2-1. TEST PREPARATION.
No special procedures are required to prepare the TADS Night Sensor Assembly (NSA) for test. Refer to
the UUT/TPS/interface device matrix tables in appendix B to determine the correct UUT test program
part number for the TADS NSA. Then refer to the UUT test program for a list of cables, test equipment,
and test accessories required to test the TADS NSA.
2-2. UUT DESCRIPTION.
The TADS NSA (figure 2-1) is a forward looking infrared (FLIR) target imaging and designating assembly
that converts IR image scenes into video to be used for target designating and tracking. It contains no
operating controls or indicators. All components of the TADS NSA that are referenced during the UUT
test are shown in the illustrations in Section IV.
2-3. PRECAUTIONS.
The TADS NSA is an electro-mechanical device containing delicate electro-optical components. Use
extreme care when handling the TADS NSA to prevent damage to these components. Observe the
following general guidelines when lifting or moving it.
a. Weight. The TADS NSA weighs 55 pounds. Always get help when lifting or moving it.
b. Optics. Do not touch optics assemblies with your bare hands. Do not use the optics assemblies for
any purpose when lifting the TADS NSA. If you accidentally place any pressure or force on the optics
assemblies, you could contaminate or damage them, or cause misalinement. Whenever possible, mount
the TADS NSA onto its handling fixture when movement is necessary.
