLLl).
The output of
PLLl/PLLS
then serves as
the reference input
(f20,30)
to the YTO Loop. If the frequency span is 5 kHz or smaller, the
output of PLL2 is divided by 100 and applied to PLL3.
Heterodyne Loop (Part of A6)
The Heterodyne Loop (A6A9) consists of a 3.3 GHz oscillator located in the A6A4 Second
Converter that is locked to the 100 MHz VCXO in the A7A2 assembly. The 100 MHz
signal drives the Sampler in the A6A9 Phase Lock assembly which produces a dc output
proportional to the phase difference between the 33rd harmonic of 100 MHz and the 3.3 GHz
oscillator output signal being sampled. This dc output is amplified and used to drive the 3.3
GHz oscillator to achieve phase lock. If the loop is unlocked, a search oscillator (in the A6A9)
turns on and sweeps the 3.3 GHz VCO until phase-lock is again achieved. The Heterodyne
loop is used only for start frequencies of less than 2 GHz.

Start Frequency Tuning Equations and Phase Lock Troubleshooting
General
Phase-lock loop troubleshooting is much easier if it is understood how the start frequency
is derived. The Diagnostic Functions of the spectrum analyzer can also be used to simplify
troubleshooting of the phase-lock loop.
The simplified block diagram at the back of this chapter shows the assemblies involved in
setting the start frequency. The HP 8566B has two tuning modes. For frequency spans
greater than 5 MHz, a method called lock and roll is used. This basically involves phase
locking the analyzer start frequency during the retrace period prior to the beginning of a new
scan. For frequency spans of 5 MHz and less, the YTO Loop is phase-locked during all of a
sweep, and the stable
20/30
Loop PLL2 is swept.

M/N Loop Tuning
The frequency output of the M/N Loop is dependent on the ratio of M and N numbers. These
numbers are input in the form of digital tuning information to the M/N Loop Phase Detector.

numbers.

and the YTO frequencies, refer to Table 2, M and N Numbers and Resulting
Frequencies.
20/30
Synthesizer Tuning
When a start frequency change occurs, the YTO is pretuned near the new desired frequency
by the A19 Digital-Analog Converter and A20 Main Coil Driver. This places the YTO
frequency 20 to 30 MHz below the Nth harmonic of the M/N Loop output. (The Nth
harmonic is the same as the M/N Loop’s N number.) The YTO frequency and the M/N Loop
harmonic are mixed in the
AllA
Sampler. The YTO IF
(20-
30 MHz) is phase compared
with the
20/30
Synthesizer output. The
AllA
Phase Detector’s error voltage is then used
to tune the YTO through the A21 FM Coil Driver and the A20 Main Coil Driver to achieve
phase-lock.
The
20/30
Synthesizer is used to pretune the YTO in 1 Hz steps (in zero frequency span)
through a 10 MHz range. The following formula expresses the relationship between the
frequencies found in the YTO Loop.

knowing that the display consists of 1000 points and the programmed frequency span, the
processor calculates the offset between the center frequency and the marker. The frequency
span accuracy is the major cause of error in the readout accuracy of the MARKER

mode.
6 Analog Troubleshooting
Phase Lock Loop Troubleshooting
If one of the phase-lock error messages appears, a loop has failed. Start the troubleshooting
procedure by determining if the malfunction is dependent on Center Frequency, Frequency
Span, etc. Next, break the suspected loop and measure the power levels as indicated on the
RF Section Analog Block Diagram. Even with the oscillators at the extremes of their ranges,
the power levels must be within the limits indicated. The loop frequencies can be counted and
compared with the programmed frequencies listed by KSR by inserting a tee connector into
the loop.
The Lock Indicator Disable jumper
(A12TP2
to
A12TP3)
may be necessary if the keyboard
is locked out. Use the information from the Diagnostic Function and the Start Frequency
Tuning Equations to narrow the fault to a single assembly.

Preliminary Checks
Instrument Preset Check
The two red INSTR CHECK
LEDs
light whenever the instrument is turned on or when
@Z-Z@
is pushed. The main processor then performs a check of itself, a checksum
verification of all ROMs on the Al5 Controller, a partial check of the Instrument Bus (50-wire
bus), and a read-write check of the
RAMS
and A3A4 Memory in the IF-Display Section.
If all the checks pass, both INSTR CHECK LEDs turn off.
If any check fails, one or both INSTR CHECK LEDs remain on.
Both INSTR CHECK LEDs on indicates a problem with the Al5 Controller. First, remove
the Controller and make sure that the 50-wire ribbon cable and HP-IB ribbon cable are
pressed all the way onto
A15Jl
and A15J2 connectors. Reinstall the Al5 Controller. If both
front panel INSTR CHECK LEDs still remain on when the instrument is turned on, follow
procedure under Al5 Controller Self Test.
Left LED (INSTR CHECK I) on indicates a failure occurred when checking the Digital
Storage Memory (A3A4). First, check to ensure that a LINE power cord is connected to the
IF-Display Section. Also check to see that the rear-panel Analyzer Bus Interconnect Cable,
W31, is properly connected. If INSTR CHECK I still remains on when the instrument is
turned on, troubleshoot the A3 Digital Storage in the IF-Display Section.
Right LED (INSTR CHECK II) on indicates a failure occurred during the partial check of
the Instrument Bus.
Note The partial interface check reads the key column lines (KC0 through KC7)
from the Al and A5 front panels. If any front panel key is shorted or stuck
closed, INSTR CHECK II LED should remain on after the Self Test is
completed. This part of the Self Test can easily be verified by pushing any
key, except
CLCL),
and holding the key in while pushing
(2-22).
If the I/O
interface check routine is working, INSTR CHECK II LED will stay on.
n Suspected digital failure but no INSTR CHECK LEDs on may indicate a RAM or I/O bus
failure which is not checked in the normal Self Check or “POP” (Power-On Preset). If the
two front panel INSTR CHECK LEDs turn on when the LINE switch is set to ON, and
turn off again within a few seconds (indicating no digital problems), but symptoms persist
(such as improper CRT display or improper response to particular commands) indicating
that the problem is in the digital area, a “LONG POP” can be performed.
Digital Troubleshooting 1
“LONG
POP”
Instrument Preset Check
This check is very similar to the normal Instrument Preset Check: an additional processor
check is performed, all of the RAM locations in Digital Storage (A3A4 Memory) are checked,
and the RAM memory on the Al5 Controller is verified.
Since these more extensive checks require altering information that has been stored in RAM,
LONG POP requires an internal jumper on the Al5 Controller. To perform a LONG POP:
n Set the LINE switch to STANDBY.
w
Place a jumper between ST or STS to T3
q On Al5 Controller (HP part number 85660-60209) jumper
A15TP4
(STS) to
A15TPl-7
PO
q On Al5 Controller (HP part number 85660-60245) jumper
A15TPl-9
(ST) to
A15TPl-8
P-3).
q (Refer to Al5 Controller Component Location Diagrams for location of test points).
n Set the LINE switch to ON.
When LINE switch is set to ON, the two red INSTR CHECK
LEDs
are forced on and the
main processor steps through the Self Test routine, expanding the normal POP with the
additional tests mentioned above. The expected results for a LONG POP are exactly the
same as for the normal POP of Instrument Preset as described above in the Instrument Preset
Check.
Because LONG POP is a “destructive test” (it alters any information that has been stored in
RAM), it should be performed only as a last resort effort in troubleshooting what appears to
be a memory or processor related problem.
Digital Storage Verification
The Instrument Preset Check does a fairly complete verification of the Digital Storage
controller and memory. An additional check can be done, independent of the RF section, by
jumpering
A3A6TP3
to
A3A6TP6
and pushing
A3A7Sl
momentarily. A test pattern should
appear on the display. Refer to the A3 Digital Storage Troubleshooting Section in the HP
856628 IF-Display Section volume of the service manual for a more detailed description of
this procedure. Note that when the jumper is connected, the left check LED always stays
on following an INSTR PRESET, since in the test pattern mode, Digital Storage ignores all
instructions from the Al5 Controller.

The A5 Front Panel comprises the
A5Al
Keyboard, A5A2 Rotary Pulse Generator (RPG),
Instrument Check indicator
LEDs,
LINE power switch, STANDBY power indicator LED, and
CAL OUTPUT connector and cable. The RF INPUT, 1ST LO OUTPUT, and 321.4 MHz

described in detail in that section.
A5Al
Keyboard
A5Al
Keyboard includes the 49 pushbutton switches and 9 associated indicator
LEDs
on the
RF Section front panel.
Keyboard Switches
@
Each of the normally open SPST switches consists of a spring-loaded contact and a pair
of printed-circuit board contacts. All but two of the keyboard switches are organized in a
matrix of rows and columns. When a front-panel key is pressed, the corresponding SPST
switch is closed, connecting a normally grounded key row to a key column. The grounded
key column signal is detected on the Al2 Front Panel Interface,
signalling
the Al5 Controller
to immediately halt the sweep. Then, the Al5 Controller polls (grounds) each of the key
rows sequentially (starting with key row 0) to identify the particular front panel key that is
pressed. During normal operation, the front-panel SWEEP LED can be observed to blink off
momentarily as the Al5 Controller halts the sweep, polls both the IF Section keyboard and
the RF Section keyboard, and then reacquires phaselock before continuing on with the sweep.
Indicator
LEDs
@
The nine keyboard indicator LEDs and the two INSTR CHECK indicator LEDs are lighted
selectively by the Al5 Controller to indicate the state of coupled functions, SIGNAL TRACK
(on/off), DATA entry (enabled/disabled), HP-IB control status (remote and addressed), and
self-test. U2 and U3 latch the LED data from the Data Bus. All front-panel LEDs are lighted
momentarily during the turn-on self test for verification.
The two INSTR CHECK indicator LEDs are lighted selectively by the Al5 Controller to
indicate the overall results of the most recent instrument self test. An instrument self test is
performed each time the LINE switch is switched to ON or the
(INSTR
PRESET] key is pressed.
Both
LEDs
are lighted at the start of each self test, and both are turned off upon successful
test completion; if one or both of the INSTR CHECK LEDs remain on, an instrument fault
has been detected. Refer to the Al5 Controller section for detailed information about the self
test.
A5 1
A5A2
Rotary Pulse Generator
@J
A5A2 Rotary Pulse Generator (RPG) is operated by turning the front-panel DATA knob
in either direction. The rate and direction of knob rotation are encoded in the number
and relative phase of output pulses on the
RPGl
and RPG2 lines. These two signals are
decoded on the Al2 Front Panel Interface, enabling the Al5 Controller to gradually change
appropriate instrument settings.
LINE Power Switch
@
When the LINE switch is in STANDBY, the LSBY
(Low=STANDBY)
line is grounded. If the
RF Section is connected to an ac power source, the
+22
V dc supply lights the STANDBY
LED, holds the
A23Kl
Fan Relay in the off state, and powers the heater circuit of the A22A2
10 MHz Quartz Crystal Oscillator; all other power supplies are turned off. When the LINE
switch is switched ON, the
A23Kl
Fan relay is released to the on state (switching on the fan)
and LSBY rises to about
+22
V dc (due to the Fan Relay coil). This enables the
+20
V dc
supply on the Al7 Positive Regulator, which causes all the power supplies to turn on.
Front Panel Removal and Repair
With ac line cords removed, proceed as follows.
1. Remove interconnecting cables between instruments.
2. Position instrument on right side as shown in view A of Figure 1.
3. Remove feet

Caution
9
The YIG-Tuned Mixer (YTX) contains an extremely small and sensitive
diode. A reverse voltage in excess of 3 volts may damage it. It is connected
directly to the center conductor of the LO/IF connector, and is especially
susceptible to blowout from electrostatic discharge. Before connecting any
cable to this connector, first discharge the cable by connecting the center
conductor to ground. It is recommended that the other end of the cable be
connected first. Once the cable is properly installed (from the YTX to the
ACLU), the BIAS pin of the ACLU is connected to the YTX diode and must
also be treated with caution. A general rule is to connect all devices to ground
before connecting them to the BIAS pin on the ACLU.
22. Reconnect cable to A6A8 YTX.
23. Reconnect cable to
A6Al
RF Switch.

A6A3 Last Converter, Circuit Description
The Last Converter has three main purposes:
1. Converting the 321.4 MHz IF signal from the A6 RF Module down to 21.4 MHz for
processing by the IF-Display Section.
2. Providing the means for correcting for variations in conversion loss versus frequency in the
input circuitry.
3. Filtering out 278.6 MHz image response.
The Last Converter consists of 11 basic elements. They are a 321.4 MHz amplifier, a 321.4
MHz
bandpass
filter, a 321.4 to 21.4 MHz converter a 21.4 MHz preamp, two pin diode
attenuators, two pin diode controlled variable gain amplifiers, an output stage, a temperature
compensation circuit, and power supply filtering.
Power Supplies
@
The power supply filtering consists of series inductors and shunt capacitors (L21 to L24
and C49 to C53). In addition to this, R38 and
VRl
provide a 6.2 V source used for biasing
transistors.
321.4 MHz Amplifier
@
The 321.4 MHz amplifier consists of Q8 and its associated circuitry. Q7 provides bias for
QS
by setting the base current.
321.4 MHz Bandpass Filter
@
The 321.4 MHz amplifier drives the 321.4 MHz
bandpass
filter which consists of L4 to L8
and C8 to C12. This filter is made up of five LC tank circuits coupled magnetically and
capacitively. Capacitive coupling occurs through PC board traces on the circuit side of the PC
board. Coupling into and out of the filter is done with tapped inductors L4 and L8. The filter
is tuned by means of C8 to C12. This filter rejects the 278.6 MHz image response.
321.4 to 21.4 MHz Converter
@
The 321.4 MHz filter drives the 321.4 to 21.4 MHz converter. This converter consists of a
packaged double-balanced mixer,
Ul.
The 300 MHz LO for this converter comes from the
A6A9 Phase Lock.
A6A3
1
21.4 MHz Preamplifier
0
The 321.4 to 21.4 MHz converter drives the 21.4 MHz preamp which consists of Q6 and
its associated components. Q5 provides bias for Q6 by setting the base current. LlO, C22,
and C23 form a series resonant circuit producing a notch in the frequency response of this
amplifier at 10.7 MHz. This is to prevent the second harmonic of 10.7 MHz from causing a
spurious response.
Slope Attenuator
@
The HP 8566 is a harmonic mixing spectrum analyzer, and as such has five bands of
frequencies to cover the range of 0 to 22 GHz. When changing from band to band, the
conversion loss of the input mixer changes. Also within each band there are variations of
conversion loss with frequency.
The variations of conversion loss within each band are compensated by pin diodes CR1 to
CR4 and associated circuitry. Pin diodes have a property of changing RF impedance as
their dc current is varied. Thus
CRl/CR2
and
CR3/CR4
form the two elements of a voltage
divider. The current through
CRl/CR2
is fixed by RlO and
Rll.
The current through
CR3/CR4
is determined by circuitry on the
A6All
Slope Generator. This forms a current
controlled variable attenuator. Pin diodes
CRl/CR2
are used in place of a fixed resistor to
provide temperature tracking with
CR3/CR4.
Step Gain Amplifier 1
@
and Step Gain Amplifier 2
@)
The variations of conversion loss from band to band are compensated for by two identical
variable gain amplifiers made up of Q3 and
QlO
and associated circuitry (Q4 and
Q9
are
emitter follower buffers). A simplified circuit of one of these stages is shown in Figure 1. The
gain of the amplifier is determined approximately by the following equation.
Gain
M
Impedance (CR8, CR9, and CRlO)
Impedance (CR5, CR6, and CR7)
The impedance of CR8, CR9, and CR10 is determined by R23 and temperature compensation
circuitry
(Ql).
The impedance of CR5, CR6, and CR7 is determined by the current from the step gain circuit
on the A6AlO Relay Driver.
2
A6A3
Q
OUT
Figure 1. Step Gain Amplifier, Simplified Schematic
Amplitude Calibration Attenuator
@
Q2 is an emitter follower buffer driving a second pin diode attenuator, CR11 to CR14. The
current through CR11 and CR12 is determined by the front-panel control A6R1, AMPTD
CAL. The current through CR13 and CR14 is fixed by R27. This circuit provides for
amplitude calibration of the instrument.
21.4 MHz Output
@
Qll
and Q12 form the output stage for the Last Converter.
Qll
is an emitter follower driving
a common emitter amplifier Q12.
Temperature Compensation Voltage Source
@
Ql
provides a voltage to set the current in CR8 to CR10 and CR15 to CR17. This voltage
varies with temperature, changing the gain of the two step-gain amplifiers to compensate for
gain changes with temperature elsewhere in the Last Converter.

