This standard BS EN IEC 62037-7:2022 Passive RF and microwave devices, intermodulation level measurement is classified in these ICS categories:
33.120.01 Components and accessories in general
33.120.30 RF connectors
33.040.20 Transmission systems
IEC 62037-7:2022 defines test methods for reverse measurement of passive intermodulation (PIM) in systems of RF components deployed in the field. Field PIM measurements can be conducted on RF systems terminated into low PIM loads or on antenna feed systems that broadcast the test signals into the environment.
