PREFACE
SCOPE
This manual contains instructions for operating the FM/AM-1200S/A
Communications Service Monitor. The instruction level of this manual is
relatively basic and presupposes no previous experience on the part of
the operator with a communication service monitor of this type. A basic
understanding, however, of communication electronics and practical
troubleshooting methods will be helpful. It is strongly recommended
that operator be thoroughly familiar with Sections 1 through 3 of this
manual before attempting to perform any operating procedures contained
in Section 4.
APPLICABILITY
All information contained in this manual applies to both the FM/AM-1200S
and FM/AM-1200A models, except where otherwise noted. For reasons of
brevity, whenever text information is applicable to both models, the
units are referenced as "FM/AM-1200S/A" (instead of FM/AM-1200S and
FM/AM-1200A separately).
ORGANIZATION
The operation manual is divided into the following major sections:
SECTION 1 - INTRODUCTION
Provides a brief introduction to the FM/AM-1200S/A including pur-
pose, functional capabilities and uses.
SECTION 2 - INSTALLATION
Provides a step-by-step procedure for setting up the FM/AM-
1200S/A for operation.
SECTION 3 - DESCRIPTION OF CONTROLS, CONNECTORS & INDICATORS
Identifies and functionally describes all FM/AM-1200S/A controls,
connectors and indicators.
\NOTE}
As an operating aid, Figure 3-1 (which locates
and identifies all FM/AM-1200S/A front panel
controls) has been incorporated into a fold-out
page. By extending the fold-out page, the
operator can easily reference any front panel
control while simultaneously performing any
operating procedure contained elsewhere in this
manual.
SECTION 4 - OPERATION
Contains instructions for operating the FM/AM-1200S/A Keyboard
and VFD.» Using the Keyboard, the operator can enter data into
the FM/AM-1200S/A in the following modes:
1... Directs Data. Entry
2. Programmed Data Entry into Memory
3. Executed Data Entry from Memory
In addition to Keyboard operation, this section contains a selection of
basic operating procedures pertaining to all major functions of the
FM/AM-1200S/A.
SECTION 5_- AVAILABLE OPTIONS
Contains descriptions and operating procedures of available
options to the FM/AM-1200S/A.
Useful supplementary information relating to the operation of the
FM/AM-1200S/A is contained in appendices at the rear of the manual.

