INTRODUCTION
1.1 GENERAL
This manual contains theory of operation, maintenance, schematic diagrams and
parts lists for the FM-2748 system (Mainframe with OAM-1 plug-in module) and
plug-in module ODM-1. See Figure 1-1. Difference data, Section II, provides
material to convert the FM-10 Mainframe sections of the manual to the FM-2748
configuration. The OAM-1 and ODM-1 sections of the manual require no difference
data other than their references to the Mainframe: where FM-10 Mainframe is
noted, substitute Mainframe: where FM-10C is noted, ignore.
Refer to Operators Instruction Manual for Model FM-2748/ODM-1, manual
number 500783-250, for complete operating instructions and specifications.

SECTION II
DIFFERENCE DATA
This section contains data defining the differences between the FM-10 Mainframe,
presented in sections III through VI, and the FM-2748 Mainframe. By making the
changes noted in this section, the FM-10 sections may be converted to FM-2748
Mainframe documents.
2.1 THEORY OF OPERATION DIFFERENCES
Page 3-1, paragraph 3.2: Change "loudspeaker, and fixed and variable RF output
attenuators" to read "loudspeaker, and 10 and 1 db step and 0-1 db variable RF
output attenuators,"
Page 3-1, paragraph 3.3: Change "is supplied via variable attenuator AT2 to J2,
the RF output attenuator" to read "is supplied via attenuator АТ! and RF fuse F3
to 72, the RF output attenuator.''
Page 3-1, paragraph 3.4: Change "is amplified by Ql, Q2, and ОЗ" to read "is
amplified by Q2, Q4, Q6, and 08".
Page 3-1, paragraph 3.5: Change "(MEASURE INPUT) to a detector CR2
on assembly Al A4 which acts as a mixer. In CR2, the" to read ' (MEASURE
INPUT) to a doubly balanced mixer ХІ on assembly A1A4. In Xl, the". Change
"switch 511. When 511'' to read "switch 511. In either position of S11, the beat
lamp amplifier consisting of А1 А207 and А1 А209 may be operated. When 511".
Change "at loudspeaker 1,51 and the beat indicator following amplification" to read
"at loudspeaker LS1 following amplification". Change ''511 switches the beat
indicator and loudspeaker circuit'" to read ''511 switches the loudspeaker circuit".
Page 3-9, paragraph 3.18: Add at end of last paragraph of 3.18: "When TIMEBASE
switch А1151 is in the INT position, the 10 MHz signal at terminal А11-36 is
connected to TIMEBASE jack A11J1. When the switch is at EXT, an external
timebase may be supplied to the FM-2748 via TIMEBASE jack А1171."

SECTION III
FM-10 THEORY OF OPERATION
3,1 INTRODUCTION
This section covers the principles of operation of the Mainframe. The
information is presented to assist the user in understanding the circuitry
employed and is also useful in troubleshooting and maintenance of the
equipment. The text is supported by the Typical Frequency Synthesis,
Figure 3-1 and the Overall Functional Diagram, Figure 3-2.
3.2 LEFT HAND MODULE Al
Assembly Al contains the input filter assembly; divider and automatic
level control board A1A2, power supply, AF and IF amplifier board A1A3,
broadband amplifier board AlA4, beat indicator, loudspeaker, and fixed
and variable RF output attenuators.
ЭУ ВЕ ТЕНТ CIRCUIT
Тһе fully synthesized frequency provided Бу the synthesizer section of the
Mainframe is supplied from low-pass filter FL3 on assembly A9 to
broadband amplifier board A1A4 via pin 5. The amplifier output is supplied
via variable attenuator AT2 to J2, the RF output connector.
3.4 BROADBAND AMPLIFIER (A1A4)
Broadband amplifier AlA4 receives the output of the Mainframe fre-
quency synthesizer via pin5. The synthesized frequency is amplified by
Q1, Q2, and Q3 and appears at BNC connector J9.
