5.1.2.1 Specific Test Limitations and Discrepancies
While every effort has been made to provide comprehensive coverage of the Mil-Std 704 tests, some
limitations apply, largely due to hardware limitations of the iX power source. The following table lists
specific implementation issues by test number. The deviation from the standard requirement is shown
in the “Actual setting” column. The reason for the deviation is shown in the last column.
.5Vp-v modulation (.3536V RMS)
3.5Vp-v modulation (2.475V RMS)

Note: To perform MIL-STD-704F tests HDC105-1, -3 and HDC302-1, -3, it is advised to use the firmware revision E
tests TRANSIENT and ABNORMAL respectively. The –704 firmware implementation overrides the DC voltage range
hardware limit making it possible for these tests to be performed. If the i/iX system is a Series II system, the DC limit is
400V so this limitation does not apply. The same does not apply to the equivalent rev B or rev C tests, which require
475VDC. The 475 VDC level is not supported on any of the i/iX Series.
