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.