A6A7 YIG-Tuned Mixer (YTX) Current Driver, Circuit Description
The YTX Current Driver has three functions:
1. Provides the output stage for the A6A8 YTX coil.
2. Provides filter circuitry for the YTX.
3. Provides control circuitry for the YTX heater.
YTX Drive Output
@
The YTX drive output consists of Q5,
QS,
R14 to R17, VR4, and CR3. Q5 and Q6 form a
darlington transistor driven by the A6A12 YTX Driver. R14 to R17 are four 1000 ten-watt
resistors connected in parallel to form a 25R resistor which is used to sense the current in
the YTX coil. This sense signal is fed back to the YTX Driver. Four resistors are used for
power handling capability and temperature stability. VR4 and CR3 limit the flyback voltage
produced across the YTX coil during scan reset and prevent breakdown of Q5 and Q6.
Filter Capacitor Drive
@
When the spectrum analyzer is set to narrow spans and narrow resolution bandwidth, hum
and noise in the YTX drive circuitry which FMs the YTX can introduce phase noise and
line frequency sidebands onto a displayed signal. To prevent this occurrence, a large filter
capacitor, A6A7C1, is connected across the YTX coil by switch
QS
whenever the resolution
bandwidth is 100 Hz or less.
QS
is controlled from
A6All
Slope Generator through Q2, Q3, and Q4. When the resolution
bandwidth is 100 Hz or less, the filter capacitor is connected before the start of a scan and
disconnected at the end of a scan so that the scan reset and hysteresis correction can be
performed.
YTX Heater Control
@
The YTX heater control is a feedback circuit designed to maintain the center support of the
YTX at a constant 75”C, as the ambient temperature ranges from 0“ to 55°C. The green
LED,
DSl,
indicates that current is flowing properly in the heater. Red LED, DS2, indicates
the circuit is saturated, putting maximum power into the heater.
The heater ring of the YTX has a
4500
thin-film heater resistor, and a thermal sensor with
a positive temperature coefficient. The resistance versus temperature characteristics of the
thermal sensor are shown in Figure 1.

Ql,
and Q7 f
arms
an amplifier with a gain of about 127. In
addition, R2 and R3 set a reference voltage at the negative input of the amplifier. Darlington
Ql
and Q7 is able to provide the large currents required to heat the heater resistor to 75°C.
VR2 and R5 offset the op-amp output voltage to be within range of the output stage (0 to
-40 V). CR1 protects the op-amp input.
The circuit operates as follows: If the heater ring is cool (such as at turn-on), the divider
formed by
Rl
and the sensor (described above) outputs a voltage that is less than the
reference at the minus input to the amplifier. This causes the amplifier output to swing
negative, thus drawing more current through the heater resistor, heating up the sensor,
causing it to increase its resistance. This raises the voltage at the
Rl/sensor
divider output
until it exactly equals that of the reference divider
R2/R3.
In general, small temperature
errors are manifested as a small voltage between pins 2 and 3 of the op-amp (its input). This
error is amplified and applied to the heater resistor with the appropriate sign to eliminate the
error.

A6A7/A6A5/A6A8
A6A8 YIG-Tuned Mixer (YTX),
A6A5 Amplifier/Coupler/Load Unit (ACLU), Circuit Description
The YTX consists of a three-pole tunable
bandpass
filter and a single-diode microwave
harmonic mixer. The 2 to 6 GHz local oscillator (LO) signal enters the ACLU, and is
amplified and coupled into the YTX to turn its diode on and off at the LO rate. The diode
conduction angle is adjusted with DC diode bias to be optimum for the harmonic of the LO
being used. The incoming microwave signal passes through the
bandpass
filter, through the
mixer diode, as the diode switches on and off, and into the precision
500
load of the ACLU.
The IF signal at 321.4 MHz travels down the same line as the higher frequency LO, but a
matching network couples the 321.4 MHz IF signal to the ACLU output while blocking the
LO.
The three-pole filter has two purposes:
1. To reject the image response of the mixer 642.8 MHz away from the desired signal.
2. To reject the LO signal that would otherwise come out of the mixer’s microwave input
port, and out of the instrument front panel.
Handling the YIG-Tuned Mixer
Caution
The YIG-Tuned Mixer (YTX) contains an extremely small and sensitive
diode. A reverse voltage in excess of 3 V may damage it. It is connected
directly to the center conductor of the LO/IF connector, and is especially
susceptible to blowout from electrostatic discharge. Before connecting any
coaxial cable to the YTX, connect the YTX BIAS pin to ground, discharge
the coaxial cable by connecting the center conductor to ground (YTX body),
then simultaneously touch both to chassis ground or the YTX package. It is
recommended that the other end of the cable be connected first before going
through this procedure.
Once the cable from the YTX to the ACLU is properly installed, the BIAS pin
of the ACLU is directly connected to the YTX diode. Therefore, treat the
BIAS pin with extreme caution, especially avoiding electrostatic discharge.
As a general rule, connect all devices to the chassis before connecting to or
touching the BIAS pin on the ACLU.

Phase Lock, Circuit Description
The A6A9 Phase Lock has three major functions:
1. To provide a stable -10.0
dBm,
100 MHz calibrator signal to the RF Section front panel.
2. To provide a 300 MHz local oscillator to the A6A3 Last Converter assembly.
3. To phase-lock the 3.3 GHz second local oscillator in the A6A4 Second Converter assembly
to the 33rd harmonic of the 100 MHz reference signal produced by the A7A2 100 MHz
VCXO assembly. This 3.3 GHz phase lock loop is called the Heterodyne Loop.
100 MHz Buffer Amplifier
@
The 100 MHz buffer amplifier
Ql
amplifies the reference signal from the A7A2 100 MHz
VCXO assembly. Low pass matching network,
Ll
and C4, provides a
5Ofl
input impedance.
Transformer
Tl
acts as a power divider, supplying the 100 MHz signal to both the Driver
circuit and the Phase Lock circuit.
Driver
@
Transistor Q2 amplifies the 100 MHz from the 100 MHz Buffer Amplifier. Power divider T2
drives both the 100 MHz Calibrator and the 300 MHz LO circuit.
100 MHz Calibrator
@
The Calibrator circuit consists of a differential amplifier, Q3A and Q3B, followed by a low
pass filter. Low pass filters C19, L8, C20,
L9,
and C22, reduce higher order harmonics on the
front panel calibrator output. Potentiometer
Rll
and factory-select resistor RlO set the gain
of Q3.
Tripler
@
With the 100 MHz input from the Driver circuit, the Tripler circuit produces a 300 MHz
output at approximately
+6
dBm.
Inductor
LlO
and C24 are used for impedance matching.
The output tank circuit, formed by
Lll
and the output capacitance of transistor Q4, resonates
at 300 MHz. Capacitor C29 adjusts the loading of the stage and couples the output to the
Power Amplifier.
A6A9
1
300 MHz Power Amplifier
@I
The output of the 300 MHz Power Amplifier, approximately
+20
dbm, is the local oscillator
for the A6A3 Last Converter. Capacitor
C30
reduces the sub-harmonic content of the output.
The output filter C52, L21, and C53, reduces higher order harmonics while maintaining a
500
output impedance.
Sampler Driver
@I
Amplifier U2 drives the Sampler step-recovery diode (function block E) with the 100
MHz signal at a level of approximately
+20
dBm.
Capacitors C8, C9, and L4 match the
forward-biased impedance of the diode to U2. Resistor R5 loads the output of U2 during the
diode’s reverse biased condition.
Sampler
@
and Loop Integrator
@
The output of the sampler is a dc voltage proportional to the phase difference between the
33rd harmonic of the 100 MHz reference and the 3.3 GHz second local oscillator (A6A4
Second Converter). Integrator U3 supplies a tune voltage to the 3.3 GHz second local
oscillator. This heterodyne loop phase locks the oscillator to the 100 MHz reference signal.
Potentiometer R38 adjusts the output balance of the sampler. Capacitor C46 is the integrator
capacitor for U3.
Aided Acquisition and Unlock Detector
@
The output tune voltage from the Loop Integrator (function block F) becomes
-
25 V when
the 3.3 GHz Heterodyne Loop is unlocked. The Aided Acquisition circuitry detects this
condition and retunes the 3.3 GHZ oscillator on the A6A4 Second Converter assembly within
the capture range of the phase-lock loop. The Aided Acquisition circuitry also controls the
Lock Indicator (function block J).
The Negative Rail Detector U4A is an inverting comparator. The threshold voltage at pin 5 is
set at -23.5 V. During unlock, the input of U4A becomes more negative than the threshold
voltage and the comparator output becomes positive. Resistor R21 provides positive feedback,
stabilizing the circuit. Resistors R25 and R26 form a voltage divider reducing the input to
U4B
below the value of the power supplies. The positive output of U4A triggers One Shot
multivibrator U4B. The negative output of U4B forward biases diodes CR1 and CR2. The
diodes become a constant current source for integrator capacitor C46 (function block F),
causing a positive direction search ramp of voltage at the output of U3. This search ramp
tunes the 3.3 GHz second local oscillator through the capture range of the phase-lock loop.
If the phase-lock loop does not phase-lock on the search ramp, the tune voltage will remain
positive until the One Shot recovers, reverse biasing CR1 and CR2. The output of U3 then
becomes negative (unlock condition), causing the Aided Acquisition circuitry to repeat the
search cycle until phase-lock occurs. This results in a sawtooth tune waveform with a period
of approximately 6 ms.
The One Shot pulse width of approximately 1 ms is controlled by R24 and C38. This is the
time it takes for the voltage on pin 7 to decay to -25 V to less the -20 V. During this time,
the input to U4C has become -20 V due to the positive tune voltage ramp. In high band the
3.3 GHz second local oscillator is switched
off;
the PIN signal goes negative, which disables
the search ramp and unlock detector through CR3.
2
A6A9
Switch and Unlock Detector: When unlock occurs, the output of U4B becomes low, causing
U4C to have a low output. The output of U4D becomes positive, turning off Q5. If no lock
occurs on the search ramp, the delay caused by resistor R27 and capacitor C37 keeps
Q5
off
until the next search cycle begins. This delay is different for an HP 85660A RF Section, and is
set by the value of R27.

Miscellaneous Bias/Relay Driver, Circuit Description
This assembly is a collection of circuits necessary for proper operation of other assemblies in
the A6 RF Module. It contains nine circuits:
1. YTX Diode Bias
2. YTX Linearity Correction
3.
3.3 GHz Oscillator Driver
4. PIN Switch Driver
5. Band Step Gains
6. RF Switch Driver
7. RF Attenuator Driver
8. j-22 V Delay
9.
Power Down
YTX Diode Bias
@
To maintain the precise diode bias across the YTX mixer diode, the effects of series resistance
between the bias circuit and the diode must be eliminated. To do this, a negative impedance
voltage source U2 is used.
Voltage bias to the YTX diode is adjusted from band to band via R9, R12, R15, and R18.
This voltage is applied to U2 via FET switches
QS,
Q7,
QS,
and
&lo.
U2 has both positive
and negative feedback. The positive feedback is controlled by R43, R46, and R47, while the
negative feedback is via R45. The fact that the positive feedback and the negative feedback
are picked off across R44 causes a negative impedance at pin Pl-7 proportional to the
amplifier gain and R44.
YTX Linearity Correction
@I
Due to nonlinearities in the YTX magnet structure, some linearity correction must be made.
This is accomplished by placing resistors in parallel with the current-sense resistor in the
YTX coil driver circuit. These parallel resistors increase the coil current slightly. For current
compensation, both the point of compensation and the magnitude of compensation must be
varied.
This is accomplished in the following manner using U7D as a typical circuit: U7D is an ideal
zener circuit, that is, as long as the YTX linearity voltage is less negative than the voltage on
U7 pin 12 (the positive op amp input) diode CR5 is reverse biased. In this state, the YTX
linearity line sees a high impedance and no compensation occurs. When the YTX linearity
voltage goes more negative than the bias on U7 pin 12, diode CR5 is forward biased and U7D
A6AlO
1
becomes a voltage follower maintaining the voltage at the cathode of CR5 at the same voltage
as on U7 pin 12. In this situation, R32 and R31 are effectively in parallel with the current
sense resistor of the coil driver circuit. R31 is used to adjust the magnitude of compensation,
while R40 is used to adjust the frequency at which the compensation occurs. In a similar
manner, U7A, B, C are used to correct for higher frequency nonlinearity.
PIN Switch Driver
@
The PIN switch driver converts the TTL logic level LO-BAND signal to the $20
V/-10
V
signal required by the Second Converter. The TTL level at
Pl
to 34 is input to the base of
Q21.
A high at the base of Q21 turns Q21 on, turning on Q4, which pulls the collector of Q4
approximately
+20
V. This turns on Q3, providing the
+20
V signal to the PIN drive output,
Pl
to 35. A low input on the LO-BAND TTL input turns Q21 off, which turns Q4 off. The
collector of Q4 then goes low, turning on Q2, and pulling the PIN drive line to -10 V.
3.3
GHz
Oscillator Driver
@I
The PIN drive signal is also used to turn the 3.3 GHz oscillator on in A-Band, and off in other
bands. When the PIN drive goes high,
Ql
is turned on which pulls its collector to -10 V. The
-10 V is the negative bias for the 3.3 GHz oscillator. When the PIN drive goes low,
Ql
is
turned off, dropping the oscillator bias current to zero, which turns off the 3.3 GHz oscillator.
In the on state, resistor
Rl
is used to adjust the oscillator bias current to 15 milliamps.
RF Switch Driver
@
The coaxial RF switch is driven by darlington amplifiers U5E, and U5F. A high input on the
LO-BAND line drives the outputs of U5F low, and U5E high. A low output at U5F drives the
Coaxial RF switch relay to the A-Band (0 to 2.5 GHz) position. The reverse occurs with a
low input which drives U5E’s output low, which forces the coaxial RF switch relay to the B-E
Band (2 to 22 GHz) position.
Band Step Gains
@
To correct for different input mixer conversion efficiencies and gains in the individual
frequency bands, the IF gain is changed. This is done in the A6A3 Last Converter by varying
the current through PIN attenuator diodes in the 21.4 MHz amplifier. This current is
controlled by Q12, Q14 to Q17, and
Q19.
In A-Band, the high output on the PIN drive line
breaks down zener
VRl
and turns on
Ql2.
This applies -40 V to the potentiometer R21.
Adjusting R21 varies the current in the step gain in A-Band.
The gain of A6A3 Last Converter is adjusted in each band as each transistor,
Ql2,
Q14 to
Q17, and Q19, is turned on for each individual band.

RF Attenuator Driver
@
The RF attenuator driver is similar to the RF Switch driver. The major difference is the logic
decoding to the inputs of the darlington switch drivers. The input to the logic circuit is the
standard 10, 20, 40, dB attenuation logic levels. The logic circuit
Ul
decodes this to the 10,
20, 20, 20, dB attenuation logic levels required to drive the RF attenuator. The output drivers
consist of darlington amplifiers driven by the outputs of
Ul
or the inverted outputs of
Ul,
via
U3. A low output of a darlington turns that line on. That is, a low at U5D pin 13, coupled
with high at U4F pin 11, enables the 10 dB attenuation position, and so forth.
Power Down
@
The power down circuit switches the RF attenuator into a 40 dB attenuation position to
prevent accidental damage to A6A8 YTX or A6A6 First Converter from an input signal when
the instrument is off. When the power up signal goes low, U3 pin 10 is driven high which
turns on
Q9
and Q13, forcing
Ul
pins 5,6, and 9, U4 pin 7, and U3 pin 5 high. This forces at
least the last two 20 dB attenuation stages in the attenuator on.
+22 V Delay
@I
On power up, the instrument goes through a self-check program. To prevent the RF relays
and the attenuator from chattering during this time, the
+22
V Bias to the attenuator and
RF switch is delayed for about 2.5 seconds after the power up signal goes high. This delay is
caused by R59 and ClO. When power up goes high, it takes approximately 2.5 seconds for the
voltage across
Cl0
to charge up enough to turn on U3E. U3E output is inverted twice by the
darlington amplifiers U4B and U4A so that when U3E output drops, U4A output also drops
turning on
Qll
which applies the
+22
V to the relay circuits.

Slope Generator, Circuit Description
The slope generator takes a voltage which is proportional to YTX frequency and produces a
current to control the slope attenuator in the A6A3 Last Converter, which compensates for
conversion loss variations of the input mixer within each frequency band. The slope generator
also has circuitry which decodes bandswitch and attenuator settings, produces pulses for
the sample and hold, and hysteresis circuits in the A6A12 YTX Driver, produces the YTX
peaking signal for the YTX Driver, and a signal to switch in the filter capacitor on the A6A7
YTX Current Driver.
Bandswitch and Attenuator Decode
@
U9
is a hex latch which receives six lines from the 50-wire Instrument Bus and a strobe,
LCK2, which goes low when the six lines have valid A6 RF Module information. Three of
the latch outputs have attenuator setting information and go to the A6AlO Miscellaneous
Bias/Relay Driver. The other three lines have bandswitch information which is decoded by
U3A and U3B.
U3B
decodes the low band (Band A, 0 to 2.5 GHz) and the external mixer band (Band F).
When pin 2 of
U9
is high and pin 12 is low, Band A is selected. The output of
U3B
is high,
turning
Q22
on, bringing the collector of Q22 low. This turns
Q19
off, bringing the collector
of
Q19
(LO BAND) high. This information goes to the A6AlO Miscellaneous Bias/Relay
Driver to control the
A6Al
RF input switch. Q20 inverts the signal and drives amplifier A4A,
producing a signal which is approximately
+17
V when Band A is valid and approximately
-8 V otherwise. This signal is used throughout the
A6All
Slope Generator. When pins 2 and
12 of
U9
are both high, Band F is active. The output of
U3B
is low, turning
Q22
off, and
bringing the collector of
Q22
(and Band F line) high. At the same
time,me,
Q19
turns on,
bringing the LO BAND line low.
U3A decoder is enabled when pin 2 of
U9
is low. Pins 5 and 12 of
U9
have coded information
giving harmonic numbers as shown in Table 1.

