9.8.1 Option –704: MIL-STD-704 rev D & E Tests. (Firmware)
9.8.1.1 General
The MIL704 option is capable of performing most sections of MIL-STD-704 rev D and E in either
of the AC or DC mode.
Note: The Distortion Spectrum tests:
Table I and II, Figure 7
Table III, Figure 12
Table IV, Figure 18
are not supported by the
–704 option. These tests require the use of additional
external equipment.
9.8.1.2 Initial Setup
Nominal parameters for the AC Power source are as follows:
Output Voltage 115V L-N
Output Frequency 400 Hz
Nominal parameters for the DC Power source are as follows:
Output Voltage 28V or 270V L-N
A setting outside these nominal values will disable the test and will prevent access to its Menu
screens.
9.8.1.3 Revision
The MIL704 option defaults to Revision E. The System is capable of performing
Revision D test by changing the selection to Revision D. All Revision D tests can be performed
except for the 270V DC TRANSIENT and ABNORMAL where Revision E level are used despite
the revision selection.
All levels and timing in this document refers to Revision E. For Revision D refer to MIL-
STD-704D date 9/30/1980
