9.6.1 Option –704: MIL-STD-704 rev D & E Tests. (Firmware)
9.6.1.1 General
The MIL704 option can perform 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.
9.6.1.2 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.
9.6.1.3 Revision
The MIL704 option defaults to Revision E. The System can perform 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. For these tests,
Revision E test levels are used despite the revision D selection.
All levels and timing in this document refer to Revision E. For Revision D, refer
to MIL-STD-704D date 9/30/1980