3,5 MEASURE INPUT CIRCUIT
The input signal is supplied via front panel connector 71 (MEASURE INPUT)
to a detector CR2 on assembly А1А4 which acts as a mixer. In CR2, the

OUTPUT
FREQUENCY
Figure 3-1. Typical Frequency Synthesis
input signal is mixed with the synthesized frequency generated by the
Mainframe supplied from the broadband amplifier. From the mixer, the
output is supplied via pin 7 on AlA4 to IF amplifier Q6 on AlA3. Output
of the mixer may be an audio beat note or the 2-MHz IF signal carrying
modulation which is supplied to the right-hand plug-in module (such as
the MDM-1 or ODM-1) where it is demodulated. The audio output of
A1A3Q6 is supplied to an audio preamplifier consisting of AlA3Q7 and Q8
and then via pin 10 to beat note selector switch 511. When 511 is in the
BEAT (IN) position, the beat note appears at loudspeaker LS1 and the beat
indicator following amplification by operational amplifier U7 on board
AlA2. The output of U7 drives lamp driver Q9. The MOD (OUT) position
of 511 switches the loudspeaker circuit to the demodulated audio output of
any plug-in module which is inserted in the right-hand compartment.
3.6 AUTOMATIC LEVEL-CONTROL
Automatic leveling of the output of the frequency synthesizer portion of the
Mainframe is effected by detector СКІ on AlA4, the automatic level con-
trol amplifier on AlA2, and the gain control amplifier on A7. Detector
СКІ supplies а dc voltage proportional to the amplitude of the output of
broadband amplifier AlA4. The dc output is supplied to ALC amplifier
on AlAZ via pin 15. This de amplifier consists of U5, U6, and O6.
Transistors Q7 and Q8 and the voltage rectifier consisting of CR4 and
CR5 take a 1-MHz signal supplied from Q4 and rectify it to provide
negative dc voltage for use in the ALC circuit. This negative voltage
appears at the junction of AlA2-R39 and AlA2-C27. According to the
level of the synthesized output signal sensed by detector СКІ on assembly
AlA4, the output signal produced by automatic level control amplifier on
AlA2 at pin 15 is a dc voltage proportional to the carrier signal level.
The output signal at pin 15 is routed to a gain control amplifier on assembly
А7 via ріп 1 and rear panel connector J10.
3.7) DIVIDER CIRCUIT (A1A2)
Three standard frequencies (100 kHz, 1 MHz, and 2 MHz) for use in other
sections of the Mainframe are derived by the divider on AlA2 froma
10- MHz input signal (10- MHz No. 2) supplied from pin 24 of rear panel
connector J10. This 10-MHz signal is supplied from the TCXO on All.
NOTE: This 10-MHz signal becomes the 10-MHz No. 3 signal
which appears at pin 3 of AlA2. Тһе 10-MHz No. 3 signal can
be supplied as a substitute input signal to the measure input
circuit for calibration purposes. It is selected by front panel
switch S10.
The 10-MHz No. 2 is amplified by Q1 and Q2 and applied to IC Ul. IC Ul
contains а divide- by- five circuit and а divide-by-two circuit. The 10- MHz
input is applied to the divide-by-five circuit to produce a 2- MHz output.
This output is applied to the divide- by-two circuit and to Q5. The divide-
by-two circuit halves the input to produce a 1- MHz output that is applied
to IC U2 and to O4. The 1- MHz and 2- MHz outputs of IC Ul are buffered
by 04 and Q5 respectively. IC UZ is identical to ІС Ul. : The 1- MHz input
is applied to the divide- by- five circuit, whose output is applied to the
divide-by-two circuit, resulting in a total division of 10. The 100- kHz
output of IG UZ 15 Еее DY OS.
3,8 POWER SUPPLY (CAJAS)
The power supply comprises a 9- volt regulator consisting of Q3, Q4, and
Q5 and а 12- volt regulator consisting of Ol. Transistor Ol mounted on
the rear of the left- hand module for heat sink purposes acts as a series-
pass regulator.
3.9 VOLTAGE- CONTROLLED OSCILLATOR (VCO) BOARD A2
Voltage- controlled oscillator Q10, which provides the 0-1 kHz component
of the final synthesized frequency, is controlled by a dc voltage derived
from variable resistors КІ and R3, which constitute the front panel 0-1
KHz frequency control. Тһе ас voltage varies the capacitance of Varicaps
CRI and ER2 that provide a tuning range of 5 to 6 MHz. Erom Ще oscil-
lator circuit, the output signal is amplified by Q9 and Q8, and the ampli-
fied output signal appears at pin 5. The 5- to 6- MHz output of the VCO
board is switched to the 100 KHz, 10 KHz, or 1 KHz frequency control
when any of these frequency controls are at the V position.
When 0-1 KHz frequency control S7 is at the OUT position, the VCO is out
of the circuit and the 6- MHz signal supplied from pin 9 of А2 is routed to
the 1 KHz, 10 KHz, and 100 KHz frequency controls.
