DO NOT TRY TO PULL OR GRAB THE INDIVIDUAL

IF POSSIBLE, TURN OFF THE ELECTRICAL POWER

IF YOU CANNOT TURN OFF THE ELECTRICAL POWER, PULL, PUSH, OR LIFT THE PERSON TO SAFETY USING A DRY WOODEN POLE OR A DRY ROPE OR SOME OT HER INSULATING MATERIAL

SEND FOR HELP AS SOON AS POSSIBLE

AFTER THE INJURED PERSON IS FREE OF CONTACT WITH THE SOURCE OF ELECTRICAL SHOCK, MOVE THE PERSON A SHORT DISTANCE AWAY AND

IMMEDIATELY START ARTIFICIAL RESUSCITATION

TM 11-6625-2495-14&P

WARNING Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE. Prolonged breathing of vapor should be avoided. The solvent should not be used near heat or open flame; the products of decomposition are toxic and irritating. Since TRICHLOROTRIFLUOROETHANE dissolves natural oils, prolonged contact with skin should be avoided. When necessary, use gloves which the solvent cannot penetrate. If the solvent is taken internally, consult a physician immediately.

WARNING When the output ground is floated above Power Line Ground, all BNC connectors will be at the offset voltage.

GENERAL INFORMATION

1-1. GENERAL.

1-7. OUTPUT SYSTEM.

1-2. The Hewlett-Packard Model 3300A Function

Generator is a solid state instrument useful for most general purpose frequency testing applications. Three output waveforms are available from front panel connectors; sine, square, and triangle. A sync pulse is also available from a rear panel connector.

1-3. The -hp- Model 3300A Function Generator is a type of relaxation oscillator. The triangle and square wave voltage functions are inherent in the oscillatory system. The sine wave is produced by synthesizing the triangle wave.

1-4. The -hp- Model 3301A Auxiliary Plug-in or another 3300A plug-in is required to provide internal connection for basic unit (main frame) operation.

1-8. The -hp- Model 3300A has two completely separate output channels. Each output is dc coupled and can be fully floating with respect to power line ground. An internal shield reduces radiated interf erence and provides common mode rejection with floating output. Separate connectors on the rear panel provide

terminals for circuit ground ( shield ground (

output ground may be floated from power line ground by up to +250 volts. Any two of the three waveforms are available simultaneously from the front panel connectors.

), output ground ( ),

1-5. ELECTRONIC FREQUENCY CONTROL. 1-6. Frequency of the -hp- Model 3300A can be

controlled by either the front panel frequency dial or an external voltage applied to a rear terminal connector. This feature is useful for sweeping filters, amplifiers and other frequency-dependent devices and for externally programming frequencies for production testing. An input voltage of approximately -0. 5 to -10 volts will linearly control the frequency over any one range (one decade).

If desired the frequency can be controlled over more than one decade, by applying a +0.3 to -10 volts to the FREQUENCY CONTROL BNC. A +0. 3 to -10 V input will linearly control the frequency over approximately a 50:1 range.

1-10. Hewlett-Packard uses a two-section serial number. The first section (prefix) identifies a series of instruments. The last section (suffix) identifies a particular instrument within this series. If a letter is included with the serial number, it identifies the country in which the instrument was manufactured.

1-11. If the serial prefix of your instrum ent differs f rom the one on the title page of this manual, a change sheet will be supplied to make this manual compatable with newer instruments or the backdating information in Appendix C will adapt this manual to earlier instr uments. All correspondence with Hewlett-Packard s hould inc lude the complete serial number.

Model 3300A Section IV

SECTION IV

THEORY OF OPERATION

4-1. INTRODUCTION. 4-2. This section contains a des cription of the theory

of operation of the -hp- Model 3300A Function Generator with the -hp- Model 3301A Auxiliary Plug-in.

4-3. GENERAL DESCRIPTION. 4-4. The Model 3300A contains a frequency control

network, two current sources, a triangle integrator, a voltage comparator multivibr ator, a sine wave synthesizer and output amplifiers. (Refer to Figure 4-1

4-5. The Model 3301A Auxiliary Plug-in provides internal connections which facilitate Model 3300A operation.

