INTRODUCTION
This section of the manual contains a general descrip­tion of the FG 501A and complete electrical, environmen­tal, and physical specifications. Standard accessories are
also listed. Instrument option information is located in the back of this manual in a separate section.
INSTRUMENT DESCRIPTION
The FG 501A Function Generator provides low distor­tion sine, square, triangle, ramp, and pulse waveforms over the frequency range 0.002 Hz to 2 MHz in eight decade steps. Dc offset up to ±13 V is available. Waveform triggering and gating functions, in addition to being slope (+ or –) selectable, are provided with variable phase control capable of up to ±90° phase shift. The symmetry of the output waveform may also be varied from 5 to 95%. Step attenuators provide up to 60 dB of attenuation in 20 dB steps. A variable amplitude control provides an additional 20 dB attenuation.
A voltage-controlled frequency (VCF) input is provided to control the output frequency from an external voltage source. The output frequency can be swept above and below the selected frequency to a maximum of 1000:1 depending on the polarity and amplitude of the VCF input signal and the selected output frequency.

OPERATING INSTRUCTIONS
INTRODUCTION
This section of the manual provides operating informa­tion required to obtain the most effective performance from the FG 501A. Included are installation and removal instructions, a functional description of the front panel controls, and a general description of the operating modes. Some basic applications of the instrument are also briefly discussed.
INSTALLATION AND REMOVAL
The FG 501A is calibrated and ready to use when received. It operates in one compartment of any TM 500­series power module. Refer to the power module instruc-
tion manual for line voltage requirements and power
module operation.
CAUTION
To prevent damage to the FG 501A, turn the power module off before installation or removal of the instrument from the mainframe. Do not use ex­cessive force to install or remove.
showing: owner (with address) and the name of an individual at your firm that can be contacted. Include complete instrument serial number and a description of the service required.
If the original package is not fit for use or not available,
repackage the instrument as follows:
Surround the instrument with polyethylene sheeting, or other suitable material, to protect the exterior finish. Obtain a carton of corrugated cardboard of adequate strength and having inside dimensions no less than six inches more than the instrument dimensions. Cushion
the instrument by tightly packing dunnage or urethane foam between the carton and the instrument, on all sides. Seal the carton with shipping tape or an in­dustrial stapler.
The carton test strength for your instrument is 200
pounds.
Check to see that the plastic barriers on the inter­connecting jack of the selected power module compart­ment match the cutouts in the FG 501 A circuit board edge connector. If they do not match, do not insert the instrument until the reason is found. When the units are properly matched, align the FG 501A chassis with the upper and lower guides of the selected compartment (see Fig. 2-1). Insert the FG 501A into the compartment and press firmly to seat the circuit board edge connector in the power module interconnecting jack. Apply power to the FG 501A by operating the power switch on the power module.
To remove the FG 501A from the power module, pull
the release latch (located in the lower left corner) until the
interconnecting jack disengages. The FG 501A will now slide straight out.
REPACKAGING FOR SHIPMENT

OPERATING CONSIDERATIONS
OUTPUT CONNECTIONS
The output of the FG 501A is designed to operate as a
50
fl
voltage source working into a 50 Q load. At higher frequencies, an unterminated or improperly terminated output will cause aberrations on the output waveform.
Loads less than 50
Excessive distortion or aberrations, due to improper termination, are less noticeable at the lower frequencies (especially with sine and square waveforms). To ensure waveform purity, observe the following precautions:
1. Use good quality 50
tors.
2. Make all connections tight and as short as possible.
3. Use good quality attenuators if it is necessary to
reduce waveform amplitude applied to sensitive circuits.
4. Use terminations orimpedance matching devices to
avoid reflections when using long cables (6 feet or more).