Another function of the VCO is to provide FM modulation. When a plug-in
module that can supply an audio modulating tone is installed, the audio
signal is supplied via pin 6 of A2 to the Varicaps to modulate the 5- to
6- MHz output signal of the VCO. The audio modulating signal at pin 6
comes from the plug-in via left-hand module rear connector 711. Modu-
lation sensitivity is set by R47 and R44.
Also on VCO board A2 are two multiplier circuits that generate standard
frequencies for use in other sections of the instrument.
The circuit consisting of O1, Q2, Q3, and Q4 derives a 9- MHz signal from
the 1- MHz input at pin 3 supplied via rear panel connector P10 from A1A2.
Transistor Ql is a shaper stage, while Q2, Q3, and O4 are amplifiers
tuned to the ninth harmonic of 1 MHz.
The circuit consisting of Q5, Q6, and Q7 derives а 6- MHz signal from the
2- MHz input appearing at pin A2- 8 supplied via rear panel connector P10
from AlA2. Transistor Q5 is a multiplier stage tuned to the third harmonic
of 2 MHz while Q6 and Q7 provide amplification.
5.10 -1- KHz FREQUENCY CONTROL CIRCUIT A3
The 1 kHz frequency control circuit consists of decade divider Ul, sum-
ming mixer 02, difference mixer U3, amplifiers Q1, Q5, and Об, and
buffer stages Q2, 03, and Q4.
The input signal to divider Ul is either the 5- to 6- MHz output of the VCO
circuit on A2 or the 6 MHz output of the X3 multiplier on A2 and is applied
via amplifier Ql. The output of the divider, 0.5 to 0. 6 MHz, is applied to
summing mixer U2. Summing mixer U2 receives a second input of 9 MHz
from A2 via buffer O2. The output of the summing mixer is 9.5 to 9. 6 MHz
and is applied through a bandpass filter to difference mixer U3. Difference
mixer U3 receives a second input of 3.6 to 4.5 MHz from switch 56 via
buffer Q3, and a low pass filter. The 3.6- to 4. 5- MHz signals are received
from frequency generator boards А12 through A21. The output of difference
mixer U3 is 5 to 6 MHz. This output is buffered by Q4 and applied through
bandpass filter FL] to amplifiers Q5 and Q6. The output of the 1 kHz
frequency control circuit varies from 5- to 6-MHz.
3.11 10-kHz FREQUENCY CONTROL CIRCUIT A4
The 10 kHz frequency control circuit is identical to 1 kHz frequency control
circuit A3 except that the output of the 1 kHz frequency control circuit is
one of the inputs to the 10 kHz frequency control circuit. The second and
third inputs of 9 MHz and 3.6 to 4.5 MHz at pins 6 and 8 are also identical.
The output of the 10 kHz frequency control circuit is 5 to 6 MHz.
3.12 100-kHz FREQUENCY“GONTROL CIRCUIT А5
The 100-kHz frequency control circuit is also identical to the 1-kHz and
the 10-kHz frequency control circuits, A3 and A4 respectively, except that
one of its inputs is the output of the 10-kHz frequency control circuit A4.
The output range of the 100-kHz frequency control circuit is 5 to 6 MHz.
3.13 1 MHz FREQUENCY CONTROL CIRCUIT A6
This is a mixer stage with three inputs and one output. The inputs are a
5- to 6-MHz signal at pin 6 from the 100-kHz frequency control circuit,
a 90-MHz signal at pin 4 and a 36- to 45-MHz signal at pin 14. The output
has a range of 50 to 60 MHz.
The 5- to 6-MHz input at pin 6 of A6 is applied to mixer Ul. The other
input to the mixer is the 90-MHz signal. The two inputs are summed,
buffered by Al and amplified by O2, filtered by FL1, mixed with a 36- to
45-MHz input in difference mixer U2, giving an output range of 50- to
60-MHz. This is buffered by Q3, and amplified by Q4 and Q5, filtered by
FL2, and supplied to pin 8 of Aó.
3.14 10-MHz FREQUENCY CONTROL CIRCUIT А8
The 10-MHz frequency control circuit is a mixer stage with three inputs
and one output. The inputs are 70 MHz at pin A8-5, 50 to 60 MHz at
pin A8-3, and 60 to 150 MHz to mixer Z2 located on A8. The output is a
3-6
600- to 700-MHz signal from mixer Z2 that is applied to Gain Control
Amplifier, AT.
The 50- to 60-MHz input at pin A8-3 is derived from 1-MHz frequency
control circuit Ab. This is applied to doubly balanced summing mixer Zl.
