OPERATING INSTRUCTIONS

INTRODUCTION

Description

The PG 506 Calibration Generator is designed to operate in a TM 500 Series Power Module. Theinstrument is a combination Amplitude Calibrator and Square Wave

Pulse Generator intended for cali bration and adj ustments of oscilloscope amplifier systems with a 500 or 1 MO input resistance.

A 5 mA Current Loop is provided, which supplies current (dc or 1 kHz) for calibration of current probes.

The Pulse Genercitor provides three square-wave out puts: variable High Amplitude pulses and simultaneous positive and negative-goi ng Fast Rise, vari able-amplit ude pulses. In the Pulse Generator mode, the Period is selectable from 1 J.lS 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 is also provided for triggering external equipment.

The Amplitude Calibrator function provides either a

+ dc 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 MO load and amplitude of 100 mV to

5 V across a 50 0 load are available . Output amplitudes are selected ina 1,2,5 sequence.

Because errors are often stated as a percentage, an internal digital differential voltmeter with front-panel light emitting 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 agree with the proper reference Ii ne, the output amplitude from the PG 506 Amplitude Calibrator can be varied until the proper alignment is obtai ned . I n this operating mode, the front-panel readout is a direct display of the oscilloscope deflection error.

Installation and Removal

~

Turn the power module off before inserting the plug in; otherwise, damage may occur to the plug-in circuitry. Because of the high current drawn by the

PG 506, it is also recommended that the power mOdule be turned off before removing the PG 506.

Refer to Fig . 2-1. Check to see that the plastic barriers on the interconnecting jack of the selected power module compartment match the cut-outs in the PG 506 circuit board rear edge connector.

AMPLITUDE CALIBRATOR MODE

Connections and Terminations

To use the PG 506 Amplitude Calibrator system, set the mode switch to the STD AM PL 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 500. characteristic impedance

(RG-58/U) with a maximum length of 42 inches (shorter cables can be used).

I

WARNING

I

Dangerous voltage may be present on the front panel BNC connector labeled AMPL OUTPUT

(HIGH or STD). Before installation, turn the control labled AMPLITUDE (VOLTS INTO 1 MO.) fully counterclockwise (ccw) and the control labeled

PULSE AMPLITUDE to MIN.

With a cable termination of 1 Mo. 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 500. 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 .

Align the upper and lower groove of the PG 506 chassis with the upper and lower guides of the selected compart ment. 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.

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 deflec tion accuracy be checked with a probe (properly compen sated) connected between the PG 506 and the os cilloscope input connector.

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.

For oscilloscope gain adjustments and checking of deflection accuracies, it is always best to set all os cilloscope 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 .

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.

Deflection Error Readout

When performing gain adjustments on oscilloscope or amplifier systems , it is mandatory that the DEFLECTION

ERROR readout be turned off in order to obtain calibrated 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.

2-4

@

Gain adjustments for oscilloscope amplifiers are usual ly 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 exactly five major divisions. At this poi nt , 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 .


2. Reduce capacitive and inductive loads to a minimum. Risetime degradation occurs with long cable lengths .

3. tained with 500 loads and loads must be capable of dissipating the power available at any output connector in any operating mode.

4.

Minimum risetime and pulse aberrations are ob

The external equipment is assumed to have no dc voltage across the load to which the PG 506 is connected.

If a dc voltage exists, the output amplitude from the

PG 506 will be in error by the amount of the dc offset. To prevent dc-offset errors, couple the PG 506 outputs through a dc blocking capacitor to the load. The time constant of the coupling capacitor and the total resistance in series must be long enough to maintain pulse flatness .

For some oscilloscopes the deflection factor may not be constant throughout the full vertical dimensions of the graticule, due to compression or expansion nonlinearities.

To check for this type of nonlinearity; center a two division 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 two division display to the bottom of the graticule and measure the deflection errors. These nonlinearities should be taken 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 grou nded and ter minates a precision voltage divider. The direction of the arrow is oriented for conventional current. To obtai n 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 dc or 1 kHz square-wave current, as selected by an internal switch.

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 frequency compensation 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 val ue 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.

