SAE ARP 958 is an indispensable document for any facility performing EMC testing, particularly under MIL-STD-461. The 1-meter calibration method outlined ensures that antenna factors are accurately determined. For the most accurate, compliant, and up-to-date procedures, professionals should access the latest document through SAE International.
As of 2026, the current version is (or newer revisions), which provides updated procedures for ensuring that antennas—such as biconical, log-periodic, horn, and monopoles—provide precise measurements in a shielded room environment.

Searching for a SAE ARP 958 (Electromagnetic Interference Measurement Antennas; Standard Calibration Method) can be tricky because SAE International is a professional organization that typically charges for its standards to fund their development and maintenance.
The (Aerospace Recommended Practice) is a crucial technical standard used for the calibration of antennas used in Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) testing. What is SAE ARP 958? SAE ARP 958 is an indispensable document for
While its original intent was focused on mobile radios used in aerospace and automotive contexts, the standard has become a foundational reference for validating any RF test site. Its primary function is to define a method for measuring .
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. Open-Source Educational Resources As of 2026, the current version is (or
SAE standards are copyrighted and generally not available for free. You can find official copies and detailed technical summaries through the following channels:
For those trying to understand the mathematical concepts behind the Three-Antenna Method, academic papers and tutorials on EMC testing are widely available for free on platforms like ResearchGate or university repositories. These resources explain the underlying physics and formulas used in ARP958 without infringing on SAE's proprietary text. Conclusion