4-6. The voltage comparator multivibrator, current sources and triangle integrator form the basic function generating loop. The voltage comparator multivibrator changes state at predetermined lim its on the positive and negative slopes of the output of the triangular integrator. This change of state shuts off the upper current source, reverses the input to the triangle integrator. A cycle is as follows: when the amplitude of the positive slope of the triangle wave reaches the upper predetermined limit of the voltage comparator multivibrator, the multivibrator changes state. This change of state reverses the current into the triangle integrator through control of the upper current source which causes the output of the integrator to decrease. The decrease continues until the amplitude of the negative slope reaches the lower predetermined limit. At this point, the voltage comparator multivibrator changes state and again reverses the direction of current at the input of the integrator and causes the output of the

integrator to rise. This rise continues until the voltage comparator multivibrator again changes state thus completing the cycle.

4-7. The frequency control network, governed internally by the FREQUENCY Dial or externally through the FREQUENCY CONTROL, determines the amount of current in the current sources , which varies the frequenc y as follows: an increase or decrease in input current increases or decreases the slope of the triangle wave, respectively. (A change in direction of input current reverses the slope. ) Frequenc y will increase if the + and

- slopes are increased, as less tim e is required for the + or - slope of the triangle wave to reach the pr edeterm ined limits in the voltage comparator multivibrator.

4-8. The sine wave is synthesized from the triangle wave by a nonlinear network. This network consists of resistors and diodes biased so different diodes conduct during different voltage levels of the tr iangle wave. These diodes, when conducting, provide additional shunt paths within the network. Each additional shunt path changes the slope of the triangle wave so that the wave is shaped to a sine wave.

4-9. The output amplifiers are dc coupled and fully floating with respect to power line ground. CHANNEL A and CHANNEL B amplifiers are identical and use a differential amplifier at the input. To maintain the same peak-to-peak amplitude regardless of function selected, the overall closed loop gain of the amplifier is varied with function selection.

Figure 4-1. Block Diagram

4-1

Section IV Model 3300A 4-10. The sync pulse is produced by an RC

differentiating network. T he negative pulse at the output is in phase with the positive crest of the sine and triangle wave. 4-11. Power Supply (Refer to Figure 6-5) can operate on either 115 or 230 volts input and delivers 3 pairs of voltages, +40V, ±26.5V, and +

provides power for the oven heater. The 26.5 volt supplies are regulated and the 20 volt supplies are double regulated. 4-12. Critical temperature sensitive components are housed within an oven in which the temperature is maintained at approximately 800 C (1760 F).

4-13. SCHEMATIC THEORY. 4-14. FREQUENCY CONTROL NETWORK. 4-15. (Refer to Figure 6-2) T he FREQUENCY dial (R4)

in conjunction with the RANGE switch (S3) provides internal frequency control. The basic frequency equation can be expressed as F= i

where i is the current to the triangle integrator, C is the triangle integrator feedback capacitor and e out is the peak-to-peak voltage of the triangle wave. 4-16. The position of the RANGE switch determines the integrating capacitor C. The FREQUENCY dial or external control voltage determines the current i. The frequency control voltage is applied to the current c ontrol transistor Al IQ5, which establishes the am ount of curr ent available to the triangle integrator from the current sources AllQ6 and AllQ7.

4-17. CURRENT SOURCES. 4-18. The state of current source A11Q6 is controlled

by the voltage comparator multivibrator, and in turn, controls the direction of the current in the input of the triangle integrator. When A11Q6 is on, a current, 2 i, flows through it and divides, i into the integrator and i through current source A11Q7. When the bi-stable multivibrator changes state and gates A11Q6 off, 2 i no longer flows; however, the current through A11Q7 remains the same. Therefore, a current equal to i but opposite in direction flows from the triangle integrator input.

4-19. TRIANGLE INTEGRATOR. 4-20. The triangle integrator consis ts of an impedance

converter A11Q8 (a field effect transistor), a differential amplifier A13Q1 and A13Q2, an em itter follower A13Q3, diode A13CR1, and the capacitive feedback network : this circuit integrates the constant current inputs into the positive and negative slopes which mak e up the triangle wave. The triangle wave is applied to the inputs of the output amplifiers, sine wave synthesizer and voltage comparator multivibrator.

