PIM testing: best practices in a nutshell

When it comes to PIM testing, the necessary steps to identify passive intermodulation (PIM) and locate its source are similar to interference hunting. In the end, PIM is an internal source of interference and can have a significant impact on network performance. Before starting with PIM measurements, however, it is recommended to test return loss. The PIM analyzer transmits high power;…
