This section contains general information about the Model 3400A RMS Voltmeter (Figure 1-1). Included are: description of instrument, purpose, instrument identification, equipment supplied and accessory equipment available. Also included is a table of instru- ment specifications. 1-3, DESCRIPTION AND PURPOSE 14. The Model 3400A RMS Voltmeter measures the actual root-means-square (RMS) value of ac voltages between 100 microvolts and 300 volts. Frequency range is from 10 Hz to 10 MHz. Full scale measurements of nonsinusoidal waveforms with crest factors (ratio of peak voltage to rms voltage) of 10 can be made. 1-5. Ac voltages are measured with a specified full-scale accuracy of +1% from 50 Hz to 1 MHz, +2% from 1 MHz to 2 MHz, + 3% from 2 MHz to 3 MHz, and + 5% from 10 Hz to 50 Hz and 3 MHz to 10 MHz. A single front panel control selects one of 12 voltage or decibel ranges. 1-6. The Model 3400A crest factor rating is 10:1 which enables full scale readings for pulses which have a 1% duty cycle. At 1/10th of fuii scale, pulse trains with 0.01% duty cycle (100:1 crest factor) can be accurately measured. 1-7, The Model 3400A provides a dc output which is proportional to the front panel meter reading. By using this voltage to drive auxiliary equipment, the Model 3400A functions as an rms ac-to-dc converter. 1-8. SPECIFICATIONS 1-9. Table 1-1 contains the specifications for the Model 3400A. 1-10. INSTRUMENT AND MANUAL IDENTIFICATION I-11. Hewlett-Packard uses a two-section serial number. If the first section (serial prefix) of the serial number on your instrument does not agree with those on the title page of this manual, change sheets supplied with the manual will define the differences between your in- strument and the Model 3400A described in this manual.

This section contains identification of controls and in- dicators, turri-on procedures, and operating instructions. Also included 1s a discussion of the applications for the Model 32004. 3-3. CONTROLS AND INDICATORS 3-4. Each operating control, connector, and indicator located on the Model 3400A is iden- LE) rd L ITA tified and described in Figure 3-1. The description of each component is keyed to an illustra- tion of that component which is included within the figure. 3-5. TURN ON PROCEDURE 3-6. To turn on the Model 3400A, proceed as follows: a. Set 115/230 switch (7, Figure 3-1) to correct position for input line voltage. b. Apply ac voltage to Model 3400A by plugging power cord into input power jack (8) ac receptacle. c. Operate power switch (4) to ON; ensure that LINE indicator (3) lights. NOTE Allow five minutes for the Model 3400A to warm up and stabilize before making a reading. 3-7. OPERATING INSTRUCTION *CAUTION y | Do not measure signal above 80 volts with 10 to 1 crest factor. Otherwise, the maximum input rating (800 volts peak) will be ex- ceeded. When measuring signals up to 80 volts RMS with a 10 to 1 crest factor, use the BNC to dual banana Jack, accessory 101 104, supplied with the instrument, or other input test leads and connec- tions that will withstand the maximum input af 800 volts peak. 3-8. To operate the Model 3400A as an rms voltmeter proceed as follows: a. Attach test lead to INPUT connector (6, Figure 3-1). (See Table 1-3 for a list of test leads available.) e E re a Tae ry ent rT Hi} es rca RT Ae 3 т To ER Se Tl E AN E net i TE e er Rn Tr i Spt a tem Te у г Ah An a a i Ea ik 1 frre) ume, rk ло e ; se Tun EE | Ca Cea ay e Ш ma aL Ena A МТ CRATER nn En Operating Instructions b. Set RANGE switch (5) to 300 VOLTS position. É | ÉCAUTION When measuring an ac signal superimposed on a DC level, always set the range switch to the 300 volt position.

