Description
This module tests the ability of shutter assembly 2A1A2A2 to
respond to open and close commands. The dayside test bench is
cleared and the shutter assembly sensors checked for position 2
(closed).
If the sensors indicate position 1 (open), a prompt is displayed
at the completion of the test.
The shutter assembly is then programmed to open, and the shutter
assembly sensors checked for position 1.
If the sensors indicate position 2, a prompt is displayed at the
completion of the test.
The shutter assembly is then programmed to close, and the shut-
ter assembly sensors checked for position 2.
If the sensors indicate position 1, a prompt is displayed.
This module tests the optical alignment assembly through various
voltage and resistance measurements.
The values are compared to upper and lower limits and if an
error is detected, a prompt is displayed at the end of the test.
Effectivity:
Used with E/O bench equipped with optical signal
analyzer only.
This module tests OSA self-test cables 13083701 and 13083702 by
measuring pin to pin continuity, and insulation resistance.
If an error is detected, the operator is prompted to repair or
replace the cable.
