REV B MAR 1980

OPERATING INSTRUCTIONS

Section 1 -SG 504

De scription

The SG 504 provides a constant-am plitude sine wave over a frequency range from 245 MHz to 1 050 MHz.

Amplitude-reference sine waves of .05 M Hz or 6.0 MHz

(selected by internal switch) are provided. The output head has an output impedance of 50 ohms. The peak-to­ peak voltage from the output head is adj usted by a calibrated five-turn potentiometer. The SG 504 Leveled

Sine Wave Generator is desig ned for use in the TM 500 series power modules.

Align the SG 504 chassis with the upper and lower gui des of the selected com partment. Push the module in and press firmly to seat the circuit board in the inter­ connecting jack.

To rem ove the SG 504, pull on the release latch located in the l ower left corner, until the interconnecting jack disengages and the SG 504 wi ll slide out.

The front-panel FREQUENCY MONITOR OUT con­ nector provides at least a 0.3 V peak-to-peak signal at the selected output frequency (245 to 1 050 MHz) for monitor­ ing or external triggering. There is also a provision for frequency modulating the 245 to 1 050 MHz output signal.

When lit, the U N LEVELED light indicates a mismatched load or when the OUTPUT AMPLI TUDE front-panel control should be turned counterclockwise. When the output head is disconnected from the front panel, the

UN LEVELED light is also i l l uminated.

Controls and Conne ctors

Refer to Fig. 1 -2. Even though the SG 504 is fully cal ibrated and ready to use, the functions and actions of the controls and connectors should be reviewed before attem pting to use the instrument. Pull the Power switch on the power module to apply power to the SG 504. The

POWER indicator light indicates when power is applied to the SG 504.

Except for very early models of the SG 504, the front panel bears the inscri ption:

A

This symbol is to direct the operator to read the operating instructions to avoid a hazardous situation.

Rear interface connections are provided for the FM

I N PUT, FREQUENCY MONI TOR OUT, and amplitude control . If the rear interface is used, these front panel features must be disconnected. They cannot both be used at once. For further information about the interface assignments, see Section 4, Maintenance and I nterfacing

I nformation, of this manual. When using the crank on the FREQUENCY MHz dial, observe the stop notations on the dial tape. To prevent possible internal damage or miscalibration, do not force the knob hard against the mechanical stops.

Installation and Re moval

�

Turn the power module off before inserting the plug­ in and before connecting the output head to the

SG 504 front-pane/ connectors; otherwise, damage may occur to the plug-in circuitry. It is also recommended that the power module be turned off before removing the SG 504. Refer to Fig. 1 - 1 . If it becomes necessary to install the output head cables after the instrument has been turned on, make sure the four-pin connector is inserted first. Then, con­ nect the bnc coaxial connector. Check to see that the plastic barriers on the interconnecting jack of the selected power module compartment match the cut­ outs in the SG 504 circuit board edge connector.

OPERATING CONSI DERAT IONS

Overhe ating

The SG 504 is designed to operate at an ambient tem perature from 0°c to +50°C. However. when operating several power supplies in a multi-pl ug-in power module, especially at high line voltages. or when operating close to other heat-prod ucing equipment, inter­ nal tem perature may exceed safe l i mits and actuate a thermal cutout in the power module. Refer to the power module instruction manual for m ore complete informa­ tion.

�

If the SG 504 is left in a power on state for long periods of time, turn the O U TP U T AMPLI TUDE control to less than 3 volts output amplitude. In all cases, reduce the output amplitude to less than 3 volts when the output head is unterminated. This procedure prolongs instrument life.

Con nect the properly terminated output head to the device under test. If the front-panel UNLEVELED light comes on, turn the O U T P UT AMPLITUDE control counterclockwise until the light goes out. Output heads may be interchanged and will perform within specifications; however, optimum performance is ob­ tained by not changing heads after calibration.

Output Loading

The SG 504 is designed to operate into a 50-ohm impedance. If the load is a much greater impedance than

50-ohm, connect a feed-through termination to the output head and then make connection to the load. Refer to Fig.

1 -3(8) for reference.

