In-House Verification of EMI Test Equipment
AIR6236A
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 only change to this revision is within the Rationale as follows: MIL-STD-461 no longer requires the routine calibration of many types of EMI test equipment. This AIR provides the EMI test facility with procedures that can be performed in-house using their own EMI test equipment to check that the devices no longer requiring calibration nevertheless are performing properly to manufacturer’s specifications. These procedures can be performed to check that the transducer factors entered into EMI test software haven’t changed, or in the case where a MIL-STD-461 measurement system integrity check indicates a problem, they serve as a quick check of the transducer’s integrity.
AIR6236A has been reaffirmed to comply with the SAE Five-Year Review policy.