SECTION 1 - INTRODUCTION
1 GENERAL
The FM/AM-1200S/A is a microprocessor controlled, digitally synthesized
communication service monitor, which integrates the functions of several
different test instruments into a single, compact and portable unit.
Utilizing such features as a keyboard entry system, a Vacuum Fluorescent
Display for digital readout, processor controlled memory functions, a
CRT capable of displaying oscilloscope inputs and a DTMF encoder used
simultaneously with the variable audio generator for audio tone
encoding, the FM/AM-1200S/A incorporates the functions of the following
test equipment:
Signal Generator Frequency Error Meter
Communication Receiver Modulation Meter
Digital Voltmeter (Option) SINAD Meter
Oscilloscope Audio Error Meter
1 kHz (Fixed) Tone Generator Signal Strength Meter
Variable Tone Generator DUPLEX Generator (with
(Programmable) a selectable offset)
DTMF Encoder Spectrum Analyzer
DTMF Decoder (Option) (FM/AM-1200S only)
Power Meter Tracking Generator (Option,
FM/AM-1200S only)
These capabilities enable the FM/AM-1200S/A to be used in a wide range
of communication test functions associated with most types of simplex
and duplex transceiving equipment, including mobile telephone systems,
AM/FM/SSB transceivers, CB and two-way radio systems, repeaters, etc.
1-2 SIGNAL GENERATOR/RECEIVER
The FM/AM-1200S/A Signal Generator is capable of generating modulated or
unmodulated carrier signals within a range of 250 kHz to 999.9999 MHz
(in 100 Hz steps), at an output level which is continuously variable
from -20 to -127 dBm. The generated carrier signal may be AM or FM
modulated by internal modulation signals from the FM/AM-1200S/A tone
generators or by external sources applied through front panel modulation
input connectors defined in Section 3 of this manual. The signal
generator may also be voice-modulated and keyed through the front panel
microphone input connector. All of the above described modulation
sources, or any combination thereof, may be simultaneously applied to
the carrier signal. During signal generator operation, signals being
generated can be monitored by the FM/AM-1200S/A receiver and its
associated monitoring devices.
The signal generator also features a selectable offset frequency func-
tion to permit testing of duplex equipment, which receives and transmits
simultaneously on different frequencies. See paragraph 1-3 for addi-
tional information about this feature.
The FM/AM-1200S/A receiver is a triple conversion, superheterodyne
receiver, capable of monitoring communication signals within a range of g
250 kHz to 999.9999 MHz, in 100 Hz steps. Signals may be received e,
"off-the-air" using an external antenna or by direct cable connection
through the front panel T/R Connector. Associated receiver monitoring
circuits include a frequency error meter, modulation meter, power meter,
SINAD meter, signal strength meter, frequency error and demodulated
audio counters, oscilloscope and spectrum analyzer (FM/AM-1200S only).
1-3 FM/AM-1200S/A CAPABILITIES
A prime feature of the FM/AM-1200S/A is the capability of testing both
Simplex and duplex communication equipment. Simplex operation is
defined as any equipment that communicates in only one direction at a
time on the same frequency, including ordinary transmit-receive or
press-to-talk operation, voice operated carrier and other forms of
manual or automatic switching from transmit to receive. Duplex opera-
tion is characteristic of any equipment which transmits on one frequency
and receives on another frequency between two locations, such as mobile
telephone systems and repeaters.
In receive mode, the FM/AM-1200S/A receiver monitors incoming signals
received "“off-the-air" or applied via direct cable connection through
the front panel T/R Connector. In this mode, the FM/AM-1200S/A signal
generator is inactive. In the generate mode, the FM/AM-1200S/A is
capable of generating modulated or unmodulated carrier signals while the \
receiver circuits are simultaneously monitoring the generator. \=
In the duplex mode, the FM/AM-1200S/A has the capability of generating
and receiving signals simultaneously. While the receiver section of the
FM/AM-1200S/A is monitoring incoming signals transmitted by the UUT, the
FM/AM-1200S/A duplex generator is simultaneously generating signals to
Stimulate the receiver section of the UUT. The frequency of the
generated signal from the FM/AM-1200S/A can be offset up to +49.99 MHz
from the receiving frequency in 10 kHz steps. Three methods of duplex
testing are available using the FM/AM-1200S/A. They are:
Duplex Testing using separate Transmit/Receive Lines
Duplex Testing using one common Transmit/Receive Line
"Off-the-air" Duplex testing
The methods of duplex testing are described in detail in Section 4.
1-4 DATA DISPLAY AND CONTROL FEATURES
Operator interaction with the FM/AM-1200S/A is facilitated through the
following primary data display and control features:
A. KEYBOARD
The Keyboard provides a means of entering data into the FM/AM-
1200S/A microprocessor, to control the operation of the RF Fre-
quency or Tone Generator functions. The Keyboard is also used to
address the FM/AM-1200S/A programmable functions which utilize the
automatic storage, retrieval and execution capabilities of the set.
All Keyboard functions are described in detail in Section 3.
B. VFD
The Vacuum Fluorescent Display (VFD) is used to display the current
Keyboard operating frequencies associated with the FM/AM-1200S/A
tone generator or RF Frequency functions. The VFD will display any
telephone number selected during DTMF or IMTS functions (Ref. Sec
tion 3), provide a digital readout of the selected range of both
the FREQ ERROR and MODULATION Meters or display Digital Voltmeter
readings.
1-5 GENERATOR/RECEIVER SUPPORT FUNCTIONS
The FM/AM-1200S/A has the following additional operating functions which
are primarily used to support the generate/receive capabilities of the
seu:
Digital Voltmeter (Option) Fixed Tone Generator
Oscilloscope Programmable Tone Generator
Modulation Meters Freq Error Meter
Spectrum Analyzer (FM/AM-1200S Only)
The application and use of these functions are described in detail in
Sections 3 and 4.
1-6 AVAILABLE OPTIONS
In addition to the standard features of the FM/AM-1200S/A, several
optional features are available. These include:
.05 PPM Frequency Standard European Signaling