It is important to minimize adapter and transmission line discontinuities and reflections. Adding coaxial cable between the output head and the load im pairs the constant am plitude function, si nce transmission line insertion losses vary with freq uency.

NO TE

When lit, the UNLEVELED light on the front panel indicates a mismatched load or when the OUTPUT

AMPLITUDE control should be turned coun­ terclockwise. When the output head is disconnected from the front panel, the UNLEVELED light is also illuminated.

If there is a de voltage across the load, use a de blocking capacitor between the output head and the load. A de blocki ng capacitor, listed in the Accessories section of this manual, can be used for frequencies from 6 to

1050 MHz.

I f sig nal amplitudes less than the minim um (0.5 V p-p) are desired, use appropriate attenuators connected between the output head and the device under test.

NOTE

Tektronix attenuators with -02 suffix are recommended. Other attenuators may be used; however, measurement accuracy may be com­ promised.

Operating Instructions-SQ 504 control for the desired ampl itude. Now push either the

H I G H or LOW RANGE pushbuttons and adjust the

COARSE frequency control until the amplitude equals

0.707 times the reference deflection. The frequency is now the 3 dB down frequency of the device under test. If band pass measurements are made at different am bient temperatures, recheck the reference amplitude.

When operating the SG 504, al ways consider the total load impedance and its effect on the output amplitude.

The input capacitance of the equipment under test will affect the bandwidth. The equivalent circuit shown in Fig.

1-3(C) is useful in estimating the amplitude changes caused by capacitive loads. Note that as system input capacitance increases, bandwi dth decreases.

When frequency accuracy better than 2% is required, con nect a frequency counter to the FREQUENCY

MONITO R OUT connector. The signal available at this connector is the same frequency as the output and its use does not l oad or affect the amplitude of the signal from the output head. However. the output head must remain connected to the load for this frequency measurement to be accurate.

WARNING

I

When the SG 504 is energized, hazardous voltages exist at some of the circuit board terminals. Before changing the reference frequency with the internal slide switch, be sure to disconnect the power to the

SG 504. Refer to Fig. 3-1 tor internal switch location.

Bandp ass Me asu re me nt s

To measure the bandpass of an oscilloscope or other device, connect the output head to the device. Select the reference frequency (0.05 MHz or 6.0 MHz) , using the internal slide switch on the main board. Push the front panel REF pushbutton. Adjust the OUTPUT AMPLI TUDE

Fre que ncy Modu late d Output

To frequency modulate the output, connect the modulating sig nal to the FM I N PUT con nector on the front panel. Set the front panel FREQUENCY MHz F I NE control to zero. Set the OUTPUT AMPLITUDE control below approximately 3 V peak to peak. This is desirable because at hig her levels the frequency may shift slightly with changes in the AMPLIT U DE control settings. The FM

I N PUT and the FREQ UENCY M Hz F I NE control drive the same summing point. Consequently, the maxim um fre­ quency deviation +and at a particular frequency, can be demonstrated by turning the F I NE control fully cw and then fully ccw and noting the f requency change. The FINE control range is equivalent to approximately a ±9 V change at the FM INPUT. Do not use more than ±9 V at the

FM I N PUT. Linear deviation is assu red below ±1 V i n put.

Regu lation) a. Set the SG 504 controls as follows: REF pushbutton in, OUTPUT AMPLITUDE control to 0.5, FREQUENCY

MHz setting to 245, and FI N E control to O (centered) .

NOTE

This procedure uses the harmonics of the 50 MHz cal out signal to check the accuracy of the frequency at six check points. Essentially the same procedure can be followed to check the accuracy of any other frequency on the low or high range, providing that the frequency checked is a harmonic of the 50 MHz cal out signal from the spectrum analyzer. Frequen­ cies other than the six calibration check points must be within the 2% specifications. b. Connect a 2.4 megohm, 5 % resistor across the digital voltmeter fl oating input terminals. Connect t he

SG 504 Output Head via bnc female-to-GR adapter to t he input of the peak-to-peak detector. Use two 50 O cables and two dual banana to bnc adapters to connect the output of the peak-to-peak detector to the floating input terminals on the digital voltmeter; maintain correct polari­ ty, HI to + and LO to -. Set the digital voltmeter to the 20 volts de range. g. Adj ust the spectrum analyzer Frequency Coarse control to horizontally center the 250 MHz signal on the graticule. Use Table 2-5 as reference for verification otthe six frequency check points. c. Slowly adjust the SG 504 OUTPUT AM PLITUDE control until the digital voltmeter reading indicates ±.000.

