SECTION X
DEPOT OVERHAUL STANDARDS

10-1. Applicability of Depot Overhaul
        Standards

The tests outlined in this section are designed to measure the perfomance capability of repaired equipment. Equipment that is to be teturnend to stock should meet standards given tests.

10-2. Applicable References

  1. Repair Standards. Applicable procedures of depots performing these tests and the general standards for repaired electronic equipment given in TB SIG 355-2, and TB SIG 355-3 form a part of the reqyuirements for testing this equipmenr.

  2. Modification Wirk Orders. Perform all modification Work Orders applicable to this equipment before making the tests specidied. DA Pam 310-7 lists all available MWO's.

10-3. Test Facilities Required

The following equipment or suitable equivalents will be used in determining compliance with the requirements of this specific standar.

  1. Test Equipment. Spectrum Analyzer AN/URM-134A (spectrum analyzer) is the only test equipment required.
