User Manual
8.4 Option –704: MilStd704 Tests
The MIL704 option is made up of both firmware that resides in the power source and the GUI
Windows application program. The firmware covers revision D and E of the Mil-Std704 standard.
The GUI 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 GUI program.
The revision A-C, F tests can only be operated through the supplied GUI program. Thus, for rev
A-C and F, a Windows PC and interface is required.
Section 9.8.1 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 GUI, please refer to the Avionics Software Manual (CI part no. 4994-971 included on
CDROM). Note that future updates of the GUI may include overlapping coverage for revisions D
and E in the software as the GUI program is designed to support all revisions. For now,
revisions D and E have no associated data files in the GUI.