Output amplitude from the SG 504 should be about 1 .2 volts; this establishes a 0.0% reference setting at

0.05 M Hz. d. Set the SG 504 internal slide switch, S1 90, to the

6 MHz position. See Fig. 3-1 for switch location.

NOTE

The two markers may coincide during the low frequency range setting. If so, verify the presence of the SG 504 frequency signal by slightly adjusting the SG 504 COARSE control.

NOTE

Do not disturb the approximate 1.2 volt setting of the

SG 504 OUTPUT AMPLITUDE control, as set in part c of this step; otherwise, an incorrect deviation reading will occur.

Check-the flatness deviation from the 0.0% reference setting; the voltage reading of the digital voltmeter should not be greater than 0.5% ( .001 volt output from the peak-to-peak detector is equivalent to 0. 1 %). f. Push in the SG 504 LOW RANGE push button. Note and record the reading of the digital voltmeter for the fl atness deviation at 245 MHz; for example, -0.2%. The total percentage deviation calculation must incl ude the digital voltmeter reading and the calibration factor of the peak-to-peak detector. For example, a reading of -.002 volt on the digital voltmeter is equivalent to "-0.2% deviation. Applying a correction factor of -0.3% algebraically to the -0.2% val ue results in a total percen­ tage deviation of -0.5%. Record the actual algebraic sum at this point; it will be used later in the procedure.

ADJUSTMENT

I ntroduction

This adjustment procedure is to be used to restore the

SG 504 to original performance specifications. Adj ust­ ment need not be performed unless the i nstrument fails to meet the Performance Requi rements of the Electrical

Characteristics listed in the Specification section, or the

Performance Check cannot be completed satisfactorily.

Com pletion of all adjustment steps in this procedure ensures that the i nstrument will meet the performance requi rements listed in Section 2 Specification and Perfor­ mance Check. However, to fully ensure satisfactory performance, it is recommended that the Performance

Check be performed after any adjustment is made.

WARNING

I

The ceramic portions of 070 and Q 1 20 contain

BERYLLIUM OXIDE as a major ingredient.

Beryllium Oxide heat sinks are safe under most conditions. The only hazard is that a toxic effect may occur if Beryllium Oxide fumes or fine particles are inhaled. Grinding, crushing, or heating above

1800° F can produce fumes or fine particles. A void such action and subsequent inhalation to assure the absence of any hazard. No hazard is present in normal instrument operation or maintenance.

Disposal of transistors containing Beryllium Oxide should be handled in such a manner to ensure that no future hazard will exist.

Due to high-freq uency loading effects when troubleshooting the circuits of 070 or 0 1 20 with the power on, do not place a probe directly to the base of either transistor. If it becomes necessary to measure the base­ emitter (bias) voltage of 070 or 0 1 20, place the proper probe at the junction of L52-R54 or at the j u nction of L 1 02-

R 1 04 and the other probe on the emitter. The normal operating bias for either transistor is between 0.7 V and

0.85 V at the low end of the LOW or H I G H RAN G E of the

To replace 070 or 0 1 20, first remove the four connec­ tors to the rt board. Remove the cover of the rt board by rem ovi ng the eight screws holding it i n pl ace. Next, remove the rt board by removing the four screws holding it to the mai n circuit board and lift the rt board out. Remove the nut holding the defective transistor to the heat si n k.

U nsol der the l eads of the defective transistor and remove the transistor. Pay particu lar attention to the spring washer between the heat sink and the rt board; the spring washer must be i n place when the transistor is re-i nstal led.

