When an EMI receiver measures a signal, it records a voltage (in dBµV). However, compliance standards specify limits in terms of electric field strength (dBµV/m). The Antenna Factor is the mathematical bridge between these two values: How to Access SAE ARP 958 Legally Demystifying

. It is primarily used to determine "Antenna Factors" for equipment testing at a distance of 1 meter in shielded rooms. SAE International Key Features of SAE ARP958
SAE ARP 958 defines the procedures for calibrating antennas used to measure radiated emissions from electronic equipment. Unlike other standards that focus on far-field measurements (where the source is very distant), ARP 958 is unique because it focuses on near-field
Since its original release in 1968 (which only covered log-spiral antennas), the document has evolved through several key revisions: Revision A (1992):
