OPERATING INSTRUCTIONS
INTRODUCTION
Description
The PG 506 Calibration Generator is designed to
operate in a TM 500 Series PowerModule. Theinstrument
is a combination Amplitude Calibrator and Square Wave
Pulse Generator intended for calibration and adjustments
of oscilloscope amplifier systems with a 50 f2 or 1 Mil
input resistance .
The Amplitude Calibrator function provides either a +
do voltage or a 1 kHz square-wave output, as selected by
an internal switch . Peak-to-peak amplitudes from 0.2 mV
to 100 V across a 1 Mfg load and amplitude of 100 mV to
5 V across a 50 f2 load are available. Output amplitudes
are selected in a 1,2,5 sequence .
Because errors are often stated as a percentage, an
internal digital differential voltmeter with front-panel lightemitting diode (LED) readout is used to provide a display
equal to oscilloscope vertical or horizontal deflection
errors . If the indicated deflection on an oscilloscope
graticule does not agreewith the proper reference line, the
output amplitude from the PG 506 Amplitude Calibrator
can bevaried untiltheproperalignmentisobtained . Inthis
operating mode, the front-panel readoutisadirectdisplay
of the oscilloscope deflection error.
A 5 mA Current Loop is provided, which supplies
current (dc or 1 kHz) for calibration of current probes.
The Pulse Generator provides three square-wave outputs : variable High Amplitude pulses and simultaneous
positive and negative-going Fast Rise, variable-amplitude
pulses . In the Pulse Generator mode, the Period is
selectable from 1 ps to 10 ms in decade steps. A variable
control extends the maximum period to at least 100 ms
(for each decade step, the period is variable over a 10:1
range) . A positive going pretrigger output isalso provided
for triggering external equipment.
Installation and Removal

WARNING
Dangerous voltage may be present on the frontpanel BNC connector labeled AMPL OUTPUT
(HIGH or STD). Before installation, turn the control
tabled AMPLITUDE (VOLTS INTO 1 Mfg) fully
counterclockwise (ccw) and the control labeled
PULSE AMPLITUDE to MIN.
Align the upper and lower groove of the PG 506 chassis
with the upper and lower guides of the selected compartment .Push the module in and press firmly to seat the
circuit board in the interconnecting jack .
To remove the PG 506, pull on the release latch located
in the lower left corner until the interconnecting jack
disengages and the PG 506 will slide out.
Preliminary Checks
Make all desired connections to equipment under test
before applying power to the PG 506. The power switch is
on the Power Module . Power application to the PG 506 is
indicated by the PERIOD light turning on, or the light
behind the knob skirt of the AMPLITUDE control switch
being lighted.
The front-panel LED can be tested (888 display) by
setting the three-position Mode switch to STD AMPL
position, then pushing and holding the VARIABLE knob
concentric with the AMPLITUDE switch .
To test the digital voltmeter system, release the
VARIABLE knob to the out position and rotate the control
in both directions .
Allow 15 to 20 minutes warmup time for all equipment
before using the PG 506.
AMPLITUDE CALIBRATOR MODE
Connections and Terminations
To use the PG 506 Amplitude Calibrator system,setthe
mode switch to the STD AMPL position . Connect the
1 kHz calibrated amplitude signal at the AMPL OUTPUT
connector to the input of an oscilloscope through a
coaxial cable that has a 50 f2 characteristic impedance
(RG-58/U) with a maximum length of 42 inches (shorter
cables can be used).
With a cabletermination of 1 Mfg and the DEFLECTION
ERROR display off, the 1 kHz signal peak-to-peak output
amplitude will be equal to the indicated reading on the
AMPLITUDE switch . If the cable is terminated into a 50 f2
load, use an output amplitude in the 10 V to 0.2 mV range;
the output amplitude will then be one-half the indicated
reading on the AMPLITUDE switch .
Oscilloscope Controls
The deflection factor (either vertical or horizontal) for
oscilloscopes is the ratio of the amplitude of the input
signal to the amount of beam deflection produced on the
cathode-ray tube (crt), usually stated as volts per division
of deflection (Volts/Div) . Calibration procedures for some
oscilloscopes require that the gain be set and the deflection accuracy be checked with a probe (properly compensated) connected between the PG 506 and the oscilloscope input connector.
For oscilloscope gain adjustments and checking of
deflection accuracies, it is always best to set all oscilloscope controls exactly as called out in the calibration
and performance sections of the oscilloscope instruction
manual . However, it may be found desirable to set the
oscilloscope sweep controls to a 0.1 ms/div (or faster)
sweep rate and free-run the sweep when performing
vertical deflection (amplitude) checks and adjustments.
This procedure produces two horizontal traces that are
separated vertically by an amount proportional to the
Peak-to-peak amplitude of the 1 kHz square-wave from
the PG 506. At faster sweep rates, the display becomes
more readable.
Deflection Error Readout
When performing gain adjustments on oscilloscope or
amplifier systems, it is mandatory that the DEFLECTION
ERROR readout be turned off in ordertoobtaincalibrated
output amplitudes . The PG 506 DEFLECTION ERROR
readout feature finds its greatest use in its ability to allow
an operator to verify the oscilloscope deflection accuracy
associated with amplifier gain and input attenuators .
Operating Instructions-PG 506 (SN 8040000 & up)
Gain adjustments for oscilloscope amplifiers are usually made at low levels, for example; at a 10 mV/div
deflection factor and a 50 mV signal from the PG 506. This
ratio corresponds to five major graticule divisions of beam
deflection . If the gain of the oscilloscope amplifier system
is low, the indicated deflection will be less than five major
graticule divisions, for example; 4.8 major division . The
VARIABLE AMPLITUDE (OUT) control on the PG 506 can
then be used to increase the output amplitude until the
total deflection is exactlyfive major divisions. Atthis point,
the DEFLECTION ERROR readout will read 4.0% LOW.
Conversely, if the oscilloscope amplifier system gain is too
high, the indicated deflection on the crt will be above the
proper reference line, for example; 5.2 major divisions.
Using the VARIABLE AMPLITUDE control on the PG 506
to reduce the output ampliutde for exactly five major
divisions of deflection will produce a DEFLECTION
ERROR readout of 4.0% HIGH .
For some oscilloscopes the deflection factor may not
be constant throughout the full vertical dimensions of the
graticule, dueto compression or expansion nonlinearities.
To check for this type of nonlinearity ; center a twodivision display, then position the display to the top of the
graticule. Measure any deflection errors with the PG 506
VARIABLE AMPLITUDE control . Next, position the twodivision displaytothe bottom of the graticule and measure
the deflection errors . These nonlinearities should betaken
into account when making measurements with full
graticule deflection, or with the crt trace positioned
towards the top or bottom graticule limits and using small
deflection factors.
Current Loop
One end of the Current Loop is grounded and terurinates a precision voltage divider. The direction of the
arrow is oriented for conventional current. To obtain a
calibrated 5 mA from the Current Loop, set the mode
switch to STD AMPL position and the AMPLITUDE
control switch to the 100 V position . The DEFLECTION
ERROR readout should be off, or adjusted to read 0.0%.
The current signal can be either do or 1 kHz square-wave
current, as selected by an internal switch .
PULSE GENERATOR MODE
General
In order to ensure waveform fidelity when using the
Pulse Generator function of the PG 506, the following
precautions should be observed .
1. Use high quality 50 O coaxial cable, connectors,
and terminations (where applicable) . Make all connec
tions as tight and short as possible .
2. Reduce capacitive and inductive loads to a
minimum . Risetime degradation occurs with long cable
lengths.
3. Minimum risetime and pulse aberrations are obtained with 50 O loads and loads must be capable of
dissipating the power available at any output connector in
any operating mode.
4. The external equipment is assumed to have no do
voltage across the load to which the PG 506 is connected.
If a do voltage exists, the output amplitude from the
PG 506 will be in error by the amount of the do offset . To
prevent dc-offset errors, couple the PG 506 outputs
through a do blocking capacitor to the load . The time
constant of the coupling capacitor and thetotal resistance
in series must be long enough to maintain pulse flatness .
High Amplitude Output
To use the PG 506 Pulse Generator system to produce
high amplitude square-waves, set the mode switch to
HIGH AMPL position and connect external equipment to
the AMPL OUTPUT HIGH connector. Set the Period
controls for the period or frequency desired. The output
amplitude of this signal can be adjusted with the PULSE
AMPLITUDE control .
This signal can be used to adjust oscilloscope amplifier
input capacitance, attenuator compensation networks,
and other internal frequencycompensation networks . The
AMPL OUTPUT HIGH signal is negative with respect to
ground, with its risetime related to the rising portion (from
a negative potential) of the waveform . Refer to Fig. 2-3.
The absolute peak-to-peak value of the square-wave is
determined by the load resistance and the setting of the
PULSE AMPLITUDE control . Table 2-1 lists the typical
amplitudes available when the PG 506 is terminated into
three different load resistances .