The spri ng washer should stay in place. If it becomes dislocated do not loosen the nuts holding the heat sink to the board; use another means to center the spri ng washer before replaci ng 070 or 0 1 20. Use a solder wick i nstead of a suction device to unsol der the transistor l eads. connections to the Low and High Range sections

(Osci l l ator Supply, Oscillator Varactor). Remove the front panel COARSE knob plus the n ut and washer holding the bushing to the front panel . Rem ove the five screws holding the oscil l ator sections to the main circuit board and slide both sections backwards until t he osci l l ator shaft clears the front panel.

To remove the dial tape from its mounti ng, remove the two retai n i ng rings, the two flat washers, and the tape retai ning plate. Careful l y remove the d ial tape with its rollers. Do not bend or distort the Teflon washers u nder the tape rollers.

To re-i nstall 070 or 01 20, trim the leads to their proper l engths and i nsert the transistor through the holes in the rt board, the spring washer, and the heat si nk. Be certai n that the collector lead is properly oriented and maintains its orientation while tightening the n ut on the t ransistor stud.

Be certain to replace the flat washer between the stud n ut and the heat sink. Torque the n ut holding the transistor to the heat si nk to six i nch-pounds. Solder the transistor leads in place.

I n order to avoid grounding the collector tabs of 0520 or 0560, do not reapply power to the i nstrument u ntil the

High Range coaxial cable i s reconnected.

A new dial tape comes with one roller ( similar to a typewriter ri bbon). To repl ace a new d i al tape, start the new tape on the roller that was i n the original assembly and unroll the tape until the 450 MHz cali bration mark is centered between the two rol lers. Slightly turn the os­ cillator shaft so that the four set screws attaching the gear to the osci l l ator shaft are accessi ble through the lower left quadrant of the assembly. Place the dial tape rollers over the support posts so that the teeth i n the tape are engaged with the gear. Be certai n that the two Teflon washers are between the rollers and the mounting; a bent or distorted

Teflon washer may bind the tape. Replace the tape retai ning plate, flat washers, and retai ning rings i n that order. Apply Lubriplate to the total length of the top edge of the new tape.

Replacement of 0520 or 0560

If it becomes necessary to replace either of these transistors, note the orientation of the bevel on the transi stor case. The emitter terminal of 0520 and 0560 is on the beveled side of the case. Proper orientation of 0520 and 0560 is shown on the Parts Location Grid and by a dot on the circuit board which i ndicates the emitter connec­ tion. The metal tabs are connected to the collector termi nal.

After replaci ng the dial tape, the osci llator sections, the control knob, and the rt board refer to the appropriate steps in the Adjustments Procedure for detai led i nforma­ tion that describes how to cali brate the oscillator sections to the tape dial readi ngs.

Checking the Output Head

If the SG 504 is not operating properly, and cali brati on does not correct the problem, then an Out put Head malfu nction is the li kely cause and should be checked for a possible defect.

Dial Tape Mechanism

NO TE

In order to facilitate re-calibration of the oscillator sections when it becomes necessary to repair the dial tape mechanism, it is suggested that the os­ cillator be tuned for a 450 MHz output signal before removing the oscillator sections.

The oscillator sections must be removed to repair or replace the dial tape or its associated mechanism. To remove the oscil lator sections, fi rst remove the rt board accordi ng to the instructi ons under the headi ng Servicing and Replacing Output Buffer Ampl ifi ers. Unsol der the four

Turn off the power and chec k t hat the five de control connections between the harmonica con nector ( P265) located on the main circuit board, and the front-panel connector (J 260) are properly made. I nspect the pins i n

J260 and P260 t o verify that n o pin i s bent o r broken. Also, check the i nternal wiring on P260 to verify that wi res are not broken, frayed, or shorted together.

Perform the fol lowi ng check steps to determine if possi ble defects exist i n the Output Head. I f any of t he readi ngs are si gnificantly different than those listed i n the check steps, a defect in the Output Head can be assumed.

If that is determ i ned, return it to the nearest Tekt ronix

Field Service Center, as it is not customer repairable.