4-21. VOLTAGE COMPARATOR MULTIVIBRATOR. 4-22. The voltage comparator multivibrator consists of

a voltage comparator switching network, A14Q8, A14CR13 and A14CR14; a bi-stable multivibrator A14Q9 and Q10 and an emitter follower A14Q11. A14CR19 and

20V. The 40 volt supply

2C ∆ e out

R45 provide a low resistive path to ensure rapid rise and fall time of the square wave in the event the capacitance of the load is high. When the positive slope of the triangle wave reaches +20 volts, A14CR13 is turned on. A14Q9 is then turned on which turns A14Q10 off. The rise in the collector voltage of A14Q10 is coupled through emitter follower A14Q11 and through A14CR20 and A14CR21 into the emitter circuit of A11Q6, and turns it on. The output slope then becomes negative. A11Q6 rem ains on until the negative slope reaches zero volts. At the zero point on the negative slope A14CR14 is turned on which causes the bi-stable multivibrator to c hange state so that A14Q9 is now off and A14Q10 is on. The decrease in A14Q10 collector voltage gates the current source, A11Q6, off which reverses the integrator input current. The positive slope then begins increasing toward the upper limit, +20 volts. The output of the emitter follower is differentiated by A14C7 and A14R48 to provide the sync output. A negative sync pulse occurs at the crest of sine and triangular wave, see Figure 4-1.

4-23. SINE WAVE SYNTHESIZER. 4-24. (See Figure 6-2) The sine wave synthesizer

comprises four control transis tors, the biased diodes with associated voltage dividers, a differential amplifier A14Q5, A14Q6 and the output amplifier A14Q7. A14R17 andA14R29 adjust the operating points of the voltage dividers to minimize distortion. T he diodes are biased by the four control transistors A14Q1 through A14Q4 and the voltage dividers to provide twelve different current paths in the input to the differential amplifier as the triangle wave progresses. Each slope of the triangle wave is modified in twelve steps so that the waveform appearing at the base of A14Q5 approximates a sine wave. The sine wave synthesizing network is isolated by the differential amplifier A14Q5 and A14Q6 and amplifier A14Q7.

4-25. OUTPUT AMPLIFIERS. Figure 6-4). 4-26. The etched circuit assemblies A15 and A16 are

identical. CHANNEL A and CHANNEL B differ due to the

-A output of CHANNEL B. The input for CHANNEL B with its function switch in -A position, A16 Pin 5, is taken from the junction of A15R20 and R21, XA15 Pin 11. The output amplifiers are variable gain amplifiers. Gain is varied by changing the amount of feedback for the different functions. The following reference designators should be prefixed by applicable assembly number . The feedback is varied by resistors R1 through R5 and R23 C8 combination, to maintain equal peak-to-peak amplitude of the various functions for a given AMPLITUDE control setting. A differential amplifier, Q1 and Q2, make up the first stage f ollowed by two additional amplifiers Q3 and Q4. The trim mer C2 in the feedback network is used to shape the square wave. The AMPLITUDE control provides a nom inal 600 ohms output impedance, independent of amplitude control setting.

4-2

Model 3300A Section IV 4-27. POWER SUPPLY (Figure 6-5). 4-28. The power supply consists of two full wave

rectifiers CR1 thru CR4 and four series regulated supplies. AllCR1 provides a stable referenc e for the two negative regulated supplies which in turn are the references for the two positive regulated supplies. The two 20 volt supplies are double regulated. The operation of the four supplies is similar: A differential amplifier senses and amplifies any change. The change is applied through a driver stage to the series regulator which then changes its conduction to oppose the change.

4-29. Operation of the positive and negative supplies is similar. Diodes CR2 thru CR5 and CR7 thru CR9 determine the maxim um current permitted to f low in the series regulating transistors. Referring to Figure 6-5, +26.5 volt supply, it can be seen that an increase in current through R5 and R6 increases the overall for ward bias on the diode network CR2 thru CR5. The magnitude of this forward bias is determ ined by the sum of the forward biased base-emitter diode voltage of Q1 and Q2 in addition to the voltage drop across the R5-R6

combination. When this forward bias increases to a level sufficient to allow the diodes to conduct, any increas e in the collector current of Q4 will pass through the diodes and not enter the base of Q2. This, in thru, limits the maximum current in the series regulating transistors.

