1. A method, comprising:
causing a first plurality of radio frequency (RF) signals to be transmitted via a plurality of simultaneous beams of an antenna system in a plurality of different directions, wherein the plurality of simultaneous beams is configured at different frequencies directed at the plurality of different directions;
responsive to transmission of the first plurality of RF signals, monitoring a second plurality of RF signals that are received by the antenna system to detect an interference signal that originates from a first passive intermodulation (PIM) source; and
determining a location of the first PIM source based on the monitoring of the second plurality of RF signals, wherein the plurality of simultaneous beams comprises test signals adapted for detecting passive intermodulation (PIM).