keep system errors to a minimum.

Fast Rise Outputs
To use the PG 506 Pulse Generator system to produce
low amplitude, fast-rise square-waves, set the mode
swtich to FAST RISE position and connect external
equipment to the FAST RISE OUTPUTSconnector(s) .Set
the PERIOD controls for the period or frequency desired.
The output amplitude can be adjusted by the PULSE
AMPLIUTDE control .
These signals are usually used to adjust highfrequency compensation networks in oscilloscope
amplifier circuits . The adjustments are made for optimum
response (minimum aberrations) . The risetime and
amplitude specifications for the FAST RISE outputs apply
only when they are terminated into a 50 f2 load . Larger
amplitudes (greater than 1 V peak-to-peak) can be obtained from these output connectors under unterminated
conditions, but the risetime specification is no longer
applicable .
GENERAL INFORMATION
Risetime Considerations
The PG 506 can be used in conjunction with an
oscilloscope to determine the risetime of a device under
test . Risetime is normally measured (unless otherwise
specified) between the 10% and 90% amplitude levels on
2- 6
Before measuring the risetime of a device under test,
the combined risetime of the PG 506 output signal and the
oscilloscope vertical amplifier system must be known.
Refer to Fig. 2-4 for the percentage error to be expected
when the two devices are cascaded. Sweep timing accuracy should be verified before any risetime measurements are made . Inaccuracies in the sweep timing and
display reading errors must be added algebraically to the
percentage error obtained from computations related to
Fig. 2-4.
2. Conversely, if the signal risetime is at least seven
times faster than the risetime of the oscilloscope vertical
system, the displayed (observed) waveform will have a
risetime that is very close to the risetime of the vertical
system .
3. The displayed risetime as observed on any oscilloscope can never be faster than the risetime of the
slowest device in the system .
Risetime of a displayed waveform is related to total
system bandwidth. A system with limited high-frequency
response will produce a displayed risetime that is slower
than expected . If a fast-step signal produces a crt display
with little or no overshoot or ringing, the product of
oscilloscope risetime and oscilloscope bandwidth should
result inafactorwhosevalueliesbetween0 .329and0 .350 .
The following steps describe the procedure tofollowin
determining the risetime of a device under test .
1 . Connect the appropriate output signal from the
PG 506 to the oscilloscope vertical input withashort50 f2
coaxial cable terminated into a 50 S2 load .
2. Set the oscilloscope controls to display the leading
edge of the waveform . Risetime measurements should be
made over the largest part of the graticule area possible.
When the fastest sweep rate is relatively slow compared
with the vertical system risetime (or the scale is small),
measurements become confined to small sections of the
graticule, and the probability of display reading errors
becomes greater.

