Passive Intermodulation (PIM) Testers
Identifying Hidden Intermodulation Distortion in Passive RF Components
Passive intermodulation (PIM) testers identify unwanted intermodulation distortion generated by passive RF components under multi-carrier load — a critical test for cellular base stations, DAS systems, and any shared RF infrastructure where PIM can silently degrade network performance.
This range spans desktop bench testers for component qualification and production QC, cabinet/rack systems for R&D and production-line testing, and portable field testers for installed antenna systems and base stations, with specialized POI, blind, and heterodyne multi-order variants for advanced characterisation work.
Where This Fits
PIM sits apart from the rest of this page — it's not a product-level EMC test, but a check on the RF network infrastructure itself (connectors, cables, antenna feeds) for a specific fault mode: a loose or corroded junction generating unwanted intermodulation products when strong signals pass through it.
This matters most if you're supplying or maintaining telecom infrastructure, base stations, or antenna systems, rather than running EMC compliance tests on a product — a PIM tester catches a class of field problem that no amount of conventional EMC testing elsewhere on this page would reveal.
