1-24
(a) The dayside test bench uses four motors in the inner module 2A1A2 and
one motor in the OSA 2A1A1.
• Translator 2A1A2A1A1A8
• Translator 2A1A2A6A8
• 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
generator.
• Filter motor
• Diffuser motor
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
2A2A13.
One of the inputs is the Mimco temperature probe, which is used in the test
console test bench to provide high-accuracy temperature measurements.
In addition,
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).
• Microcircuit and heat sink assembly 2A1A2W54
• Microcircuit and heat sink assembly 2A1A2W55
• Photomultiplier and bracket assembly 2A1A1A7 (OSA)
(b) The nightside test bench uses two sensors in the heat source target
assembly 2A3A1A1 and-one in the optical assembly 2A3A1.
• Microcircuit and heat sink assembly (heat source A)
• Microcircuit and heat sink assembly (heat source B)
