Verify that the light beam after going through optics shows no loss
caused by optics.
(2) Test Console Test Bench.
The test console test bench serves as the control
and communications link between the electronics station and the dayside and nightside
test benches.
The following describes the purpose of each of the assemblies in the
test console test bench.
Programmable digitizer 2A2A1 - measures pulses and waveshapes, which are
stored in memory and compared against limits.
VHF cable entry panel 2A2A2 - provides BNC connectors for cable hook-up
during testing.
Optical signal generator assembly 2A2A3 - tests TV sensor, E/O
multiplexer, and visual multiplexer.
Test adapter panel assembly 2A2A4 - provides interface-between the E/O
test bench set and the major test adapter.
The major test adapter is used
during self-test and UUT testing.
Multiprogrammer assembly 2A2A6 - converts a single input/output channel
into multiple input/output channels.
Electronics drawer assembly 2A2A7 - provides a video signal generator,
motor control, temperature measurement, programmable pulse generators,
video camera controls, and solid state relays.
Extender assembly 2A2A8 - extends the IEEE 488 bus to the E/O test bench
set.
Matrix switch assembly 2A2A1O - provides 120 data lines to the UUT.
Multiprogrammer extender assembly 2A2A11 - extends the number of
input/output channels.
Switch controller assembly 2A2A12 - provides commands for controlling the
matrix switches.
Analog to digital converter assembly 2A2A13 - processes analog signals to
digital data.
(3) Nightside Test Bench.
The nightside test bench is comprised of two major
assemblies:
Nightside optical assembly
Pneumatic control panel
(a) The nightside optical assembly provides test devices to test the TADS
night sensor assembly and the PNVS turret assembly.