Checking Amplifier Response
The square-wave output signals from the PG 506 can
be used to check the response of active or passive systems . Because the characteristics of a pulse from the
PG 506 is known (see ELECTRICAL CHARACTERISTICS), distortion of the waveform beyond these limits is
due to the device under test .
The compensation of an ac-voltage divider, such as
used in the input attenuator of an oscilloscope or a passive
attenuator probe, can be checked by observing its
response when a square-wave signal is applied. Correct
response is shown by optimum square corner on the
displayed waveform . If the waveform has overshoot,
rolloff, or front-corner roundi ng, the system is not correctly compensated. Figure 2-5 shows typical waveforms
illustrating correct and incorrect compensation adjustments. When performing these compensation checks,
the repetition rate of the applied square-wave signal
should be at least 3 to 4 decades above the low-frequency
cutoff point (frequency where the equivalent sine-wave
amplitude is 30% down) .

For example; if the applied frequency, Fa, is 10 Hz and the
amplitude values shown in Fig. 2-6 are used, the lower cutoff frequency is calculated to be about 1 .6 Hz.

that may be observed if amplifier circuits are not properly

The low end cut-off frequency (due to RC coupling) for
an amplifier can be approximated very closely by using the
following procedure.
1 . Apply a square-wave at a repetition rate that is not

2. Slowly reduce the square-wave frequency and
adjust the oscilloscope (amplifer) controls to display a

The 120 V do supply is the main power source for the
Standard Amplitude system .
setting of the PULSE AMPLITUDE control and the external load that terminates the PG 506. With a 1 MII (untermianted) load, the do level will be about 3.5 V for the MIN
position and about 20 V for the MAX position .
The + and -16.5 V do supply is the main power source
for the Digital Voltmeter circuitry, the Fast Rise stages,
and two operational amplifier circuits in the Standard
Amplitude system .
Remote voltage sensing to regulate the-72 V variable
supply originates in the High Amplitude circuit and is
applied through CR27 to pin 4 of voltage regulator U20.
The -72 V, variable do supply isthe main power source
for the High Amplitude section. This supply can vary from
about -10 V to about -72 V, dependent upon operating
conditions .
When in the Standard Amplitude or Fast Rise mode, the
junction of L35 and C36 is about 20 V dc, with the -72 V
variable supply disconnected from the High Amplitude
circuitry.
All of the above do supplies are produced by conventional full-wave bridge rectifier circuits that are driven by
an inverter system that changes a do voltage to approximately 25 kHz power in the primary and secondaries
of T130. Each supply is switched on or off, dependent
upon the operating modes.
Voltage regulation fortheStandardAmplitudeand Fast
Rise modes is dependent upon the peak voltage (about
10 V) developed across C75 by the half-wave rectifier
action of CR78, which obtains its ac voltage from a sense
winding of T130 . The peak level across C75 is applied to a
voltage divider composed of R31, R30, and R29. The
quiescent level set on pin 4 of U20 by the adjustment of
R30 determines the quiescent current through the NPN
series-pass transistor . Pin 4 of U20 is the inverting input
terminal for an internal comparator, and any voltage
change on pin 4 causes a voltage change in the opposite
direction on pin 10. A potential difference of 33 .0 V across
the + and -16.5 V supplies is accomplished by adjusting
R30.
Primary Power
The 5.2 V do supply is derived from a 11 .5 V do source
in the power module and is distributed mainly to the
Period Generator, Counter circuits, and certain logic
gates. This supply is also used as a return for the High
Amplitude circuits .
CR10 and CR11, together with C10, convert 25 V ac
(rms) from two transformer secondaries in the power
module to about 35 V dc. VR10 sets and regulatesthe base
voltage of emitter-followerQl5 to about 15 V, establishing
a fixed 14 V supply for the 25 kHz free-running multivibrator (Q90-Q100) .
The free-running multivibrator collector output has a
peak-to-peak amplitude of about 5 V, and the positive
swing is limited to about +5 .8 V by CR86 and CR105. This
signal drives the bases of Q85 and Q120 for the inverter
system . The feedback connections from the collectors of
Q80 and G~125, through CR80 and CR125, ensures that
both transistors are never on at the same time .
The maximum voltage swing at the collectors of G80
and Q125 is about twice the do level established at the
junction of L35 and C36 in any operating mode . For the
High Amplitude mode, this do level is dependent on the
Current limiting for the 35 V do input is controlled by
the voltage drop across R22. If pin 2 of U20 goes about
0.6 V more positive than pin 3, pin 10goes negativeto limit
current through athe NPN series-pass transistor and the
load . CR22 protects a transistor internal to U20. C22
frequency compensates the voltage regulator. VR30 is not
normally on ; it protects tl-~e supply from over-voltage
conditions if the potential difference across it exceeds
12 V.
U20 sets its own reference voltage of about 7 V on pin 6,
with pin 5 being the non-inverting input to an internal
comparator . The reference voltage on pin 6 is divided
down by R40 and R42 to set a reference level of 5.2 V on
pin 2 of error amplifier U50.
Voltage regulation of the 5.2 V supply is accomplished
by comparing the voltage level on pin 3 of U50 with the
Theory of Operation-PG 506 (SN 8040000 & up)
voltage reference on pin 2. If the voltage on pin 3 is higher
than the reference level, the output of U50 goes positive.
This voltage increase is applied through emitter-follower
060 to the base of the PNP series-pass transistor . This
action decreases the current in the PNP series-pass
transistor and the load, returning the 5.2 V supply to its
original level.
essentially at the same potential (9 V) and pin 6 of U200 is
at a quiescent level of about 4 V. The emitter of 0190 will
be at 18 V and this point serves as a regulated voltage
source to power operational amplifiers in the 50 f2 source
section . Because 0190 is included in the feedback loop
around U200, the current through VR210 and R210
remains constant .
VR55 and CR55 operate as current limiting control
devices. The normal operating potential atthe base of 060
is about 9.2 V, with VR55 and CR55 not conducting . If the
load current increases (dueto lower load resistance), pin 3
of U50 goes negative. This drives the base of 060 negative
to about 8.3 V. The action is sufficient to cause VR55 and
CR55 to conduct, clamping the emitter of 060 and the
base of the PNP series-pass transistor to about 9 V. R65
limits the load current to about 1 .5 A.
One mA through R237 and R234setsa9 V level on pin 2
of U240 . Pin 3 of U240 is returned to the 9 V zener
reference through R225A and R215 . With almost equal
potentials on each side of R225A, the current through this
network is in the low mA range. R225A tracks with R225B
and serves only as a variable Thevenin input impedance
for the non-inverting input terminal of 0240, which aids in
stabilizing the offset bias current.
An over-voltage condition of about 1 V on the 5.2 V
supply causes VR45 to conduct, developing an SCR firing
pulse across R45. If 045 turns on, the output level is
clamped to about 0.2 V.
Standard Amplitude
O
The Standard Amplitude system consists of two sections, a high-voltage section and a 50 f2 source section .
Output amplitudes of 100 V, 50 V and 20 V originate
directly from a precision voltage divider composed of
R278, R277, R276, R275, and the 5 mA Current Loop. For
these three output amplitudes, the input to the 50 f2
source section is disconnected and pin 2 of U375 is
grounded through R380 . With pin 2 of U375 grounded, its
output locks the base of 0365 to +16 V, disabling the
current drive for the 50 fl source section.
The Primary Power section applies 120 V to the emitter
of 0280, a 10 mA current source . This 10 mA is split
between two branches containing matched diodes; 5 mA
through CR280A and the precision dividier and 5 mA
throughCR280Bfromthe100Vbus .Inthedcmode,0255
and 0270 are cut off (due to saturation of U255) and the
quiescent level at the anodes of the matched diodes is
about 100.7 V.
With S225 closed, (VARIABLE AMPLITUDE control
pushed in and DEFLECTION ERROR readout off), a 100 V
bus is established across a voltage divider composed of
R237 and R234. The reference source for the 100 V bus
originates with VR210, which produces a 9 V drop when
drawing 7.5 mA through R210 . The 9 V level across R210
also serves as a reference voltage forthe Digital Voltmeter
circuit.
When R205 has been adjusted to produce 100 .OV
across an external 1 Mfg load, pins 2 and 3 of U200 will be
3-2
U240 and the circuitry associated with 0245 and 0290
operate as a voltage regulating circuit for the 100 V bus.
Any voltage change on the 100 V bus is sensed across