This information is decoded by U3A and amplified by U5. The outputs of U5 are
approximatley
+3
V when a band is valid and approximatley -22 V otherwise. These signals
are used to drive FET switches on the
A6All
Slope Generator and the A6A12 YTX Driver.
Preselector Peak
@J
A second latch, UlO, receives the same six lines a U9, but receives a different strobe, LCK5.
This strobe is valid when the six lines have preselector peaking information. The outputs
of this latch drive eight bits of a DAC which produces 0 to 10 V at the output of
U4B
corresponding to DAC values of 0.00 to 63.75. This voltage goes to the A6A12 YTX Driver.
This circuit is used to adjust the tacking of the YTX when [PRESELECTOR PEAK) or
(SHIFT)
a),
(K)
(+dBm),
or
(SHIFT)
Ide]
is keyed in.
Hysteresis, Sample-Hold Control, and Filter Capacitor
@
U8 is a Quad D-Latch which is used to decode information relating to Hysteresis, Sample and
Hold, and Filter Capacitor information. Four lines from the 50-wire Instrument Bus go to the
inuts
of the latch. The latch is strobed when these lines have valid RF Module information.
The instrument controller is able to connect the filter capacitor across the YTX, and control
the Hysteresis and Sample and Hold circuits on the YTX Driver.
Slope Offset
@
U7 receives the -0.525
V/GHz
signal from the A6A12 YTX Driver, amplifies and offsets it
such that a
t1.83
V/GH
z ramp centered about 6 V is produced at TP8.
Qll
to Q15 and
associated circuitry produce the offset for each band, and R2 varies the A-Band offset to
position the A-Band slope breakpoints.
Slope Breakpoint Generator
@
The signal at TP8 has a maximum range on Band C (5.8 to 12.5 GHz, second harmonic)
of approximately 0 to 12 V. This signal is applied to two voltage dividers
R36/R37
and
R38/R39,
which drive the positive inputs to U6A and
U6B
respectively. The voltage at the
inputs to these op amps is clamped by CR5 and CR6 such that U6A sees only the first half
of the full band ramp and
U6B
sees only the second half. In this manner, each full band
is divided into two segments with one breakpoint in the center. Both U6A and
U6B
are
configured for a gain of 2 and an offset of approximately -6.2 V, for a 0 V output at
midband
and unity gain overall.
Upper Segment Generator
@
and Lower Segment Generator
@
The outputs of U6 drive variable gain amplifiers as shown in Figure 1.

Figure 1. Variable Gain Amplifier, Simplified Schematic
When the 20 K potentiometer is set to zero, the amplifier has a gain of
+1/2;
when set to
20 K, the gain is
-l/2;
and when set to 10 K, the gain is zero.
FETs
Ql
to
QlO
switch in
different 20 K potentiometers for the five bands. The outputs for the two segments at U2 are
summed together in
Ul.
A waveform similar to Figure 2 is present at the output of
U2B
if
a full band is swept (for example, 5.8 to 12.5 GHz), and the oscilloscope horizontal input is
connected to the sweep output of the analyzer. Similarly, the output of U2A will appear as
shown in Figure 3.
Slope Output
@I
Both waveforms (Figure 2 and Figure 3) are summed together at
Ul
to form a current source
with Q16 to drive the slope attenuator in the A6A3 Last Converter. The average output
current is set by slope gain adjustment R84.
The slope attenuator in the A6A3 Last Converter varies the gain of the 21.4 MHz IF with the
collector current of
Ql6
providing gain correction that varies with frequency. Within each
band, there is independent control over two halves of the band, and IF gain that increases or
decreases with increasing frequency.
When Band F (external mixer) is selected,
QlS
and
Q21
provide additional gain to make up
for the conversion loss of the external mixer.

A6A12 YIG-Tuned Mixer (YTX) Driver, Circuit Description
The YTX Driver receives a voltage proportional to the instrument LO frequency and produces
a signal to control current in the YTX coil.
Input Differential Amplifier
@
This input signal to the YTX Driver comes from the A19 DAC and is -3
V/GHz.
For
example, as the YTO Loop sweeps from 2 to 6 Ghz, this input signal sweeps from -6 to
-18 V. It is buffered by differential amplifier
UlA,
and appears at
TPl.
Bandswitch
@
The frequency that the YTX is tuned to must be made to follow the first, second, third,
or fourth harmonic of the YTO frequency, depending on the frequency band in which the
instrument is operating. This is done by attenuating the buffered input signal with a voltage
divider as shown in Figure 1.

Figure 1. Bandwidth Voltage Divider
The position on the attenuator is determined by the harmonic number in use. The
bandswitching is done with FET
Ql,
Q2, Q3, and
Q12.
The bandswitch information used to
turn on the
FETs
comes from
A6All
Slope Generator. R6 and
Rll
to R14 form a second
voltage divider used as a gate return through R15 to R18. This prevents current through
bandswitch diodes and resistors (for example,
R19
and
CRl)
when the associated FET is
switched off from affecting the bandswitch voltage divider R5 and R7 to RlO.
A6A12

Sample and Hold
@
The output of the bandswitch drives preamp U5. U5 and
UlB
together form an op amp with
U5 a low-noise, low-temperature drift preamplifier. U5,
UlB,
and U6 are used in a sample and
hold circuit as shown in Figure 2.
Q15, a JFET, is used as the switch for the sample and hold. The switch is opened (that is,
the FET is turned off) whenever a bandcrossing occurs. When a bandcrossing occurs, the
input voltage at
Jl
changes as the YTO Loop resets its frequency to start a new band, and
the YTX bandswitch changes bands. At this time, the voltage at the input of U5 varies.
The sample and hold circuit is used to prevent these variations from reaching the YTX.
The sample and hold switch is controlled through Q14 by a signal from the
A6All
Slope
Generator. R44, R45, CRlO, and CR11 keep the output of
UlB
from saturating when the
feedback loop is opened by Q15 being off. This prevents a “glitch” at the output of U6 when
the loop closes if
UlB
suddenly had to recover from a saturated condition.

IF Offsets
@
In addition to tracking a harmonic of the YTO, the YTX must be offset from this LO
harmonic by the first IF (321.4 MHz). This is done by U7A and its associated components.
Q7 to
QlO
switch in different IF offset adjustments for each band. The YTX peaking signal
from
A6All
Slope Generator is also summed into U7A through R77.
Sweep + Tune
@I
Since the U5,
UlB,
and U6 combination have a gain of 1.05 set by R48 and R75, the voltage
at TP5 has an sensitivity of -0.525
V/GHz
(YTX). Th
is
signal goes to the
A6All
Slope
Generator, to voltage divider R54 and R55, and to U8. U8 is set to give -1
V/GHz
at its
output which goes to J2. This signal is cabled to the rear panel of the instrument to provide
an analog voltage proportional to input frequency. U2A and its associated circuitry provide an
offset voltage for U8 to correct for the first IF (3.6214 GHz) in the 0 to 2.5 GHz band. R98 is
adjusted for 0 V at U2 with the spectrum analyzer tuned to 0 Hz.

YTX Drive Output
@
Voltage divider R54 and R55 drive the output stage shown in Figure 3.
R,
and the output transistor are on A6A7 YTX Current Driver. The YTX has a nominal coil
sensitivity of 75 MHz/mA. R63 and R66 provide the means for compensating for variations
amount
YTXs.
When the YTX center frequency is tuned to 5.8 GHz, the voltage at pin 3 of
U3 is
+1.52
V. There is no voltage across R66 so it has no effect. R63 is adjusted for tracking
at 5.8 GHz and R66 is adjusted at 2 Ghz. U4A and voltage divider R68 and R69 provide the
t1.52
V source.
The YTX magnet exhibits hysteresis which must be corrected for. This is done by signals
from the
A6All
Slope Generator which is controlled by the instrument controller.
QlS
is
turned on for a short period of time to correct for hysteresis in narrow spans
(<l
GHz);
QlS
and
Q19
are both turned on for a short period of time in large spans and when making large
downward steps in frequency. The length of time that the transistors are on and the length of
time after they are off before the sweep starts is controlled by the instrument controller and
varies with start frequency, span, previous stop frequency, and so on.

Figure 3. Output Amplifier, Simplified Schematic
Delay Compensation
@I
The YTX and YTO (LO) are electromagnetically tuned devices. As such, they both exhibit a
delay in their response to changes in magnet current. When a change in coil current occurs,
there is a delay before the corresponding change in frequency occurs. When a ramp of current
is applied to a YTX or YTO magnet coil, there is a time delay between the ramp current
and the corresponding frequency. Since the YTX and YTO have different magnet structures,
they exhibit different amounts of delay. This causes tracking problems. These problems are
compounded by harmonic mixing and heating effects.
On the fourth harmonic, the YTO is sweeping
l/4
as much in frequency as the YTX. Thus
the YTO exhibits its least delay with respect to the YTX. R24, R25, Cl, C2,
Cll,
and C23
are used to “speed up” the YTX to track the YTO on fourth harmonic. On lower harmonics,
the YTO exhibits more delay compared to the YTX since it must now sweep further. The
YTX is then delayed to match the YTO under these conditions by R26 and C3.
A6A12
3
Since these RC combinations have long time constants, they cannot readily respond to the
transients produced at band crossings and scan resets. Therefore, whenever the sample and
hold circuit is holding, R24 to R26 are shorted by Q4 to
QS
respectively.
+9 V and -9 V Reference Supplies
@I
U2B and
U7B
and their associated circuitry form -9 V and
+9
V reference supplies used in
the YTX Driver, and elsewhere in the A6 RF Module.

A7 M/N Reference, Troubleshooting
Reference
All phase lock loops in the HP 8566B are referenced to the A22 10 MHz Frequency Standard.
The 10 MHz Frequency Standard is used to directly phase-lock the A7A2 100 MHz VCXO
only. All other phase lock loops receive their reference from either the
A7Al
or A7A2 (10 and
20 MHz from the
A7Al
and 100 and 400 MHz from the A7A2).
A malfunction of the 100 MHz VCXO is indicated by all phase lock error messages
(PLl
UNLOCK,PL2UNLOCK,
REFUNLOCK, YTO UNLOCK,
M/NUNLOCK,
and
HETUNLOCK)
being
displayed on the HP 8566B CRT. Table 1 lists the phase lock error messages, related
reference, location for measurement, and signal level.

M/N Loop
The M/N Loop consists of a 355 to 395 MHz VCO, part of A7A4, and a phase detector, part
of A7A3. The output of the VCO is divided by two and is used to drive the
AllA
Sampler
assembly. This divided signal is disabled by means of control line LMNE during sweeps when
the frequency span is greater than 5 MHz (fundamental mixing). The two divider numbers, M
and N, are selected by the Al5 Controller such that the Nth harmonic (same as the N divide
number) of the divided VCO output changes in exactly 10 MHz increments as M is changed.
A7 1
For example:
If M = 26,
N = 20,
and VCO Frequency = 187.0 MHz,
then M/N output frequency = N (VCO) = 20 x 187.0 = 3,740 MHz.
If M is changed to 25,
then the VCO frequency changes to 187.5 MHz,
and the M/N output frequency changes to 3,750 MHz (20 x 187.5).
Result
=
10 MHz change for M divider change of 1.
An incorrect M or N number, due to the main controller or a bad latch on A7A3, can be
easily detected. The frequency diagnostic
(SHIFT)
MKR+
REF
LVL
gives the M and N numbers
and the M/N output frequency (VCO divided by two) for the start frequency selected. A
frequency counter attached to A7A4J2 indicates the actual frequency output. Table 2, “M
and N Numbers and Resulting Frequencies,” of the RF Section Analog Troubleshooting tab,
lists all possible M/N output frequencies. By locating the M/N frequency measured by the
counter, the M and N numbers required to produce this frequency are obtained. The M and
N numbers can then be compared to those shown in the frequency diagnostic. The latch
and divider for the number in error can then be located using the troubleshooting procedure
outline for A7A3.

Reference Phase Detector, Circuit Description
The
A7Al
Reference Phase Detector contains the frequency divider, phase detector, and
integrating amplifier for the 100 MHz Reference phase-lock loop. Basically, 100 MHz from
the A7A2 VCXO is divided by 10 and compared to the 10 MHz frequency reference by the
phase detector. The error voltage from this comparison is fed back to the VCXO to keep its
frequency locked to 10 times that of the frequency reference. The bandwidth of the reference
phase-lock loop is 100 Hz; the 10 MHz derived from the 100 MHz VCXO must be within 100
Hz of the 10 MHz frequency reference for the loop to lock reliably.
Limiting Amplifier
@
Ul
amplifies and limits the amplitude of the reference signal from the rear panel FREQ
REFERENCE input. For proper operation of the 100 MHz Reference phase-lock loop, this
signal should be 5 MHz
f25
Hz or 10 MHz
f50
Hz at a power level of 0
dBm
to
+lO
dBm.
The internal A22A2 10 MHz Quartz Crystal Oscillator provides a stable, high spectral purity
10 MHz frequency reference at a power level of at least
+7
dBm
at the rear panel FREQ
REFERENCE output. A short BNC jumper cable is normally connected between the FREQ
REFERENCE input and output jacks to route the internal frequency reference signal to
the 100 MHz Reference phase-lock loop. The spectral purity of the FREQ REFERENCE
input signal directly affects the instrument phase noise performance. The internal frequency
reference remains off during instrument warmup (from a cold start) until it reaches thermal
equilibrium.
Pulse Generator
@
U2D is biased with feedback resistor RlO to further limit the 10 MHz to a well-shaped square
wave and set the proper logic levels for digital buffer U2C. U2A and
U2B
generate narrow
pulses, the width being the gate delay of U2A plus the delay from
Rll
and C5. When the
output of U2C goes low, the output of
U2B
goes high after one gate delay (of U2B). After a
delay due to
Rll,
C5 and U2A gate delay, the output of U2A goes high which causes
U2B
output to return low again, thus generating a narrow pulse.
Phase Lock Sampler
@
The phase lock sampler performs the function of phase detector. The 10 MHz pulses from the
buffer amplifier are applied to the primary of
Tl
which causes CR3 and CR4 to turn on for
the duration of the pulses. This samples the divided by 10 VCXO frequency and stores this
voltage on C36. When the loop is locked, the feedback due to the complete phase-lock loop
forces this voltage to be nearly zero. When the loop is unlocked, this voltage may be zero or
varying, depending on the reason for unlock.
A7A1
1
Integrating Amplifier
@
Q4 is a differential input pair which together with
Q5
and Q6 forms a high gain amplifier.
Feedback is added with C32 and R49 to make an integrating amplifier. C32 provides ac
feedback only, so for the amplifier to remain linear, dc feedback is accomplished by virtue of
the entire phase-lock loop.
VCXO Divider and Buffers
@
100 MHz from the A7A2 VXCO is applied to the counter U3 which divides by 5, then by
2. Its outputs are 10 MHz and 20 MHz which are buffered by U4 to be used as reference
frequencies by other assemblies in the instrument. The other 10 MHz output is used to drive

Phase Lag and Buffer Amplifier
@
The 45’ phase shift buffers are used to provide two 10 MHz signals which are 90” apart in
phase, the purpose of which is explained in Lock Indicator Sampler description. 45” phase
shift in
@
is accomplished with C35 and R53, while in
@)
it is done by R59 and C38.
Lock Indicator Sampler
(ij
The lock indicator sampler functions the same as the phase lock sampler
0.
The only
difference is that the 10 MHz is 90” shifted in phase. This causes the output of the lock
indicator sampler to be maximum negative voltage when the loop is locked, since in this state
the output of the phase-lock sampler is 0 V.
Phase Lock Detector
@
The output of the lock indicator sampler is compared to -0.5 V by U5. When the output
voltage becomes closer to 0 than to -0.5 V, U5 switches its output to TTL high to indicate to
the Al5 Controller that the 100 mHz Reference phase-lock loop is unlocked.
During instrument warmup, the A22A2 10 MHz Quartz Crystal Oscillator remains off for a
few minutes until thermal equilibrium is reached. It is normal for both an OVEN COLD and
REF UNLOCK indication to appear on the CRT during these first few minutes of instrument
operation after a cold start.

Reference Phase Detector, Troubleshooting
The
A7Al
Reference Phase Detector compares the output of the 10 MHz Frequency Standard
to the output of the A7A2 100 MHz VCXO and provides the tuning drive voltage for the
VCXO. A phase lock detector in
A7Al
indicates to the main processor (A15) the state of the
Reference Phase Lock Loop.
Samplers
@,
@
The Phase Lock and Lock Indicator Samplers are identical. The diodes are biased to
approximately the same level in each. The dc bias on the diodes is as shown in Table 1.