The other input to Zl is а 700- MHz signal derived from the 70- MHz input
at pin A8-5. The 70- MHz signal is filtered by the LC network, applied to
harmonic generation diodes CR1 and CR2, and amplified by Q1 which is
tuned to the fifth harmonic. The output of О] is amplified by Q2 and applied
to Q3, which is tuned to the second harmonic of its input, giving an overall
multiplication of 10. Q4 is a buffer amplifier to drive mixer Zl. Thus,
the output of summing mixer Zl is 750 to 760 MHz that is amplified by
Q7 and Q6 and filtered by filter FL1. The output of filter FL1 is applied
to difference mixer Z2 together with the 60- to 150- MHz signal selected
by the 10- MHz frequency control. The output of Z2 is a 600- to 700- MHz
signal varying in 10- MHz steps. This is supplied to the gain control
amplifier located on board A7.
3.15 GAIN CONTROL AMPLIFIER Ат
The input to the gain control amplifier on A7 is derived from the 10- MHz
frequency control on board A8 and consists of a signal in the range of
600 to 700 MHz. The signal is supplied to pin 4 and is amplified by Q8
and Q9, the gains of which are controlled by the signal appearing at pin 1
derived from the automatic level control amplifier on board AlA2. Then,
the signal is applied to diode modulator СКІ and CR2 and passes through
filter FL2 via pin 6. Consisting of CR1 and CR2, the diode modulator
provides amplitude modulation of the signal when a modulating signal is
supplied from a plug-in module via the rear panel connector Jll. From
assembly A7, the output signal is routed to filter Z1 on assembly А9.
3.16 DIODE' SWITCH, MIXER, AND LOW PASS FILTER, A9
The 600 to 700 MHz output signal from filter FL2 on assembly AT is
supplied to doubly balanced difference mixer 21 on assembly A9. Here it
is mixed with а 700 to 1100 MHz signal selected by front panel switch 51
(100 MHz frequency contro1) which operates diode switch circuits consisting
of C R] СЕ MORS СВЕ, за CRS, ТБе application OL FO У dE Vila SWIC
Sl causes one of the diodes to conduct, thus supplying a frequency in the
range of 700- to 1100-MHz to mixer 21. The products of mixing lie in the
range of 0 to 500 MHz, but the output circuit of mixer 21 is limited to the
range of 50 kHz to 500 MHz. The output signal of the mixer is filtered by
low pass filter FL3 and supplied to the broadband output amplifier on assem-
bly AlA4 via connector AlA4-J5.
3.17 100- М BREOUEN CSN CONT ROM CIRCUIT FA TO
Assembly A10 consists of five multiplier-amplifier chains which provide
standard frequencies (700, 800, 900, 1000, and 1100 MHz) to diode switch
circuits on assembly A9.
Input signals to the five chains consist of five frequencies: 70, 80, 90,
100 and 110 MHz. These are also standard frequencies derived from buffer
amplifiers on assembly All.
The 70-MHz input is supplied to pin 1 of A10 and passes through harmonic
generators CR1 and CR2, and then to multiplier Q1 which is tuned to the
fifth harmonic, 350 MHz. The signal is then amplified by buffer amplifier
Q2 and doubled in frequency by multiplier Q3, tuned to 700 MHz. Further
amplification is provided by Q4.
The 80, 90, 100 and 110 MHz signals are all multiplied in identical fashion
in the remaining four chains on assembly A10.
3.18 ТСХО AND BUFFER AMPLIFIER.AI1
The bufferassemblies Gonsist#01. 01.502704, Об; ОТ, and QS: Input
signals to these stages consist of frequencies 70, 80, 90, 100 and 110 MHz.
These are derived from frequency generation assemblies A16 to A20.
Output signals from Q1, Q4, Q6, Q7, and Q8 are supplied to multipliers
on assembly А10. The 70-MHz output of buffer Q2 is supplied to the
10 MHz frequency control on assembly A8.
The other section of assembly All contains subassembly AllAl, the
10-MHz ТСХО crystal that is the prime frequency standard from which
all others in the Mainframe are derived. Transistors Q3 and Q5 provide
two amplified 10-MHz outputs at pins 36 and 39. One output is supplied to
assembly A18 and the other to the left-hand module A1 via rear panel
connector J10.
