8.7 MIL-STD 704 Rev A - F (-704F)
The following are the remote commands available for the –704F test option. There are two
firmware options available for MIL-STD 704 testing,the –704 option and the -704F option:
Option –704 covers revisions D through F and matches the traditional implementation
used on other California Instruments AC power sources. This mode provides shorted test
times but does not follow the test protocols that were published with revision F in 2004.
This option uses SCPI command syntax prefix MIL704 and is covered in this chapter.
Option –704F covers revisions A thorugh F and does follow the new test protocol
guidelines published in 2004. The –704F option uses SCPI command syntax prefix
MS704 and is covered in chapter 8.7.
The MS704 commands may be used to access the –704F option standard implementation on the
Ls/Lx Series. All commands for this option have a “MS704” prefix instead of the “MIL704” prefix
used for the legacy
–704 option. The –704F option implementation goes beyond the legacy
implementation used for revisions D and E of the MIL-STD 704 and incorporates all revisions from
A through F.
Note: The –704F was released with revision 1.00 of the Lx/Ls firmware. If your unit has a version
prior to this release, the MS704 commands will not be available. A firmware update will be
required to use this mode. Visit
www.programmablepower.com for update information.
The advanced version not only covers test levels, it also implements the recommended test
sequences to use as outlined in the new revision F Mil-Std document. This implies that the test
times are considerably longer than was the case before. For abbreviated tests, use the MIL704
command set documents in section 8.6.
The ABORt command will terminate the test in progress at any time. See the Lx / Ls Series II
User Manual (P/N 7004-980) for more details about the implementation of each 704 test step.
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.
Note that most of the MS704 commands do accept parameters or have a query format except
where indicated in the table.
Command Parameters
MS704:VERSion A, B, C, D, E or F
MS704:GROup SAC, SVF, SXF, TAC, TVF
MS704:FREQuency
MS704:STEP SINGle or CONTinous
MS704:TEST:CONDition A letter form A to Z or AA to ZZ function of test.
Programming Considerations
Several of the MIL-STD 704 test steps take considerable time to execute. (Refer to Lx/Ls User
Manual P/N 7004-980 for approximate test times. The *OPC command may be used to set the
OPC bit in the Event Status Register upon command completion. The Event Status Register OPC
bit can be enabled through the appropriate enable register to generate an SRQ if GPIB is used.
Alternatively, the *OPC? query commend can be used to poll for completion of the MIL704
command.