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 500 coaxial cable , connectors, and terminations (where applicable). Make all connec tions as tight and short as possible.

Ag. 2-3. Output signals from the PG 506 Calibration Generator.

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 ac curacy should be verified before any risetime measure ments 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.

The graph for Fig. 2-4 can be used as a guideline for the following general conclusions.

1 . Oscilloscopes should have a vertical system risetime about one-seventh of the fastest signal applied to keep system errors to a minimum.

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.

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 OUTPUTS connector(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 high frequency 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 500 load. Larger amplitudes (greater than 1 V peak-to-peak) can be ob tained from these output connectors under unterminated conditions, but the risetime specification is no longer applicable.

3. The displayed risetime as observed on any os cilloscope 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 in a factor whose value lies between 0.329 and 0 .

350.

The followi ng steps describe the procedure to follow i n determining the risetime of a device under test.

1. Connect the appropriate output signal from the

PG 506 to the oscilloscope vertical input with a short 500 coaxial cable terminated into a 50 0 load.

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 . 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 .

For example; if the applied frequency, F" is 10 Hz and the amplitude values shown in Fig . 2-6 are used, the lower cut off frequency is calculated to be about 1.6 Hz.

Checking Amplifier Response

The square-wave output signals from the PG 506 can be used to check the response of active or passive sys tems. Because the characteristics of a pulse from the

PG 506 is known (see ELECTRICAL CHARACTERIS

TICS), distortion of the waveform beyond these limits is due to the device under test.

Figure 2-7 illustrates other waveform distortion effects that may be observed if amplifier circuits are not properly compensated for low frequencies.

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 rounding, the system is not correct ly compensated. Figure 2-5 shows typical waveforms illustrating correct and incorrect compensation ad justments. 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 poi nt (frequency where the equivalent si ne-wave amplitude is 30% down) .

THEORY OF OPERATION

Primary Power

0

The 120 V dc supply is the main power source for the

Standard Amplitude system. setting of the PULSE AMPLITUDE control and the exter nal load that terminates the PG 506 . With a 1 MO (unter mianted) load, the dc level will be about 3 .

5 V for the MIN position and about 20 V for the MAX position.

The + and 16.5 V dc 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 dc supply is the mai n power source for the High Ampl i tude 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 j unction 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 dc supplies are produced by conven tional full-wave bridge rectifier circuits that are driven by an inverter system that changes a dc voltage to ap proximately 25 kHz power in the primary and secondaries of T130. Each supply is switched on or off, dependent upon the operating modes

The 5 .

2 V dc supply is derived from a 11 .

5 V dc 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.

.

Voltage regulation for the Standard Amplitude and 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 i ts 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 seri es-pass transistor. Pi n 4 of U20 is the i nverti ng 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 Vacross the + and -16.5 V supplies is accomplished by adjusting

R30.

CR10 and CR11 , together with ClO , convert 25 V ac

(rms) from two transformer secondaries in the power module to about 35 V dc . VR 1 0 sets and regulates the base voltage of emitter-follower 0 15 to about 15 V , establ ishi ng a fixed 14 V supply for the 25 kHz free-running mul tivibrator (090-0100).

Current limiting for the 35 V dc input is controlled by the voltage drop across R22. If pin 2 of U20 goes about

0.6 V more positive than pin 3, pi n 10 goes negative to 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 tI-,e supply from over-voltage conditions if the potential difference across it exceeds

12 V .

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 085 and 0120 for the inverter system . The feedback connections from the collectors of

080 and 0125, through CR80 and CR125, ensures that both transistors are never on at the same time .

U20 sets its own reference voltage of about 7 Von pi n 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 Von p i n 2 of error amplifier U50.

The maximum voltage swing at the collectors of 080 and 0125 is about twice the dc level established at the junction of L35 and C36 in any operating mode. For the

High Amplitude mode , this dc level is dependent on the

Voltage regulation of the 5 .

2 V supply is accom plished by comparing the voltage leve l on pin 3 of U50 with the

3-1

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, returni ng the 5 .

