9.4 Option –704: MilStd704 Tests
The MIL704 option is made up of both firmware that resides in the power source and the MXGui
Windows application program. The firmware covers revision D and E of the Mil-Std704 standard.
The MXGui 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 MXGui program.
The revision A-C, F tests can only be operated through the supplied MXGui 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
MXGui, please refer to the Avionics Software Manual (CI part no. 4994-971 included on
CDROM). Note that future updates of the MXGui may include overlapping coverage for revisions
D and E in the software as the MXGui program is designed to support all revisions. For now,
revisions D and E have no associated data files in the MXGui.
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.