If there is a dc voltage across the output load, use a coupling capacitor in series with the load. The time constant of the coupling capacitor and load must be long enough to maintain pulse flatness.
RISETIME AND FALLTIME
If the FG 501A is used to measure the rise or falltime of a device, the riestime characteristics of associated equip­ment should be considered. If the risetime of the device under test is at least 10 times greater than the combined risetimes of the FG 501A and associated equipment, the error introduced will not exceed ignored. When the rise or falltime of the test device is less than 10 times as long as the combined risetimes of the testing system, the actual risetime of the system must be calculated. The risetime of the device under test can be determined once the risetime of the system is known.

With the FG 501A set for free-running operation, as described in previous paragraphs, apply the triggering or gating signal to the TRIG/GATE IN connector.
If only one cycle of the output waveform per trigger is desired, push the TRIG button and select + or – slope. One output cycle will now be generated for each input trigger cycle.
In triggered or gated operation the PHASE control
varies the start of the output waveform by ±90°. This
phase change is measured from the 0 V, 0° point on the
output waveform.
VOLTAGE CONTROLLED FREQUENCY
(VCF) OPERATION
The output frequency of any selected waveform can be swept within a range of 1000:1 by applying an external voltage to the VCF INPUT connector. The polarity of the VCF input signal determines which direction the output frequency sweeps from the selected frequency, A positive
(+) going signal increases the frequency while a negative (–) going signal decreases the frequency. The amplitude
and polarity of the input voltage can be selected within a range of ±10 V depending on the FREQUENCY Hz dial
setting.
The maximum swept frequency range of 1000:1 encom-
passes the uncalibrated portion of the FREQUENCY Hz dial (<.2 to 2). To ensure that the frequency does sweep at least a range of 1000:1, it is recommended that the
FREQUENCY Hz dial be set at .2 and a 0 to +10 V signal be
applied to the VCF INPUT connector. It may be necessary

to vary the FREQUENCY VERNIER control to obtain the full 1000:1 swept range or the lowest swept frequency

Since the VCF input amplitude is a linear relationship, the frequency output range can be determined from the pulse is generated for each negative cycle of the output VCF input amplitude.
A +4 V square wave is available from the TRIG OUTPUT connector. The frequency of the trigger output is determined by the frequency of the selected output

LOOP
FREQUENCY CONTROL AND SUMMING
AMPLIFIER
The voltage developed across the frequency control divider string, R1429, R1321, R500 and R510, is applied to pin 5 of operational amplifier U1540B. This voltage is
buffered by the amplifier and. a current is developed
through R1551. This current is applied top in 2 of summing
amplifier U1540A where it is summed with any currents developed by a voltage applied tothe VCF inputs. The VCF inputs are J510 (front panel) through R1553, and pin 21B (rear interface) through R1103. These summed currents are buffered by Q1445 and flow through R1543. The voltage developed across R1543 is proportional to the
frequency.
CURRENT SOURCES AND SWITCH
The voltage developed across R1543 is buffered by
U1440 and Q1541 which form the negative current source
for the main Ioop timing circuitry. This same voltage is also
buffered by U1540C and Q1543 which form a current source identical to U1440 and Q1541. The output current
from Q1543 flows through Q1527, Q1525, and Q1421,
which form a current mirror that inverts this current to provide the positive current source for the main loop
timing circuitry. The current through R1521 is the timing
capacitor charging current; the current through R1536 is
the discharging current. The Top Dial Symmetry Cal,
R1421, adjusts the balance between these two currents so
they are equal in magnitude.

These currents are switched into the junction of CR1531 and CR1533 where they alternately charge and discharge the timing capacitor, producing a triangle waveform, The current switch is formed by Q1531, CR1531, Q1433 and CR1533.

