BLOCK DIAGRAM IV OPERATION 4-9. INTRODUCTION. DESCRIPTION. Figure 4-1 shows the block diagram for the The Input signal is applied to the high and low frequency ampliliers. The high frequency amplifier (QlOl) amplifies the ac signal; the low frequency am plifier (Ql08 through QII0) amplifies the dc and low frequency signals. The ampllIied input signal is then applied through the dUferential amplifier (QI02 and Ql03), amplifier (QI04). and driver ampliller (Ql05) to emitter followers (Ql06 and QI07). Power ampli fiers Ql andQ2 (driven by Ql06) and Q3 and Q4 (driven by Ql07) provide a b..1.lanced signal to the OUTPUT connectors. 4-7. At frequencies above 1 MHz, negative feedback from the driver amplifier QI05 Is applied to QIOl through C122 and R129 to provide a decrease in dis tortion and remove the power amplifiers from the feedback loop. Negative feedback from QI05 Is applied to dlfferentlalampllflers QI02 and QI03 through R120. C 1 1 5 and R119 to improve frequency response of the Instrument. Gain control for high frequency ampUfier Q 1 0 1 Is supplied from the output of the power amplifiers (QI through Q4) through R148 and R130. 4-8. At frequencies between dc and 50 KRz, negative feedback Crom the output provides dc gain control and balance adjust for the low frequency amplifiers QI08 through QIlO.

Section IV SCHEMAIIC DIAGRAM DECRIPTlON. 4-10. The following paragraphs give a detailed descrip tion of the �1odel 467A Amplllier circuits. Refer to Figures 5-13 and 5-14, Section V, for the schematic diagrams of the Instrument. 4-11. HIGH FREQUENCY AMPLIFIER. 4-12. Trimmer capacitors C301, C303 and C305 can be adjusted to provtde the desired frequency response characteristics for the instrument. Ac input signals from the attenuator are applied through CIO! to the high frequency amplifier Ql01. The signal Is amplified by QIOI and coupled through CI04 to the base circuit of QI02. The RC networks, CI05, R112. Cl06 and R1l4 are used to Improve the frequency response characteristics orthe amplifier QI02. The bias volt age of QI01 Is determined by resistive divider RI03 and R104. Ac feedback from power amplifiers (Ql, Q2, Q3, and Q4) is applied through R148 to provide ac gain adjust for QIOI. 4-13. LOW FREQUENCY AMPLIFIER. 4-14. When the AMPLIFIER/SUPPLY selector Is in the SUPPLY poSition, +7 and -7 volts are suppUed from an Internal reference. through resistive diViders, to the ampliCier Input. Each SUPPLY position (-:1:1, :1:.2, :1:.4, :1:.10 and :1:.20) permits setting the dc output voltage to any ± value within the range selected. The low frequency amplifier circuit (Ql08. Ql09 and QUO) am plifies the dc and low frequency input signal and drives Ql03. The bias voltage fol' the low frequency amplifier is controlled by R132 and R133 and the ZERO control R5. TranSistor Ql10 is a current source for the dif ferential amplifiers QI08 and QI09. Inductors LIOI and Ll02 control the frequency response of the low frequency amplifier (at higher frequencies) by causing degeneration of QI08 and QI09 emitters. High fre quencies present at QI09 collector are shorted to ground by CI09. Low frequency stabilization and over· all amplifier gain (between dc and 50 KHz) are provided by applying dc feedback from the OUTPUT to QI09 base. The ZERO potentlometer R5 provides an adjust ment to compensate for dc drift in the instrument. VaryingR5 changes the voltage at QI09 base. thereby changing the output level of the low frequency ampli fier. 4-15. DIFFERENTIAL AMPLIFIER. 4+16. Differential ampllCiers QI02 and QI03 provide an output proportional to the input signals from the high frequency amplifier QIOl and the low frequency amplifier circuit (Ql09 and QIlO). The high fre Quency nc signals are coupled to QI02 through CI04; the dc and low frequency signals Crom the low fre quency amplifier are direct-coupled to differential amplifier QI03. capacitor CI08 bypasses any high frequency ac from the low frequency amplifier to 4-1 Mcdel 46'7A Section IV ground. CI09 bypasses any high frequency signals present at the Case of QI03. Ac feedback from QI05 collector circuit ill applied through ellS to the balle circuit of QI02 for high frequency gain stabillzation. 4-17. VOLTAGE AMPLIFIER. 4-IB. The voltageampUfierQI04 supplies the majority of the voltage gain for the Instrument. Degeneration at low frequencies Is provided by R12'7 In the QI04 emitter circultj CI16 provides added phase stability at high frequencies. Current through R125 provides the bias current for QI05. Breakdown diode CRI04 establishes the proper voltage at QI04 collector and maintains a dc signal path from QI04 Collector to QI05 base. 4-19. DRIVER AMPLIFIER. 4-20. Driver amplHierQI051s driven by current am plifier QI04 and supplies the signai to the power out put ampliHers. Transistors QI06 and QI07 are for ward biased bydiodesCRIOB through CR112and under no-signal condition are conducting slightly to reduce cross-over dlst::lrtion In the output signal. 4-21. OUTPUT cmculTs. 4-22. Transistors QI through Q4 provide a comple mentary symmetry output. QI and Q2, driven by emitter followerQI06, provide a low output impedance. Q3 an<! Q4, driven by QI07, form a unity gain feed back amplifier. ThlscausesQ3and Q4 t o a c t a s a PNP emitter follower, which is necessary to provide the complementary symmetry output. 4-25. 4-24. The external load connected to the 46'7A is pro tected during turn-on and turn-off. from current surges and voltage transients. by relay KI. The relay con tacts open the circuli totheO UTPUT connectors when the relay Is de-energized. When the instrument is turned ON, Kt remaln� de-energized lor about 300 milliseconds. This delay permits the instrument to stabilize before the output Is connected to the load. The 300 millisecond delay Is caused by the RC time constant of CIIO and RI6I. When the Instrument Is turned off. the relay quickly de�energlzes and opens the circuit to the OUTPUT connector. SUPPLY CIRCUIT -1-26.

