3-4. GENERAL.
This section describes the UUT test for the PNVS NSA. It includes an explanation of the way testing is
accomplished and a description of the test.
3-5. TEST CONCEPT.
The UUT test for the PNVS NSA is supplemented by procedures in section III of this chapter, and by
illustrations in section IV. While you are performing the UUT test, message prompts on the VDT will
direct you to perform one of the procedures in section III, or to locate a part of the PNVS NSA in section
IV.
a. Procedures. Section III contains procedures to install and remove the PNVS NSA and associated
adapters from the nightside test bench, to perform boresight displacement measurement, and to operate
the EETF pneumatic system. These procedures do not apply to the VUT test until called for by the test
program. At the appropriate time during the test, a message prompt on the VDT will direct you to perform
the procedures in one or more paragraphs in this section. At that time, turn to the referenced paragraph
and perform those procedures, as the program cannot continue until they have been performed.
b. Illustrations. Section IV contains illustrations showing different views of the PNVS NSA and calling
out components that require some operator action. In addition, the illustrations have warning notes that
call your attention to high voltage, moving fans, and high temperature areas on the PNVS NSA. At the
appropriate time during the test, a message prompt will refer to an illustration in section IV. Turn to the
referenced illustration for assistance while performing the following instructions on the VDT.
3-6. TEST DESCRIPTION.
When the VUT test program has run the selected self-tests and the PNVS NSA has passed the
cooldown test, the following menu will be displayed on the VDT:
