Abstract
Methods and systems for identifying PIM sources for an antenna under test (AUT) are provided, where the AUT is installed in a desired operating environment. The system comprises: a PIM analyser, connected to the AUT for applying first and second RF stimulus signals to an input port of the AUT; and a portable RF emitter, configured to apply a third RF stimulus signal to suspected external PIM sources. The PIM analyser is configured to measuring one or more characteristics of PIM signals received by the AUT generated by the first, second and third RF stimulus signals.