LEVEL COMPARATORS
The level comparators detect upper and lower
threshold levels. U1700A is the upper level detector and
U1700B the lower. The reference level for these com­parators is supplied by U1400B and C. As the threshold levels are detected, the respective comparator triggers U1600B.
REFERENCE VOLTAGES
The reference voltage supplies are composed of U1400B (–) and U1400C (+) and associated components. The upper (positive) level threshold voltage is established by adjusting R1412. This resistor is in a voltage divider string from zener diode VR1413. The voltage developed across R1412 is buffered by U1400C and set to ap­proximately +400 mV at the output. This voltage is applied to pin 5 of U1700A as the upper threshold level reference. This same voltage is also applied to pin 9 of inverter
U1400B. R1511 is used to adjust the gain of this stage so that the output is nominally –400 mV. This voltage is applied to pin 13 of U1700B as the lower threshold level reference.
LOOP LOGIC
When a rising voltage at pin 6 of U1700A passes through the threshold level set at pin 5, the output (pin 8) goes low pulling pin 10 of U1600Blow. This action sets the flip-flop causing pin 9 (Q) to go high and pin 8 (Q) to go low. Pin 8 of U1600B is tied back, through R1403, to the junction of CR1431 and VR1532. VR1532 serves as a level shifter to change the TTL output gate to the correct level to drive the current switch (Q1531, CR1531, Q1433,
CR1533).
As the voltage at the junction of R1532 and R1534 drops, it pulls the bases of Q1531 and Q1433 low. Q1531 is turned on and Q1433 is turned off. Any current from the
positive current source, through R1521, now flows through Q1531 and is shunted to the –15 V supply. With Q1433 turned off, any current flow through the negative current source must come from the positively charged timing capacitor through CR1533.
The falling voltage on the timing capacitor is buffered
through the triangle buffer and applied to the level
comparators U1700A and U1700B. As the voltage at pin 12
of U1700B falls through the threshold level set at pin 13, the output (pin 1) goes low pulling pin 13 of U1600Blow.
This action resets the flip-flop causing pin 9
(Q) tonowgo
The action just described generates one entire cycle of
a triangle wave.
TRIGGER GENERATOR
The square wave output at pin 8 drives the trigger output amplifier. This circuit is com­posed of emitter follower Q1431 and associated com­ponents. Q1440, in conjunction with R1440, serves as output short circuit protection. The output of this circuit (at J2043) is a square wave 180° out of phase with the main loop signal. The output amplitude is greater than +4 V into an open circuit, and at least +2 V into a 50

load.
SQUARE WAVE GENERATOR
The output at pin 9 (Q) of U1600B is a square wave, but
180° out of phase with that at pin 8. This signal is used to drive the square wave generator composed of differential pair Q1801, Q1901, and associated components. The base of Q1901 is held at a constant voltage by divider network
R1815 and R1818. R1728 and R1816 form a constant current source for the differential pair. The square wave from U1600B alternately switches this constant current to ground through Q1801 or through R1819 and Q1901. In this manner, a square wave voltage is developed with dc levels sufficient to drive the output amplifier for the square wave function.
PHASE CLAMP THRESHOLD DETECTOR
The output of the triangle buffer, in addition to possibly
being fed to the Output Amplifier through S1901B, is connected to the base of Q1711. Q1711 and Q1611 form a differential amplifier. Q1621 and associated components
provide a constant current source for the differential pair. This amplifier senses the level of the triangle waveform and compares it to the output voltage of U1400A. The output voltage of U1400A is determined by the setting of the VAR 0 control, R550. The voltage range of R550 is established by reference voltage supplies U1400B (–) and
U1400C (+). These are the same reference voltages supplied to the Level Comparators. This arrangement
permits comparison of the triangle voltage with the
maximum possible positive and negative levels, and all
levels between.
When the triangle voltage exceeds the reference voltage set by the VAR 0 control, Q1711 turns off. Any current flowing through Q1621 now flows through Q1611.