Rotate RANGE switch counterclockwise until meter (1) indicates on upper two thirds fea of scale. 3-9. APPLICATIONS a O | 3-10. The Model 3400A can be used in conjunction with other test instruments to measure the rms value of ac signal with a de component, measure rms current and act as an rms ac-to- de converter. For additional information on special applications, contact your -hp- Sales and Service Office. | 3-11. RMS Value Df AC Signals With DC Component x 3-12. Since the 3400A is an ac device it will measure only the rms value of the ac component. | | If it is necessary to include the rms value of the de component when measuring a signal use - an -hp- Model 3468A Digital Multimeter to measure the de component. Substitute the | reading from the Model 3468A and Model 3400A in the following formula: The ac signal (up | to 800V peak) may be superimposed on a dc level of up to 600 Y. | | O ms = Cpe + e E 3-13. RMS Current | 3-14. To measure rms current, use an -hp- Model 456A AC Current Probe. This probe clips in around the current conductor and provides an output voltage that is proportional to the cur- 3 ES rent being measured. Using this method, rms currents of one milliampere to one ampere can y be measured. | 3-15. RMS AC-To-DC Converter | 3-16. Since the Model 3400A is provided with a dc output (10, Figure 3-1) which is propor- | tional to the meter deflection, it can be used as a linear rms ac to dc converter. The dc output | can be used to drive an -hp- Model 3468A Digital Multimeter for high resolution за measurements and/or an -hp- Model 680 Strip Chart Recorder, External loading does not р affect the meter accuracy so that both the meter and dc output can be used simultaneously.

INTRODUCTION 4-2. This section contains the theory of operation of the Model 3400A RMS Voltmeter. In- cluded is a general and detailed description of the theory of operation. 43. GENERAL DESCRIPTION 4-4. The operation circuitry of the Mode! 3400A consists of two attenuators, an impedance converter, a video amplifier, a chopper op amp, a thermocouple pair, and a direct reading + HIETCT, 4-5. A signal being measured with the Model 3400A is applied to input attenuator Al through the INPUT jack, located on the Model 3400A front panel. The input attenuator has an input impedance of over 10 megohms and provides two ranges of attenuation. The out- put of the input attenuator is applied to impedance converter A2. The impedance converter is a non-inverting unity voltage gain amplifier. It presents a high impedance to the input signal and provides a low impedance output to drive the second attenuator A3. The second attenuator provides 6 ranges in a 1, 3, 10 sequence. The two attenuators are switched to pro- vide 12 ranges of attenuation. 4-6. The output of the second attenuator is amplified by video amplifier A4. The video amplifier is a wideband, five stage amplifier. The overall gain of the video amplifier is con- trolled by an ac feedback loop. The ac output of the amplifier is applied to TC401; one of the thermocouples of the thermocouple pair. | 4-7. The de output of TC401 is applied to the chopper op amp (U601) which modulates the voltage. The resultant modulated signal is then amplified and, after the amplification, the signal is demodulated back to de volts. This voltage is the output of the chopper op amp. Tne value of the voltage is proportional to the de input voltage. 4-8. The output of the chopper op amp is applied to a filter and also to TC402, the second thermocouple of the thermocouple pair. The output of the filter is applied to an output amp (A4) which is used to drive the meter (М1). 4-9. The thermocouple pair TC401 and TC402 acts as a summing point for the ac output of the video amplifier (A4) and the dc output of the chopper op amp. The difference in the heating effect of these voltages is the dc input to the chopper op amp. This difference input 1s amplified and is fed to TC402 and also, after going through the output amplifier (U602), to the meter (MI), This voltage represents the rms value of the ac signal applied to the 3400A’s INPUT jack. By using two “matched” thermocouples and measuring the dif- ference, the output of the chopper op amp will be linear. Using two thermocouples also pro- vides temperature stability. о Theory of Operation Model 3400A —_——,——— a —— | la © aa aaa 0 | - e „7 ‚ , # A 1 и” и” INP 2 TC40 | | INPUT | IMPEDANCE SECOND VIDES + ATTEN —— CONVERTER —— ATTEN AMPLIF ER - Al A2 АЗ A4 E.

