4. Transient high frequency test (Figure 8, page 135).
MIL704D :TRANsient :FREQuency:HIGH
This test will step up the frequency from 400 Hz to 425 Hz. The frequency will
step down to 400 Hz in the following sequence:
425 Hz for 1 second
420 Hz for 4 seconds
410 Hz for 5 seconds
407 Hz for 4 seconds
5. Transient low frequency test (Figure 9, page 135).
MIL704D :TRANsient :FREQuency:LOW
This test will step down the frequency from 400 Hz to 375 Hz. The frequency
will step up to 400 Hz in the following sequence:
375 Hz for 1 second
380 Hz for 4 seconds
390 Hz for 5 seconds
393 Hz for 4 seconds
6. Transient frequency test
MIL704D :TRANsient :FREQuency
This test will combine the high frequency transient and the low frequency
transient. There is a pause of 5 seconds between tests.
8.6.3. ABNORMAL
1. Abnormal overvoltage test (Figure 10, page 136).
MIL704D[A][B][C] :ABNormal :VOLTage :OVER
This test requires a 180 volt range. A range change will take place if the power
source is not set for the high range. The output voltage will drop temporarily to
allow for the range change and after 5 seconds the test will begin.