TM 9-6625-474-14&P-2
CURRENT AMPLIFIER
Current flowing through Q1611 also flows through R1622 and is amplified by Q1521. Temperature compen­sation for this amplifier is provided by CR1621. Differential pair Q1511 and Q1523 serve as a current switch. With Q1511 turned off, any current amplified by Q1521 passes through Q1523 to the junction of CR1531 and CR1533. When the timing capacitor voltage rises to the threshold
TRIG/GATE AMP AND SINE SHAPER
TRIG/GATE AMP AND LOGIC
The input trigger amplifier consists of an emitter coupled differential pair (Q1320 and Q1322), current amplifier Q1324, and the required logic circuitry to control
the operation of the main loop phase clamp. Input circuit
protection is provided by R1203, R1204, CR1220 and CR1221. Triggering signals are applied either through
front panel connector J520 or interface connections on the rear edge of the Main circuit board.
The differential pair, Q1320-Q1322, responds to the
input signal when the voltage rises above (+ SLOPE) the reference voltage at the base of Q1320. This reference voltage is established by divider network R1312 and
R1314, The position of S1400D, SLOPE switch, deter­mines whether a positive or negative going input will
cause the amplifier Q1324 to conduct. When the threshold level is exceeded and conduction starts, current flow through the circuit causes a voltage to be developed across R1322. This voltage is applied to the base of Q1324. The output at the collector of Q1324 is a TTL compatible waveform to drive the logic circuit, U1310. CR1320
provides temperature compensation for Q1324.
level set by the VAR 0 control, R550, it is clamped. Q1523 now draws exactly the amount of current that the positive current source supplies. Because the square wave at pin 5 (Q) of U1600A drives the base of Q1511, the clamping action only happens during the positive edge of the
triangle wave. On the negative transition, Q1523 is shut
off, and Q1511 is on. In this manner, the timing capacitor voltage can be clamped at any desired positive level.
@
as long as this condition exists. As soon as the level at the
input connector drops below the threshold, the output voltage of U1310A rises. This high level causes the generator to again stop running when the phase clamp reaches its threshold level at the end of the last complete cycle.
In the FREE RUN mode, S1400A is positioned such that pin 4 of U1600A is held low. The generator now outputs continuous waveforms.
SINE SHAPER
The Sine Shaper is composed of three separate circuit
functions: a Transconductance Amplifier, the Shaper
Circuitry, and an Output Buffer.
Transconductance Amplifier. Emitter coupled tran-
sistors Q1210 and Q1212 along with current source Q1200
form the Transconductance Amplifier. The amplifier con-
verts the triangle voltage at the base of Q1212 to a differential current. This current flows through two sets of diode wired transistors, U1120C, U1120D, U1220C, and U1220D, to the input of the shaper.
Three modes of operation are selectable with S1400;
Triggered, Gated, and Free Running.
In the TRIG mode, S1400A and S1400C are positioned such that the output, pin 6, of U1310B is connected to pin 4, set input, of U1600A. In this mode, a very narrow,
negative going voltage pulse is developed by U1310B each time the input waveform passes through the trigger threshold. This low sets U1600A, which deactivates the
phase clamp until the triangle generator again starts in the
positive direction, and allows the generator to complete one full cycle.
In the GATE mode, S1400A and S1400C are positioned such that the output, pin 3, of U1310A is connected to pin 4, set input, of U1600A. In this mode, a low level is
produced whenever the input waveform exceeds the
threshold if + SLOPE is selected. The generator free runs
Shaper. The active portion of the Shaper is formed by
two sets of emitter coupled transistors U1220A, U1220B,
U1120A and U1120B. These devices have their inputs
wired in series and their outputs cross coupled. U1120E
and U1220E are current sources for these devices. The
circuit operates by generating a power series approxima­tion to the sine function. The devices in U1120 generate the first order term while those in U1220 generate the second order term in the approximation.
Output Buffer. The Output Buffer is an operational amplifier that converts the differential current from Q1010 and U1020D to a single ended voltage that is applied,
through the function switch, to the output amplifier.
U1020E is a current source for the emitter coupled differential input pair U1020A and U1020B. Q1012 serves as a current mirror for U1020A and as an active load for U1020B. U1020C is the output emitter follower and R1020 is the feedback resistor.
3-3
TM 9-6625-474-14&P-2
OUTPUT AMPLIFIER & ATTENUATORS
The output amplifier is basically a noninverting
operational amplifier whose plus input is the base of
Q2101 and minus input is the base of Q2113.
The three basic waveforms are selected by S1901 and applied across R560B and R2335 to the input stage of the amplifier. R560B varies the amplitude of the selected waveform. The feedback network consists of R2011 and
R2012, connected from the output to the minus input of the amplifier. C2011 provides high frequency compensa­tion for the feedback, and is used to adjust the squarewave front corner. The input pair, Q2101 and Q2113, amplify the
difference between the input waveform and the fedback
waveform.
An offset current is also summed with the feedback signal at the base of Q2113 when S510A is closed. This allows R560A to control the dc offset of the output signal.
POWER SUPPLY
The FG 501A receives its power from the power module via interface connections on the rear edge of the Main circuit board. The power module supplies plus (+) and minus (–) 33.5 Vdc (unregulated) from which the follow­ing regulated voltages are generated.
+20 V SUPPLY
The +33.5 V from the power module is filtered and applied to voltage regulator U1210 (pins 11 and 12). This regulator contains its own reference, operational
amplifier, and current Iimiting elements. The output of the regulator is applied to Q1231 which serves as a driver the
the series pass transistor located in the power module.
The +20 V output is applied across voltage divider R1201, R1301, and R1315. The output level of the supply is set by R1301 (+15 V Adj) which compares the supply output to
the internal reference level of the regulator. This supply is
current limited through the action of R1121 and the current limiting element in the regulator. When excessive amounts of current are drawn from the supply, the voltage developed across R1121 turns on the current limiting element in the regulator (U1210). This action reduces the base drive, through Q1231, to the series pass transistor causing the supply to reduce output, This supply is the reference for other supplies in the FG 501A.
@
The output of Q2101 is applied directly to Q2111 which
is cascoded with Q2011. The output of Q2113 passes
through an inverting amplifier, Q2211, before passing to
Q2213 cascoded with Q2311. CR2111 provides tem­perature compensation for Q2211. The two cascodes form drivers for the amplifier output stage.
The output stage consists of Q2013 and Q2123 in parallel with Q2121 for amplification of positive going signals. Q2321 and Q2323 in parallel with Q2325 form the amplifier for negative going signals. The output is taken at the junction of R2026 and R2228. The 50 impedance is determined by parallel 100
R2033 and R2131. C2121 in this network provides high frequency compensation for the output impedance, The attenuator circuit is a constant impedance resistive divider
network, switch selectable in 20 dB steps.

