9. Option -704: MIL-STD 704 Rev D through F (MIL704 Mode)
9.1 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 –704 option as implemented on the Lx/Ls Series only supports AC power applications. DC
mode is not available on the Lx/Ls Series so no DC tests are provided in the –704 option.
The Lx/Ls 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 (Option
–704) pre-dates the release of the test protocol handbook that accompanied revision F of the
standard. To test conform the suggested test protocol, use the MS704 test mode instead.
(Option
–704F, Refer to Chapter 10.)
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 Lx/Ls front panel.
9.2 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.
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 -EHV option output range pair (200/400V). If this option is not
installed, some tests will be skipped.
9.3 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.