The input attenuator assembly is a capacitive-compensated attenuator which provides | | two ranges of attenuation for the 12 positions of the RANGE switch. See input attenuator | | schematic diagram illustrated on Figure 6-1. | | 4-14. When the RANGE switch is positioned to one of the six most sensitive ranges (.001 to ET .3 VOLTS), the attenuator output voltage is equal to the input voltage. When the RANGE oa | switch is positioned to one of six highest ranges (1 to 300 YOLTS), the input signal is at- tenuated 60 dB (1000: 1 voltage division) by the resistive voltage divider consisting of R101, a R103, and R104. Trimmer C102 is adjusted at 100 kHz, and R104 is adjusted at 400 Hz to | provide constant attenuation over the input frequency range. Model 3400A Theory of Operation 4-15. Impedance Converter Assembly A2 4-16. The impedance converter assembly utilizes a nuvistor tube cathode follower circuit to match the high output impedance of the put attenuator to the low input impedance of the second attenuator. The cathode follower circuit preserves the phase relationship of the input and output signals while maintaining a gain of unity. See impedance converter assembly schematic diagram illustrated on Figure 6-1. 4-17. The ac signal input to the impedance converter is RC coupled to the grid of cathode follower V201 through C201 and R203. The output signal is developed by Q201 which acts Pie. TN as a variable resistance in the cathode circuit of V201. The bootstrap feedback from the E cathode of V201 to R203 increases the effective resistance of R203 to the input signal. This | prevents R203 from loading the input signal and preserves the high input impedance of the Model 3400A. The gain compensating feedback from the plate of V201 to the base of Q201 compensates for any varying gain in V201 due to age or replacement. 4-18. Breakdown diode CR201 controls the grid bias voltage on V201 thereby establishing the operating point of this stage. CR202 and R211 across the base-emitter junction of Q201 protects Q20! in the event of a failure in the +75 volt power supply. Regulated dc is sup- plied to V201 filaments to avoid inducing ac hum in the signal path. This also prevents the gain of V201 changing with line voltage variations. 4-19. Second Attenuator Assembly A3 4-20. The second attenuator is a resistive divider which attenuates the ac input signal while maintaining a low impedance ouiput for the following amplification stages. See second at- tenuator assembly schematic diagram illustrated in Figure 6-1. 4-21. The ac input signal is applied to a precision resistance voltage divider consisting of R302 through R312. These resistors are arranged to give six ranges of attenuation at 10 dB per range. The six ranges of the second attenuator combined with the two ranges of the input attenuator make up the 12 ranges of attenuation (0.001 to 300V). Trimmer capacitor C303 (10MHZz 0.3V ADJ) provides an adjustment for frequency response at the higher frequen- cies. 4-22. Video Amplifier Assembly A4 4-23. The video amplifier functions to provide constant gain to the ac signal being measured over the entire frequency range of Model 3400A. See video amplifier assembly schematic diagram illustrated on Figure 6-2. 4-24. The ac input signal from the second attenuator is coupled through C402 to the base of input amplifier Q401. Q401, a class A amplifier, amplifies and inverts the signal which is then direct coupled to the base of bootstrap amplfier Q402. The output, taken from Q402 emitter is applied to the base of Q403 and fed back to the top of R406 as a bootstrap feed- vack. This positive ac feedback increases the effective ac resistance of R406 a dh e Te lowing a greater portion of the signal to be felt at the base of Q402. In this manner, the effective ac gain of Q401 is increased for the midband frequencies without disturbing the static operating voltages of Q401. Ш Theory of Operation Model 3400A 3 4-25. Driver