+20 V supply. Since this supply is sourced from the +20 V, it is inherently current limited by the +20 V supply.
+5 V SUPPLY
The +5 V supply consists of U1230C and Q1331. U1230C serves as an error amplifier which compares the +5 V output to a +5 V reference developed by divider network R1231, R1232 and R1233 from the +20 V supply. Since this supply is sourced from the +15 V and referenced
to the +20 V supply, it is inherently current limited under the same conditions that limit those supplies.
–20 V SUPPLY
The –20 V supply is derived from –33.5 V supplied by
the power module. The output of operational amplifier
U1230A is applied, through Q1245, to the base of Q1241,
which serves as a driver for the series pass transistor located in the power module. This supply is also referenc­ed to the +20 V. The supply is current limited through the
action of R1141 and Q1243. When excessive amounts of current are drawn through R1141, a voltage sufficient to
turn Q1243 on develops across R1141. This action reduces the base drive to the series pass transistor causing the supply to reduce output.
–15 V SUPPLY
+15 V SUPPLY
The +15 V supply consists of U1230D and Q1221.
U1230D serves as an error amplifier which compares the

The –15 V supply consists of operational amplifier (U1230B) and a series pass feedback regulator (Q1345), The output of the supply is fed back through divider network R1247, R1341, and R1245. The output level is adjusted by R1341. Because this supply is sourced from
the –20 V supply, it is current limited by the –20 V supply.

