is for use when measuring a source 1 meter (m) from the antenna in a shielded room, the typical distance used in military EMC testing. The standard covers the calibration of various antennas, including biconical, horn, monopole, and small loop antennas.
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.
💡 If you are testing hardware for the Department of Defense or commercial aviation, your antenna calibration must likely follow SAE ARP 958 to ensure the results are legally and technically valid. If you'd like, I can help you: sae arp 958pdf free
Armed with the SAE ARP 958 PDF, Aidan's team was able to fine-tune their radar system's EMI emissions and ensure it met all the necessary standards. They conducted rigorous testing, adhering strictly to the document's guidelines. The results were satisfactory, and they were able to confidently move forward with the project.
SAE ARP958 remains a cornerstone document for RF engineering. By defining the methodology for measuring site attenuation, it ensures the integrity of the invisible "lab" in which wireless technology is tested. For those requiring the document, the safest and most professional route is to purchase it directly from SAE International or access it through an institutional library to ensure you are working with an authentic, up-to-date copy. is for use when measuring a source 1

The document presents a technique to determine for antennas used primarily in performing measurements. The calibration method is based on measuring a source 1 m from the antenna in a shield room. However, it is important to note that the influence of the shield room on the measured field strength is not considered. Essentially, ARP958 answers a critical question: how do
Many large engineering firms, universities, and research institutions maintain subscriptions to standards databases. If you are affiliated with such an organization, you may have free access through their internal technical library or standards portal.
Since its original release in 1968 (which only covered log-spiral antennas), the document has evolved through several key revisions: Revision A (1992):