3.19 FREQUENCY GENERATOR ASSEMBLY (4.5, 45, and 150 MHz) A12
Assembly Al2 generates frequencies of 4.5, 45, and 150 MHz for use in
three separate sections of the Mainframe. There are two standard fre-
quency input signals of 100 kHz and 10 MHz. Output frequencies of 4.5
and 45 MHz are derived by a successive multiplication from the 100-kHz
signal. Тһе 150-MHz output is derived from the 10-MHz input by means
of a X15 multiplier.
The 100-kHz input signal to assembly А12 is generated on assembly AlA2
by divider circuitry. The 100-kHz output of AlA2 is supplied to assemblies
Al2 through A21 by a direct line to assembly A18 and then by crosspatching
to the other assemblies.
The 100-kHz signal is supplied to multiplier Ol, which is tuned to the
forty-fifth harmonic 4.5 MHz. Transistor Q2 and crystal Y2 forma
4,5-MHz filter. Integrated circuit Ul provides amplification and limiting,
and emitter follower Q8 provides isolation. The output of 4.5 MHz
appears at pin 23. А further 4.5- MHz output is taken from Ul at the junc-
tions of pins 11, 12, and 14 and supplied, via crystal Yl, to shaping cir-
cuit Q3 and to multiplier Q4 tuned to the tenth harmonic of 4.5 MHz.
Transistor Q7 is a tuned amplifier. The 45 MHz output appears at pin 20.
The third multiplier on assembly Al2 derives the 150-MHz output from the
10-MHz input appearing at pin 9. The 10- MHz signal is shaped by tran-
sistor Q5 and multiplied by Q6, which is tuned to the fifteenth harmonic
150 MHz. Transistor Q10 and Q11 provide amplification and filtering.

SECTION IV
FM-10 MAINTENANCE
4.1 INTRODUCTION
This section contains general maintenance, troubleshooting, and alignment
information.
NOTE: Throughout EMS Section, the term 'CRT' denotes the
oscilloscope presentation on a plug-in-module. The word
"ОвсіПовсоре! refers to an external test equipment (Tektronix
Model 454 or equivalent).
There are instances in this section where an Oscilloscope with a vertical band-
width greater than 40 MHz is specified. However, the listed Frequency Counter
and RF Voltmeter, used together, may be substituted in some instances. An
example of where the substitution may be made is paragraph 4. 5. 8.b, c, and e.
The listed high impedance probe should be used with the RF Voltmeter for these
readings. However, in paragraph 4.5.8 d, and f, which call for measurements
of the outputs of summing Mixer Ul and difference Mixer U2, both the sum and
difference mixed frequencies are present plus the fundamental frequency. The
presence of these three frequencies will give erroneous readings on the RF Volt-
meter and Frequency Counter.
All DC voltages shown without tolerances on the schematic diagrams in Section V
are typical. These voltages may vary widely (+100%, -50%) from unit to unit due
to component tolerances and wide beta ranges of the transistors. This does not
imply that unit(s), in which measured voltages are at or near the tolerance
extremes will not perform to the specifications, since the unit has been designed
to make allowances for these tolerances.
All AC(including RF) voltages shown without tolerances on the schematic diagrams
in Section V are typical. These voltages may vary widely (+6 dB) from unit to
unit due to component specifications and tolerances, and wide beta ranges of the
transistors. This does not imply that unit(s), in which measured voltages are at
or near the tolerance extremes will not perform to the specifications, since the
unit has been designed to make allowances for these tolerances.
4.2 GENERAL MAINTENANCE INFORMATION
4.2.1 BASIC REQUIREMENTS. Each Mainframe is carefully checked at the
factory and no further internal adjustments are required prior to placing the equip-
ment in operation. In the event of failure or malfunction, troubleshooting or
adjustments should be attempted only if proper test equipment is available and only
by qualified technicians.
4.2.2 TEST EQUIPMENT. The test equipment required for checkout, alignment,
calibration, and troubleshooting is tabulated in Table 4-1. Use the recommended
type or equivalent.
4.3 POWER REQUIREMENTS.
40 VA Maximum for 115/230 Vac operation (without plug-in)
2 A Maximum for 11.5 to 15.0 Vdc operation (without plug-in)

4.5 ALIGNMENT AND ADJUSTMENT
WARNING
High voltages are present throughout the unit, and appropriate
precautions should be taken while operating the unit with the
cover removed.
All circuit boards except AlA2, A1A3, AlA4, A7/A8, and A9/A10 are removed
from their mountings by sliding them out sideways (see Figures 4-1 and 6-1 for
board locations). Most adjustments are made with each board only half-way out
of its compartment. When reinserting boards, dress all wires carefully. Note
that some boards cannot be reinserted unless wires are fully dressed toward
appropriate ends of their compartments.