OBTAINING REPLACEMENT PARTS
Electrical and mechanical parts can be obtained through your local Tektronix Field Office or represen­tative. However, it may be possible to obtain many of the standard electronic components from a local commercial source. Before purchasing or ordering a part from a source other than Tektronix, Inc., check the Replaceable
Electrical Parts list for the proper value, rating, tolerance,
and description.
SOLDERING TECHNIQUES
WARNING
To avoid electric-shock hazard, disconnect the
instrument from the power source before soldering.
The reliability and accuracy of this instrument can be maintained only if proper soldering techniques are used when repairing or replacing parts. General soldering techniques which apply to maintenance of any precision electronic equipment should be used when working on this instrument. Use only 60/40 rosin-core electronic grade solder. The choice of soldering iron is determined
by the reapir to be made.
When soldering on circuit boards or small wiring, use only a 15 watt, pencil type soldering iron. A higher wattage soldering iron can cause the etched circuit wiring to separate from the board base material and melt the insulation from small wiring. Always keep the soldering iron tip properly tinned to ensure the best heat transfer to the solder joint. Apply only enough heat to remove the component or to make a good solder joint. To protect heat sensitive components, hold the component lead with a
pair of long-nose pliers between the component body and
the solder joint. Use a solder removing wick to remove
excess solder from connections or to clean circuit board pads.
NOTE
When selecting replacement parts, remember that the physical size and shape of a component may affect its performance in the instrument.
Some parts are manufactured or selected by Tektronix,
Inc., to satisfy particular requirements or are manufac-
tured for Tektronix, Inc., to our specifications. Most of the
mechanical parts used in this instrument have been
manufactured by Tektronix, Inc. To determine the
manufacturer, refer to the Replaceable Parts list and the Cross Reference index, Mfr. Code Number to Manufac-
turer.
When ordering replacement parts from Tektronix, Inc.,
include the following information:

SEMICONDUCTORS
To remove in-line integrated circuits use an extracting
tool. This tool is available from Tektronix, Inc.; order
Tektronix Part Number 003-0619-00. If an extracting tool is not available, use care to avoid damaging the pins. Pull slowly and evenly on both ends of the integrated circuit. Try to avoid disengaging one end before the other end.
INTERCONNECTING PINS
Several methods of interconnection including multi pin and coaxial cable, are used to electrically connect the circuit boards with other boards and components.
COAXIAL CABLES
Replacement of coaxial end lead connectors requires
special tools. Damaged cables should be replaced as a
unit. For cable part numbers see the Replaceable Mechanical Parts list. Fig, 5-1 shows a coaxial connector assembly.

DIAGRAMS AND CIRCUIT BOARD ILLUSTRATIONS
Symbols
Graphic symbols and class designation letters are
based on ANSI Standard Y32.2-1975.
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 manufac­turer’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 Y1.1-1972.
Other ANSI standards that are used in the preparation
of diagrams by Tektronix, Inc. are:

Component Values
Electrical components shown on the diagrams are in
the following units unless noted otherwise:
Capacitors = Values one or greater are in picofarads (pF).
Values less than one are in microfarads
Resistors = Ohms
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 illustration. The Replaceable Electrical Parts list is arranged by assemblies in numerical sequence; the components are listed by component
constructing a component number).
number *(see following illustration for
The schematic diagram and circuit board component location illustration have grids. A lookup table with the grid coordinates is provided for ease of locating the component. Only the components illustrated on the facing diagram are listed in the lookup table. When more than one schematic diagram is used to illustrate the circuitry on a circuit board, the circuit board illustration may only appear opposite the first diagram on which it was il­lustrated; the lookup table will list the diagram number of other diagrams that the circuitry of the circuit board appears on.