Before using an ohmmeter, determine the polarity of the test leads. Identify or label the + and voltage leads. This is especially important when testing circuits that contain diodes. When testing diodes with an ohmmeter do not use an ohmmeter scale where the voltage between the test leads exceeds the diode break-down rating or causes excessive forward current to flow through the diode(s). For the

SG 504 Output Head the open-circuit voltage between the ohmmeter test leads should not exceed

26 volts and the maximum short-circuit current should not exceed 20 mA. A TEKTRONIX DM 501 or

DM 502 meets these requirements.

This section of the man ual contains a descri ption of the circuitry used in the SG 504 Leveled Si ne Wave Generator.

I ndividual descriptions are separated i nto the following parts: Am plitude Reference Osci llator and Buffer

The output amplitude of the reference osci llator is controlled by varying the emitter voltage suppl i ed to 0 1 90 from the osci l l ator power su pply. The oscillator power suppl y is driven by the level ing amplifier ( U295) . The output from the reference oscillator is applied through L 1 78 to the output head.

Frequency Modulating Circuitry

<!)

This ci rcu itry consists of operational amplifier U25 which is d riven by two basic i n puts: the F I N E control, R 1 5, or an exter nally appl ied signal to the FM I N PUT on the front panel. The output voltage from the operational amplifier varies t he frequency of the hig h and low varactor control led oscillators over a narrow range. If the F I N E control is moved i n t h e c w direction, pin 2 o f U 25 moves sl ightly positive with respect to pin 3. This causes pin 6 to go negative. This i ncreases the amount of back bias on the varactor diodes, red ucing their capacitance. This action raises the output frequency. The opposite is true when the

FI N E control is moved in the ccw di rection.

General

The SG 504 consists of a .05 MHz or 6 MHz Hartley am plitude reference osci l l ator, two transistorized cavity osci l l ators, and the necessary buffer ampl ifiers. Constant am plitude o utput from the generator is controlled by a vari able power supply and low and high band P I N di ode attenuators. The l evel ing amplifier drives both the os­ cillator supply and PI N diode current shapi ng amplifiers, and is driven by the peak-to-peak detector i n t he output head. Also i ncluded are the FM circuitry and the necessary power suppl ies.

Amplitude Reference Oscillator and Buffer Amplifier

0

The reference output frequency of .05 MHz or 6 MHz is generated by 0 1 90 operating as a Hartley osci l l ator. The tank circuit for the .05 MHz reference signal is com posed of T205, C205 and C207, and for the 6 MHz reference signal, T200 and C200. The tan k circuits are switched by an i nternal slide switch ( S 1 90) for t he refererence frequen­ cy desired. Oscil l ator feedback is taken from the fi rst tap on either coi l (Pin 3 on T200 or Pin 2 on T205) through

R 1 96 and C 1 95. The signal to buffer am pl ifier transi stor

0220 is also taken from this fi rst tap through C220. Diodes

VR230, CR230, CR232, and VR232 serve as output voltage limit i ng diodes. Transistor 021 5 is a c urrent switch for t he output buffer ampl ifier (0220). When the R EF button on the front panel is pushed, a negative voltage from the oscillator power su pply is applied to the emitter of 0 1 90.

This voltage energizes the osci llator. The oscil l ator ob­ tains coll ector voltage from the +s V supply through the emitter-base ju nction of 0215 and R21 2. This action causes 0215 to cond uct. suppl yi ng cu rrent to the buffer am plifier transistor (0220). When the reference osci l l ator is i n operative, no current flows through the base-em itter

The mod ulating si gnal is also con nected to pin 2 of operational amplifier U25 through R 1 2. When the modulati ng signal goes i n the positive direction, the output of the operati onal amplifier goes negative, i n­ creasi ng the back bias on the varactor diodes. The output frequency i ncreases in proportion to the amplitude of the modulating signal. The output voltage at pin 6 of U25 varies from about -3 V to about -21 V. When the F I N E control is centered, the output voltage a t pin 6 i s about

- 1 2 V. Su pply voltage to U25 is reg ulated by VR25. Diodes

CR30 and VR30 provide protection for excessive negative voltage at the mod ulating i n put. Protection for excessive positive voltage at the modulating i nput is accom plished by limiting the negative supply voltage for U25 to about

25 v.