Adjustments to boards in Left-Hand Module (Al) are made with module partially
withdrawn from Mainframe on extender cable. Adjustments to A7/A8 assembly
are made by removing mounting screws and lifting assembly out. All internal
adjustments described in paragraphs 4.5.1 through 4.5.32 should not be per-
formed until board input levels and +9 V de voltage are verified.
Calibration of the TCXO (paragraph 4.5.33) and adjustment of 0-1 KHz frequency
control may be carried out separately.

Checkout Procedures, Section 4.4, with each subsection keyed to the paragraph
in Section 4.4 that first indicates a fault. When a fault is noted during FM-10
operation, proceed as follows:
a. Perform checkout procedures in Section 4.4.
b. Start fault isolation procedures at the point where minimum performance
cannot be satisfied.
c. When the fault is isolated to a subassembly, suchas gain control amplifier
А7, refer to the alignment procedure for that subassembly in Section 4.5,
and check alignment of subassembly before proceeding with fault isolation.

4.6.6 ALL OUTPUT LEVELS NOT WITHIN TOLERANCE (4.4. 4d, е).
a. Verify that output of broadband amplifier AlA4-9 is -23 dbm +1.5 db.
b. If output of broadband amplifier A1A4-9 is within tolerance, proceed as
follows:
(1) Set RF OUTPUT attenuator at 500 V and set knob to agree with front
panel 500 V line.
(2) Connect Broadband Amplifier (BBA-1) between RF Voltmeter and
Mainframe RF OUTPUT jack.
(3) Note output level and decrease output 20 db by RF OUTPUT
attenuator.
(4) Observe RF Voltmeter and verify that output decreases 20 db +2 db.
(5) If voltmeter indication is not within tolerance, replace variable
attenuator.
(6) If RF OUTPUT attenuator cannot be set at 500 V, check АТІ (10 db
pad) before replacing variable attenuator.
c. If output of broadband amplifier AlA4-9 is not within tolerance, proceed
as follows:
(1). Verity that input of Zi ет RI portis 75 авт *2 db.
(2) If input of Z1 is within tolerance, short terminal AlA2-15 to ground
and verify that output of FL3 is approximately -11 dbm.
(3) If output of F L3 is not within tolerance, check level detector (A1A4)
for approximately -20 dbm #1.5 db at output bandpass filter FL3.
(4) If output is within tolerance, replace broadband amplifier AlA4.
4.6.7 SOME OUTPUT LEVELS NOT WITHIN TOLERANCE (4.4.4d,e). If some
test frequency levels are out of tolerance use Table 5-2 and 5-3 to isolate the
trouble to the particular board assembly causing the trouble.
4.6.8 INSUFFICIENT CARRIER LEVEL CONTROL (4.4.5.1g). Check the level
of the 2 MHz output at AlA3 terminal 7 for 2.5 mV +10%. If not within tolerance,
check board assembly A1A3. If within tolerance, refer to ОАМ-1 instruction
manual to locate the fault.
4.6.9 INSUFFICIENT AM SENSITIVITY (4.4.5.2e). Check input level АТ
terminal 2 for 75 mV +10%. If within tolerance check board assembly А7. If
not within tolerance use ОАМ- 1 instruction manual to locate fault.
4.6.10 EXCESSIVE ANDI ОВО (4.4.5.3c). Check at AT terminal 2 for 1%
maximum distortion. If within tolerance check board assembly А7. If not within
tolerance use ОАМ- 1] instruction manual to locate fault.
4.6.11 INSUFFICIENT FM SENSITIVITY (4.4. 6h). Check at A2 terminal 6 for
500 mV +10% (5 kHz deviation in narrowband position). If within tolerance, check
board assembly А2. If not within tolerance use ODM-] instruction manual to
locate fault.
4.6.12 MEASURE INPUT SENSITIVITY NOT WITHIN TOLERANCE (4.4. 7d).
Check 2 MHz IF output for 2.5 mV +10%. If not within tolerance, check AlA4.
If within tolerance use ODM- 1 instruction manual to locate fault.
4.6.13 OVERLOAD INDICATION NOT WITHIN TOLERANCE (4.4.7e). Check
2 MHz IF output for 25 mV +10%. If not within tolerance, check АТАА. If within
tolerance use ODM- 1 instruction manual to locate fault.
