Scope
This AIR provides guidance to the EMI test facility on how to check performance of the following types of EMI test equipment:
-
Current probe
-
Line Impedance Stabilization Network (LISN)
-
Directional coupler
-
Attenuator
-
Cable loss
-
Low noise preamplifier
-
Rod antenna base
-
Passive antennas
All performance checks can be performed without software. A computer may be required to generate an electronic or hard copy of data. This is not to say that custom software might not be helpful; just that the procedures documented herein specifically eschew the necessity of automated operation.
Rationale
The Air Force has suggested a change to 4.3.11 of MIL-STD-461 which would require a calibration standard for items that don't normally need to go to a metrology laboratory for calibration. Traditionally the SAE has provided this service (viz, ARP936 for feedthrough caps and ARP958 for antenna calibration) so that the MIL-STD need merely reference the appropriate industry standards.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