Low Band Oscillator and Buffer

<!)

When the LOW button is pressed, voltage is appl i ed from the osci llator voltage supply to the low band transistori zed cavity oscillator. The output from the os­ ci l l ator is applied (through C97 and C99 and thei r associated components serving as a match i ng network) to the base of low band buffer transistor 01 20. As the i n put im pedance of the buffer transistor is less than 50

0, a matching network is requi red to match the output of the cavity (which is about 50 0) to the buffer transistor. The

- 1 2 V bias su pply is isolated from the output sig nal through L 1 02, C1 02, and C 1 04. The emitter i s ac grou nded vi a C 1 1 0, C1 1 2, C1 1 4, and C1 1 6 and i solated via L 1 08 from http./

R EV A, AUG 1 978

Circuit Descri ption-SG 504 the emitter power supply. The output from the buffer i s taken from t h e collector o f 01 20, then fed throug h a l ow­ pass fi lter to the 50

0

PIN diode attenuator. (L 1 25, L 1 26, and L 1 28, along with their associated capacitors, form the l ow pass filter and matching network.) Coll ector de current for 0 1 20 flows to ground through L 1 30, acting as a rf choke. The frequency monitor output is taken from the

PIN diode attenuator i nput.

If the output signal i ncreases due to decreased l oading, pin 2 of U295 goes positive, upsetti ng the bal ance in the feedback l oop. Pi n 6 of U 295 goes negative, causi ng pi n 3 of U335A and pi n 6 of U335B to also go negative. Pi n 1 of

U335A goes negative, i ncreasi ng current flow in tran­ sistors 0380, 0395, and 0405. This acti on i n creases current flow through 041 0 and 041 5; conseq uently the shunt PIN diodes. I ncreased current through the sh u nt

PIN diodes reduces the output signal ampl itude and restores signal balance. Pin 7 of U335B moves in the positive di rection, red uci ng current flow i n 0345 and

0355. This action cuts back on cu rrent flow i n 0365 and

0370, therefore decreasing current in the series P I N diodes. I n summary, the output signal i s reduced.

The signal now flows through low band series P I N diode C R 1 30. A s described l ater under t he heading P I N diode current shaper, i ncreasing the de current flow through C R 1 30 reduces the attenuation through the diode. Rf chokes L 1 35 an d L 1 30 provide the de path. High band series PIN d iode CR80 (for the non-operating oscillator) has no de current f l owi ng, therefore isolati ng that buffer. The output sig nal flows i n a 50 n environment, past shunt PIN diodes C R 1 55, C R 1 58, and C R 1 60 to the output head. Shunt Pl N diode control voltage is appl ied to the three shunt diodes via L 1 50. Capacitors C 1 47 and

C 1 50 isolate the shunt diode control voltage from the output and the series diodes. Low band capacitor C 1 25 allows proper adjustment of the oscillator at the 550 MHz frequency point.

High Band Oscillator and Buffer

�

This circuitry is similar to the Low Band Oscillator and

Buffer. The oscillator is also a transistorized cavity with an output im pedance of approxim ately 50 n. The output signal from the cavity flows through a network that matches the lower im pedance at the in put of 070, the buffer amplifier. This network is com posed of C47, C49,

C50, L45, L48, and R45. Toroi d L52 serves to isolate the transistor bias supply from the signal; L58 isolates the emitter current supply from any signal appeari ng on the emitter of the buffer transistor. The various capacitors con nected from the emitter of 070 to ground ensure that the emitter of 070 remains at ac ground for all frequencies i nvolved. Output from 070 is taken from the coll ector and fed through a low pass filter to high band series P I N diode

CR80. This network also matches the output impedance of

070 to the 50 0 P I N diode attenuator i nput. The high band signal is fed to the output head through CR80 and past the shunt PIN diodes. High band capacitor C75 allows proper adjustment of the oscillator at the 1 050 MHz frequency poi nt.

