GENERAL SUPPORT MAINTENANCE INSTRUCTIONS

5-1.

S C O P E . This chapter provides the information required for general support

m a i n t e n a n c e personnel to perform the maintenance tasks authorized in the mainte-

nance allocation chart (MAC). Maintenance is performed using Electronic Equipment

Test Station AN/USM-410 for those items listed in table 5-1. Manual testing

p r o c e d u r e s are provided for those modules not tested on the AN/USM-410. These

m o d u l e s will be evacuated to SIG/INT EW Section for diagnostic testing and repair.

TEST LEVEL DESCRIPTIONS. Four levels of test can be performed using the

AN/USM-410.

The levels are defined as follows:

Level 1.

Go-chain (performance) test at unit level. No disassembly is

required.

b. L e v e l 2 . Unit level diagnostic tests necessary to isolate faults to a

printed circuit assembly/module; or a functional group of printed circuit

assemblies/modules.

Minimal disassembly is required for testing.

c. L e v e l

Go-chain (performance) tests at printed circuit assembly/module

level.

d . Level 4. Printed circuit assembly/module level diagnostic tests necessary

to fault isolate to the active piece part/functional group.

5 - 3 . T E S T P R O C E D U R E S . Tests for each unit under test (UUT) specified in

t a b l e 5-1 require Interface Devices (ID) and cables to connect the UUT to the

AN/USM-410.

T h e required items of test equipment for each UUT are identified in

Interconnection data is shown in the referenced figure. Automatic

T e s t Equipment Software Programs (ATESP) written for the UUTs specified are stored

TPT

o n Test Program Tape (TPT) and are identified by a specific TPT number.

number, program entry points, and file names are listed in table 5-1. Operation

o f the AN/USM-410 is described in technical manual Test Station Electronic Equip-

ment AN/USM-410(XE-3A)(V) PDEP11-6625-2773-12-3.

T h e test procedure for each UUT

is as follows:

Pre-test

inspection:

(1) Inspect the UUT as described in table 5-2.

(2) Correct any defects found before beginning testing.