INTERNAL Battery Operation:
Li Place PWR/OFF/BATT Switch to "BATT" position. (This is a
Spring-Loaded ON/OFF Switch.) When operating the test set on
battery, an internal timer will interrupt power after
approximately 10 minutes. Depress PWR/OFF/BATT Switch to "BATT"
position to restore power to test set.
\NOTE}
The internal battery is charged whenever the test set
is connected to external AC or DC power, regardless of
whether the PWR/OFF/BATT Switch is in either the "ON"
or “OFF" position. Typical recharge time 1s: ;o2en0urs
for a full charge. Minimum external DC input required
for full cha ge sisal oevoU
05
(ir
[NOTE]
The oven oscillator (Option 02 only) is powered
by the internal battery when the test set is
Switched to battery operation. In the battery
mode, there is no provision for preheating the
oven oscillator. A 15-minute warm-up period is
required, with the test set at room temperature,
in order to stabilize the oven oscillator.
However, the FM/AM-1200S/A will turn on and
Operate immediately in the battery mode, but the
Oven oscillator frequency will not be within
specifications without the required 15-minute
warm-up period. It is therefore recommended
that the FM/AM-1200S/A be connected to an
external AC or DC power source for the required
15-minute warm-up period.
2-4 GENERAL OPERATING DATA
The FM/AM-1200S/A Communications Service Monitor is shipped with the AC
Power Select Switch (Ref. Figure 2-3) positioned to "115 VAC". If it is
necessary to operate FM/AM-1200S/A using 220 VAC, the AC Power Select
Switch must be positioned to "230 VAC" prior to the application of
electrical power. The procedure to reposition this switch is as
follows:

Figure 3-4 Keyboard and VFD Layout
The FM/AM-1200S/A Keyboard and VFD (Vacuum Fluorescent Display) provides
a means of entering data into the microprocessor to control the various
operating parameters of the RF frequency, tone generator and duplex
generator offset frequency. Normal Keyboard operation involves the
following three basic types of key entry sequences:
A. @&OUREGI ee MODE
Key entries allow rnmieetie Cie programming and execution.
B. PROGRAM MODE
PROG Key entries allow retrieval, edit and storage without the
execution.
C. EXECUTE MODE
EXEC Key entries allow retrieval and automatic execution without
edit capability.
The primary objective of this subsection is to familiarize the operator
with the methods of making keyboard entries. A complete description of
the Keyboard and VFD operation is located in Section 4.

The FM/AM-1200S/A Keyboard consists of 24 keys which provide a means of
entering data into the microprocessor to control the frequency of the
signal generator, receiver, duplex generator offset and tone generator
functions.
3-3-1 FUNCTION KEYS
These keys determine what FM/AM-1200S/A function is selected by the
Operator. Most keys have a dual function which will select either the
lst order functions (DTMF, TONE, OFFSET and RF) or 2nd order functions
mets 1 SEQ, SCAN, DVM, DCS, BAUD, INT, STEP, METER, 10PS, 20PS and a
selection of 4 additional options).
Ist ORDER FUNCTIONS (Black Lettering on Keyboard)
These functions are used to set the operating parameters of:
Dual Tone Multiple Frequency (DTMF)
Variable Tone Generator (TONE)
Duplex Offset Generator Frequency (OFFSET)
Signal Generator or Receiver Frequencies (RF)
2nd ORDER FUNCTIONS (Blue Lettering on Keyboard)
All second order function keys must be preceded by the "2ND FUNCT" Key.