Shunt-Series PIN Diode Current Shapers

4>

The output from leveli ng amplifier U295 pi n 6 is appl ied to the + i n put (pin 3) of U335A, and the i nput (pin 6) of

U335B. O perational amplifier U335A drives the current­ shaping transistors for the shunt Pl N diodes; U335B drives the seri es PIN diode current-shapi ng transistors. PIN d i odes CR80 and C R 1 30 are i n series with the output signal, while PIN diodes C R 1 55, C R 1 58, and C R 1 60 sh unt the output signal to ground.

The current shapers are desig ned so the i n put im­ pedance of the series and shunt com bination ap­ proximates 50

0

for all attenuation ratios. Resistors R41 8,

R420, and R422 set the bias current to the series PIN diodes i n the attenuators, so that the attenuator i n put im pedance remains approximately 50 n at maxim um attenuation.

Leveling Output Head and Amplifier

4>

Operati onal amplifier U295 serves as the l evel i ng am plifier. The voltage at the + terminal, pin 3 (about

-0.8 V) is set by current flowing from the - 1 8 V supply through R288 and a diode- resistor network in the output head to ground. This output head di ode-resistor ci rcuit provides tem perature compensation. The voltage difference between the peak-to-peak detector circuit i n the head and the voltage level set b y R275 (the O UTPUT

AM PLITU D E VOL TS control), drives pin 2 of U295 with respect to pin 3. The OUTPUT AM PLITU D E VOL TS control sets a de reference voltage, while the actual output signal amplitude sets the comparison voltage. U nder l eveled operating conditions, the voltage at pins 2 and 3 of

U295 match. When the OUTPUT AMPLITUDE VOL TS control is moved to i ncrease the output amplitude, pin 2 of

U295 goes negative, causing pin 6 to move i n the positive direction. This action i ncreases output from the oscillator or reduces Pl N diode attenuation u ntil the de voltage from the peak-to-peak detector agai n establishes equili brium at the i nput of U295. The l eveled operating range of voltage on pi n 6 of U295 varies from about - 1 3 V to 0 V.

Unleveled Lamp Drivers

04>

When pi n 6 goes more positive than about 0.6 V, steering diode CR31 8 turns 031 5 on and ill umi nates the

UNLEVELED li ght. This i nd icates that the maximum avail able output signal is passi ng through the buffer amplifier. If pin 6 goes more negative than - 1 5 V, 0305 turns off and CR310 conducts, turning 031 5 on il­ l umi nating the U N LEVELED l am p. This is caused by disconnecting the output head control cable, which results i n pin 3 of U295 goi ng more negative than pin 2.

This drives pin 6 to its negative l i mit, which reduces the osci l l ator output and increases PIN diode atten u ation.

5-2 http./ tmanoman sqh II.com

REV 8, AUG 1 978

A second protection circuit prevents excessive signal voltages from developing if the signal cable to the output head is disconnected while the control cable is connected.

Wit h the signal cable connected, there is a 1 .5 kO resistance i n the output head to ground that holds 0 1 70 off. With the signal cable disconnected, the base of 0 1 70 moves toward - 1 2 V. Si nce 0 1 70 is sat urated, its coll ector now rests at grou nd. This action moves p i n 2 of U295 i n the positive di rection, i ncreasing attenuation in the PIN diode attenuator or reducing oscillator output. This positive goi ng voltage at pin 2 also turns 0305 off, causi ng C R31 0 to conduct. This action turns 031 5 on and i l l umi nates the

UN LEVELED lamp.

-18 V Supply

�

The - 1 8 V supply i s obtained from t he -33.5 V de supply which i s in turn suppl ied by the power mod ule. The

-33.5 V passes current through the series-pass pnp transistor l ocated in the mainframe. This transistor is controlled by U580, an i ntegrated circuit preci si on voltage regulator. Adjustment of R590 sets the 1 8 V output level t hrough pin 9 of U580. Pin 9 sets the base current for the series-pass transistor. If the total current through R604 and R605 exceeds approximately 400 mA, 0600 comes i nto conduction. This action reduces the base current i n the series-pass transistor, l i miting current t o the load.

A - 1 2.4 V base bias voltage for t he l ow and high buffers is obtained by R525 and R526, and the emitter fol lower action of 0530 connected between the - 1 8 V supply and ground.