operates as a level shifter and signal inversion through
0290 returns the 100 V bus to its calibrated level. CR290
Q29o 8291 operate to limit turn-on surge current through
When the VARIABLE AMPLITUDE control is released
to the out position, R237 is disconnected from ground and
R227 is inserted in series with R225B. The 100 V bus now
becomes a variable level . R225B can adjust the 100 V bus
over a range of approximately 92-108 V, and the
regulating circuit will hold the selected level. The
difference in potential between the adjustable level on the
100 V bus and the 9 V zener reference is applied to the
Digital Voltmeter circuitry for DEFLECTION ERROR
readout (100 V equals 0.0%) .
When the 1 kHz (calibrated amplitude) mode is
selected, a 1 kHz squarewave is applied to the base of
0270 through U255 and emitter follower 0255 . The
Positive step on the base of 0270 saturates this transistor,
pulling its collector below 0.4 V. This action disconnects
CR280A and CR280B, allowing the voltage swing across
the precision divider to start from ground and rise to the
level selected on the variable bus when 0270 is cut off by
the negative step of the 1 kHz signal .
The 50 f2 source section must drive either a 1 Mfg or
50 f2 external load resistance . This requirement is met by
using a constant-current supply; which, by definition, will
alter its output voltage by just the proper amount to
maintain its total output current at a constant value when
the load resistance changes. The 50 f2 source section
operates only when amplitude settings oflOVorlowerare
selected .
Theory of Operation-PG 506 (SN B040000 & up)
A nominal 14 V input to the 50 S2 source section is
derived from the precision divider at the junction of R275
and R276 and applied to pin 2 of 0375 (R380 is disconnected from ground). This input voltage will always be
a do level proportional to the do level established on the
100 V bus. 0375 and 0365 operate as a tracking voltage
source . If the input to U375 changes by 5%,the collector
voltage of 0365 changes by 5% .
The constant-current supply is programmed by
current-setting resistors in series with the emitter of 0325
and the collector of 0365 to produce three selected output
current levels through CR320. Selected calibrated
currents of 200 mA, 100 mA, or 40 mA split between three
branches consisting of R316, the symmetrical pi (ladder)
attenuator network, and the external load . With R340
properly adjusted, three voltage levels (10 V, 5 V, or 2 V)
can be selected to appear across R316 for an external
termination of 1 MS2. With an external termination of 50 S2,
the three selected levels across R316 will drop to 5 V,
2.5 V, or 1 V. Each section of the ladder attenuator divides
by 10 and if the level across R316 is considered to be a
0 dB reference, the total attenuation is 80 dB (20 dB per
section) . The attenuator presents an output impedance of
50 S2 at any voltage take-off point.
Regulation for the constant-current supply is provided
by the operational amplifier feedback connections from
the current-setting resistors low level end through U330to
the base of 0326 . 0320 is cut off for the do mode and
operates as a saturating switch for the 1 kHz mode .
Digital Voltmeter
The Digital Voltmeter circuitry is an analog-to-digital
converter, that operates on the principle of a modified
dual-slope integrating system . A change in input current
to integrator U460 causes a ramp voltageto appear at pin
6. At a given time during the ramp, C462 is discharged by a
reference current of opposite polarity. At the time the
discharge current is applied, a counter is at a count of 200
(00) . When the i ntegrated waveform on pin 3 of differential
comparator U470 (zero crossing detector) reaches zero, a
number in the counter is stored . The accumulated counts
are displayed as being proportional to the value of the
input voltage applied; a higher input voltage means a
longer time to zero crossing, thus a higher count. It takes a
few cycles of dual-slope integration for the analog-todigital convertor system to settle down for a stable
readout.
A non-linear reciprocal relationship exists between the
Standard Amplitude output from the PG 506 and the
actual deflection error of an oscilloscope amplifier
system . Consequently, toindicateadeflectionerrorthatis
6.8% LOW, the output from the PG 506 must be adj usted to
be 7.3% high (variable 100 V bus set to 107.3 V) . For an
indicated deflection error of 7.3% HIGH, thevariable 100 V
bus must be adjusted for 93 .2 V. It is the voltage changes
on the variable 100 V bus that result in a DEFLECTION
ERROR readout.
Assume that the Latch Pulse for the counter has just
occured. The nominal calibrated level (0 .0%) on pin 3 of
U460 is 9 V. A decrease in voltage on the 100 V bus pulls
pin 3 of U470 negative below zero and C462 begins to
charge through R460, producing the first ramp after the
Latch Pulse. During this charge time, the output of U470 is
high and the counter is counting up to a count of 200 (00) .
0475 is turned on and light-coupled through 0480 to the
base of 0480. The collector of 0480 is high, turning on
CR480 and HIGH indicator light DS480.
The system contains two reference current sources; a
+I~ source from the collector of 0415 and a-I~ source from
the collector of 0400 . Only one of these current sources is
switched on at a given time, dependent on the polarity of
the voltage change on the 100 V bus. For a ramp that is
negative, pin 5 of U400B is set high and pin 1 of U400A is
set to a low . Pins 2 and 4 of these NAND gates connect to a
common control line and, while the counter is counting up
to a count of 200 (00), pin 8 of U4000 is at a low level .
During the first ramp period, the output levels of U400A
and U400B are high and both reference current sources
are cut off. See Fig. 3-1 .
When the counter has reached a count of 200 (00), a
negative-going Full Pulse appears on pin 9of U4000. This
Full Pulse switches the common control line (pin 8) to a
high level. Pin 3 of U400A remains high while pin 6 of
U400B goes low, turning off 0410 . 0415 is switched on for
the +I~ discharge current to C462 . The ramp on pin 3 of
U470 switches polarity (runs toward zero) . The counter
begins to accumulate the necessary counts for display.
0435 has been turned on by the Full Pulse and lightcoupled through U535 to the emitter of 0540, cutting this
transistor off.
When the ramp crosses the 0 V level, a negative-going
Latch Pulse occuring on pin 7 of 0470 is transmitted
through C506 and CR502 to pin 13 of U400D. This Latch
Pulse switches pin 8 (common control line) of U4000 to a
low, locking out both reference current sources and
turning off 0535 . A positive-going Latch Pulse appears at
the collector of 0565 to store the count in the countersfor
display. After the Latch Pulse has been produced at zero
crossing, C462 again starts to charge through R460 (ramp
increases in a negative direction) and the cycle repeats.
For input voltages above 100 V, the circuit action is
similar to the action just discussed ; except that the dual
ramps on pin 3 of 0470 are positive, DS482 is turned on for
a LOW indication of DEFLECTION ERROR, and the -I~

