MIL-T-81782C(AS)
3.6.1.6 Simulator, Electronic Command Signal SM-657( )/AWM-23(V). The
electronic command signal simulator shall contain the logic necessary to
control and monitor either the signal data converter or LTC WRAs. The
drawer shall also contain the simulation functions needed for simulating
either the signal data converter WRA or the LTC WRA.
3.6.1.7 Housing connector assembly - loop test, relay matrix. The
housing connector assembly shall provide circuitry to permit self-test of
the relay switched signal channels when an LTC WRA is not connected. A
dc voltage shall be applied to all signal channels through a buffering
resistor to allow each channel to be individually switched and monitored.
3.6.2 Console, Test, Computer OJ-257( )/AWM-23(V). Computer test
console (bay no. 2) shall operate in conjunction with computer test console
(bay no. 3) to provide test positions for testing of the computer subsystem
WRAs.
3.6.2.1 Ac and dc radiometer - voltmeter (DRVM).  A DRVM, Dana, 5743-S-
2181A, or equivalent, shall be supplied and shall be capable of measuring
resistance, ac and dc voltages and ac voltage ratios to test the WRAs under
automatic station control.
3.6.2.2 Programmable counter/timer.  A programmable counter/timer,
Monsanto 110B-021B, or equivalent, shall be supplied and shall be
capable of measuring frequency, pulse width, pulse count, and time inter-
vals to test the WRAs under automatic station control.
3.6.2.3 Indicator, Data Display IP-1129( )/AWM-23(V).
The data display
indicator shall be capable of presenting visual displays of test station
functions, status, and test data which are to be monitored by the operator.
3.6.2.4 Mounting MT-4505( )/AWM-23(V).  The WRA mounting shall be a dual
carrier used in three WRA configurations.  When testing a data processor
the mounting shall hold the data processor and the power supply and bulk
store loop test adapter (3.6.2.6) and shall provide the interface between
the CTS and these units.  When testing a PS/S, the WRA mounting shall hold .
the data processor simulator and the PS/S and shall provide the interface
between the CTS and these units.  When neither WRA is being tested, the
mounting shall hold the power supply and bulk store loop test adapter and
the data processor simulator for self-test.
3.6.2.5 Simulator, data processor. The data processor simulator shall
provide an interface with the digital computer for testing the input/output
channel of the digital computer, with the PS/S for testing the bulk store
functions and with the system interface simulator (SIS) for self-test of the
SIS.  When a tactical data processor is to be tested, the data processor
simulator shall be stored in the WRA stowage area provided in bay no. 4.
