MIL-DTL-87104C
d.
Test shall be conducted while the test sample is being subjected to the high temperature and high altitude
e.
The VSWR of the load shall be a minimum of 1.75:1.
4.6.2.6.2 Procedure.
a.
The assembly shall be placed in the test chamber and the power handling capability of the test sample shall
be determined by energizing the test sample at full rated power as specified in the detail specification.
b.
The time period for the low and middle frequencies tested shall not be less than 20 minutes. The time
period for the high frequency tested shall not be less than 1 hour.
c.
The chamber and equipment temperature shall be returned to, and stabilized at, room temperature
(see 4.3.1.1) between each application of high power.
d.
The assembly shall be subjected to the peak power specified in the applicable detail specification for a
period of 1 hour within 10 percent of the specified high frequency.
e.
At the conclusion of the power handling test, the assembly shall be removed from the chamber and shall be
subjected to examination of product, procedure II (see 4.6.1.2) and a gauge test as specified in 4.6.3.1.
4.6.2.6.3 Accept-reject criteria (see 3.5.1.7). If the assembly completes power test without breakdown and passes
the accept-reject criteria of 4.6.1.2.2 and 4.6.3.1.3, the equipment shall be considered to have passed the test.
4.6.2.7 RF leakage test (see 3.5.1.9). The RF leakage test shall determine that the RF energy leaked from an
assembly is within specified limits.
4.6.2.7.1 Test setup.
4.6.1.7.1.1 Test equipment. Test equipment used to perform the RF leakage test shall meet the requirements of
4.3.4. The test equipment listed on sheet 1, figure 1, shall be required to perform this test and it shall be capable of
performing satisfactorily throughout the design frequency range of the assembly. The apparatus described on sheets
2 through 7 of figure 1 shall also be required.
4.6.2.7.1.2 Test conditions. Test shall be conducted under room ambient conditions (see 4.3.1.1) and as specified
herein.
4.6.2.7.2 Procedure.
a.
Test frequencies shall be selected to insure complete scanning of the design frequency range of the
assembly.
b.
RF leakage measurements shall be made at each interface and, for braid shield constructions, at a
minimum of three points along the cable component of the coaxial assembly, when applicable.
c.
The test routine for a single test frequency at a particular point shall be as follows:
(1) Recorder calibration:
Step 1: Connect the test equipment as shown on figure 1, sheet 8.