Transistor QI12 In conJunCUon with R156, CR129, and CR130 provide a constant current source which provides base drive for Q5 and Q6. Q1l2 also provides current to keep CR131, CR132, CRI33, and CRI35 conducting. R2 and Q5 share the load current to reduce the dissipation In Q6. F o r small load currents Q5 Is turned off and resistor R2 supplies the current. As the load current Increases,the base of Q5 Is forward biased and Q5 conducts, sharing the current. As the load current Is Increased further, CR1341s forward biased at a current level determined by R159. This will reduce the current in CRI35 to zero causing the supply voltage to go to zero also. 4-29. PLUS 34 VOLT SUPPLY. 4-30.

The assembly -hp part number Is silk screened on the exterior of the Circuit board to idenllfy it. Refer to Section VI for parts replacement and -hp- part number information. 5-40. The etched circuit boards are a pL'lted-through type. The electrical connection between sides of the board Is made by a layer of metal plated through the component holes. When worklng on these boards, observe the following general rules. a. Use a tow-heat (25 to 50 watt) small-tip soldering iron, and a smaU diameter rosin core solder. b. Circuit components can be removed by placing the soldering iron on the component lead on either side of the boards, and pulling up on lead, If a component is obviously damaged, clip leads as close to component as possible and then remove. Excess heat can cause the 5-8 Circuit and board t o separate, or cause damage to the component. c. Component lead hole should be cleaned before inserting new tead. d. To replace components , shape new leads and insert them in holes. Reheat with iron and addsolder as required to Insure a good etec irlcal connection. e. Clean excess !lux from the connection and adjoining area. f. To avoid surface contamination of the printed circuit, clean with weak solution of warm water and mild detergent after repair . Rinse thoroughly with clean water. When completely dry, spray UghUy with Krylon (tl302 or equi valent).