The Phase Lock Sampler output (junction of R32 and R34) is 0.0 V when locked or with no
10 MHz reference, and approximately
+O.l
V with no 100 MHz input. The Lock Indicator
output (junction of R25 and R23) is -1.5 V when locked, 0.0 V with no 10 MHz reference,
and approximately

@I
The output of the Lock Indicator Sampler is compared to a reference of -0.4 V by
comparator U5. The output of U5 is high for any unlocked condition.
VRl
limits the output
voltage (HULR) to approximately 4.64 V.
This can be checked by disconnecting the 10 MHz input at
A7AlJl
(gray/white cable) and
measuring the output of U5. With the loop unlocked (10 MHz removed), this output should
be approximately 4.64 V.

Q5 functions as a common-base amplifier with feedback to form an oscillator. The
feedback includes the 100 MHz crystal
Yl
and varactor CR1 which are the principal
frequency-determining components. CR1 is tuned by the output of
A7Al
and can vary the
frequency by approximately
fl
kHz. The amplitude of the oscillations is limited by CR3 and
CR4.
TPl
is accessible from the top cover; the voltage should be near -8 V dc for proper
operation. The voltage is adjusted by tuning the oscillator with C4.
100 MHz Buffer Amplifier
@
QS,
Q7,
QS,
Q9,
and
Qll
form a series of 100 MHz amplifiers. They buffer the 100 MHz
outputs from each other as well as from the oscillator.
Quadrupler
@
100 MHz from Q7 in
@J
is applied to T3. The secondary of T3 is connected to Q3 and Q4 to
form a full-wave rectifier. Positive half cycles of 100 MHz to T3 turn on Q3 while negative
half cycles turn on Q4. The collectors are connected together to sum the currents and produce
even harmonics of 100 MHz. The output is tuned to 400 MHz by C3 and
LlO
to select
400
MHz.
400 MHz Amplifier
@
Ql
and Q2 are two common-emitter tuned amplifier stages which amplify 400 MHz and filter
undesired harmonics of 100 MHz. R67, R68, and R69 form a pad which is selected to give
-10
dBm
f2
dB output at 400 MHz.

A7A2 100 MHz VCXO, Troubleshooting
The 100 MHz VCXO supplies all of the fixed reference frequencies for the HP 8566B. Separate
100 MHz outputs are routed to the A6A9, AlOA4, and
A7Al
assemblies. A 400 MHz signal is
applied to the A7A3 assembly. The
A7Al
assembly divides the 100 MHz input to provide 10
MHz and 20 MHz references.
100 MHz Oscillator
@
The tune voltage at
A7A2TPl
is nominally -8 V. If an unlocked condition exists, this voltage
is either -23 V or -1.3 V. If the level is -23 V, check the 10 MHz reference to
A7Al.
If the
level is -1.3 V, check the outputs of the 100 MHz Buffer/Amplifier.
Typical voltage levels for the oscillator transistor Q5 are:
Emitter ..........................................................
-12.8V
Base .............................................................
-11.9V
Collector .......................................................... ..O.O V
100 MHz Buffer/Amplifier
@I
All 100 MHz output levels should be approximately 0
dBm.
Typical voltage levels for each
transistor are as shown in Table 1.

A7A3 M/N Phase Detector, Circuit Description
The M/N phase detector has two programmable frequency dividers: an M divider and an
N divider. M and N are integer numbers which give the ratio of divider input frequency to
divider output frequency. This is the divide number. The input to the N divider is 20 MHz;
the M divider input is the difference frequency between the M/N VCO (355 to 395 MHz) and
400 MHz. The two divider outputs are compared in a phase/frequency detector. The detector
output is amplified and applied to A7A4 M/N Output where it is used to tune the M/N VCO.
In general, the M/N output frequency (from A7A4) is (200 to 10 M/N) MHz. The M/N VCO
frequency is twice the M/N output frequency. The spectrum analyzer frequency diagnostics
(displayed by
(SHIFT)
[MKR~REF LVL)) show the M number, N number, and M/N frequency.
The fifth line of diagnostics contains three integers; the second integer is the M number, and
the third integer is the N number. The next (sixth) diagnostic line gives the M/N output
frequency in MHz (177.5 MHz to 197.5 MHz).
TTL
+
ECL Level Translators
@
The numbers to program the frequency dividers come from Al2 Front-Panel Interface in
binary at TTL levels. U3, U13, and U17 shift these to ECL levels which are approximately
-0.9 V logic high and -1.7 V logic low.
Nl
and Ml designate the least significant bits.
N Divider
@
and M Divider
@
The M and N dividers are virtually identical. Basically, the four most significant bits of N
(three bits for M) N3, N4, N5, N6 load a counter U6. It counts down to two and is reloaded
on the next clock pulse. The two least significant bits,
Nl
and N2, control pulse swallowing
logic which causes the counter to count down to 1 instead of 2 before reloading. The logic
determines the proper number of extra pulses to be swallowed to effect the proper divide
number.
For troubleshooting, it is helpful to set the M and N numbers equal in a 1 MHz span using the
frequency diagnostics explained above. Waveforms at corresponding points in the two dividers
can then be compared to pinpoint the problem.
Mixer
@)
Q3 is an amplifier which drives the LO port of the mixer Q24. It supplies about
+5
dBm
over
the 355 to 395 MHz range. The output of the mixer is the difference between 400 MHz and
the M/N VCO frequency which gives an IF frequency between 5 and 45 MHz. The IF level is
about -17
dBm.
A7A3
1
IF Amplifier
@
The 60 MHz low-pass filter rejects unwanted mixing products from the mixer. Q4 and
U18B
amplify and limit the IF signal and give it the proper levels to run the following ECL
circuitry.
Phase/Frequency Detector
@
The outputs of M and N dividers are compared in
Ul.
When they are in phase, the outputs
of
Ul
are narrow, coincident pulses. For unlock conditions, the output pulses are of varying
widths.
Preamplifier
@
Ql
and
Q2
are a low-noise differential pair preamplifier. Their outputs are combined in the
integrating amplifier of A7A4.
Phase Lock Indicator
@
U2A and
U2B
are voltage comparators which compare each tune line to the average plus a
small offset provided by R29. If the loop unlocks, one of the preamplifier outputs is higher
than the comparison voltage, and the phase lock indicator goes high, indicating the unlock
condition.
A7A3 M/N Phase Detector, Troubleshooting
The A7A3 M/N Phase Detector mixes the A7A4 M/N VCO output (355 to 395 MHz) with
400 MHz from the A7A2 100 MHz VCXO. The product of this mixing and the 20 MHz
reference from the
A7Al
are then divided by the M and N dividers respectively, and their
resultant outputs are compared by a phase/frequency detector. The phase error is used to
tune the A7A4 VCO.
The two dividers (M and N) are identical in operation and their waveforms can be compared
for troubleshooting purposes. The M and N numbers can be set to the same value and various
test points within each divider compared to reveal a malfunction, providing one of the dividers
is known to be operating properly.

The Phase/Frequency Detector outputs pulses whose width is proportional to the phase
difference of the two input signals. These pulses are filtered by the combination of
R24/C5
and
R25/C6.
The Preamplifier amplifies these pulses which are representative of the phase
difference of the two input signals. Typical voltage levels for the Preamplifier are shown in
Table 2.

Phase Lock Indicator
@I
The outputs of the Preamplifier are compared to a reference voltage of -4 V by U2A and
U2B. The output (HULM) is high (active state) when the loop is unlocked.
This can be checked by disconnecting the 400 MHz input at
A7A3Jl
(96 cable) and measuring
the output of U2 (Pl-26). With the loop unlocked (400 MHz removed), this voltage should be
approximately 4.64 V.

A7A4 M/N Output, Circuit Description
A7A4 amplifies the output of the
A7A4Al
M/N VCO in two different paths. One path is
amplification and buffering to drive the mixer in the M/N phase-lock loop. The other path
drives a divide by two which, after further amplification, goes to the
AllA
Sampler.
The integrating loop amplifier which generates the tuning voltage for the M/N VCO is also
included on A7A4.
LO Output Amplifier
@J
Q5 is a common-emitter amplifier followed by a resistive pad to increase reverse isolation.
Q2
is a common-base amplifier which is broadly tuned by L2, LlO, and associated capacitances.
Ql
is another common-emitter amplifier which is followed by a 400 MHz low-pass filter.
Divide By 2
@
U2 is an ECL divide-by-2 Integrated Circuit. U2 generates the M/N output frequency which
is one-half that of the M/N VCO. For frequency spans of greater than 5 MHz, the M/N
control line (LMNE)
g
oes to a TTL high during the sweep. This disables U2, switching off
the M/N output to the
AllA
Sampler. At the beginning of each sweep, U2 is turned back
on and the M/N VCO is phase-locked to give the correct start frequency. During multi-band
sweeps, U2 is turned on at the beginning of each band, but is turned off during the actual
sweep.
Loop Amplifier
@
Ul
is connected as an integrating amplifier and generates -5 V to -35 V for tuning the M/N
VCO. Cl3 is the integrating capacitor; Cl2 and Cl5 compensate
Ul
to guarantee stability.
R33, R34, C14, and R15 compensate the entire phase-lock loop. The 200 kHz low pass filter
rejects the sampling frequency (20 MHz divided by N) and its harmonics which are generated
in the phase detector. CR6, R42, and R41 form an impedance breakpoint that increases the
loop gain by approximately 5 dB when the tune voltage goes below approximately -7 V. This
helps to make the varactor tuning curve linear.
For instruments with A7A4 M/N Output Assembly, part number 85660-60267, power for
integrating amplifier
Ul
is provided by an additional
+20
V connection (Pl-9, P24) and
by
QlO
which generates -15 V from the -40 V supply. The output of
Ul
is buffered by
common-base amplifier
QS
and by emitter-follower buffer
Q9.
A7A4

Voltage-Controlled Oscillator
6~
The M/N voltage-controlled oscillator (VCO) consists of a resonator
A7A4AlAl
and
Q2
with
its associated circuitry. The oscillation frequency is determined by the bias on the varactors
CR1 and CR2 which tunes the cavity resonator. Coarse tuning is provided by Cl, while
C5 is used to vary the output coupling to the cavity thereby varying the output power.
The impedance looking into the emitter of Q2 has a negative real part which provides the
conditions necessary for oscillation to occur.
Buffer Amplifier
@
Ql
is a common-emitter buffer amplifier which provides at least 0
dBm
output over the 355 to
395 MHz range of the VCO.
LO Amplifier
@
QS
and Q7 form a buffer amplifier to assure that there is approximately 0
dBm
to drive the
ECL divide-by-2 IC (U2 in block
0).
R24 and R25 set the proper dc level to drive U2.
M/N Output Amplifier
@
Q3 and Q4 provide buffering between the ECL divider
U2
and the output.
A7A4 M/N Output, Troubleshooting
The VCO tune voltage from the A7A3 M/N Phase Detector is amplified and applied to the
Voltage-Controlled Oscillator (VCO) by the loop amplifier. The VCO output is amplified,
divided by two, and applied to the
AllA
Sampler for phase locking the
AllA
YIG-Tuned
Oscillator (YTO) in 10 MHz increments. A portion of the VCO output provides feedback to
the A7A3 Phase Detector for phase locking of the M/N Loop.

Loop Amplifier
@
The tune voltage from the Loop Amplifier can be measured at
TPl,
located on the cover of
the A7A4. The dc voltage at
TPl,
with the front panel settings indicated above, shoud be
-14.2 V. If an unlocked condition exists, the voltage is approximately -0.5 V or -37.5 V.
If the level is -0.5 V, the probable cause is no VCO output to the A7A3 Phase Detector.
A level of -37.5 V indicates that the 20 MHz reference to the A7A3 Phase Detector is not
present.

A8/A9
A8 Rectifier, Circuit Description
Power is supplied to the instrument through the A9 Power Line Module, which contains
the line voltage selector, to the primary of transformer
Tl.
Three bridge rectifiers and one
center-tapped secondary provide the rectified outputs.
Diodes CR1 through CR4 form a bridge rectifier that provides approximately 55 V for the
-40 V supply, part of the A18 Negative Regulator. CR5 through CR8 form a bridge rectifier
that provides about 20 V for the -10 V supply and the -5.2 V supply, also part of the Al8
Negative Regulator.
Diodes CR9 through CR12 form a bridge rectifier that provides approximately 30 V for the
i-22 V supply, part of the A8 Rectifier, and also the i-20 V and i-12 V supplies, part of the
Al7 Positive Regulator. Diodes CR13 and CR14 form a full-wave rectifier that provides about
12 V for the
i-5.2
V supply, part of the Al7 Positive Regulator.
The
+22
V (STANDBY) supply is an 18 V three-terminal regulator
Ul
which has its common
terminal biased at
+4
V by
Rl,
DSl,
and R2.
DSl
is an LED indicator that indicates the
presence of
+22
V.
VRl
and CR16 form a crowbar circuit for overvoltage protection. Fuse
Fl
provides overcurrent protection. The regulator
Ul
is also internally protected against short
circuits on its output. The
+22
V supply is on whenever the instrument is connected to an ac
line outlet.
The instrument is also protected against line overvoltages by an input crowbar circuit
consisting of VR2 and CR18. This crowbar causes the line fuse to blow if an overvoltage
condition occurs on the line.
Filter capacitors and bleeder resistors for all the switched power supplies are located on the
A23 Motherboard. The filter capacitors for the
+22
V (STANDBY) supply are A8C6 and
A6AlO C8. The location of fuses in the RF Section is shown in Figure 1.

Voltage-Controlled
Oscillator
(VCO),
Circuit
Description
AlOAl
contains the loop amplifier and voltage-controlled oscillator (VCO) for the
PLLl
phase
lock loop. The
PLLl
VCO tunes from 199.9 to 300 MHz (start frequencies of 200.000001
to 300.000000 MHz) for a range of about 4 V to 16 V tuning of the varactor. The
PLLl
VCO drives a counter which divides the frequency by 10. The counter output goes through a
switch and a filter to the
20/30
output. The
PLLl
VCO is turned off in spans greater than
n xl00 kHz but less than or equal to n
x
5 MHz to prevent spurious responses.
Loop
Amplifier
@
The loop amplifier consists of a low-noise differential pair input stage,
Q9
and
&lo,
and
an operational amplifier U6A. Feedback (ac is
)
p
rovided by C34 and R29. The output
of the amplifier goes through a programmable ac voltage divider consisting of R31, R32,
R33, R34, R35 with R36 and C36. The signal is filtered by a 40 kHz low-pass filter which
has two notches tuned to reject the 50 kHz subharmonics created by fractional-n division
(5 MHz
i
100).
U6B
compares the dc varactor tune voltage to about $17.5 V. If the tune voltage goes higher
than this, U6B switches and pulls it down to about
+5
V. Hysteresis in the switching point
of
U6B
provided by R24 keeps U6B from switching back to the original state until the tune
voltage reaches about
+5
V.
Q2
keeps the tune voltage from going below about
+3
V. This is to ensure that the
PLLl
VCO always oscillates and the varactors do not become forward biased in spans where
PLLl
is active.
Gain
Switch
@
U5 latches the four most significant bits of the programming of the
PLLl
fractional-n divider.
These are level translated by U4 which drives four FET switches. By changing the voltage
divider in
@
in this manner, a constant loop bandwidth of 5 kHz is achieved.
200
to
300
MHz
VCO
@
and
Output
Amplifier
@l
The
PLLl
VCO consists of
Qll
which operates in the grounded-base mode. The resonator is
principally CR3, CR4, and L4. Feedback is accomplished with L5, R16, and C17. In spans
greater than n x 100 kHz but less than or equal to n
x
5 MHz, the VCO is turned off by
forward biasing the varactors. Q5 is a common-base buffer amplifier. The output of the VCO
is applied to Q4 where it is amplified and applied to AlOA3
PLLl
IF and the Divide by 10
0.
In spans of n
x
100 kHz, the VCO is tuned as low as 199.000200 MHz.

Output
Switch
@
The output switch is U2 which is a quad ECL NOR gate. For frequency spans greater than
n x 100 kHz, but less than or equal to n
x
5 MHz, the switch input to R3 is TTL low.
U2B
and U2C are on while U2D is off. For all other spans, the opposite states exist. This has the
effect of switching either the output of U3 divider or
Jl
to the
20/30
loop output J2.
Divide
by
IO
@
Q3 is a common-emitter amplifier which drives U3 through a high-pass filter. U3 is an ECL
divide by 10 counter which generates the necessary 19.99 MHz to 30 MHz from the
PLLl
vco output.

