Note: For Ls Series AC sources without the
–ADV option installed, the harmonic
analysis and waveform acquisition functions described in this section are not
available. Contact
to upgrade the Ls AC Source with the
–ADV
option. The MIL-STD 704 stimulus can still be run however.
Revision F of the MIL-STD 704 provides additional detail on performance evaluation of the EUT
after running an immunity test. This is covered in test method 101 of each of the power test
groups. The Lx Series AC source and the Ls Series AC source with the
–ADV option provides
built-in measurement functions that can be used to evaluate EUT performance.
Note however that the maximum bandwidth requirement for current harmonic measurements of
the Lx/Ls Series is limited to 48KHz in single-phase mode and 16 KHz in three-phase range.
Harmonic components that fall outside this bandwidth are not reported (value of 0.00 is
returned).
The requirement for MIL-
STD 704 is 150 KHz so for EUT’s with high harmonic order currents, a
higher bandwid
th external power analyzer should be used in addition to the AC source’s
measurement system.
