9.4 Option –704: MilStd704 Tests
The MIL704 option is made up of both firmware that resides in the power source and the Virtual
Panels Windows application program. The firmware covers revision D and E of the Mil-Std704
standard. The Virtual Panels covers the remaining revisions A, B, C and F. This provides
coverage of all available standard revisions.
The user interface for each implementation is different, however. The revision D and E tests can
be operated directly from the power source’s front panel or through the supplied Virtual Panels
program. The revision A-C, F tests can only be operated through the supplied Virtual Panels
program. Thus, for rev A-C and F, a Windows PC and interface is required.
Section 9.4.1 covers operation of the firmware based revision D and E tests.
For information regarding the operation of the MIL-STD-704 revision A, B, C, and F tests with
the Virtual Panels, please refer to the Avionics Software Manual (CI part no. 4994-971 included
on CDROM). Note that future updates of the Virtual Panels may include overlapping coverage
for revisions D and E in the software as the Virtual Panels program is designed to support all
revisions. For now, revisions D and E have no associated data files in the Virtual Panels.
9.4.1 General
This user manual assumes that the user is familiar with the text of the relevant MIL-STD 704,
test standard. No attempt is made to explain or elaborate on the actual test specification.
The MX15 supports two different implementations of the MIL-STD 704. This chapter covers the
legacy implementation referred to on the menu screens as MIL704. This implementation pre-
dates the release of the test protocol handbook that accompanied revision F of the standard.
Test Execution Considerations
Several of the MIL-STD 704 test steps take considerable time to execute. Tests in progress may
be aborted by using the BACK button on the MX15 front panel.
9.4.2 Initial Setup
Nominal parameters for the AC Power source are as follows:
Output Voltage
115V L-N or 230V L-N
Output Frequency
360 Hz to 800 Hz for all revisions.
60 Hz for revision F only.
Nominal parameters for the DC Power source are as follows:
Output Voltage
28V or 270V L-N
Note: A setting outside these nominal values will disable the test and will prevent
access to the 704 Menu screens or execution of any test step. To execute all tests
for the 230V L-N, the power source must be capable of programming 360V RMS.
This requires the -HV option. If this option is not installed, some tests will be
skipped.
9.4.3 Test Revision
The MIL-STD 704 option is capable of performing all sub-sections of MIL-STD 704 revision D, E
or F. A selection is made available to specify the revision of standard to be applied to the EUT.
The MIL704 option defaults to Revision E.
