materials as defined in 3.5.3 in its design or construction.
4.5.4 Mechanical/Electrical Interchangeability. Verify that like units, assemblies,
subassemblies and parts are electrically interchangeable with those of the CM Test Set
without additional wiring, calibration or adjustments beyond what is normally required at
time of manufacture. The CM Test Sets shall be in compliance with 3.5.4 herein.
4.5.4.1 Dimensional Interchangeability. Verify that like units, assemblies, subassemblies
and parts are dimensionally interchangeable with those of the CM Test Sets to determine
compliance with 3.5.4 herein.
4.5.4.2 Dimensions and Weight. The dimensions of the CM Test Sets and carrying case
shall be measured and shall meet the requirements of 3.3.2. The CM Test Sets, carrying case
and cables shall be weighed and shall not exceed the total weight specified in 3.3.2.
4.5.5 Bounce Preconditioning. Subject the CM Test Sets to bounce preconditioning in
accordance with 3.5.5.
4.5.6
Burn-In. Conduct burn-in of the CM Test Sets in accordance with 3.5.6.
NOTE: The CM Test Sets shall be submitted for Burn-in after the conduct of bounce
preconditioning of 3.5.5 and verification of this requirement. Burn-in shall be conducted
prior to the conduct of any other tests.
4.5.7 Electrical Requirements. Verify that the CM Test Sets meets the requirements
stipulated in 3.5.7. The Performance Test Procedure for AN/ALM-178( ), SM-D-883939, is
recommended and may be used for guidance in determining methods to demonstrate
compliance with 3.5.7.
4.5.7.1 Input Power. Verify that the CM Test Sets operates on a specified input power of
27.5 volt (DC), +1.5 volts (DC) at 260 milliamperes (mA).
4.5.7.2 CM Test Set ON-OFF Control. Verify that the CM Test Set, AN/ALM-178,
provides ON-OFF control of the 28 volt (DC) power to the transmitter of the
Countermeasures Set, AN/ALQ-144( )(V)1 and 3.
Verify that the CM Test Set, AN/ALM-178A, provides ON-OFF control of the 28
volt (DC) power to the transmitter of the Countermeasures Set, AN/ALQ-144( )(V)1, 3 and
5.
4.5.7.3 CM Test Set Power Control. Verify attainment of 3.5.7.3.
4.5.7.4 CM Test Set Output Control. Verify attainment of 3.5.7.4.
