The primary technique used to determine the absolute gain and antenna factors without relying on a pre-calibrated reference antenna.

The most secure method is purchasing the document directly from the SAE International website. Buying the official PDF ensures you receive the most current revision, complete with valid licensing for your organization. 2. Corporate or University Library Subscriptions

is the definitive engineering standard used to calibrate antennas at a close one-meter distance for electromagnetic compatibility (EMC) testing. Formally maintained by SAE International, its full title is Electromagnetic Interference Measurement Antennas; Calibration Method .

Specific guidelines on antenna spacing, height above the ground plane, and polarization to minimize reflections and proximity effects.

, it attempts to resemble reality by using another antenna that represents a distributed source in the calibration method. The primary technique used to determine the absolute

Do you need assistance finding (like IEEE or CISPR)?

The most reliable method is to buy the current revision directly from the SAE International website. They offer single-user digital PDFs and printed copies.

Free PDFs uploaded to unauthorized forums are often the product of optical character recognition (OCR) scanning. OCR software regularly misinterprets complex mathematical formulas, superscripts, and subscripts. In EMC engineering, a misplaced decimal or a misread formula can lead to catastrophic calibration errors. 3. Cyber Security Hazards is the definitive engineering standard used to calibrate

When test labs measure radiated emissions from an aircraft component or military device, they use antennas to collect electromagnetic signals. To convert the raw voltage measured by a receiver into actual electric field strength, engineers apply a correction factor known as the . SAE ARP 958 provides the exact mathematical formulas and physical setup requirements to calculate these Antenna Factors accurately, focusing primarily on the 20 Hz to 40 GHz frequency range. The Core Technical Methodology: The Three-Antenna Method

The scope of SAE ARP958 is specific and crucial for several global test standards. The standard outlines a method for calibrating broadband antennas within a shielded room, a critical controlled environment for EMC testing. Its application is for measuring a source one meter from the antenna, the typical distance used when performing military EMC testing per documents like MIL-STD-461.
