AM5(e) Classic Instruction Manual (18-0047) DESCRIPTION
November 19, 1997
CAUTION
When using the padded carrying case for the AM5 or AM5e Classic
(P/N 87-0070C), DO NOT PLACE the power cord around the side of the
case in the manner demonstrated in Figure 1.
Instead, be certain to WIND THE CORD UNDER THE CASING in the
Area between the feet, as shown in Figure 2.
Failure to follow this procedure could cause deterioration of the cord and
Increase the possibility of electric shock.

ORGANIZATION OF MANUAL
SECTION 1 — OVERVIEW/UNPACKING describes the models of the AM5 and
AM5e Classic that are available and provides guidance for proper
unpacking and inspection of the unit.
SECTION 2 — POWER CONSIDERATIONS describes the commercial power
requirements, precautions, battery options, and power ON and
OFF.
SECTION 3 — PHYSICAL AND FUNCTIONAL DESCRIPTION describes the
physical characteristics; front-panel switches, indicators, displays,
and connectors; rear-panel power connector, voltage-select switch,
fuse location, method of identifying units, and permanent
connections. Also described in this section are the Factory-
installed options and accessories.
SECTION 4 — SELF TEST OPERATIONS describes the operations which should
be performed after the unit is turned on for the first time. Default
settings are described and SEND and MEASURE tests that can be
performed by connecting the TX/2W to the RX jacks are described.
This section also describes restoration of settings before shut down
and a full-calibration procedure.
SECTION 5 — LINE TEST CONNECTIONS AND CONFIGURATIONS describes
the cables that may be used to connect the unit to the equipment
under test. Also covered are schematic diagrams of the line
interfaces for the various configurations that can be selected by an
operator through the use of the TX/2W. RX, LINE, and DIAL
sections of the front panel.
SECTION 6 — MEASURE FUNCTIONS AND PARAMETERS describes each
measurement that may be selected by the MEASURE key on the
front panel. Included in the description are all parameters that
may be changed for each type of measurement. Some typical test
configurations are covered.

SECTION 7 — FILTERS FOR AM5 Classic describes the Noise-Weighting filters
that are provided to IEEE standards.The Filters are switched by
the FILTER key into the measurement circuitry for noise tests.
Included in these sections are frequency response graphs for each
filter type.
SECTION 8 — FILTERS FOR AM5e Classic describes the Noise-Weighting
filters that are provided to CCITT standards.The Filters are
switched by the FILTER key into the measurement circuitry for
noise tests. Included in these sections are frequency response
graphs for each filter type.
SECTION 9 — SEND FUNCTIONS AND PARAMETERS describes each signal
generation function that may be selected by the SEND key on the
front panel. Included in the description are all parameters that
may be changed for each signaling requirement.
SECTION 10 — AM5/AM5e CLASSIC TECHNICAL SPECIFICATIONS provides a
tabular listing of the specifications for the AM5 Classic and the
AM5e Classic.
SECTION 11 — WARRANTY AND SERVICE POLICY provides information on
warranty and on returning unit to Ameritec for service.