4-30. OVEN. 4-31. (See Figure 6-5.) The desired oven temperature

is automatically maintained by a thermal control loop. The loop consists of a thermistor, a signal amplifier, a power amplifier, and the heater resistors. T he operation of the loop is as follows: The resistance of RT1 (thermistor) decreases with an increase in temperature which causes the base current of A11Q9 to increase. The corresponding decrease of A11Q9 collector voltage is coupled into the base circuit of the power amplifier Q7. The collector current of Q7 then decreases which decreases the current through the heater resistors generating less heat and the temperature decreases. The response of the loop is improved by the physical location of A11R27 in close proximity to the thermistor.

5-43. REPAIR PROCEDURES. 5-44. SERVICING ETCHED CIRCUIT BOARDS. 5-45. The Model 3300A has six etc hed circuit boards.

Use caution when removing them to avoid damaging mounted components. The -hp- Part No. for the assembly is marked on the circuit board to identif y it and on the appropriate schematic. Refer to Section VII for replacement -hp- Part No’s. The etched circuit boards are of the plated-through type. The electr ical connec tion between the two sides of the board is made by a layer of metal plated-through the component hole. When working on these boards, observe the following rules:

a. Use a low-heat (25 to 30 watts) small-tip

soldering iron, and a small diameter rosin

core solder. b. Remove circuit components by placing the

soldering iron on the component lead on

either side of the board, and pulling up on

the lead.

If a component is obviously damaged, clip

leads off as close to the component as

possible and then remove leads with a

soldering iron.

CAUTION EXCESSIVE HEAT CAN CAUSE THE CIRCUIT AND BOARD TO SEPARATE, OR CAUSE DAMAGE TO THE COMPONENTS.

c. Clean com ponent lead hole by heating the

hole with the iron and inserting a wooden toothpick. Remove the toothpick after the solder has cooled and insert the new component lead.

d. Shape the new components leads and

insert them in lead holes. Reheat with soldering iron and add a small amount of new solder as required to insure a good electrical connection.

e. Clean excessive flux from the connection

and adjoining area.

5-6

Model 3300A Section V

CAUTION TO AVOID SURFACE CONTAMINATION OF THE PRINTED CIRCUIT, CLEAN WITH A WEAK SOLUTION OF WARM WATER AND MILD DETERGENT AFTER REPAIR. RINSE THOROUGHLY WITH CLEAN WATER AND ALLOW IT TO DRY COMPLETELY BEFORE OPERATING. DO NOT USE ALCOHOL OR ANY OTHER CLEANING SOLUTION EXCEPT DETERGENT AND WATER. DO NOT APPLY ANY COMMERCIAL MOISTURE SEALING SPRAY TO T HE BOARDS. APPLICATION OF THESE AGENTS WILL CAUSE LEAKAGE PATHS AND SUBSEQUENTLY, DETERIORATION TO THE OPERATION OF THE INSTRUMENT.

f. Wear c lean, lint f r ee cotton or rubber gloves

when handling the circuit boards. Avoid touching the board or components with bare fingers as skin oils can cause contamination and leakage paths.

5-46. SERVICING ROTARY SWITCHES. 5-47. The 3300A has three rotary type switches;

RANGE, CHANNEL A, and CHANNEL B. When working on these switches, observe the following rules:

a. Use a low-heat (25 to 50 watts) small tip

soldering iron, and a small diameter rosin core solder.

b. When replacing components, attempt to

dress them as nearly to their original alignment as possible.

c. Clean excessive flux from the connection

and adjoining area.