2 V supply to its original level. essentially at the same potential (9 V) and pi n 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 500 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 operati ng potential at the base of 060 is about 9.2 V, with VR55 and CR55 not conducting. If the load current increases (due to lower load resistance), pi n 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 R234 sets a 9 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 U240, 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

0

The Standard Amplitude system consists of two sec tions, a high-voltage section and a 50 0 source section.

Output amplitudes of 100 V, 50 V and 20 V originate directly from a precision voltage divider composed of

R278, R277 and 0270

, R276, R275, and the 5 mA Current Loop output locks the base of about 100.7 V .

. For these three output amplitudes, the input to the 500 source section is disconnected and pin 2 of U375 is grounded through R380. With pi n 2 of U375 grounded, its to +16 V, disabling the

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

0255 are cut off (due to saturation of U255) and the quiescent level at the anodes of the matched diodes is

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 for the Digital Voltmeter circuit .

When R205 has been adjusted to produce 100.0 V across an external 1 MO load, pi ns 2 and 3 of U200 will be

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

R237 (or through C237) and applied to pin 2 of U240. 0245 operates as a level shifter and signal inversion through

0290 returns the 100 V bus to its calibrated level. CR290 and CR291 operate to limit turn-on surge current through

0290.

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 (cali brated 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, allowi ng the voltage swi ng 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 500 source section must drive either a 1 MO or

50 0 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 500 source section operates only when amplitude setti ngs of 10 V or lower are selected.

3-2 @

@

A nominal 14 V input to the 500 source section is derived from the precision divider at the junction of R275 and R276 and applied to pin 2 of U375 (R380 is dis connected from ground). This input voltage will always be a dc level proportional to the dc level established on the

100 V bus . U375 and 0365 operate as a tracking voltage source . If the input to U375 changes by 5 % , the collector voltage of 0365 changes by 5 % .

Theory of Operation-PG 506 (SN 8040000 & up) indicated deflection error of 7.3% HIGH, the variable 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.

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 sel ected output current levels through CR320 . Selected calibrated currents of 200 mA, 100 mA , or 40 mA split between three branches consisting of R316 , the symmetri cal 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 MO. With an external termi nation of 50 0 , 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 o dB reference , the total attenuation is 80 dB (20 dB per section) . The attenuator presents an output impedance of

50 0 at any voltage take-off poi nt.

Regulation for the constant-current supply is provided by the operational amplifier feedback connections from the current-setti ng resistors low level end through U330 to the base of 0326. 0320 is cut off for th e dc 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 dua l -slope integrating system . A change in input current to integrator U460 causes a ram p voltage to appear at pi n

The accumulated counts are d i splayed as being proportional to the value of the input voltage applied; a higher input voltage means a longer time t few cycles of dual-slope integration for the analog-to digital convertor system to settle down for a stable readout. o zero crossing, thus a higher count. It takes a

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 i n 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,theoutput of U470 is high and the counter is counting up to a count of 200 (00).

0475 is turned on and light-coupled through U480 to the base of 0480. The collector of 0480 is high, turning on

CR480 and HIGH indicator light 05480.

The system contai ns two reference current sources; a

+ 1, source from the collector of 0415 and a -I, source from the collector of 0400 . 0 nly 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 ram p that is negative, pi n 5 of U400B is set high and pi n 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 U400C is at a low level.

During the first ramp period, the output levels of U400A and U400B are high and both reference current sources a re cut off. See Fig . 3-1.

When the counter has reached a count of 200 (00) , a negative-goi ng Full Pulse appears on pi n 9 of U400C . 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 .

When the ramp crosses the 0 V level, a negative-going

Latch Pulse occuring on pin 7 of U470 is transmitted through C506 and CR502 to pin 13 of U400D . This Latch

Pulse switches pin 8 (common control line) of U400C to a low , locking out both reference current sources and turni ng off 0535 . A positive-goi ng Latch Pul s e appears at the collector of 0565 to store the cou nt in the counters for 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.