capacitor C580 in series with main timing resistors R587,
R590, and R593 . These components set a basic 0.5 ~s
period (2 MHz square-wave signal) for the entire instrument.
Reference currents from both reference sources track
with changes on the 100 V bus and in the same direction,
allowing the instrument to be calibrated directly for
oscilloscope deflection error rather than output amplitude
from the PG 506. The adjustment of R415 calibrates the
HIGH indication, while the adjustment or R425 calibrates
the LOW indication .
The timing capacitor and resistors) have a common
connection at the base of 0580 . The signal on the base of
0580 is basically a linear ramp (with switching transients)
that causes the output level at the collector of 0605 to go
high and low when the ramp crosses the hysteresis limits
of the circuit.
CR395 and CR397 protect components in the DVM
circuitry if the + and -16.5 V input connections are
accidentally reversed .
Period Generator and Display
The Period Generator circuit consists of six transistors
(0575, 0580, 0585, 0595, 0605, and 0610) and timing
Assume that when power is applied, 0575 turns on and
0580 turns off. This action also turns off 0595, setting one
end of the timing resistors to the saturated level at the
collector of 0595 . The base of 0580 now begins a ramp
rundown toward the lower limit of the hysteresis window.
C580 is charging toward a 5 V supply through R582 and
the timing resistors. When the ramp at the base of 0580
crosses the lower limit of the hysteresis window, 0580
turns on and 0575turns off. This actionturns 0585 on and
Theory of Operation-PG 506 (SN 8040000 & up)
0595 off. R593 is now disconnected from essentially a
ground potential and connected to a 5 V supply through
0610. The effective voltage acrossthetiming resistors has
now changed polarity and C580 begins to discharge
because the emitter of 0585 is essentially at zero . The
base of 0580 begins a ramp runup toward the upper limit
of the hysteresis window . When the ramp crosses the
upper limit, 0580 is again turned off and 0575 turned on,
reconnecting the timing resistors to the collector level of
0595 . The voltage swing across R600 (caused by 0580
turning on and off) are inverted by 0605 and applied as
TTL levels to pin 14 of U665 .
0665, U666, U667, and U668 operate as a divide-by-ten
frequency dividers (multiplies input period by ten) with a
0.2 kHz (5 ms) square-wave on pin 11 of U668 and a 5 ~s
(200 kHz) square-wave on pin 11 of U665. Input data for
the counter latch circuits originates on pins 1, 12, 9, 8, and
11 of U666 and U667, respectively . BCD data from the
counter latches (U670-U671) is decoded by U673 and
U675 to drive the seven-segment LED displays (DS700DS702) .
U610A and U6108 are each one-half of a dual J-K
master-slave flip-flop. The input to pin 1 of U610A is
always a 2 kHz signal, obtained from pin 11 of 0667 . Pin 12
of U610 is a 0 terminal and the 1 kHz output signal is used
to drive the diode section of 0255 in the Standard
Amplitude circuitry. To remove the 1 kHz drive to the
Standard Amplitude circuitry when it is not needed, pin 2
of U610A is held low, which sets pin 12 to a logical zero.
The Standard Amplitude circuitry is i n a do mode when pin
2 is grounded by the closure of S660 . For the High
Amplitude mode, pin 2 is grounded through CR661 ; forthe
Fast Rise mode, through CR660. CR656 and CR657
provide ground connections for the PERIOD light when
the PG 506 is used as a Pulse Generator .
The input signals to U610B (as selected bythe PERIOD
control) are obtained from the frequency dividers (pin 11)
or directly from the 2 MHz Period Generator . The period of
the output signals on pins 8 and 9 of U610B are twice the
selected input period . These signals are applied to NAND
gates U615B and U615C to drive the High Amplitude or
Fast Rise circuits . The drive signals on one input terminal
of a NAND logic device are gated through with i nverted
polarity if the other input terminal is held high . The+TRIG
OUT signals are supplied by inverter connections of
U615A and U615D . To remove (lockout) drive signals
through both NAND gates when they are not needed
(Standard Amplitude mode), pin 6 of U610B is held low by
the closure of S180A-5B . This action sets pi n 9 of U610B to
a logical zero (low) and pin 8 to a logical one (high) .
The closure of S180A-7B locks out drive signals to the
High Amplitude circuitry when the instrument is in a Fast
Rise mode ; for the High Amplitude mode, the closure of
S180A-6B locks out signals to the Fast Rise circuitry.
To disable the High Amplitude power supply when
operating in a Standard Amplitude mode, CR616 is
grounded through S180A-5B . When operating in a Fast
Rise mode, CR615 is grounded through S180A-7B .
High Amplitude
The negative-going output, with 0745 and 0758
supplying the current, is developed across resistor R805
and the external load . CR755 and CR756 operate as
disconnect diodes at the 0 V output levels . The specified
reference is the positive-going edge of the output
waveform, requiring that 0745 be switched off for the
output to swing from a negative potential to ground . 0760
serves as a 2 mA current shunt through disconnect diodes
CR766 and CR767. This circuit absorbs the leakage
currents from 0745 and 0758 during transitions and adds
a slight amount of reverse bias to the output disconnect
diodes, improving the risetime and ensuring very sharp
corners for the output voltage swing.
The transistors 0745 and 0758 are connected in
cascode and the voltage transitions at the base of 0745
determines the output current swi ng . A negativetransition
at the base of 0745 requires a negative-going transition at
the base of 0715 to saturate 0730 and cut off the output
current.
The High Amplitude circuitry is floating on a variable
power supply with limits of about -10 V to a maximum of