amplifier Q403 further amplifies the ac signal and the output at Q403 collector | is fed to the base circuit emitter follower Q404. The feedback path from the collector of | Q403 to the base of Q402 through C405 (10 MHz ADJ) prevents spurious oscillations at high xX input frequencies. A dc feedback loop exists from the emitter circuit of Q403, to the base of | | Q401 through R425. This feedback stabilizes the Q401 bias voltage. Emitter follower Q404 | acts as a driver for the output amplifier consisting of Q405 and Q406; a complimentary pair operating as a push-pull amplifier. The video amplifier output is taken from the collectors of the output amplifiers and applied to thermocouples TC401. A gain stabilizing feedback is developed in the emitter circuits of the output amplifiers. This negative feedback is applied to the emitter of input amplifier Q401 and establishes the overall gain of the video amplifier. E. 4-26. Trimmer capacitor C405 is adjusted at 10 MHz for frequency response of the video as amplifier. Diodes CR402 and CR406 are protection diodes which prevent voltage surges a from damaging transistors in the video amplifier. CR401, CR407, and CR408 are qe temperature compensating diodes to maintain the zero signal balance condition in the out- co put amplifier over the operating temperature range. CR403, a breakdown diode, establishes | the operating potentials for the output amplifier. 4.27. Chopper Op Amp Assembly AS And Thermocouple Pair (Fart Gf Ad) 4-28. The chopper op amp and thermocouple pair form a servo loop which functions to position the direct reading meter M1 to the rms value of the ac input signal. The chopper op amp and thermocouple pair schematic diagram is illustrated in Figure 6-3. | | 4-29. The video amplifier output signal is applied to the heater of thermocouple TC40i. Wor This ac voltage causes a dc voltage to be generated in the resistive portion of TC401 which is va pi ote FR ane Me Nn = EP ét A proportional to the heating effect (rms value) of the ac input. The dc voltage is applied to the a = fi chopper op amp. | ; and output ainp (U602). The chopper op amp is a high gain low drift op amp and is used e o modulate the applied dc voltage, amplify the voltage, and then demodulate the voltage | | back to de (the output voltage of the amplifier). The output of the amplifier is the ac stabilizing ' and summing feedback for thermocouple TC402, and is also applied to the filter. The ac stabilizing feedback (using R614, R615, and C605) is used to prevent the circuitry from oscillating. ny 4-30. The chopper op amp assembly consists of a chopper op amp {U601), filter, oscillator, | | 4-31. The oscillator consisting of Q601, Q602, and associated circuitry, is used to reduce the | noise of the chopper op amp. It operates at a frequency of approximately 2K Hz. | | 4-32. The output from the chopper op amp (summing feedback) is applied to the heating a element of thermocouple TC402. The dc voltage developed in the resistive portion of TC402 is effectively subtracted from the voltage developed by TC401. The input signal to the chop- | | Ш per op amp then becomes the difference in the dc outputs of the two thermocouples. When ВЕ the difference between the two thermocouples becomes zero, the dc output from the chop- per op amp will be equal to the ac from the video amplifier. | | g 4-33. The filter, consisting of R617, R618, R619, C607 and C608, is used to further reduce ВЫ the noise on the output of the chopper op amp. This is to make the meter reading quiet. | | | | | 4-34. The output of the filter is connected to the output amp (U602). The purpose of the | : E amplifier is to drive the meter (M1) and to provide a low impedance output for the rear D.C. RIE OUT connector. The output impedance of the amplifier is approximately 1 ohm. Since there Model 3400A Theory of Operation are two 499 ohm resistors (R624 and R631) between the amplifier output and the rear ter- minal, the