This paragraph explains the purpose of the EETF TADS/PNVS Augmentation Equipment.
A brief functional description is given, followed by a more detailed description, of
each of the units in the electronic station, dayside test bench, test console test
bench, and nightside test bench.
Also, the electro-optical (E/0) test bench set
pneumatic leveling and isolation system is described.
Finally, the test program sets
(TPS) are described.
a. ELECTRONIC STATION
The electronic station functions as the control and communication link between the
AN/USM-410 electronic equipment test station and the E/O test bench set. It provides
electrical interface, buffering, power supplies and stimulus measurement. The
following describes the purpose of each of the assemblies in the electronic station:
Control unit assembly 1A1 - senses and controls IR heat sources, which are
located in the nightside test bench.
488 controller power supply assembly 1A2 - provides digital to analog conver-
sion for voltage control of the four programmable power supplies.
Programmable power supply assembly 1A3 - supplies two voltages of O to 36 vdc,
and two voltages of O to 75 vdc.
DC power supply assembly 1A4 - supplies +15 vdc, -15 vdc, +5 vdc, and +28 vdc.
AC control panel assembly 1A5 - provides control and protection of 115 vac for
units in electronic station and E/O test bench set.
PMT controller 1A7 - senses and controls temperature of PMT housing in OSA.
Extender assembly 1A9 - extends the IEEE 488 bus between the test station,
digital computer assembly 1A11, and E/O test bench set.
