Product Code:SAE ARP958
Title:Electromagnetic Interference Measurement Antennas; Standard Calibration Method
Issuing Committee:Ae-4 Electromagnetic Environmental Effects (E3) Committee
Scope: This SAE Aerospace Recommended Practice (ARP) outlines a standard method for the checkout and calibration of electromagnetic interference measurement antennas. Its primary application is for use when measuring a source 1 m from the antenna in a shield room versus a source at a greater distance (far field). This is the typical distance used in performing military EMC testing. Thus, this is a method of calibration. Shield room characteristics are not considered. It does not address an unknown distributed source. Yet it is close to reality since it is based on another antenna that represents a distributed source. This document presents a technique to determine antenna factors for antennas used primarily in performing measurements in accordance with 2.1 and 2.2. The purpose of Revision B is to include the calibration of other antennas, such as small loop antennas that are also specified for use in these same references. Revision D includes a specific procedure for loop antennas that are separated by 1 m from the device under test. The Scope of Revision E is as follows: revision of main calibration method; update of process to reflect modern test equipment (i.e., network analyzers); inclusion of measurement uncertainty estimates; and resolution of conflicts between main method and alternative method suggested in Appendix C