Divider,

Description
AlOA2 functions as a programmable frequency divider and a phase/frequency detector. The
divider is programmed by the Al5 Controller to divide the input frequency by the
PLLl
divide number
Nl
down to 5 MHz. This is then compared with a 5 MHz reference in the
phase/frequency detector. The detector output, after amplification and integration, tunes the
frequency of the
PLLl
voltage-controlled oscillator (VCO).
The
PLLl
divide number
Nl
always falls in the range between 3.60 and 13.97. The integer
part is coded in four binary bits while the fractional part (0.00 to 0.99) is coded in two 4-bit
BCD bytes.
Divide

@
U5 constitutes a 3-stage limiting amplifier. U5 is an ECL triple-line receiver which changes
the input to the proper amplitude and dc level (approximately
j-3
V low and
+4
V high) for
driving the subsequent divider. U4A is a D-type flip-flop which divides the limiting amplifier
output by 2.
Input
Latch
@
U9
and UlO are latches which store the divider programming number. The number is clocked
into the latches from the instrument bus with LCK4.
Divide
by
N
@
U12 is a 4-bit binary counter which is programmed with the integer part (3 to 13) of the
PLLl
divide number
Nl.
In operation it is clocked by the output of U4A and counts down to
1. On the next clock pulse, the programming number is loaded into the counter, and the cycle
repeats. Loading time is sensed by U14B when the count is at 2. The next clock pulse causes
U14B to change states which enables the loading of U12 on the subsequent clock pulse.
Fractional
Divide
6J
The fractional divide works on the pulse-swallowing principle. Consider a divider that divides
by N for P-A output pulses and by N
+
1 for A output pulses. Note that the total output
pulses is P. The number of input pulses to get P output pulses is
N(P-A)
+
(N + l)A = NP
+
A.
Therefore, the divide ratio is the number of input pulses divided by the number of output
pulses which is equal to N •l- A/P. In this case P is 100, so N represents the integer portion of
the divide number while A represents the fractional part times 100.
An example best illustrates how the fractional divide works. If the PLL2 divide number
Nl
is 8.57, then
N=8
and
A=57.
The integer divider normally divides by N each divide cycle.
AlOA2

However, the Fractional Divide circuit can set the integer divider to a “hold” state every
N pulses, causing it to “swallow” a pulse and effectively divide by
N+l
for a cycle. In this
example, the Fractional Divide circuit selectively causes the integer divider to “swallow” a
pulse in 57 out of every 100 divide cycles. The integer divider thus divides by 8 for 43 out of
every 100 cycles and by 9 for 57 out of every 100 cycles, averaging out to the desired value of
8.57. Filtering in the phase-lock loop causes the
PLLl
VCO to lock steadily to this average
value.
The fractional divide number is programmed into
Ul
and U2 as two 4-bit BCD bytes.
Ul
and U2 are TTL decade rate multipliers connected in cascade. The input comes from the
integer divide counter U12 via U4B and the ECL to TTL translator consisting of U3B and
Ql.
For every 100 clock pulses into
Ul
and U2, there is output from U3A equal to 100 times
the fractional part of the divide number
Nl.
For example, if
Nl
= 8.57, then 57 pulses occur
at U3A output for every 100 pulses into
Ul/U2.
U3A translates the TTL outputs of
Ul
and
U2 to ECL, which then are latched by U15B, synchronized by U14A, and fed back to U12 to
control pulse “swallowing.”
Phase/Frequency Detector
@
The phase/frequency detector compares the divider output with a 5 MHz reference frequency.
When the two inputs are in phase, the outputs are ECL high, approximately
+4
V, with very
narrow pulses at a 5 MHz rate. When the inputs are the same frequency but different in
phase, one output line is a pulse with a width corresponding to the phase difference; the other
output is high with very narrow pulses. For a difference in input frequencies, the outputs
are pulses of varying widths, but with different average dc voltage levels. The sign of this dc
voltage is set by which frequency is higher and the magnitude is determined by the amount of
frequency difference.
Reference
Divide
by
2
@
U7C is an input buffer amplifier which generates the proper level for ECL (approximately
+3
V low and
+4
V high). U15A divides the 10 MHz input by 2 and applies this 5 MHz to
the phase/frequency detector.
Phase
Lock
Indicator
@
The input to the phase lock indicator is the wired OR Q outputs of the phase/frequency
detector. This input is ECL low (approximately 3 V) when the loop is locked; in this
condition, the dc voltage at the base of Q3 is lower than that at the base of Q2 so Q3 is on
and
Q2
is off. If the loop unlocks, the input to the phase lock indicator consists of varying
width pulses, the average dc value of which is about half way between a logic low and high.
The voltage divider consisting of R35 and R15 causes the voltage at
Q2
base to be lower than
that at Q3 base, so Q2 turns on indicating an unlock condition.
If
PLLl
unlocks, LED
DSl
will turn off, and the CRT message
PLl
UNLOCK will appear.
However, the CRT message PLI UNLOCK will also appear if PLL3 unlocks, as indicated when
AlOA4DSl
turns off. In spans above n x 5 MHz and spans of n x 100 kHz and below, PLL3
functions to shift the output of PLL2 up in frequency by 160 MHz for further division by
PLLl.
(n is the harmonic mixing number.) The two loops PLL3 and
PLLl
always operate
in conjunction; if PLL3 unlocks, then the output of
PLLl
is incorrect whether or not
PLLl
unlocks. The single CRT message
PLl
UNLOCK is used to indicate an unlock in either
PLLl
or
PLL3.

Circuit
Description
AlOA3 functions to mix the output of A10A4 (160.15 to 166 MHz) with the LO output from
AlOAl
(200 to 300 MHz). Theoutput of this assembly is the difference frequency suitably
filtered and amplified to about -10
dBm.
LO
Amplifier
@
The LO amplifier consists of common-emitter amplifiers
Ql
and Q2. CR1 and CR2 provide
limiting to prevent overdriving
Q2
near 200 MHz where
Ql
has more gain.
Mixer
@I
The double-balanced mixer
Ul
operates with about
+7
dBm
LO drive and with -30
dBm
RF signal input. The IF output is about -36
dBm
and covers 30 MHz to 140 MHz. The
185 MHz Low-Pass Filter attenuates the harmonics of the RF signal input. The 10 dB pad
reduces the RF signal input from -20
dBm
to -30
dBm.
IF
Input
Amplifier
@
The IF input amplifier has an input filter to partially filter the RF and LO signals from the
mixer. The amplifier Q3 has emitter degeneration R17 to reduce distortion.
140
MHz
Low-Pass
Filter
@I
The 140 MHz Low-Pass Filter is a modified elliptic filter which must pass 140 MHz while
rejecting 160 to 166 MHz by at least 60 dB. The three adjustable coils optimize the
stopband
by providing nulls at the frequencies shown on the schematic. This filter also rejects the LO
frequencies (200 to 300 MHz).
IF
Output
Amplifier
@
The IF output amplifier consists of two common-emitter stages and an output low-pass filter.
The two stages are coupled by Cl4 and L17 which provide high frequency peaking.

Description
The function of AlOA4 is to mix 160 MHz with the output of AlOA5 (.15 to 6 MHz),
up-converting that output by 160 MHz. The two frequencies are mixed together in a phase
lock loop which has a closed loop bandwidth of approximately 10 kHz.
Frequency
Multiplier
x
1.6
@
The frequency multiplier generates 160 MHz from the 100 MHz at the input. U3 divides the
input by 5 and produces harmonics of the resulting 20 MHz. The 160 MHz
bandpass
filter
selects 160 MHz, which is then amplified by Q5 and buffered with a pad to -20
dBm.
All
three adjustments are set by peaking the 160 MHz signal.
160
to
166
MHz
VCO
@
The 160 to 166 MHz VCO uses
Ql
in a Colpitts configuration.
Lll
centers the frequency
range of the VCO while CR3 is the varactor which tunes the oscillator.
Q2
and Q4 are buffer
amplifiers.
Mixer
@
U7 is a double-balanced mixer which operates with about
f7
dBm
of LO power at 160 to
166 MHz and -20
dBm
of RF signal power at 160 MHz. The desired output is the difference
frequency which falls in the range between 150 kHz and 6 MHz.
IF
Amplifier
@
The output of the mixer U7 is filtered by an 8-section elliptic filter which must reject
14 to 20 MHz, and other higher frequencies. The filter output is amplified by Q3.
Loop
Amplifier
@
The phase detector outputs are connected to the differential inputs of U2.
C9
and R16
provide ac feedback around U2 while dc feedback is provided by the entire phase lock loop.
CR4 and CR5 lessen the charging time of C7 when the input frequency is changed abruptly.
R14, R15, and C7 form an ac voltage divider which sets the loop bandwidth to about 10
kIIz.
The output of the divider goes to the varactor in the oscillator and tunes the VCO.
UlB
prevents this tune voltage from latching at a positive value by sensing when the voltage goes
above 0 V. When this occurs, the output of
UlB
pulls the tune voltage down to the proper
lock range. R13 provides hysteresis to allow time for the loop to lock.

Phase/Frequency Detector
@
U6B and U6C are ECL buffer amplifiers which have the proper output amplitude and dc level
(approximately
+3
V low and
+4
V high) to drive the phase/frequency detector. When the
phase detector inputs have the same phase, the outputs are ECL high with narrow negative
coincident pulses. If there is a phase offset, the pulse widens on one of the outputs depending
on which signal is leading in phase. When the input frequencies are different, the outputs
consist of varying width pulses; the dc or average value of the outputs are different depending
on which frequency is higher and by how much.
Phase
Lock
Indicator
@
The phase lock indicator senses the outputs of the phase detector which are ECL logic high
when the loop is locked. When the loop is not locked, the average phase detector output level
drops to half way between a logic low and logic high.
UlA
switches when this occurs and
causes
DSl
to go out and the phase lock output
HULl
to go to TTL high.
If PLL3 unlocks, LED
DSl
will turn off, and the CRT message
PLl
UNLOCK will appear.
However, the CRT message
PLl
UNLOCK will also appear if
PLLl
unlocks, as indicated when
AlOA2DSl
turns off. In spans above n x 5 MHz and spans of n x 100 kHz and below, PLL3
functions to shift the output of PLL2 up in frequency by 160 MHz for further division by
PLLl.
The two loops PLL3 and
PLLl
always operate in conjunction; if PLL3 unlocks, then
the output of
PLLl
is incorrect whether or not
PLLl
unlocks. The single CRT message
PLl
UNLOCK is used to indicate an unlock in either
PLLl
or PLLS.

Circuit
Description
75
to
150
MHz
VCO
@
The VCO is a varactor tuned oscillator which tunes 75 to 150 MHz. Varactors
CRl,
CR2,
CR3, and CR4 form a series-tuned resonant circuit with L4 and L5. This series circuit
connects the emitters of
Ql
and
Q2.
Q2 is a common-base amplifier whose load impedance is
made up primarily of L9, R14, and R15. The voltage across the load is coupled to the base of
emitter-follower
Ql,
which drives the series resonant circuit.
Bias
Network/50
kHz
Low-Pass
Filter
@
Transistors Q5 and Q6 and associated components form a filtered -32 V source to bias the
varactor tuning diodes. In the absence of tuning current, the varactor bias is set by R2 to
approximately -17 V. Tuning current from the AlOA8 PLL2 Discriminator passes through
the 50 kHz low-pass filter and acts to pull this bias voltage in a positive direction. Tuning
sensitivity is set by R4, to -10
Mhz/mA.
75
to
150
MHz
Output
Buffer
@
Q4 is a grounded-base amplifier to isolate the VCO from the load circuits. The output of Q4
is filtered, attenuated, and used to drive the AlOA7 PLL2 Divider.
Frequency
Dividers
@
Q3 isolates the VCO from the dividers and develops the required drive voltage. Note that all
of the dividers and gates are ECL with
Vcc
hooked to
+5
V and
VEE
grounded. U3 divides
the VCO frequency by 5; to the range of 15 to 30 MHz. U6C provides isolation. U2 divides
the output by 5; to the range of 3 to 6 MHz. U2 then further divides by 2 and
Ul
divides
the output by 10, to the range of is 0.15 to 0.30 MHz. The output of
Ul
is fed to the
AlOh
PLL2 Discriminator.
Small
Span
Switch
@
U5 functions as a single-pole double-throw switch, controlled by SW2. For frequency spans
greater than n x 5 kHz up to n x 100 kHz, SW2 is TTL high, routing the 3 to 6 MHz signal
from U2 through U5C, U5B, and U5D to the AlOA4 PLL3 Up Converter (n is the harmonic
mixing number). When the frequency span is n x 5 kHz or less, or greater than n x 5 MHz,
SW2 is low, routing the 0.15 to 0.30 MHz signal from
Ul
through U5A and U5D to the PLL3
Up Converter. R33 and R34 shift the TTL levels to ECL levels.
AlOA5

0.1
to
5
MHz
Span
Switch
@
For frequency spans of greater than n x 100 kHz up to n x 5 MHz, SW1 is TTL low, routing
the 15 to 30 MHz signal from U3 through U6D, U7D, and
Tl
to the
AlOAl
PLLl
VCO.
When SW1 is high, the circuit provides 90 dB of isolation. R35 and R36 shift the TTL levels
to ECL levels.

(PLL2)
Phase
Detector,
Circuit
Description
The purpose of the AlOA6 PLL2 Phase Detector is to compare the output of the AlOA5
PLL2 VCO (after division by the AlOA7 PLL2 Divider) to the 500 kHz Reference from the
A7Al
Reference Phase Detector. The phase difference is converted to an error voltage used to
correct the PLL2 VCO frequency.
Phase-Frequency Detector
@
The phase-frequency detector responds to the phase difference between the 500 kHz reference
input and the divided input from the AlOA7 PLL2 Divider. Assuming both flip-flops U6A
and
U6B
have been cleared,
Q9
is on and
QlO
is off.
Q9
supplies about 3
mA
current which
is sunk by current source
QS
resulting in approximately zero current flow through the 50
kHz low-pass filter to U3. On AlOA6 PLL2 Phase Detector, HP part number 85660-60276,
transistor
Qll
is added as an active
pulldown
to reduce glitches that could cause momentary
false unlocks.
A pulse from the PLL2 Divider on Pl-19 clocks the Q output of U6A high, turning
Q9
off. A
subsequent reference pulse on Pl-20 clocks the Q output of
U6B
high, which will immediately
reset both flip- flops through U7A. Thus the effect of a pulse at Pl-19 leading one at Pl-20 is
to momentarily reduce the output current. Therefore, if the divided output leads the reference
in phase, the current decreases. Similarly, if the reference phase leads, the current increases
because
QlO
is connected to the Q output of U6B.
If the two inputs have different frequencies, the pulse relationships become complicated, but
the net effect is positive output current if the reference frequency is high.
U3 serves as an amplifier to provide the high currents necessary to rapidly charge the
integrating capacitor C7 in the following stage. VR2 and VR3 serve as clamps, limiting the
output swing to f5.8 V.
Unlock
Indicator
0%~
When the phase lock loop is in a steady state condition, the voltage at
TPl
is zero. If
unlocked, the voltage will be non-zero except for transients passing through zero. When
the voltage
TPl
exceeds
f0.7
V, either
Ql
or
Q2
is turned on, discharging Cl5 or Cl4
respectively and tripping comparator
Ul.
When
TPl
voltage settles to less than f0.7 V, Cl4
and Cl5 must recharge before the comparator is reset. This takes 5 ms. The comparator
output is TTL high for an unlock condition and remains there for 5 ms after a lock condition
is established.
AlOA6

Analog
Integrator-Sample
and
Hold
@
U2 and C7 form an integrator which integrates current flowing from U3 through R8. The
output of the integrator is summed with other signals in U4 and ultimately controls the VCO
frequency. In steady state conditions, TP3 will settle to a constant voltage which tunes the
VCO to the correct frequency. If the voltage at TP3 is constant, the input current must be
zero, so opening FET switch Q3 will not change the voltage at TP3. When PLL2 is being
used in its swept mode, the loop is locked to a start frequency set by AlOA7 PLL2 Divider,
then Q3 is opened. This breaks the lock loop, permitting a sweep to be executed.
Q3 is closed with zero gate voltage, and open with -7 V gate voltage. The gate drive comes
from Q6 and Q7, which translate the TTL level lock-sweep signal on Pl-2 to the
O/-7
V
levels. Pl-2 is also connected to U6A and
QS,
which results in zero voltage at
TPl
during a
sweep. A negative voltage may turn on Q3, changing the charge stored on C7.
Digital
Integrator
@
The analog integrator does not have sufficient control range to correct initial warm-up drift
and long term aging. If TP3 goes below -4.7 V, Q5 is turned on and its collector voltage is
pulled down to -1.4 V. At this point, CR4 and CR3 become forward biased, clamping U2
and
preventing further negative movement of TP3.
Simultaneously, the input of
U7B
will have been pulled low, which turns on a 2 kHz oscillator
made up of U7C, R20, and
Cll.
This clocks the count up input of counters U8 and U9,
which drives DAC UlO. UlO sources negative current to the summing junction of U4 and this
current increases in magnitude as U8 and
U9
count up. When the current reaches a value
which tunes the VCO to the proper frequency, TP3 moves positive, shutting off the oscillator
and returning control to the analog integrator. An analogous sequence occurs when TP3 tries
to rise above
+5.7
V.
Output
Amplifier
@
U4 serves to sum signals from the analog integrator, DAC, and
Rll.
Rll
is a high frequency
signal path shunting the integrators.