The base of Q580 begins a ramp runup toward the upper limit of the hysteresis window. When the ramp crosses the upper limit, Q580 is again turned off and Q575 turned on, reconnecting the timing resistors to the collector level 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 Q745 and Q758 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 Q745 be switched off for the output to swing from a negative potential to ground. Q760 serves as a 2 mA current shunt through disconnect diodes

CR766 and CR767. This circuit absorbs the leakage currents from Q745 and Q758 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 swi ng.

U610A and U610B 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 U667 . Pin 12 of U61 0 is a Q term i nal and the 1 kHz output signal is used to drive the diode section of U255 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 in a dc mode when pi n

2 is grounded by the closure of S660. For the High

Amplitude mode, pin 2 is grounded through CR661; for the

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 transistors Q745 and Q758 are connected in cascode and the voltage transitions at the base of Q745 determines the output current swi ng. A negative transition at the base of Q745 requires a negative-goi ng transiti on at the base of Q715 to saturate Q730 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 Q725, Q740, and Q790 translate the dc (and signal) levels from ground to a negative supply for the output stages and amplitude control ci rcuitry. Q790 is a 4 mA current source that floats the amplitude control circuitry at about 6 V more positive than the variable supply voltage level. The input signals to U61 OB (as selected by the PERIOD control) are obtained from the frequency dividers (pin 11) ordirectly from the2 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 inverted polarity if the other input termi nal 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 S 180A-5B. This acti on sets pi n 9 of U 61 OB to a logical zero (low) and pin 8 to a logical one (high).

R736 in the emitter of Q736, along with R746 in the emitter of Q745 , are chosen so that the current into these nodes is a function of the actual supply Voltage. The actual current that enters Q745 is controlled by the base voltage and the voltage drop across R745 . The emitter of Q736 is a low-impedance driving point that controls the output current limits. Q736 also temperature-compensates the base junction of Q745. The base of Q736 (and the collector of Q782) is considered to be a zero temperature coeffi cient voltage point.

The closure of S 180A-7B locks out drive signals to the

High Amplitude circuitry when the instrument is in a Fast

The PULSE AMPLITUDE control is R785A, located in the base circuit of Q784. This control obtains its reference voltage from across VR790. Q780 and Q784 form a differential circuit with Q780 connected as a diode for

3-5

Theory of Operation-PG 506 (SN 8040000 & up) temperature compensation. 0736 is driven by 0782, which adds additional gain to set the base of 0780 equal to 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 n 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 0780 and 0782, thereby improving the amplitude linearity . in series with the emitters of 0935 and 0995. A negative transition occurs at J950 when 0935 is turned off and a positive transition occurs at J1010 when 0995 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 n.

The sensing point to regulate anyone level of the variable supply is at the collector of 0790. 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.

The actual voltage of the vari able supply is made a function of the negative peak levels of the output signal.

The negative peaks are sampled through CR800 and emitter-follower 0800 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 dc supply for the inverter system in 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 0745 is connected through VR790 to pin 2 of U840; the drain of

0758 is connected through 0800 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 t he output transistor network is essentially equal to the drop across VR790 plus about 2 to 7 V across other com ponents in the feedback loop .

Fast Rise

0

The Fast Rise circuit produces two output signals that occur simultaneously . 0935 and 0995 operate as non saturated 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 0935 and 0995 are cut off.

Simultaneous amplitude control of the output signals is accomplished by diverting current from the emitters of

0935 and 0995 through the series path of 01036 and

01045 . The voltage drop across R 1 040 is controlled by the adjustable voltage level at the emitter of 01030, a low impedance source for the base of 01036.01020 operates as a current switch to set the collector of 01030 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.

When the Fast Rise mode is switched off, the

+ and

-16.5 V supplies are switched off .

The collectors of 01020 and 01030 drop to about zero, driving the base of 01036 negative. This action completely cuts off the leakage currents that might have existed in the collectors of 0935,

01036, 0995, and 01045 if the collector of 01030 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 .

0860 and 0862 operate as a Schmitt tri gger for the Fast

Rise circuit, with VR866 providing positive feedback and

0850 servi ng as a constant-current source . A positive goi ng pulse at the base of 0860 results ina negative-goi ng pulse at the collector of 0880 and a positive-going pulse at the collector of 0890, 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 (0900-0910 and 0960

0970). For a positive-going input to the base of 0960 , the emitter of 0935 is driven negative by the saturation of

0920 and the emitter of 0995 is driven positive by the saturation of 0980 .

