power cable, six rf jumper cables (marked with

identification bands W1 thru W6), and a technical

manual is stored in the cover compartment. Spare

fuses, a spare pilot lamp, a tuning cover, and a

70-decibel (db) attenuator are stored on the inside of

the cover. Primary power for the test set is 115 volts

or 230 volts at a frequency from 50 to 100 Hertz

(Hz). The equipment contains a blower motor that

dissipates internal heat and provides forced air

cooling for the AN/ARC-54 chassis and power

supply modules under test.

b. A front panel connector is provided for each

AN/ARC-54 module to be tested The module tests

are performed by plugging an AN/ARC-54 module

into the specified connector on the test set, making

specified switch setings, and then noting the meter

reading. Function switches on the test set connect

the outputs of the various power supplies and

oscillators to the module under test. The function

switches also connect the module outputs to the

correct load and meter circuit. The meter provides a

relative indication of the performance of each

module circuit. Radio frequency voltages at 3

MegaHertz (MHz) and above are applied to the

modules under test through the rf jumper cables

from rf connectors on the test set.

c. The test set includes a self-check feature that

enables the operator to monitor the output of the

internal power supplies, oscillators, and other in-

ternal circuits on the front panel meter. This same

feature is used during the module tests to adjust the

oscillator output levels to specified values without

using an external meter.