Description
Reference
Divider
@
A 10 MHz signal derived from the quartz crystal reference is amplified by
Q2
and used to
drive divider U4. The divide by 10 output of U4 drives U16, whose divide by 2 output goes
to the AlOA6 PLL2 Phase Detector. This 500 kHz signal is used as a reference to which
the programmable divide output of the PLL2 Divider is compared. The TTL input on Pl-2
disables the reference divider during sweeps.
Prescaler
GJ
The -18
dBm,
75 to 150 MHz input from AlOA5 PLL2 VCO, is amplified by
Ql
and used to
drive prescaler
UlA
which is a variable-module divider. It divides by 10 if pin 9, “PSW” is
high; it divides by 11 if pin 9 is low.
UlB
is an ECL circuit which contains an ECL to TTL
translator. Pin 7 is the TTL output, which drives gate U9C. U9C is used as a buffer to drive
the multiple of loads on its output; the “CLK” line.
The prescaler should be thought of as a
~10
with the ability to “swallow” input pulses. If
the PSW line is low, in effect one input pulse is lost (swallowed) for each output
(CL10
pulse
produced.
Latches
@
U12, U13, and U14 are latches which store the divider programming number. The number is
clocked into the latches with
LCKl
and LCK2. U14 also latches in SW1 and SW2, which are
sent to AlOA5 PLL2 VCO and
AlOAl
PLLl
VCO.
Direct
Divide
@
U8 and U15 are cascaded dividers whose state outputs are sensed by U9B. The CLK line
from the prescaler clocks U8. When the count reaches 25, the output of
U9B
goes high. This
initiates a divide sequence by J-K flip-flops UlOA and UlOB, which are clocked by CLK. The
Q output of UlOA goes high on a count of 27 and low on 29. This signal is output to the
AlOA6 PLL2 Phase Detector. The Q output of UlOA goes low on a count of 27, resetting U8
and U15. When it returns high on 29, the sequence resumes.
U15 is preset to a count of zero and U8 to a count of 0 to 9 depending on input data. Thus, if
U8 is preset to 0, the circuit divides by 29. If preset to 9, the circuit divides by 20.
Since the prescaler has already divided by 10, the 75 to 150 MHz input is divided by numbers
200, 210, . . . 290 according to the BCD digit programming U8. Since the output is locked
to 500 kHz by the phase lock loop, the VCO is programmed from 100 to 145 MHz in 5 MHz
steps.

Synchronizer
0
Other divide numbers are provided through the pulse swallowing technique. The output
frequency is held by the lock loop to 500 kHz. If N input pulses per second are swallowed,
the input frequency must rise by N Hz to keep the output constant. If N input pulses are
swallowed for each output pulse, input frequency must rise by N x 500 kHz.
The pulse swallow synchronizer accepts pulses from the fractional counter and integer counter,
and at the proper time, as determined by the CLK line, drops the PSW line to swallow input
pulses.
Integer
Counter
@
U7 is a presettable counter which is preset to an externally programmable count by the RST
line. RST pulses come from the direct divide output, and occur at a 500 kHz rate. After
each RST pulse, U7 counts CLK pulses until a count of 9 is reached. A count of 9 causes the
output of U9A to go high. The pulse swallow synchronizer drops the PSW line on CLK pulse
after the RST pulse, and raises it two CLK pulses after U9A goes high. PSW therefore is low
one CLK pulse longer than the count time. If U7 is preset to N, (9-N) + 1 input pulses will
be swallowed for each CLK pulse, forcing the input frequency to rise by (10-N) x 500 kHz.
Fractional
Counter
@
U5 and U6 are rate multipliers. They provide the function
FOUT
=
FIN
x
N/100
where N is a
two digit BCD number (8 bits). The least significant digit goes to U5, the other to U6. The
output comes from U5 and triggers a 1.6 ps pulse from one-shot multivibrator
Ull.
The input frequency to the rate multipliers is 500 kHz, so
FOUT
= N x 5 kHz.
The output from
Ull
goes to U2A. A high input at U2A causes the synchronizer to swallow
one less pulse per RST pulse than it would have other wise. The fractional counter therefore
causes the input frequency to drop by N x 5 kHz, where N ranges from 0 to 99.

Description
The AlOA8 PLL2 Discriminator combines the error voltage information from the AlOA6
PLL2 Phase Detector, the attenuated scan information (SCAN DAC IN) from the Al6 Scan
Generator, and the tuning information from the Al2 Front-Panel Interface (via the Instrument
Bus) to produce a tuning current to tune the oscillator in the AlOA5 PLL2 VCO.
Pulse
Generator
@
AlOA5 PLL2 VCO provides an ECL level
.15
to
.30
MHz input which is amplified by Q6
and Q7. At the beginning of a cycle, both inputs of gate U7D are low. When Q7 collector
goes high, U7D output goes low, saturating
Qll
and causing resonator L4, C15, Cl6 to ring
at 5.2 MHz. This damped oscillation appears at
Q9
collector, is clipped by
&lo,
and used to
drive counter U6. U6 is preset to a count of 6. When the count reaches 8, the (8) output of
U6 goes high. This is fed back to the other input of U7D, holding its output low after the
input from Q7 goes low. After 1.6
ps,
the count reaches 16, (8) goes low again,
U7D
output
goes high,
Qll
is turned off, resulting in the resonance being damped by R17. At the count of
16, U7C and U7B reset the counter to 5. Before the oscillation is fully damped, the counter
gets clocked to 6. U7A prevents a latch-up condition by clearing the counter in the event that
the output of U7D remains low for a long period of time.

Current
Source
@
The -7 V source, via R6 and Q3A, provides current which develops a stable 7 V drop across
R7 and Q3B. This acts as the reference for a 3.2 mA current source comprised of U4 and Q4.
This current flows to ground through Q5A when the (8) output of U6 is low. If an input pulse
has triggered the pulse generator, the current is switched through
Q5B
for 1.6
ps.
Q5B’s
collector current goes through a low-pass filter to the summing point of the discriminator loop.
The average value of this current is directly proportional to the input frequency, being 1.5 mA
at 300 kHz. The current to frequency ratio is adjustable
*l%
by the phase lock input on
PI-28.

Summing
Amplifier
@
U3 is a noninverting integrator which responds to the voltage at the loop summing point,
the junction of C22 and R43. The output of U3 is connected through R45 to the output
summing network, whose output tunes the AlOA5 PLL2 VCO. Non-zero voltages at the loop
summing point will therefore cause the VCO frequency to change, until the current from the
discriminator reaches a level which cancels the other input, returning the summing point
voltage to zero. In this way, the VCO frequency is forced to be exactly proportional to the net
current fed to the summing point.
Pretune
@J
The pretune circuit tunes the discriminator loop approximately to the desired frequency. The
phase lock loop then applies small corrections to get the frequency exact. A
lo-bit
binary
word representing the pretune frequency is latched by
U9
and U12. The data programs
DAC
Ull,
whose output goes to UlO. If the input is all zeros, the output of UlO is zero.
The pretune current is then that which flows through R40: -1.5
mA.
This tunes the input
frequency to 300 kHz. A binary word representing decimal 1000 will result in
+6.84
V at
UlO’s
output, adding
+0.5
mA
to the summing point. The resulting -1.0
mA
tunes the loop
to 200 kHz.
Scan
Attenuator
@
The attenuated scan ramp is fed to the loop summing point via the range resistors selected
by analog switches
UlA
and
UlD.
If
UlD
is closed, a
+lO
V ramp causes a 0.5 MHz span
(referred to the 15 to 30 MHz VCO output).
UlA
closed results in a 5 MHz span.
UlB
is
closed when
UlA
is, feeding a current to the summing point which compensates for drift and
nonlinearity in
UlA.
U2A and U2B direct the scan ramp directly to the VCO. This “forward feed” helps
compensate for the rather slow response of the discriminator loop.
U2C and U2D perform a logic function:
U2-10
HI,
U2-15
LO for wide scans;
U2-10
LO,
U2-15
HI for narrow scans, and both HI for scan disabled.

@
Ql
and Q2 form a low-noise current summing point for error signals from U3 and forward feed
from the scan and phase lock inputs. The output current goes to the AlOA5 PLL2 VCO.

YIG-Tuned
Oscillator
(YTO)
Phase
Detector,
Circuit
Description
The
AllA
YTO Phase Detector compares the frequency and phase of the
AllA
Sampler
IF signal to the output of the A10
20/30
Synthesizer Loop. The resultant error signal is
integrated, amplified, and applied to the A21 FM Coil Driver where it is routed to either the
main coil (dc path) or FM coil (ac path) of the
AllA
YTO. This tunes the YTO frequency
the proper amount in the proper direction to maintain phase lock.
70
MHz
LPF
@
The output of the
AllA
Sampler (IF IN) is passed through a 70 MHz LPF to remove any
unwanted frequencies which may have been introduced during the sampling process.
Limiters
@
and
@
and
Divide
by
Twos
@
and
@
Each of the two input signals (IF IN and
20/30
IN) are passed through a limiter to
establish ECL signal levels. Each signal is then divided by two before being applied to the
phase/frequency detector. This lowers the frequency at which the detector must operate.
Phase/Frequency Detector
0
and
1.5
MHz
LPF
@
The two input signals (IF IN and
20/30
IN), after being divided by two, are applied to Phase
Frequency Detector U3. The function of U3 is to output a pulse which is related to the phase
difference of the two input signals. The width of this pulse is directly proportional to the
amount of phase difference. If the IF signal leads the
20/30
signal, a negative pulse appears at
U3 pin 3
(TP3),
the width of which is proportional to the amount of phase difference. If the
20/30
signal leads the IF signal, a negative pulse appears at U3 pin 12 (TP2). In each case,
the other output is an ECL high (approximately -0.6 V). If the inputs are in phase, one of
the detector outputs is an ECL high (approximately -0.6 V) with narrow negative spikes and
the other just an ECL high. The detector outputs are averaged in the 1.5 MHz LPF before
being applied to the differential amplifier.
Differential
Amplifier
GiJ
The detector outputs are applied to Differential Amplifier Q4. The output of this differential
amplifier is directly related to the phase difference of the IF IN and
20/30
IN signals.

Loop

Switch

is enabled. The enable
signal HYGH (High = YTO Gain High) is from the Al2 Front-Panel Interface and is high
whenever a frequency span of less than 25 kHz is selected. This high turns on
Q2
which
turns on Q3 which causes
Ql
to saturate.
Ql
then effectively becomes a short, placing R14
between the emitters of Q4A and Q4B. This lowers the emitter resistance by a factor of four,
increasing the gain by approximately 12 dB. This improves phase noise at narrow frequency
spans
(<25
kHz).
Integrator
#l
@
Integrator
#l
produces a ramp output proportional to the amplitude and period of the input.
This integrating action is performed by R16, R21, and
Cl2.
Diodes CR2 and CR3 limit the
upper and lower ramp voltages to one diode drop (approximately 0.6 V). This ramp may be in
either a positive or negative direction depending on the input. When the loop is locked and
the instrument is in zero frequency span, the output is a dc level.
Integrator
#2
@
Integrator
#2
also produces a ramp output but of greater amplitude due to zener diodes
VRl
and CR2. The upper and lower ramp voltages are limited by VRl/C!RG and
VR2/CR7
to
approximately 6.8 V. This corresponds to a capture range of about
&20
MHz, since YTO
sensitivity is -3 MHz/V. Integrating action is performed by R24, R25, and C16. In zero
frequency span, when the loop is locked, the output is a dc level.
Sample
and
Hold
@I
The purpose of the sample and hold
(Ul
and associated circuitry) is to sample the ramp
voltage output of the integrators to tune the YTO frequency, then hold this dc value to
prevent the YTO loop from affecting the YTO Sweep.
For frequency spans less than 5 MHz (including ZERO),
Ul
is held in the sample mode. This
means that the YTO is phase locked during the entire sweep for frequency spans less than 5
MHz.
For frequency spans greater than 5 MHz (fundamental mixing only), phase lock is performed
only at the start of each sweep as follows. Just prior to a sweep,
Ul
is placed in the sample
mode, the sampled output is applied to YTO to correct its frequency, and phase lock occurs.
Then
Ul
is placed in the hold mode, which stores the sampled output voltage across Cl. This
voltage keeps the YTO tuned to the correct frequency. The sweep occurs, and the sequence is
repeated.
The mode of operation of
Ul
is determined by control signal HLEY (High = YTO Lock
enable) from the Al2 Front-Panel Interface. The duration of the sample mode is determined
by HLEY which varies with frequency span selected.

Unlock
Detector
@
Phase lock is obtained by use of the YTO (FM coil for ac corrections and main coil dc
corrections) which has a frequency tuning range of approximately
f20
MHz at 3 MHz/V
sensitivity.
Unlock detector U2 and associated circuitry is used to determine when the error voltage is
too large for the YTO Loop to respond. This detection is performed for both positive and
negative error voltages by U2A and U2B respectively.
If the error voltage (ramp output of Integrator
#2)
exceeds f6.1 V, control signal HULY
(High = YTO Unlocked) is generated and routed to the Al2 Front-Panel Interface where it
causes a service request to be generated. Coded information corresponding to this request is
placed on the Instrument Bus and is detected by the Al5 Controller which turns on the YTO
UNLOCK annotation on the CRT.

Description
The
AllA
Sampler mixes the output of the
AllA
YTO (RF INPUT) with the Nth
harmonic of the output of the A7 M/N Reference Loop (M/N IN). The 20 to 30 MHz
difference signal (IF OUT) is output to the
AllA
YTO Phase Detector to be compared
with the 20 to 30 MHz
(20/30
IN) from the A10
20/30
Synthesizer for the purpose of phase
locking.
Sampler
Drive
Amplifier
@
The output of the A7 M/N Reference Loop (M/N IN) is applied to common-base amplifier
Q3. The output of Q3 is ac coupled to common-emitter amplifier QS. The output of
QS
is
passed through an impedance matching network which provides maximum drive power to
AllUl Sampler. Adjustments Cl and C2 optimize this impedance match.
Sampler
Al
1Ul
AllUl Sampler contains a step recovery diode (SRD) circuit to create harmonics of the M/N
IN signal which are mixed with the low-level (-15
dBm)
RF INPUT signal from the
AllA
YTO (via the
AllAl
Coupler/Isolator/Amplifier and
AllA
Attenuator/6.2
GHz LPF).
When the YTO Loop is phase locked, the mixing product of the Nth harmonic of the M/N IN
signal and the RF INPUT signal is precisely equal to the
20/30
IN signal from the A10
20/30
Synthesizer.
IF
Preamplifier
@
The IF Preamplifier consists of common-source amplifier Q4, common-emitter amplifier
Q2,
and feedback divider
R20/R16.

and
70
MHz
LPF
@
The AllUl Sampler output, after being amplified, is buffered by emitter-follower Q7 and
applied to a 70 MHz low-pass filter. This filtering is done to remove any unwanted mixing
products produced by the mixing action of the sampler.

Gain
Adjust
@
After being filtered, the IF signal is applied to common-emitter amplifier Q6 which has
adjustable gain. IF Gain adjustment
Rl
can be adjusted to provide from 5 dB to 20 dB of
gain. This is used to adjust the level of the IF signal to the proper level for comparison to the
20/30
signal in the
AllA
YTO Phase Detector.
Output
Amplifier
@
The IF signal is further amplified by output amplifier Q5 and
Ql.
Gain is approximately
21 dB. This provides the proper level signal to drive the
AllA
YTO Phase Detector.

Al2
Front-Panel
Interface,
Circuit
Description
Al2 Front-Panel Interface contains the miscellaneous digital functions for interfacing with the
Al5 Controller.
Keyboard Matrix
@
The
keyboard is organized as a matrix (rows and columns) of normally open SPST switches.
The rows are driven by U2 and U3. U6 functions as a key-down detector. Q2 and associated
circuitry
debounce
the key switches, and
U14B
latches the key-down condition.
Ul
and U4
gate the key columns onto the Data Bus. By selectively enabling the key rows, Al5 Controller
can poll the keyboard.
Oven
Cold
Sensor
@
When U22 senses the oven line is less than
+17
V, it tells the Controller that the oven is no
longer cold.
Rotary
Pulse
Generator
(RPG)
Control
@
UllB
enables the RPG, allowing the pulses to be counted.
UllA
detects the direction of
rotation of the RPG (rotation of the DATA knob on the front panel).
U18
and
U19
count the
number of RPG pulses since the last RPG RESET. U28 provides a
holdoff
of about 200 ms,
until service is requested, giving the instrument time to respond to the last request and to
continue to sweep before the next request occurs; that is, to give the operator visual feedback.
Service
Request
@
This circuit encodes the various requests for service for the Al5 Controller.
U24 encodes the service request. U27 is a change detector (HXRF or LRMT), and U25
latches these changes. U14A detects and latches the falling edge of HSWP.
U13 also provides the reset pulses for clearing the request latches U14A, U14B, U16A, U25A,
and U25B.
U16B
is cleared by any pending request (that is, it restarts Al5 Controller) by
U24.
Q3 pulls HSWP low whenever a request is pending.
U12 gates the encoded request and also places HXRF or LHBZ on the Data Bus.
Al2
1
M/N
Storage
@
Each flag can be enabled (interrogated), or all flags can be enabled.
U30
and U32 provide the
logic, and
U20
stores the state of the enabled flags.
Address Decoder
@
U7, UlO, and U33 decode the address lines, enabling the appropriate ICs to gate or store data
for the Data Bus.
Attenuator
Correction
Rom
@
U8 is a PROM (programmable read-only memory) that contains the attenuation errors
(calibration data) of the RF attenuator.
Control
Lines
@
U9
controls certain mainframe functions, such as turning off the internal reference oscillator
(IISTD).
Options
@
U21
gates the Options jumpers onto the Data Bus.