In order to produce 1 V across a 25 n load (50 n termination in parallel with either R950 or R1010) it requires 40 mAo This current isavailablethrough res i stors

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 c i rcuits of

20 mA Current Source

A 20 mA current source is needed for the adj ustment of the PG 506. Another PG 506, if available, can be used for this purpose by using the AMPL OUTPUT conneCtor, setting the AMPLITUDE control to 2 V, and adjusting the

VARIABLE (OUT) control in STD AMPL mode.

However, you should be able to obtain many of the standard electronic components from a local commercial source. Before you purchase or order a part from a source other than Tektronix, Inc., please check the Replaceable

Electrical Parts list for the proper value, rating, tolerance, and descri ption .

Ordering Parts

When ordering parts form Tektronix, I nc., it is impor tant that all of the following information be included to ensure receivi ng the proper parts.

If another PG 506 is not available a 20 mA current source approximation can be constructed by inserting a

931 0, 1 % resistor and a 50 0 potenti om eter in series with a 20 V supply.

Most electrical and mechanical parts can be obtained through your local Tektronix field office or representative.

1 . Instrument type (including modification or option numbers).

2 . Instrument serial num ber.

3. A description of the part (if electrical , include circuit number).

4. Tektronix part number.

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 perfor ming 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-i ns through the interface .

Fig. 5-1 shows the pins and their assignments.

~

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 bed

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 other

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

PG 506 into a a slot with rear interface wiring for any other signal source family connection without mak ing the same compatibility check.

Static-Sensitive Components

~

Static discharge can damage any semiconductor component in this instrument.

Maintenance-PG 506 (SN B040000 & up) 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.

6 . Pick up components by the body, never by the leads.

7. Do not slide the com ponents over any surface.

8. Avoid handling components in areas that have a floor or work-surface coveri ng capable of generating a static charge.

9. Use a soldering iron that is connected to earth ground .

10. Use only special antistatic suction type or wick type desoldering tools.

NOTE

Each of the MSD and LSD outputs is only capable of driving one TTL load . The active level of each output is high.

For the Hi-Lo Output, output is low when the HIGH display light on the front panel is on.

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 k8 to 30 k8 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 com ponents.

3. Discharge the static voltage from your body by wearing a wrist strap while handling these com

DIAGRAMS AND CIRCUIT BOARD ILLUSTRATIONS

Symbols

r

Graphic symbols and class designation letters are based on ANSI Standard Y32 .2

-197S. r 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 manufac turer'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 Y 1 .

1-1972 .

Other ANSI standards that are used in the preparation of diagrams by Tektronix, Inc. are:

Y14 .

1S, 1966 Drafting Practices .

Y14 .

2,1973 Line Conventions and Lettering .

Y1O.S, 1968 Letter Symbols for Quantities Used in

Electrical Science and Electr i cal

Engineering.

American National Standard Institute

1430 Broadway

New York, New York 10018

Component Values

Electrical components shown on the diagrams are in the following units unless noted othe r wise:

Capacitors = Values one or greater are i n picofarads (pF) .

Values less than one are in microfarads

Resistors

(pF).

=

Ohms (0).

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 the diagram, in the title for the circuit board component location illustration , and in the lookup table for the schematic diagram and corresponding component locator ill ustration. The

Replaceable Electrical Parts list is arranged by assemblies in numerical sequence ; the components are listed by component number ·(see following illustration for constructi ng a com ponent num ber).

The schematic diagram and circuit board component location illustration have grids . A lookup table with the grid coordi nates is provided for ease of locating the com ponent. ani y the com ponents ill ustrated on the facing diagram are listed in the lookup table . When more than one schem atic diagram is used to ill ustrate the circuitry on a circuit board, the circuit board illustration may only appear opposite the first diagram on which it was il lustrated; the lookup table will list the diagram number of other diagrams that the circuitry of the circuit board appears on .