3-3-2 INSTRUCTION KEYS
These keys instruct the FM/AM-1200S/A processor to perform a specific
operation or function to permit the execution of a key entry. Specific
key functions are as follows:
2ND FUNCT Key - Conditions the FM/AM-1200S/A processor for a 2nd order
function entry; this key must precede the 2nd function
entry. When this key is depressed, the VFD will
display "2ND FUNCTION". 3
PROG Key - Allows entry into the programming parameters of the
FM/AM-1200S/A. All Keyboard entries are immediately
displayed on the VFD but will not be executed by the
processor,
EXEC Key - Retrieves stored data and automatically executes the
data.
ENTER Key - Instructs processor that the preceding key-in sequence
has been completed (i.e., RF Freq's, DTMF Sequences,
etc.). Depress ENTER Key twice to exit from execute
mode and return to the direct mode.
3-3-3 CURSOR CONTROL KEYS
The « and + Keys will move the cursor laterally within the VFD viewing
area for purposes of changing data values. To change a data value, the
cursor must be positioned directly on the desired character position
prior to making a value change. The t and ¥ Keys are used to increment
(4) or decrement (+) any value positioned in the cursor and any adjacent
values which are affected by "carry" and "borrow" operations. In addi-
tion, the ¢ or ¥ keys are used to slew through the stored memory fields.
3-3-4 DATA ENTRY KEYS
These keys include standard numerical value keys from 0 through 9, as
well as eight special symbol keys which are used to enter:
A. Decimal point (Justifies Tone, Offset and RF Fields)
B A change of sign (+/-) (Used with Offset, DCS and DVM functions
only)
oe A, B, C, D, # and * (telephone associated symbols), used in
conjunction with the DTMF or IMTS functions.
\NOTE}
A, B, C, D, # and * are also used fore program
preset position selections 10 through 15.
These data entry keys must be preceded by the
2nd Function Key.

4-2 DIRECT DATA ENTRY
The following steps describe the methods of making direct keyboard
entries to control the FM/AM-1200S/A RF Frequency, Offset Generator Fre-
quency and Tone Generator Functions. Once a particular function key is
depressed, the FM/AM-1200S/A assumes a programming/edit and execution
mode of operation. In this mode, the FM/AM-1200S/A will execute each
key entry, as it is selected, while allowing the operator the capability
to edit programmed data indicated on the VFD (37).
{CAUTION}
ANY CHANGES IN DATA WHEN OPERATING IN THE
DIRECT MODE WILL CAUSE CHANGES TO THE PRE-
PROGRAMMED MEMORY SETTINGS.

4-6-1 GENERAL
The FM/AM-1200S/A RF signal generator is capable of generating
calibrated amplitude signals within a range of 250 kHz to 999.9999 MHz,
in 100 Hz steps. The signal generator can be used to stimulate external
devices by generating modulated or unmodulated signals, while the
FM/AM-1200S/A receiver is simultaneously monitoring the generator.
Modulation signals for the generated carrier are available from the
FM/AM-1200S/A internal tone generators or from external audio sources.
A microphone input connector is also available for applying voice modu-
lation. The generated signals are transmitted out the FM/AM-1200S/A
front panel T/R Connector (11), at an output level which is continuously
Pa cioyyes” -20 to -127 dBm (using RF Level Attenuator Controls (9)
ma -|-L0)').
Table 4-7 outlines the parameters of the generated output, which can be
monitored by the FM/AM-1200S/A receiver circuits during generator opera-

4-7-1 GENERAL
In the Duplex mode of operation, the FM/AM-1200S/A has the capability of
generating and receiving signals simultaneously. While the FM/AM-
1200S/A receiver is monitoring the power, modulation and frequency
characteristics of the UUT transmitter, the FM/AM-1200S/A offset genera-
tor is simultaneously transmitting to the UUT receiver with a signal at
a fixed output level. This signal is not affected by the operation of
the UUT transmitter. FM/AM-1200S/A duplexer accuracy {setting up on
desired frequency) is +1.3 kHz
The FM/AM-1200S/A contains a duplex system which
is FM modulated only.
The FM/AM-1200A has an output level at the
DUPLEX Output Connector of -60 dBm +10 dB.
The FM/AM-1200S has two output levels available
at the DUPLEX Output Connector:
DUPLEX HIGH Mode: -15 dBm (2:0 dB) @ #49.99 MHz
from Receive Frequency
DUPLEX LOW Mode: -25 dB below DUPLEX HIGH at
the same frequency

within a range of 2 Hz to 10 kHz (in 0.1 Hz increments). The fixed tone
generator output is a 1 kHz sinewave. The frequency and wave shape of
the variable tone generator is selected by the FM/AM-1200S/A Keyboard
(18) and displayed on the VFD (37) when the Keyboard "TONE" key mode is
selected. The output level of each tone generator can be individually
controlled.