Al5
Controller,
Circuit
Description
The Al5 controller performs the main control functions of the spectrum analyzer. The
board includes a 16-bit microprocessor (the instrument’s main processor), read-only memory
(ROMs), random-access memory (RAMS), and HP-IB circuitry.
The schematic shows how the main processor, memory, HP-IB, and other circuits on the A15
Controller are interconnected via the microprocessor’s 23-bit address bus and the 16-bit data
bus. To control signal flow on these buses, various signals must be derived from the address
bus signals and the microprocessor’s remaining output signals. These control signals are
generated by two programmable-array-logic integrated circuits (PALS) and other discrete
logic (R/W DECODE, ADDRESS DECODER AND DTACK, ADDRESS DECODE, and
LTIO/LBIO blocks). The signals are used by the microprocessor to control data flow and
address decoding on the Al5 Controller and to control signal flow over the Instrument Bus.
The 16-bit, 8 MHz MC68000 microprocessor receives input through the front panel keyboard
or from HP-IB, performs the necessary decoding and calculations, and outputs the proper
control signals to execute a specific spectrum analyzer operation. Typical main processor
tasks include phase-locking the YTO, selecting the correct sweep time and frequency span,
setting the IF-Display Section resolution bandwidth and sensitivity, and displaying the current
control settings on the CRT through the A3 Digital Storage Section. Instructions that tell the
microprocessor how to accomplish these tasks, the firmware, are stored in ROMs located on
the Al5 Controller. In addition, custom commands and programming can be downloaded into
RAM, permitting specialized operation without requiring a dedicated controller.
The microprocessor performs a brief power-on pretest (POP) at instrument turn-on, verifying
operation of critical circuits and lighting front-panel check LEDs I and II. In addition, LEDs
located on the top edge of the Al5 Controller provide information to help identify particular
faulty circuit components in case a failure occurs.
The instrument’s main memory consists of read-only memory (ROM) and random-access
memory (RAM)
h’
h
w
rc
are located on the Al5 controller. Each 16-bit word in memory is
composed of two 8-bit bytes. The ROM, used to provide permanent storage of the firmware,
is composed of four 32 Kbyte erasable programmable read-only memory (EPROMS). This
provides a total of 64 K-words of ROM. The RAM, used for erasable storage of custom
instructions and programs, is composed of four 8 Kbyte static CMOS memory-integrated
circuits for a total of 16 K-words of RAM. A lithium battery located on the Al5 Controller
provides battery backup power to the CMOS RAM to preserve the contents of memory
when power is removed from the instrument. The typical in-circuit life expectancy of the
non-rechargeable battery is at least three years.
The HP-IB allows the spectrum analyzer to communicate with external devices. It is
implemented using four ICs: a data latch, an HP-IB processor, and two bus transceivers.
The Al5 Controller clock circuit generates an
~-MHZ
clock signal for the 16-bit microprocessor
and a synchronous
~-MHZ
clock signal for the HP-IB processor. The appropriate clock
A15 1
frequency is derived from division of the output signal of a 14.7456 MHz hybrid crystal clock
oscillator.
The Al5 Controller firmware includes extensive diagnostics which are executed whenever the
instrument is powered up or the INSTRUMENT PRESET key is pressed.
The microprocessor executes a self-test routine and indicates the results via LEDs. A memory
failure, microprocessor failure, or Instrument Bus failure can usually be pinpointed to the
failed component using these indicators.
HP-IB
Address
Switch
The position of the address switch on the Al5 Controller
(A15SWl)
determines which HP-IB
address is used by the analyzer when the line power is turned on.
The address switch is preset to 31 (switches Al through A5 pressed up) at the factory. If the
CMOS backup battery has not been discharged, the last HP-IB address used by the analyzer
is active at instrument power-up. If the backup battery is discharged, the analyzer will default
to an HP-IB address of 18 at instrument power-up.
If the address switch is set to any address from 0 to 30, this address will be used as the
read/write address by the analyzer with power on.
Switch A6 is also set in the “up” position (logic 1) at the factory. A6 in this position does a
checksum verification of the two pairs of ROMs on the Al5 Controller as part of the self-test
routine with power.
HP-IB
Signal
Ground
(A25)
The A25 HP-IB Signal Ground assembly provides chassis ground for the HP-IB shield. Pins
12 and 18 through 24 of the HP-IB connector J2 are immediately grounded to the chassis
upon entering the instrument.
Firmware
The firmware for the HP 8566B has been changed several times since its origin. These changes
of firmware have required that U37, U38, U39, and
U40
EPROMs be changed. The following
table lists each of the HP 8566B firmware changes, the firmware date (displayed when the HP
8566B is powered on), the HP part numbers for the EPROMs, and the serial number prefixes
of the HP 8566B that the firmware revision was originally manufactured with.

Controller,
Troubleshooting
Troubleshooting the Al5 Controller is divided into two levels:
Level 1 is Self Test which uses the built-in diagnostics of the spectrum analyzer to isolate
the failure. No external test equipment is required.
Level 2 is Manual Tests which require the use of general troubleshooting equipment such as
a digital voltmeter and oscilloscope. This level is required when the Self Test can’t isolate
the failure.
Level
1
Self
Test
The Self Test is run on power-up and after pushing the [INSTRUMENT PRESET) key. Two
front panel
LEDs,
INSTR CHECK I and II, give an indication of Self Test results (without
removing any covers from the instrument). There are also 15 LEDs on the Al5 Controller
(DSl
through DS15) that will help isolate a problem.
Front
Panel
INSTR
CHECK
I
and
II
LEDs
The two red INSTR CHECK LEDs are forced on whenever the instrument is turned on or
the (INSTRUMENT PRESET) key is pushed. The main processor then performs a check of itself, a
checksum verification of all ROMs on the Al5 Controller, a partial check of the Instrument
Bus (50-wire bus), and a read/write check of the
RAMS
and A3A4 Memory in the IF-Display
Section.
If all the checks pass, both INSTR CHECK LEDs are turned off. If the check fails, one or
both INSTR CHECK
LEDs
remain on.
a. Both INSTR CHECK LEDs on indicates a problem on the Al5 Controller. First remove
the Al5 Controller and make sure that the 50-wire ribbon cable and HP-IB ribbon cable
are pressed all the way onto
A15Jl
and A15J2 connectors. Reinstall the Al5 Controller. If
both front panel INSTR CHECK LEDs still remain on when the instrument is turned on,
follow procedure under Al5 Controller Self Test.
b. Left LED (INSTR CHECK I) on indicates a failure occurred when checking Digital Storage
Memory (A3A4). First check to ensure that a LINE power cord is connected to the
IF-Display Section. Also check to se that the rear-panel Analyzer Bus Interconnect Cable,
W31, is properly connected. If INSTR CHECK I still remains on when the instrument is
turned on, troubleshoot the A3 Digital Storage in the IF-Display Section.
c. Right LED (INSTR CHECK II) on indicates a failure occurred during the partial check of
the Instrument Bus.
Note The partial interface check reads the key column lines
(KC0
through
KC7) from the Al and A5 front panels. If any front panel key is shorted
or stuck closed, INSTR CHECK II LED should remain on after the Self
Test is completed. This part of the Self Test can easily be verified by
pushing any key, except
ILCL),
and holding the key in while pushing the
[INSTRUMENT PRESET) key. If the I/O interface check routine is working, INSTR
CHECK II LED will stay on.
d. Suspected Digital Failure but no INSTR CHECK LEDs on may indicate a RAM or I/O
bus failure which is not checked in the normal Self Test or “POP” (Power On Preset). If
4 Al5
the two front panel INSTR CHECK LEDs turn on when the LINE switch is set to ON
and within a few seconds turn off (indicating no digital problems), but symptoms (such as
improper CRT display or improper response to particular commands) indicate that the
problem is in the digital area, a “LONG POP” can be performed. LONG POP is very
similar to the normal POP except an additional processor check is performed, all of the
RAM locations in Digital Storage (A3A4 Memory) are checked, and the memory (RAM) on
the Al5 Controller is verified.
Since these more extensive checks require altering information that has been stored in
RAM, LONG POP requires an internal jumper on the Al5 Controller. To perform a LONG
POP:
n Set the LINE Switch to STANDBY.
n Place a jumper between ST or STS to T3
q On Al5 Controller (HP part number 85660-60209) jumper
A15TP4
(STS) to
A15TPl-7
(TV
c7
On Al5 Controller (HP part number 85660-60245) jumper
A15TPl-9
(ST) to
A15TPl-8
(T3).
q (Refer to Al5 Controller Component Location Diagrams for location of test points).
n Set the LINE switch to ON.
When LINE switch is then set to ON, the two red INSTR CHECK LEDs are forced on and
the main processor steps through the Self Test routine, expanding the normal POP by the
additional tests mentioned. The expected results for a LONG POP are exactly the same as
for the normal POP of INSTR PRESET as described above under “Front Panel INSTR
CHECK I and II
LED?.
Because LONG POP is a “destructive test” (it alters any information that has been stored
in RAM), it should be performed only as a last resort effort in troubleshooting what
appears to be a memory or processor-related problem.
Al5
Controller
Self
Test
The Al5 Controller Self Test is run on power-up and after pushing the (INSTRUMENT PRESET]
key. Fourteen
LEDs
(A15DSl
through A15DS14) on the Al5 Controller give an indication of
the Self Test results. All 14 LEDs are forced on whenever the instrument is turned on or the
(INSTRUMENT PRESET) key is pushed. The main processor (A15U26) then performs a check of
itself, a check of the Peripheral Interface and Timer chip, a checksum verification of all the
ROMs on the Al5 Controller, a read/write check of the
RAMS
on the Al5 Controller, and an
Instrument Bus check that checks the I/O Bus, Address Bus, and Data Bus for stuck lines.
If
all
the checks pass, the 14 LEDs are turned off serially as each check is completed. If the
checks fail, one or more LEDs remain on. Refer to Table 1, “A15 Controller Self Test Fail
Indicators,” at the end of this troubleshooting section.
Other failure modes to look for are:
a. If the 14
LEDs
turn on but are all turned off at the same time (instead of sequentially), the
Peripheral Interface and Timer chip has most likely failed.
b. When an I/O failure is indicated (DS3, DS4, or a combination of these LEDs remain on), it
may become necessary to use an oscilloscope to locate a stuck line.
A15
5
Try replacing
U20
and U42
PALS
first, then try replacing U39 and
U40
ROMs. If I/O
failure still occurs, probe I/O lines with oscilloscope.
Level
2
Manual
Tests
If the Self Test doesn’t lead to a failed component, it will be necessary to use a DVM or an
oscilloscope. The following procedure may help locate the failed component:
a. Check all power supply voltages that supply power to the Al5 Controller.
b. Check processor clock by connecting oscilloscope to
A15TP2-4
(CK). The clock frequency
should be approximately 7.36 MHz. The amplitude should be approximately
+5
V (HIGH)
and 0 V (LOW). Al
so
check for LCLK at pin 7 of A15U27B.
c. Check HP-IB clock at pin 5 of A15U27A. The HP-IB clock frequency should be
approximately 3.68 MHz. The amplitude should be approximately
+5
V (HIGH) and 0 V
(LOW).
d. Some intermittent failures may require the use of heat (hair dryer) or cold (freeze mist) to
isolate the failure.
Caution
Care should be exercised to avoid getting components too hot. Excessive heat
may cause permanent damage of good components. Also, avoid spraying freeze
mist directly on PC boards. Failures due to high-resistance paths between
traces on PC boards have been caused by spraying the boards with freeze
mist.

Scan
Generator,
Circuit
Description
The Al6 Scan Generator provides tuning voltage ramps to the IF-Display Section (SCAN
OUT and AUX OUT) andscaled ramps to the AlOA8 PLL2 Discriminator and A19 DAC.
The SCAN OUT ramp to the IF-Display Section is used for the horizontal sweep signal for
the CRT display update, and the AUX OUT ramp is used by the
A4Al
Video Processor to
maintain video information in proper correlation with the horizontal sweep and frequency
tuning.
The scaled ramp to the AlOA8 PLL2 Discriminator is used to scale the tuning current ramp
(VCO TUNE) used to tune the VCO on the AlOA5 PLL2 VCO.
Scan
Time Register
@
and
Sweep
Time
DAC
@
Scan time information is placed in the scan time registers U26, U27, and U29. This
information comes from the front panel via the Instrument Bus. Processing of this
information is done on the Al2 Front-Panel Interface and Al5 Controller. The information is
clocked into the Scan Time Register by control signal LSTS (Low = Scan Time Strobe). This
control signal becomes active (low) whenever the selected scan time is changed. A positive dc
voltage is developed by U8 corresponding to the programmed sweep time information applied
to the DAC U28. This voltage is between
+0.7
V and
+7.0
V.
Ramp
Generator
@
The dc voltage level provided by U8 causes a constant current to flow through the proper
scaling resistor, through Virtual Ground and Q5 to the Ramp Capacitor Cl. The scaling
resistor is selected by the programmed sweep information from the front panel the same as is
the sweep time. This information turns on one of the switch drivers U20A through U20D,
which turns on one and only one of the scaling resistor switches
Ql,
Q2, Q3, or Q4, to place
the proper scaling resistors in the charging current path for Cl. If the selected sweep time
is slower than 200 seconds, none of the scaling resistors are switched in. For 0.0 to 2.5 GHz
frequency span, the waveform on Ramp Capacitor Cl is a positive going ramp from -5.0 Vdc
to -2.0 Vdc with a 3 ms reset time. Ramp Buffer U3 amplifies and shifts the level of the
ramp so that the SCAN OUT is a 0.0 to
+lO.O
V dc ramp.

The sweep ramp is formed by alternately charging and discharging Cl, according to the
following cycle.
Control line HSWP resets the sweep (High = Sweeping). When HSWP goes low (determined
by IF-Display Section), LHOLD (U5C pin 8)
g
oes low, turning on
CRl.
When CR1 is on,
charging current bypasses ramping capacitor Cl and instead passes to ground via
CRl.
Ramping capacitor Cl stops charging.
Ramping capacitor Cl holds its charge until LANR, from Front-Panel Interface Assembly
A12, goes low (Low = Analog Reset). When LANR goes low, LHOLD goes high, turning
CR1 off, removing the current bypass for ramping capacitor Cl. RESET/GO (U5D pin 11)
also goes high when LANR goes low, which turns
Q9
off. Q7 and Q6 then turn on, providing
a discharge path for Cl through Ramp Reset Amplifier U2. Test point 3 remains at ground
potential until HSWP again goes high, starting the cycle again.
Frequency

Register
(ij
and
Span
Width
DAC
@
The Span Width DACs U17 and
UlO
provide a negative scan ramp to be scaled by the
Integer Number Attenuator. The output of this negative-going ramp is between 0 and -10
V. The amplitude of the ramp is dependent on the span of the instrument. Frequency span
information arrives on the Instrument Bus and is stored in registers
Ul
and U18. This
information is clocked into Frequency Span registers U16 and U18 whenever control line LSAS
(Low = Scan Attenuator Strobe) goes low.

@,

@I
The Integer Number Attenuator scales the negative ramp at TP5 to the harmonic band being
swept. This division is by
l/2
for Band C,
l/3
for Band D, and
l/4
for Band E. In Band B,
the ramp is not scaled so it remains unchanged.
The division is performed by R48 through R50. If in Band B, only R80 is in the circuit. In
Band C, R81 is added. In Band D, R82 is added. In Band E, R83 is added. These resistors
are switched in by transistors Q15, Q13, and Q14, which are driven by drivers U19A, U19C,
and UlOB respectively. The information necessary to determine when and which resistors to
switch in comes form the Al2 Front-Panel Interface (SAT 1 and SAT 2) and is decided by
Band Decoder P.

and
Aux
Out
Amplifier
@I
The AUX OUT signal is a positive-going ramp voltage from the scan generator which is
amplified by U9B. This output is always 0 to
+lO
V regardless of the selected frequency span.
If more than one harmonic band is swept, there is a small ramp output from the ramp
generator E (TP3) for each band with each ramp resetting to 0 V. To combine these ramps,
Aux Out Offset DAC U22 and U9A provide a voltage to hold the Aux Out Amplifier input at
a dc level at the end of each ramp. The output therefore is a continuous ramp voltage from
0 to
+lO
V. This voltage is programmed into the DAC U22 by the span information from
the Instrument Bus. This information is stored in Aux Out Register U23 and U21, being
clocked in by control line LAOS (Low = Aux Out Strobe). This control line is from the Al2
2 Al6
Front-Panel Interface and is enabled (pulled low) whenever front-panel key selections indicate
that more than one harmonic board is being swept.
Voltage
Reference
@
Voltage Reference U7 and associated circuitry provide a stable -7 V dc reference voltage for
both the Sweep Time and Aux Out Offset DACs.
Scan
Test
Circuit
@
The control signal HSWP (High = Sweeping) is normally pulled low indicating the end of a
sweep by the
A3Al
Trigger in the IF-Display Section. This signal can also be pulled low by
the Scan Test Circuit for the purpose of testing the scan circuitry.
If the scan ramp should exceed
+ll
V, this overvoltage is detected by
UllD
which triggers
one-shot multivibrator U6. U6 generates a 50 ms pulse on the HSWP line. When this pulse
goes low, the Al5 Controller “thinks” that the sweep has ended and performs its update
functions. When the pulse goes high again (after 50 ms), the Al5 Controller “thinks” a new
sweep has begun. This enables the sweep circuitry to function without the IF-Display Section,
or when a circuit malfunction exists, thus aiding troubleshooting.
Scan
Reset
Amplifier
@
The Scan Reset Amplifier supplies negative feedback that holds SCAN OUT (Q12 emitter) at
ground potential during retrace.
For Scan Generator (HP part number 85660-60198): Fixed-gain amplifier U13 amplifies
any potential at its noninverting input, pin 3. During retrace, LSAMPLE is low, and
sample-and-hold device U14 tracks the U13 output, charging C20.
This error voltage at
C20
is divided by R64, R65, and R66, and is summed with the Span
Width DAC output at U12 pin 2. The amplified and inverted output of U12 cancels the
potential at SCAN OUT that produced the error voltage across C20.
When the sweep commences,
HSWP
and LSAMPLE are high. The input to U14 is held on
C20
for the duration of the sweep.