about -72 V. The collectors of 0725, 0740, and 0790
translate the do (and signal) levels from ground to a
negative supply for the output stages and amplitude
control circuitry. 0790 is a 4 mA current sourcethat floats
the amplitude control circuitry at about 6 V more positive
than the variable supply voltage level .
R736 in the emitter of 0736, along with R746 in the
emitter of 0745, are chosen so that the current into these
nodes isafunctionoftheactualsupplyvoltage .Theactual
current that enters 0745 is controlled by the base voltage
and the voltage drop across R745 . The emitter of 0736 is a
low-impedance driving point that controls the output
current limits . 0736 also temperature-compensates the
base junction of 0745 . The base of 0736 (and the collector
of0782)isconsideredtobeazerotemperaturecoefficient
voltage point.
The PULSE AMPLITUDE control is R785A, located in
the base circuit of 0784 . This control obtains its reference
voltage from across VR790. 0780 and 0784 form a
differential circuit with 0780 connected as a diode for
Theory of Operation-PG 506 (SN 8040000 & up)
temperature compensation . Q736 is driven by Q782,
which adds additional gain tosetthebaseofQ780equalto
the base of 0784 . R784 sets the minimum output current
limit and R790 is adjusted to set a 5.2 V output amplitude
across a 50 S2 load . CR734, connected between the
variable supply and the most negative level of the
amplitude control circuitry, allows an additional 0.7 V
voltage drop across Q780 and Q?82, thereby improving
the amplitude linearity .
in series with the emitters of Q935 and Q995 . A negative
transition occurs at J950 when Q935 is turned off and a
positive transition occurs at J1010 when Q995 is turned
off. Both transistors turn off simultaneously with R935 and
R995 providing return paths for leakage currents . C940
and C1000 are provided to reduce excessive overshoot
and ringing . R940 and R1000 are selected for minimum
aberrations and maximum risetime with an optimum value
of 120 C2 .
The sensing point to regulate any one level of the
variable supply is at the collector of Q790 . A drift in the
supply voltage is level shifted through VR790 and applied
to pin 2 of U840 . CR27 is turned on to control the level at
pin 4 of U20, the voltage regulator in the Primary Power
supply.
Simultaneous amplitude control of the output signals is
accomplished by diverting current from the emitters of
Q935 and Q995 through the series path of Q1036 and
Q1045. The voltage drop across R1040 is controlled by the
adjustable voltage level at the emitter of Q1030, a low
impedance source for the base of Q1036. Q1020 operates
as a current switch to set the collector of Q1030 to about
5 V when the Fast Rise mode is selected . R1025 sets the
minimum amplitude available at the output and R785B
controls the minimum and maximum amplitudes .
The actual voltage of the variable supply is made a
function of the negative peak levels of the output signal .
The negative peaks are sampled through CR800 and
emitter-follower Q800 to store a charge on memory
capacitor C800 . If the output signal amplitude is increase
(larger negative peaks), pin 3 of U840 goes negative . A
negative charge on pin 4 of U840 results in a larger do
supply for the inverter system i n the Primary Power circuit
and the variable supply to the High Amplitude circuit goes
more negative . The net result is that the voltage drop
across the output transistors remains relative constant .
The variable supply tracks with the selected output
amplitude and in the same direction. The emitter of Q745
is connected through VR790 to pin 2 of U840 ; the drain of
Q758 is connected through Q800 to U840 pin 3. Because
an operational amplifier (U840) always attempts to reduce
the voltage difference between its input terminals to zero,
the constant voltage drop across the output transistor
network is essentially equal to the drop across VR790 plus
about 2 to 7 V across other components in the feedback
loop .
Fast Rise
The Fast Rise circuit produces two output signals that
occur simultaneously . Q935 and Q995 operate as nonsaturated current-mode switching sources for the output
signals. CR944 and CR1004 are disconnect diodes that
have very low leakage current characteristics at zero-bias
levels . These levels occur when Q935 and Q995 are cut off.
In order to produce 1 V across a 25 S2 load (50 SZ
termination in parallel with either R950 or R1010) it
requires 40 mA . This current is availablethrough resistors
When the Fast Rise mode is switched off, the + and
-16 .5 V supplies are switched off. The collectors of Q1020
and Q1030 drop to about zero, driving the base of Q1036
negative . This action completely cuts off the leakage
currents that might have existed in the collectors of Q935,
Q1036, Q995, and Q1045 if the collector of Q1030 had
been tied to a fixed 5 V source. This arrangement ensures
that the output connectors rest at a 0 V level with the
instrument is not in a Fast Rise mode .
Q860 and Q862 operate as a Schmitt triggerforthe Fast
Rise circuit, with VR866 providing positive feedback and
Q850 serving as a constant-current source . A positivegoing pulse at the base of 0860 results i n a negative-going
pulse at the collector of Q880 and a positive-going pulse at
the collector of Q890, where the transitions are speeded
up and translated to ground levels by R882 and R892 . At
this point, the signal currents are split into two paths
through differential amplifiers (Q900-Q910 and Q960Q970). For a positive-going input to the base of Q960, the
emitter of Q935 is driven negative by the saturation of
Q920 and the emitter of Q995 is driven positive by the
saturation of Q980 .
CR1062 and CR1067 protect the Fast Rise circuit
components if the wiring plug to the circuit board is
accidentally reversed . The diodes in the base circuits of
Q1030 and Q1045 are for temperature compensation .