MAINTENANCE ALLOCATION CHART
Section 1. INTRODUCTION
B-1. GENERAL.
a. This section provides a generaI explanation of all maintenance and repair functions authorized at various
maintenance categories.
b. The Maintenance Allocation Chart (MAC) in Section II designates overall authority and responsibility for the performance of maintenance functions on the identified end items or component. The application of the maintenance functions to the end item or component will be consistent with the capacities and capabilities of the designated maintenance categories.
c. Section III lists the tools and test equipment (both special and common) required for each maintenance function as referenced from Section II.
d. Section IV contains supplemental instructions and explanatory notes for a particular maintenance function.
B-2. MAINTENANCE FUNCTIONS. Maintenance Functions will be limited to and defined as follows:
a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical characteristics with established standards through examination (e.g., by sight, sound, or feel).
b. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, electrical characteristics of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean
(includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical
fluids, or gases.
d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper or exact position, or by setting the operating characteristics to specified parameters.
e. Aline. To adjust specified variable elements of an item to bring about optimum or desired performance.
f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test, measuring, and diagnostic equipment 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. Removal/Install. To remove and install the same item when required to perform service or other maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in a manner to allow the proper functioning of an equipment or system.
h. Replace. To remove an unserviceable item and install a serviceable counterpart in its place. i. Repair. The application of maintenance services 1, including fault location/troubleshooting 2, removal/
installation, and disassembly/assembly 3, procedures, and maintenance actions 4, to identify troubles and 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.
B-1
TM 9-6625-474-14&P-2
j. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely serviceable-operational condition as required by maintenance standard 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. Consists of those services/actions necessary for the restoration of unserviceable equipment to a
like-new condition in accordance with original manufacturing standards. Rebuild is the highest degree of material
maintenance applied to army equipment and is normally reserved for the depot category of maintenance. The
rebuild operation includes the act of returning to zero those age measurements (hours/mile, etc. ) considered in
classifying army equipment/components.
(1) Services - inspect, test, service, adjust, aline, calibrate, and/or replace. (2) Fault locate/troubleshoot - the process of investigating and detecting the cause of equipment
malfunctioning; the act of isolating a fault within a system or Unit Under Test (UUT).
(3) Disassembly/assembly - encompasses the step-by-step taking apart (or breakdown) of a repairable assembly (group numbered item) to the level of its least componency identified as maintenance significant (i.e., assigned an SMR code) for the category of maintenance under consideration.
(4) Actions - welding, griding, riveting, straightening, facing, remachinery, and/or resurfacing.
B-3. EXPLANATION OF COLUMNS IN THE MAC, SECTION II.
a. Column 1, Group Number. Column 1 lists group numbers, the purpose of which is to identify maintenance
significant components, assemblies, subassemblies, and modules with the next higher assembly.
b. Column 2, Component/Assembly. Column 2 contains the names of components, assemblies, subassemb-
lies, and modules for which maintenance is authorized.
c. Column 3, Maintenance Function. Column 3 lists the functions to be performed on the item listed in
Column 2 (for detailed explanation of these functions, see paragraph B-2).
d. Column 4, Maintenance Category. Column 4 specifies, by the listing of a work time figure in the
appropriate subcolumn(s), the category of maintenance authorized to perform the function listed in Column 3.
This figure represents the active time required to perform that maintenance function at the indicated category of
maintenance. If the number of complexity of the tasks within the listed maintenance function vary at different maintenance categories, appropriate work time figures will be shown for each category. The work time figure represents the average time required to restore an item (assembly, subassembly, component, module, end item, or system) to a serviceable condition under typical field operating conditions. This time includes preparation time (including any necessary disassembly/assembly time), troubleshooting/fault location time, and quality assurance/
quality control time in addition to the time required to perform the specific tasks identified for the maintenance functions authorized in the maintenance allocation chart. The symbol designations for the various maintenance categories are as follows:
C O F H L
Specialized Repair Activity (SRA)
Organizational Maintenance
Direct Support Maintenance
General Support Maintenance
D
This maintenance category is not included in Section II, column (4) of the Maintenance Allocation Chart. To identify functions
5
to this category of maintenance, enter a work time figure in the “H” column of Section II, column (4), and use an associated reference code in the Remarks column (6). Key the code to Section IV, Remarks, and explain the SRA complete repair
application there. The explanatory remark(s) shall reference the specific Repair Parts and Special Tools LIST (RPSTL) TM which contains additional SRA criteria and the authorized spare/repair parts.