Al7
Positive
Regulator,
Circuit
Description
Al?
Positive Regulator provides
+20
V,
+12
V, and
+5.2
V regulated voltages to the
instrument. It also provides for thermal shutdown at temperatures above 85°C or if the fan
fails, controls power to the oscillator in the A22 10 MHz Frequency Standard and ensures
power-up and power-down operation that will not invalidate data in Al5 Controller. The
relationship of Al7 to A8 Rectifier, A23 Motherboard, and Al8 Negative Regulator is shown
on the A8 Rectifier schematic.
Front-Panel
Shutdown
@
When the front-panel LINE switch is in STANDBY, the LSBY line is grounded, fan relay
Kl
on the A23 Motherboard is energized turning the fan off, and the STANDBY LED is turned
on.
Pin 9 of U3C is also at ground when LSBY is grounded so the output of U3C is at i-10 V,
turning on
Qll
through R41.
Qll
sinks all of the current supplied by the compound current
source
Ql
and Q2, which turns off the i-20 V supply series-pass transistor A23Q3, located on
the A23 Motherboard. All other supplies are referenced to the output of the $20 V Regulator,
so they are also disabled. (The
+22
V supply is an exception. It is always on as long as the
instrument has ac power from the line.)
When the front-panel LINE switch is switched to the ON position, the LSBY line is no longer
grounded, the fan relay
Kl
is no longer energized, and the fan turns on. LSBY rises to about
+22
V through the fan relay coil. This causes the output of U3C to go low, turning off
Qll.
The current source of
Ql
and
Q2
can now supply current to A23Q3 on the A23 Motherboard,
and the
-j-20
V supply will turn on.
Thermal
Shutdown
@
U3D senses the voltage across thermistor
RTl.
The resistance of
RTl
is nominally 1000 ohms
at 25°C and drops to 107 ohms at 85°C. When the resistance drops, the output of U3D rises,
turning on the thermal shutdown LED DS3 and also Q12, which disables the current source in
the
+20
V supply, shutting the supply off. CR5 and R52 provide hysteresis so the instrument
will not turn on again until the temperature drops to 55°C.
Al7 1
+20
V
Regulator
@
The
+20
V supply has as its reference a 6.2 V zener diode VR2 biased from the output of
the j-20 V supply,
@
on the schematic. The
+20
V output is divided down by R9, R50,
and
RlO to 6.2 V. This voltage is compared with the
t6.2
V reference voltage by amplifier
Ul.
This amplifier sinks current from the current source
Ql
so that the voltage at the base of the
series-pass transistor A23Q23 (on A23 Motherboard) is such that the output of the supply is
at
+20
V.
A simple form of
foldback
current limiting is provided by the current sensing resistor R3, R4,
R5, CR4, and Q3. 0vervoltage protection is provided by the
+20
V crowbar
@
consisting of
VR3 and
CRl.
DS2 is an LED which indicates the presence of an output voltage. Fuse F2
provides further protection for the supply.
+20
V
Switched
Supply
@
The
+20
V switched supply provides power to the oscillator circuits of the A22 10 MHz
Frequency Standard. If the Reference Disable line HSTD is low,
QlO
is off, and
Q9
is off, so
no power is supplied to the internal 10 MHz oscillator. When HSTD goes high, both
Q9
and
QlO
turn on, and i-20 V is supplied to the internal 10 MHz oscillator.
+12
V
Regulator
@
The i-12 V supply is a 12 V floating regulator with its reference terminal biased at 11 V by
R24 and VR8. This supply is enabled by the presence of the -5.2 V supply, which causes
QS
to turn off, allowing the zener diode VR8 to be biased by the current flowing from the output
of the supply through R24. LED DS4 provides a visible indication of an output voltage.
Overvoltage protection is provided by the
-l-12
V crowbar
0.
The regulator itself is internally
protected, but further protection is provided by CR3 and
Fl.
+5.2
V
Regulator
@
The operation of this supply is similar to that of the
+20
V supply. Its reference is from the
voltage divider R36 and R49 from the i-20 V supply. This voltage is compared with the
divided down output voltage by U2, which drives the Darlington-connected transistors Q6
and Q4 and the series-pass transistor A23Q4 on the A23 Motherboard.
Foldback
current
limit is provided by R27-29, R31, R32, and Q5. The output crowbar
@
provides overvoltage
protection. Further protection is provided by F3.
Power
Up/Down
Detector
@
A power-up indication HPUP is provided to allow the instrument to turn on and off in an
orderly manner. The HPUP line goes high when all of the following conditions are met:
1. The rectified dc voltage of the
+5.2
V Unreg supply is above 8.6 V (provides an indication
that the Line Voltage is present).
2. The
t5.2
V output is higher than
t4.9
V.
3. The front-panel shutdown and thermal shutdown circuits allow the instrument to be turned
on.
If both the front-panel shutdown and thermal shutdown transistors
Qll
and Q12 are
off, CR11 is reverse biased. If the output of the i-5.2 V supply is greater than i-4.9 V,
2 Al7
the output of U3A is high, and CR12 is reverse biased. If the dc input voltage to the
+5.2
V supply is greater than
+8.6
V, then the voltage at pin 5 of
U3B
is greater than
+6.2
V, and the output of
U3B
is high. This turns on transistors Q13 and Q7, pulling
the collector of Q7 to about
+5
V. This provides the HPUP signal.
If any of the above conditions are not met, HPUP remains low. R59 and Cl4 provide an
additional time delay at turn-on to allow the supplies to settle down.

Al8
Negative
Regulator,
Circuit
Description
Al8 Negative Regulator provides -5.2 V, -10 V, and -40 V regulated voltages to the
instrument. All three supplies derive their reference from the
+20
V supply on the Al7
Positive Regulator. The relationship of Al8 to A8 Rectifier, Al7 Positive Regulator, and A23
Motherboard is shown on the A8 schematic.
-10
V
Regulator
@
The -10 V supply is referenced to the
+20
V supply by a resistor divider consisting of R5,
R6, and R7 connected between the two supplies. The voltage at the junction of R5 and R6 is
nominally 0 V. Any error is amplified by U2 to drive the series-pass transistor
A23Ql.
The
entire unregulated portion of the supply, including the rectifier diodes and filter capacitor, is
floating; thus the collector of
A23Ql
is typically i-15 V. Current-sensing resistors Rl and R23
are connected between the emitter of
A23Ql
and ground. These resistors, along with R2, R3,
CRl,
and
Ql,
form a current
foldback
protection network.
Overvoltage protection is provided by the -10 V crowbar
BJ
consisting of VR2 and CR26.
Further protection is provided by fuse F3. LED DS2 indicates the presence of an output
voltage.
-5.2
V
Regulator
@
The -5.2 V supply is also referenced to the
+20
V supply by a resistor divider consisting of
R37, R38, and R39 connected between the two supplies. This supply is a double-regulated
supply, as its input is in the regulated output from the -10 V supply. Error amplifier
Ul
drives the pass transistor Q2 via Q3. R32 and R33 are dropping resistors, so the power
dissipation in
Q2
is not excessive. R34, R12, R32, and Q4 provide current
foldback
protection.
Further protection is provided by
Fl.
Overvoltage protection is provided by the -5.2 V
crowbar
@I
consisting of VR4 and CR27. LED DS3 indicates the presence of an output
voltage.
-40
V
Regulator
The -40 V supply is referenced to the
+2OV
supply by the voltage divider consisting of R24,
R25, and R26, designed so that the input to the error amplifier U3 is at 0 V. The output
of the error amplifier drives the Darlington connection of
Q5
and the series-pass transistor
A23Q2. The input to the supply is floating, so the collector of A23Q2 is typically at
+lO
V.
Foldback
current protection is provided by R17, R18, R19, and Q6. Further current protection
is provided by the -40 V crowbar
@
consisting of VR3 and CR25. The presence of an output
voltage is indicated by LED
DSl.

Digital-to-Analog
Converter
(DAC),
Circuit
Description
The A19 DAC provides the tuning voltage to the A20 YTO Main Coil Driver used to coarse
tune the YTO Start Frequency and set the proper amount of sweep. This occurs at the
beginning of each sweep and at the beginning of each harmonic band within a sweep.
YTO
Pretune Register
@
and
Pretune
DAC
@
Frequency information is loaded into pretune registers U5 and U6 from the Instrument Bus.
This is coded information from the Instrument Bus. This information is clocked into the
registers by LDAS (Low
=
DAC Strobe). The Pretune DAC, in conjunction with U2, provides
an output of 0.0 to
i-12.6
V dc in approximately 3
mV
increments. The exact voltage is
dependent on the coded information input. This voltage is applied to Summing Amplifier U4
through R3.
Frequency
Span
Register
and
Switch
Driver
@I
and
Span
Scaling
@
Coded span information from the Al2 Front-Panel Interface is loaded into register U7 from
the Instrument Bus and clocked out to switch drivers U8 and
U9
by LSAS (Low = Scan
Attenuator Strobe). These switch drivers turn on (close) switches
Q2
through Q6 according to
the coded information input. The SCAN DAC IN signal (attenuated sweep ramp) from the
Al6 Scan Generator is then applied to the proper scaling resistors R26 through R30, R38, and
R58, to provide the sweep for the YTO. This output current is applied to Summing Amplifier
u4.
Summing
Amplifier
@
The fixed dc current from the Pretune DAC, corresponding to the desired YTO Start
Frequency, and the ramp current from the Scaling Resistors, corresponding to the desired
Frequency Span, are summed at the input of U4. U4 amplifies this combined signal and
applies it to both the YTO and YTX at a sensitivity of -3
V/GHz
to coarse tune the
analyzer to the selected Start Frequency and Frequency Span.

Main
Coil
Driver,
Circuit
Description
The A20 Main Coil Driver produces a tuning current proportional to the tuning voltage input
from the A19 DAC and applies it to the
AllA
YTO. Th’
is
provides coarse tuning of the
YTO frequency and sweep. Fine tuning is performed by summing a current proportional to
the low-frequency error voltage from the
AllA
YTO Phase Detector (via the A21 FM Coil
Driver) with the tuning current from the A19 DAC. Additional fine tuning is done by the A21
FM Coil Driver using the current proportional to the high-frequency error voltage component.
Input
Amplifier
@
Transistors
QS
through
Ql2
form a discrete noninverting operational amplifier whose output
is proportional to the tuning voltage input (YTO TUNE 1). This output is applied to Coil
Driver
Ql,
Q4, and Q5 which supply the YTO Main Coil current. For frequency spans greater
than 5 MHz, LYSP
(1
ow
= YTO span) turns on (closes) switch
Q2
allowing a current flow
through R19. This is done to improve sweep linearity for wide spans
(>5
MHz).
Phase
Lock
Amplifier
@
Phase Lock Amplifier
UlB
provides a current proportional to the low-frequency error voltage
input (YTO TUNE 2). Th’
is
error voltage input is from the
AllA
YTO Phase Detector and
is indicative of the YTO frequency error. The current output of the Phase Lock Amplifier is
summed with the current output controlled by the Input Amplifier in the Coil Driver.
Coil
Driver
@
Transistors
Ql,
Q4, and Q5 provide drive current to the main coil of the
AllA
YTO to set
the frequency and amount of sweep of the YTO. YTO main coil sensitivity is approximately
25 mA/GHz. The Coil Driver output is between approximately 50 and 150 mA.
Shaping
Network
@J
Compensation network U2 provides linearity shaping of the current output of the Coil Driver.
The components of the network are factory selected to match the YTO. Resistors R24,
Rl6,
and R25 sense the current output of the Coil Driver. R25 is used to fine tune the YTO to
6.15 GHz.
Offset Reference
6~
The Offset Reference composed of
UlA
and associated circuitry provides a fixed voltage to
Phase Lock Amplifier
UlB.
This voltage provides the current necessary to fine tune the YTO
to 2.3 GHz.

A20 Main Coil Driver Component Locations, 85660-60206
A21
A21
FM
Coil
Driver,
Circuit
Description
The A21 FM Coil Driver performs two functions.
1. Separates the low-frequency component from the error voltage input (DET IN) and directs
it to the A20 Main Coil Driver.
2. Provides drive current to the FM Coil of the YTO proportional to the high-frequency
component of the error voltage input (DET IN).
Phase Detector Buffer
@
This buffer drives both the low-frequency
(<lOO
Hz) portion of the error voltage input (DET
IN) to be applied to the A20 Main Coil Driver and the high-frequency portion to be applied
to the FM coil of the YTO.
100
Hz
High-Pass
Filter/Amplifier
@
This filter/amplifier separates the low-frequency (<lOO Hz) signals from the input to be
applied to the main coil of the YTO and amplifies the high-frequency signals to be applied to
the FM Coil of the YTO.
Bias
Stabilization
@
This circuit adjusts the dc current in Buffer
@
to ensure there is not quiescent current applied
to the YTO FM Coil.
Output
Amplifier
@
Ql
and Q4 form a push-pull amplifier to provide drive current to the YTO FM Coil
porportional to the high-frequency error voltage input (DET IN). This is done to tune the
YTO frequency to a corrected output determined by the YTO Phase Lock Loop.
Matching
Network
@
Provides impedance matching between the Output Amplifier and the YTO FM Coil to assure
accurate tuning of the YTO frequency.

MHz
Frequency
Standard
The 10 MHz Frequency Standard provides a stable frequency reference signal for the 100 MHz
Reference Loop to phase lock to. The 100 MHz Reference Loop
(A7Al
Reference Phase
Detector and A7A2 100 MHz VCXO) in turn provides stable frequency reference signals
of 10 MHz, 20 MHz, and 100 MHz to lock the remaining phased locked loops-A7 M/N
Reference, A10
20/30
Synthesizer, and A6A9 Phase Lock.
Alternately, the rear-panel FREQ REFERENCE jumper cable can be removed and
an external 5 Mhz or 10 MHz reference signal can be connected to the EXTERNAL
FREQUENCY REFERENCE INPUT. The performance of the spectrum analyzer will be
degraded unless the frequency reference phase noise and spurious signals are less than -140
dBc single sideband (1 Hz) referred to 10 MHz at a 100 Hz to 10 kHz offset.
The
A22Al
Regulator Board assembly provides
+12
V regulated voltage to the A22A2 Quartz
Crystal Oscillator. Voltage Regulator IC,
Ul,
provides
+12
V resolution with Cl and C3
providing compensation and CR1 providing reverse-bias protection.
The A22A2
Q
uartz Crystal Oscillator is an extremely stable, compact, low-power source of
10 MHz. It has a very fast warm-up time, exhibits excellent temperature characteristics, and
has low phase noise and power consumption.
The A22A2 Quartz Crystal Oscillator has the ability to be adjusted over a range of 20 Hz
(2 x 10w6), yet the control is sensitive enough to allow adjustment to better than 0.1 Hz
(1 x
10-8).

Within the USA, Hewlett-Packard can supply parts through a direct mail-order system.
Advantages of using the system are as follows:
1. Direct ordering and shipment from the Hewlett-Packard Parts Center in Mountain View,
California.
2. No maximum or minimum quantity requirement on any mail order. (There is a
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.
Direct
Phone-Order
System
A phone-order system is available within the USA for regular and hotline replacement parts
service. Hewlett-Packard has provided a toll-free phone number, and accepts Mastercard or
Visa for orders.
Regular Orders
The toll-free phone number is (800) 227-8164. It is available 6 am to 5 pm (Pacific time),
Monday through Friday. Regular orders require a four-day delivery time.
Hotline Orders
The hotline service for ordering emergency parts is available 24 hours a day, 365 days a
year. There is an additional charge on hotline orders to cover the cost of freight and special
handling.