Buffer Current Supply

�

Emitter current for the high buffer comes from the

1 8 V supply. Operational amplifier U510A, adj usted by

R502, sets the voltage across R518 to determi ne this current. Emitter current for the low buffer also comes from the - 1 8 V supply. Operational am plifier U51 0B, adj usted by R542, sets the voltage across R558. Proper adjustment here reduces the harmonic content of the output signal and allows for the maximum leveled output signal.

Over-Voltage Protection

�

An over-voltage protection circuit is provided for both the 1 8 V supply and the - 1 4/-23 V oscil lator supply through the use of 0650, 0655, and 0660. If the - 1 8 V supply moves to an approximate -23 V, 0655 turns on, triggering 0660 i nto conduction. This action shorts the

- 1 8 V supply to ground. If the - 1 4/-23 V supply reaches

Circuit Descrlption-SG 504

26 V, 0650 conducts and triggers 0660 on with the same results. Once 0660 is turned on, the i nstrument m ust be shut off and turned back on in order to reset this scr.

23 V Oscillator Supply

�

Current from the fl oati ng 25 V ac supply i n the main­ frame is bridge rectified by CR6 1 0. A pproximatel y -23 V is added to - 1 8 V provi d i ng about -41 V for the FM circuitry, as well as supplyi ng about -39 V with respect to ground, to t he emitter of the npn series-pass transistor l ocated in the mai nframe. This-41 V and -39 V i ncreases by about 2 V when switching to the reference oscillators from the high or low vari able frequency cavity oscillators.

Resistors R624 and R625 provide - 1 0 V at the base of

0620. Transistors 0620 and 0630 form an emitter­ coupled pair that operates as a voltage comparator.

Resistors R630 and R634 establish the - 1 4 V supply voltage at t he col lector of 0630 when 0640 is biased off.

Regulator VR640 is the -6.2 V reference for the base of

0640. Voltage from the leveling ampl ifier is fed i nto the emitter of this same transistor to shift the oscillator supply more negative. I ncreased voltage is obtained from this supply when the voltage at pin 6 of U295 ranges between about -5 V and O V. When 0640 turns on, 0630 reduces conduction; 0620 and the npn series-pass transistor in the mai nframe i ncrease conduction. This continues up to the point where the leveling amplifier is balanced, or the oscillator supply reaches the -23 V level and 0640 saturates.

When the current through R61 5 exceeds approximately

60 mA, VR6 1 5 conducts. This stops the base of the series­ pass transistor from goi ng more positive, thus limiting the amount of current available for t he osci llators to about

55 mA.

+S V Supply

�

The +5 V supply is derived from the + 1 1 .5 v supply which is in turn supplied by the power module. The

+1 1 .5 V supply is the i nput for U570, which i s the +5 volt reg ulator. I ntegrated circuit U570 contains a current­ limiting feature that starts to function at the 1 . 5 A level.

The POWER pi l ot lam p operates from t he +5 V suppl y and remai ns on as long as power is applied to instrument, even though the other supplies may be shut down by overload.

DIAG RAMS AN D CI RCU IT BOARD I LLUSTRATI O NS

Symbols and Reference Designators

Electrical components shown on the diagrams are i n the following units unless noted otherwise :

Capacitors = Val ues one or greater are in picofarads ( p F ) .

Resistors =

Val ues less than one are in microfarads (µ F ) .

Ohms (.Q).

Graphic symbols and class designation letters are based on ANSI Standard Y32.2-1 975.

Logic sy mbology is based on ANSI Y32. 1 4-1 973 in terms of positive logic. Logic symbols depict the logic function performed and may differ from the manufacturer's data.

The overl ine on a signal name indicates that the signal performs its i ntended function when it goes to the low state.

Abbreviations are based on ANSI Y1 . 1 - 1 972.

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

Y1 4.1 5, 1 966

Y1 4.2, 1 973

Y1 0.5, 1 968

Drafting Practices.

Line Conventions and Lettering. letter Symbols for Quantities Used in Electrical Science and
