Unlike the EMC Conducted Immunity System (refer to “PMM Cond-IS” documentation) for residential and industrial EUTs (Equipments Under Test) testing, “RF Radiated Immunity” compliance verification as for Standard IEC/EN 61000-4-3 requires a proper shielded and absorber lined testing enclosure where to inject required EM field-strength levels.

Depending on selected testing environment, which could be for example a Semi-Anechoic Chamber (SAC) or a GTEM Cell, some components to be used in the testing chain may significantly change, like Amplifiers or Antennas, while some others can remain the same at least up to 3 GHz, like Generator, Power Meter, Field Probe and Software for automatic management of both Calibration and Testing phases.

A so called “Radiated Immunity System” can still be defined for almost 80% of required components and that’s exactly why NARDA STS Italy has created “PMM Rad-IS” to fulfil core requirements of such kind of testing, leaving an open choice only for Amplifiers and Antennas/GTEMs to be driven as “slave units” while selected case by case according to the various EM field-strength levels.
