In the specialized field of electromagnetic compatibility (EMC) and radio frequency (RF) engineering, precision is paramount. When testing antennas, engineers need to ensure that the environment they are using—whether an open-area test site (OATS) or an anechoic chamber—is not distorting the signals. The industry standard that defines how to verify these sites is .

To solve this, the standard utilizes three different antennas measured in pairs (Antennas 1 and 2, Antennas 1 and 3, and Antennas 2 and 3) over a highly reflective ground plane or in an anechoic chamber. By setting up a system of three linear equations, technicians can mathematically isolate and calculate the exact antenna factor for each individual antenna. Why "Free" PDF Downloads Are Problematic

: It provides a standardized method for calibrating antennas at a 1-meter distance

SAE ARP958, officially titled is an Aerospace Recommended Practice (ARP) published by SAE International. It is the definitive industry standard that describes a "standardized and economical method for the checkout and calibration of electromagnetic interference measurement antennas."

The SAE ARP 958 standard is a cornerstone for testing, specifically defining how to calibrate antennas used for measuring radiated emissions. While the full document is a paid standard, technical papers and draft critiques provide insight into its critical role in aerospace and military electronics. Core Purpose: 1-Meter Calibration

is an Aerospace Recommended Practice (ARP) that outlines the procedures for the electromagnetic calibration of antennas used for aeronautical emissions testing. Its primary focus is on establishing a standardized method for determining Antenna Factors (AF) across a broad frequency range (typically 20 Hz to 40 GHz). To solve this, the standard utilizes three different

To help you get exactly what you need for your testing setup, please let me know:

The central premise of SAE ARP958 is . This is a measure of the loss in signal strength between a transmitting antenna and a receiving antenna placed on a test site.

If the Antenna Factor is inaccurate, every single measurement taken during product testing will be wrong. This can lead to false passes (releasing a non-compliant product) or false fails (wasting time and money redesigning a compliant product). SAE ARP958 ensures that this factor is calculated with the highest possible degree of precision. The SAE ARP958 Calibration Methodology

The standard has undergone several revisions to incorporate new technologies and procedures. The most reliable method is to buy the

Most traditional commercial antenna calibration standards, such as ANSI C63.5 , require testing at 3-meter or 10-meter distances to approximate a "far-field" environment. SAE ARP 958 strictly mandates a between the transmitting source and the receiving antenna.

Electromagnetic Compatibility (EMC) testing requires absolute precision. When testing products for aerospace, military, or automotive applications, engineers must accurately measure radiated emissions. At the heart of these measurements is the antenna, and at the heart of antenna calibration is the Aerospace Recommended Practice .