5-48. REPLACEMENT OF FACTORY SELECTED COMPONENTS. 5-49. Replacement components are identified in Table

5-3 and 5-6. Should it become necess ary to replace any of the capacitors in the feedback circuit of the Triangle Integrator, the replacement capacitor (a good quality polycarbonate or mica film type) must be selected so that the approximate parallel capacitance is as indicated in

Table 5-3. If after capacitor replacement, the resultant frequency is not correct, the necessary capacitor change can be determined by the following formula:

correction = C feedback

(Freq - desired Freq X100

desired Freq

Example: X1K range inaccurate

Freq of 9.8 kHz (Range X1K dial 10)

correction = 0.011 µF

(9.8K - 10K) X100

10K

= -0.011 µF = -.00137 µF

5-50. TROUBLESHOOTING PROCEDURE. 5-51. This section contains procedures designed to

assist in the isolation of a malfunction. These procedures are based on a systematic analysis of the instrument in an effort to localize the problem. These operations should be undertaken only after it has been established that the difficulty cannot be eliminated by the adjustment and calibration procedures outlined in Paragraph 5-21. 5-52. Conduct a visual check of the 3300A for poss ible burned or loose components, loos e connections, or any other obvious condition which might be a source of trouble. An investigation should also be made to ensure that the trouble is not a result of conditions external to the 3300A. 5-53. The checks outlined in this section are not designed to measure all circuit parameters, rather only to localize the malfunction. Ther efore, it is highly probable that additional checks and measurements will be required to completely isolate the faulty component. Amplifier gain may also vary slightly between instruments; therefore, it is not necessary to precisely duplicate waveforms or voltages described.

5-54. MALFUNCTION ISOLATION PLUG. 5-55. A malfunction isolating tool can be fabr icated for

isolating a malfunction to the 3300A or the plug-in unit. A 50 pin connector -hp- Part No. 1251-0099 can be fitted with 4 jumpers (see Figure 5-7 for

limit of the negative slope out of the integrator circuit. The condition of the other major circuits in the basic oscillating loop, the Voltage Comparator Bi-stable Multivibrator and current source, can, in most instances, be used to isolate the malfunction to a given circuit as outlined in Figure 5-8. The term normal, as applied to the results obtained at the different points tested, refers to the output at that point which would reverse the slope at the output of the triangle integrator and sustain oscillation. Abnormal refers to that output which would produce the same slope and prevent oscillation.

5-61. Figure 5-9 contains the normal voltages and waveforms which should be present at the points indicated. Voltage levels are approximate and may vary from instrument to instrument due to differences in transistors.

D-1. General

This appendix provides a summ ary of the maintenance operations for SG-747/U. It authorizes categories of maintenance for specific maintenance functions on repairable items and components an the tools and equipment required to perform each function. This appendix may be used as an aid in planning maintenance operations.

D-2. Maintenance Function.

Maintenance functions will be limited to and define as follows:

a. Inspect.

item by comparing its physical, mechanical, and/or electrical characteristics with established standard through examination.

b. Test.

incipient failure by measuring the mechanical or electrical characteristics of an item and compar ing those characteristics with prescribed standards.

c. Service.

keep an item in proper operating condition, i.e., to clean (decontaminate), to preserve, to drain, to paint, or to replenish fuel, lubricants, hydraulic fluids, or com pres sed air supplies.

d. Adjust

bringing into proper or exact position, or by setting the operating characteristics to the specified parameters.

e. Align.

an item to bring about optimum or desired performance.

f. Calibrate

be made or to be adjusted on instruments or test measuring and diagnostic equipm ents used in precision measurement. Consists of comparisons of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared.

g. Install

into position an item, part, module (component or assembly) in a manner to allow the pr oper functioning of the equipment or system.

like type part, subassembly, or module (component or assembly) for an unserviceable counterpart.

i. Repair.

(inspect, test, service, adjust, align, c alibrate, replace) or other maintenance actions (welding, grinding, riveting, straightening, facing, remachining, or resurfacing) to restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or assembly), end item, or system.

j. Overhaul.

(service/action) necessary to restore an item to a completely serviceable/operational condition as prescribed by maintenance standards (i.e., DMWR) in appropriate technical publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally return an item to like new condition.

k. Rebuild.

necessary for the restoration of unserviceable equipm ent to a like new condition in accordance with original manufacturing standards . Rebuild is the highest degree of materiel maintenance applied to Army equipment. The rebuild operation Includes the act of returning to zero those age measurements (hours, miles, etc.) considered in classifying Army equipments/components.