4-11 BASIC RS-232 OPERATION
This paragraph contains basic instructions for operating the FM/AM-
1200S/A using an RS-232 or GPIB compatible external device. Using these
instructions, the operator can select any available parameter of the
following FM/AM-1200S/A functions:
DTMF OF ESET IMTS (PULSE) METER
TONE RF TONE WAVEFORM DCS MODULATION
4-11-1 FM/AM-1200S/A INITIALIZATION
The initial communication between the FM/AM-1200S/A and the external
controller consists of Baud Rate synchronization. The external
controller can be set to any one of the following Baud Rates:
Te F300 5 - 4800
2 - 600 6 - 9600
3) =a 00 y es a2. Ut
4 - 2400
Use the following procedure to initialize the FM/AM-1200S/A for RS-232/
GPIB operation:
SLoe PROCEDURE
i Connect external controller to FM/AM-1200S/A at RS-232/GPIB
Connector (43).
2:3 Check FM/AM-1200S/A Protocol (Appendix B).
2ND 8
<p Press su] on the Keyboard (18), followed by the number
corresponding to the desired Baud Rate as shown above.
Example: Set Baud Rate to 4800
2ND 8 5
FUNCT BAUD OPT
"SET BAUD RATE 5" will be displayed on VFD (37).
4, Type two CR (carriage returns) on external controller. "RS-232
ENABLED" should be displayed on VFD (37).
te If a computer is available, a program may be used for control.
The following example will work on IBM-compatible types. Notice

4-11-2 RS-232 COMMAND PROCEDURE AND DATA STRUCTURE
All FM/AM-1200S/A functional commands and data information are trans-
ferred over the RS-232 as uppercase ASCII alphanumeric character strings
designed to replace the front panel controls.
All input commands sent to the FM/AM-1200S/A are placed in an internal
queue that will accommodate up to 128 bytes of data. Command strings
may be packed together, but the individual commands must be separated by
a colon ":" delimiter. The colon ":" may or may not cause the command
to be executed immediately, depending upon the type of external
controller being used. The following ASCII Characters will always ter-
minate the command or series of commands:
ASCII Carriage Return (0D) - CR
ASCII Line Feed (OA) - LF
Maximum command string length including spaces and delimiters is 128
characters. If the command string exceeds 128 characters, everything up
to the most recent delimiter will be accepted and the rest ignored. All
Spaces will be ignored except when using the "!" command.
Returned data to the external controller will not be packed together in
a string. Instead, each set of data returned will be on an individual
line and sent out in the order in which its command was sent. That is,
the first "get" instruction sent in a command string will cause the
returned data to be on the first line of the output; the second "get"
instruction will cause the returned data to be on the second line of the
Output, and so on.
Data inputs that are out of specific range will generally default to the
minimum values or initial condition values.

APPENDIX C - MINIMUM PERFORMANCE CHECK
C-1 GENERAL
This section contains a quick, qualitative, step-by-step check for
assessing the performance of the FM/AM-1200S/A. This check should be
used when the operating condition of the set is in question. The check
contained in this section is performed using the FM/AM-1200S/A front
panel controls and does not require the removal of the exterior case.
This check can be performed within 4 to 6 minutes, while the set is
operating on its own internal battery power. Only a two foot length of
502 coaxial cable (with BNC connectors on each end) is required as
accessory equipment to perform this check.
\NOTE}
If a determination is made that the FM/AM-
1200S/A is not performing properly as a result
of this performance check, the operator/
technician should perform a thorough laboratory
or bench check before taking any corrective
maintenance action.
C-1-1 PRECHECK CONSIDERATIONS
For maximum benefit of the performance check, it is strongly recom-
mended that personnel:
1, Thoroughly read and understand ail steps of the check prior
to actual initiation.
2. Be familiar with the FM/AM-1200S/A front and rear panel
controls, indicators and connectors, as described in Section
3 of this manual. The performance check assumes the
Operator/technician is familiar with the set.
