1-24. TEST CONSOLE TEST BENCH 2A2 (cont)
(a) The dayside test bench uses four motors in the inner module 2A1A2 and
one motor in the OSA 2A1A1.
Automatic focus control 2A1A2A12
Filter wheel/motor assembly 2A1A2A10
Focus motor 2A1A1A4 (OSA)
(b) The nightside test bench uses one motor (2A3A1A1A10) in the heat
source target assembly 2A3A1A1.
(c) The test console
test bench uses three motors in the optical signal
Flip mirror motor
(7) Temperature Measurement CCA 2A2A7A6A4.
The temperature measurement CCA
2A2A7A6A4 (FO-27) receives inputs from several sensors and after amplifying, detect-
ing, and comparing, it transmits responses to the analog to digital converter
One of the inputs is the Mimco temperature probe, which is used in the test
console test bench to provide high-accuracy temperature measurements.
there are three temperature sensors in the dayside test bench and three in the
nightside test bench.
(a) The dayside test bench uses two temperature sensors in the inner
module and one in the optical signal analyzer (OSA).

(b) The nightside test bench uses two sensors in the heat source target
assembly 2A3A1A1 and-one in the optical assembly 2A3A1.