Calibration Procedure-PG 506 (SN 8040000 & up)
Adjustment Procedure
ADJUSTMENT PROCEDURE
Introduction
Preparation
This adjustment procedure is to be used to restore the
PG 506 to original performance specifications . Adjustment need not be performed unless the instrument failsto
meet the Performance Requirements of the Electrical
Characteristics listed in the Specification section, or the
Performance Check cannot be completed satisfactorily .
a. Remove the side covers of the PG 506 to gain access
to the adjustments. Pull the rear end of the side cover
outward from the side of the instrument (the cover snaps
into place) .
Completion of all adjustment steps in this procedure
ensures that the instrument will meet the performance
requirements listed in the Specification section. However,
to fully ensure satisfactory performance, it is recommended that the Performance Check be performed after any
adjustment is made .
Adjustment Instructions
The alphabetical instructions under each step (a, b, c,
etc.) may contain Check, Examine, or Adjust as the first
word of the instruction . These terms are defined as
follows:
1 . Check-indicates that the instruction accomplishes
a performance requirement check. Each performance
requirement is derived from the instrument specification
as listed in the Electrical Characteristics in Section 1 .
2. Examine-usually precedes an Adjust instruction
and describes howto determine whetherthe adj ustment is
necessary. Measurement limits following the word Examine are not to be interpreted at performance limits
derived from the instrument specifications. They are
provided as indicators of a properly functioning instrument and to aid in the adjustment process.
3. Adjust-describes which adjustment to useto make
the desired result . We recommend that adjustments not be
made if a previous Check or Examine instruction indicates
that no adjustment is necessary.
Adjustment Interval
To maintain instrument accuracy, check the performance of the Calibration Generator every 500 hours of
operation, or every three months if used infrequently.

