SAE ARP958 is a standard published by SAE International (formerly the Society of Automotive Engineers). Its full title is Electromagnetic Interference Measurement Antennas; Standard Calibration Method .

If you are searching for a download, this comprehensive guide will break down what the standard covers, why it matters, how it dictates antenna calibration, and the legal compliance realities surrounding access to the official document. What is SAE ARP 958?

It establishes standard methods to calculate antenna factors. sae arp 958pdf free

The standard’s primary application is for use when performing EMI measurements at a distance of one meter (1 m) between the antenna and the source of interference, a configuration which is the cornerstone of many military and commercial EMC test standards. Essentially, ARP958 answers a critical question: how do you know that the EMI you are measuring is accurate? It provides the technical blueprint for calibrating the antennas used to detect interference in the first place.

The core methodology detailed in SAE ARP 958 is the . This technique allows labs to determine the exact antenna factor without needing a previously calibrated reference antenna. SAE ARP958 is a standard published by SAE

At its core, the method outlined by ARP958 uses two antennas: one as a transmitter and one as a receiver. The process measures the "insertion loss" of the signal between them. By comparing the power transmitted to the power received, the (AF)—a key coefficient that translates a voltage measured at the antenna into an actual electric field strength—can be reliably determined.

If you purchase a calibrated EMI antenna (such as a biconical, log-periodic, or horn antenna) from a reputable manufacturer, they often provide free application notes, white papers, and user manuals. These documents frequently explain how they apply SAE ARP958 compliance to their calibration processes, offering valuable technical insights without requiring you to buy the full standard. 4.
