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.
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.
i

SECTION 4 - OPERATION
ContaTns-Tnstruct1ons for operating the FM/AM-12005/A Keyboard
and VFD. Using the Keyboard, the operator can enter data into
the FM/AM-1200S/A in the following modes:
1. Direct 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-12DOS/A.
SECTION 5 - AVAILABLE OPTIONS
fOntaTns-descrTpt1ons-and-operating procedures of available
options to the FM/AM-120DS/A.
Useful supplementary information relating to the operation of the
FM/AM-1200S/A is contained in appendices at the rear of the manual.
(See Table of Contents for a detailed list of manual contents.)

SECTION 1- INTRODUCTION
1-1 GENERAL
The FM/AM-1200S/A is a microprocessor controlled, rligitally 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
Communication Receiver
Digital Voltmeter (Option)
Oscilloscope
1 kHz (Fixed) Tone Generator
Variable Tone Generator
(Programmable)
DTMF Encoder
DTMF Decoder (Option)
Power Meter
Frequency Error Meter
Modulation Meter
SINAD Meter
Audio Error Meter
Signal Strength Meter
DUPLEX Generator (with
a selectable offset)
Spectrum Analyzer
(FM/AM-1200S only)
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 g99.9999 MHz
(in 100 Hz steps\, at an output level which is continuously variable
from -20 to -127 dBm. The generated tarrier 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.