output impedance at the terminal is approximately 1000 ohms. 4-35, Other circuits, consisting of C611, R629, and R630, are used to speed up the step response of the 3400A. 4-36. Power Supply Assembly A7 4-37. The power supply assembly provides dc operating voltages for the tube and transistors used in the Model 3400A. See power supply assembly schematic diagram illustrated on Figure 6-4. , 4-38. Either 115 or 230 volts ac is connected to the primary of power transformer T1 through fuse F1 and the POWER switch S1. Switch S2 (slide switch on rear panel) connects T1 primary windings in series for 230-volt operation or in parallel for 115-volt operation. Neon lamp DSI lights to indicate LINE power ON when ac power is applied and S1 is closed. 4-33. Regulator Operation 4-40. The series regulator acts as a dynamic variable resistor in series with the power supply output. A control amplifier senses changes in the output voltage by comparing the output with a fixed reference voltage. The control amplifier then supplies any output voltage changes to the driver transistor, which in turn changes the resistance of the series regulator to oppose the change in output voltage. Diodes CR704, CR713 and CR706 across the base emitter junction of the series regulator provide overload current protection. 4-41. +75 Volt Supply 4-42. The +75 volt supply consists of a full-wave rectifier (CR701 and CR702) whose out- put is filtered by CIA and CIB and regulated by series regulator Q1. The +75 volt supply provides regulated +75 volts which is used as the plate supply voltage for V201. Voltage variation from the output is felt at Q702 base circuit through C704, R715, and R716. The C703 and R709 network provides phase correction for power supply stability. The regulation circuitry is in the negative leg of the + 75 volt supply, and uses the -17.5 volt supply as a reference. 4-43, —17.5 Volt Supply 4-44. The regulated — 17.5 volt supply consists of a full-wave rectifier (CR711, and CR712) whose output 1s filtered by C706 and C707 and regulated by Q2. Breakdown diode CR715 provides reference voltage at the base of Q704. Regulation operation is the same described in Paragraph 4-40. 4-45, —6.3 Volt Supply 4-46, The regulated — 6.3 volt supply consists of a full-wave rectifier (CR716 and CR717) whose output is filtered by C2 and regulated by Q3. Emitter follower Q705 is connected to the — 17.5 voit supply which provides a reference for the — 6.3 volt supply. Series regulator Q3 acts as a dynamic variable resistor in series with the output to oppose changes in output voltage. 4-5/4-6 I | ИН, pp he | ||: | I i 1 | | Poo . | | La | | = Ar | WARNING À LE | В Maintenance described herein is performed with power supplied to | | | | | the instrument, and protective covers removed.

TROUBLESHOOTING PROCEDURES 3-31, This section contains procedures designed to assist in the isolation of malfunctions. These operations should be undertaken only after it has been established that the difficulty cannot be eliminated by the Adjustment and Calibration Procedures, Paragraph 5-15. An investigation should also be made to ensure that the trouble is not a result of conditions ex- ternal to the Model 3400A. | 5-32. Conduct a visual check of the Model 3400A for possible burned or loose components, loose connections, or any other condition which might suggest a source of trouble. 5-33. Table 5-5 contains a summary of known problems by front panel symptoms. 5-34. Table 5-6 contains procedures which may be used as a guide in isolating malfunctions. The checks outlined in Table 5-6 are not designed to measure all circuit parameters, rather only to localize the malfunction. Therefore, it is quite possible that additional measurements will be required to completely isolate the problem. Amplifier gain and biasing may vary slightly from instrument to instrument; therefore, it should not be necessary to precisely duplicate waveforms or values described.