Troubleshooting Aids
Refer to the power module instruction manual for a
general discussion of aids in troubleshooting TM 500
Series equipment.
Interface Notes
The following information will aid the user in performing both corrective maintenance and in customizing the
instrument .
Pin Assignments. Besides those pins used to connect
the PG 506 to the power module (1-15, A & B), other pins
are available to output signals to the interface so that they
may be connected to other plug-ins through the interface.
Fig. 5-1 shows the pins and their assignments.
CA UTION
When specialized rear interface wiring has been
added to a Power Module compartment, the PG 506
may not be fully compatible with all other members
of the signal source family. Trigger output (278 and
288) and main output (28A and 27A) are compatible,
as is the ground on 268. The ground on 22A is not
compatible with certain instruments, nor is the bcd
information on 178 through 248 and the HIGH-LOW
output on 168 . A plastic barrier (Tektronix Part
Number 214-1593-02) should be installed in the key
slot between contacts 23 and 24 on the power
module . However, before inserting any ocher
TM 500 signal source in a compartment with PG 506
interface wiring, check the diagrams in this book for
pin-by-pin compatibility. Likewise, do not insert a
PG 506 into a slot with rear interface wiring for any
other signal source family connection without making fhe same compatibility check.

MSD & LSD Outputs. To obtain readout information at
the interface, use flat ribbon-wire to connect this digital
informationtothethrough-plated holes asshownin Fig. S2 and according to the following list :
MSD A to 248
MSD B to 238
MSD C to 228
MSD D to 21 B
6 lead flat ribbon-wire
ponents. Servicing static-sensitive assemblies or
components should be performed only at a static
free work station by qualified service personnel .
4. Nothing capable of generating or holding a static
charge should be allowed on the work station
surface.
5. Keep the component leads shorted together
whenever possible .
LSD A to 208
6. Pick up components bythe body, never bythe leads.
LSD B to 198
7. Do not slide the components over any surface.
LSD C to 188
8. Avoid handling components in areas that have a
floor or work-surface covering capable of
generating a static charge.
LSD D to 178
3 lead flat ribbon-wire
9. Use a soldering iron that is connected to earth
ground .
Hi-Lo to 168
NOTE
10 . Use only special antistatic suction type or wick type
desoldering tools.
Each of the MSD and LSD outputs is only capable of
driving one TTL load. The active level of each output
is high .

Static discharge can damage any semiconductor
component in this instrument.
This instrument contains electrical components that
are susceptible to damage from static discharge. See
Table 5-2 for relative susceptibility of various classes of
semiconductors . Static voltages of 1 kB to 30 kB are
common in unprotected environments .
Observe the following precautions to avoid damage :
1. Minimize handling of static-sensitive components .
2. Transport and store static-sensitive components or
assemblies in their original containers, on a metal
rail, or on conductive foam . Label any package that
contains static-sensitive assemblies or components.
3. Discharge the Static voltage from your body by
wearing a wrist strap while handling these com-

Graphic symbols and class designation letters are
based on ANSI Standard Y32.2-1975.
Logic symbology is based on ANSI Y32.14-1973 in
terms of positive logic. Logic symbols depict the logic
function performed and may differ from the manufacturer's data .
The overline on a signal name indicates that the signal
performs its intended function when it is in the low state.
Abbreviations are based on ANSI Y1 .1-1972 .
Other ANSI standards that are used in the preparation
of diagrams by Tektronix, Inc. are:
Y14 .15, 1966
Y14.2, 1973
Y10.5, 1968
Drafting Practices .
Line Conventions and Lettering.
Letter Symbols for Quantities Used in
Electrical Science and Electrical
Engineering.

New York, New York 10018
Component Values
Electrical components shown on the diagrams are in
the following units unless noted otherwise:
Capacitors = Values one or greater are i n picofarads (pF) .
Values less than one are in microfarads
(NF) .
Resistors = Ohms (S2) .
The information and special symbols below may appear in this manual.
Assembly Numbers and Grid Coordinates
Each assembly in the instrument is assigned an
assembly number (e .g ., A20) . The assembly number
appears on the circuit board outline on thediagram, in the
title for the circuit board component location illustration,
and in the lookup table for the schematic diagram and
corresponding component locator illustration . The
Replaceable Electrical Parts list is arranged by assemblies
in numerical sequence ; the components are listed by
component number '(see following illustration for
constructing a component number) .
The schematic diagram and circuit board component
location illustration have grids . A lookup table with the
grid coordinates is provided for ease of locating the
component . Onlythe components illustrated onthefacing
diagram are listed in the lookup table. When more than
one schematic diagram is used to illustrate the circuitry on
a circuit board, the circuit board illustration may only
appear opposite the first diagram on which it was illustrated ; the lookup table will list the diagram number of
other diagrams that the circuitry of the circuit board
appears on .

A 20 mA current-source approximation can be built
by inserting a 931 52,1% resistor and a 50 S2 potentiometer in series with a 20 V source . A 20 mA current source can also be obtained from another
PG 506 AMPL OUTPUT connector . Use the 2 V AMPLITUDE setting and adjust the VARIABLE (OUT)
control in a STD AMPL mode.

MANUAL CHANGE INFORMATION
At Tektronix, we continually strive to keep up with latest electronic developments
by adding circuit and component improvements to our instruments as soon as they
are developed and tested .
Sometimes, due to printing and shipping requirements, we can't get these
changes immediately into printed manuals. Hence, your manual may contain new
change information on following pages,
A single change may affect several sections . Since the change information sheets
are carried in the manual until all changes are permanently entered, some
duplication may occur. If no such change pages appear following this page, your
manual is correct as printed.
