What is PIM testing?

PIM testing stands for Passive Intermodulation testing, which is a process used to detect and measure intermodulation distortion in passive radio frequency (RF) components such as cables, connectors, and antennas. This type of testing is crucial in wireless communication systems because PIM can cause interference, reduce network performance, and degrade signal quality. By identifying sources of PIM, technicians can ensure that equipment meets industry standards and operates efficiently, preventing costly downtime and service issues.