The following procedure will allow you to check the thermocouples for proper opera- tion in the -hp- Model 3400A RMS Voltmeter. NOTE This check will not yield any information concerning thermocou- ple operation for either sluggish or overshoot-undershoot response on 34004 meter. If a 3400A has the above symptoms replace ther- mocouples. 5-37. To perform these checks, supply SmA of current to the heaters of the thermocouples. This can be accomplished by connecting a 1K ohm resistor (-hp- Part Number: 0684-1021) in series with the output of a 5V dc power supply. Then connect the supply to the heater of thermocouple and measure the output voltage of the thermocouple with the Digital Multimeter. If the thermocouple fails any of the following tests, replace it using the pro- cedure in paragraph 5-37. Do the following: à. Turn the 3400A off and remove the A6 assembly. NOTE See Figure 6-3 for component locations. b. Set the multimeter to the ohms function. Connect the test leads between ground and the junction of C413 and C415 on the A4 assembly (this checks the resistance of the heater a in TC401). Make sure the reading on the multimeter is between 76.5 ohms and 103.5 ohms. If the reading is not within limits, replace the matched set of thermocouples (-hp- Part Number: 0853-0003). с. Remove the multimeter and, in place of the multimeter, connect the 5V dc power sup- ply between ground and the junction of C413 and C415. Turn the power supply on. Set the multimeter to the dc volts function and connect it as follows: Negative (low) input to pin 11 on the A6 socket. Positive (high) input to pin 13 on the A6 socket. The multimeter should display between +6.5mV and +9mV. Note the reading on the multimeter. If the reading is not within limits, replace the thermocouple pair. If the reading is within the test limits, remove the multimeter and set it to the ohms function. Then discon- 1ect the power supply and turn it off. © © O © © —() se O— (7 FAILS (18) © — © 19 (23 ® @ — © © 25 Figure 5-5. Troubleshooting Tree Table 5-6. Troubleshooting Procedure Check © © © © © © © Procedure Set the 3400A to the 1V range. Apply 1V, 400Hz ac signal to the input terminals. Measure the signal at junction of C413 and 415. The reading should be be- tween 240mV and 280mV RMS. Measure the signal between TP2 and TP1 on the A6 assembly. The signal! should look like the one in Figure 5-6. Troubleshoot and repair oscillator circuitry. Turn the 3400A off and place the A6 board on an ex- tender board. Unsolder and lift one end of R616 from the board (the de feedback is now disconnected). Set the instrument to the 1V range and apply a 1V, 400Hz RMS ac signal to the input terminals. Using a Digital Multimeter (like the 3468A), measure the voltage between TF3 and TP1 on the AS assembly. The voltage should be approx- imately 2mY to 2.5mY ac. Check for a defective TC401. TC401 may also be discon- nected from the output of the video amplifier via capacitors C4132 and C415. Turn the instrument off and replace and resolder R616 on the AB board. Make sure the 3400A is still on the 1V range and the 1V, 400Hz signal is still applied. Turn the instrument on and measure the voltage between TP4 and TP1 on the AS board. The voltage should ap- proximately be — 4V de. If the voltage is positive, check for a shorted CR6GS. !f the voltage is negative but other than —4Y, U60?2 or TC401 may be defective. Check the voitage between TF5 and TP1 and make sure it is —.19V. Troubleshoot the fitter circuitry consisting of R817 through R619, and C606 through C808. Check the voltage between TP6 and TP1 and make sure it is approximately —1V.

Thermocouple Replacement CAUTION Exercise extreme care when removing or replacing the amplifier printed circuit board assembly and when shaping the thermocou- ple leads. 5-39. Should a thermocouple be defective, it is necessary to replace both as a matched pair (see Section VII, Table of Replaceable Parts) for part number. To replace thermocouples, perform the following steps: a. Turn instrument power off and remove right side (INPUT side) and top covers. b. Remove the four lead connection to the À4 amplifier board. 1. Black coaxial cable (two leads) 2. Violet lead 3. White lead/blue lead. 5-14 Model 3400A Maintenance c. Remove the three mounting screws on the amplifier board. d. Gently pull bottom of board out at the same time relieving stress on thermocouple cable until the board will drop down and the top will clear main frame. Carefully fold board down to expose the four nuts holding the thermocouple shield. e. Remove four shield nuts; lift shield off. Remove thermocouples, noting orientation. f. Leads on new thermocouples must be shaped before inserting into PC board. During the shaping process, hold leads between bending point and glass with long-nose pliers. g. Place the red dots on the thermocouples face down on the Ad Video Amplifier Board. If one of the thermocouples has an additional colored dot place it in the TC402 position. h. Carefully insert new thermocouple leads and solder. 1. Reverse steps e, d, ¢, b. Note: the violet lead goes to the lower of the two top connec- tors on the A4 board. J. After thermocouple replacements perform a complete adjustment and calibration pro- cedure as outlined in Paragraph 5-15. + 5-40. SERVICING ETCHED CIRCUIT BOARDS 3-41.
