Abstract
A method of calibrating a passive intermodulation (PIM) measurement device configured to transmit radio frequency (RF) signals and receive PIM signals using a directional antenna includes arranging the PIM measurement device connected to the directional antenna so that the directional antenna is configured to transmit an RF signal having a substantially unobstructed boresight axis, transmitting the RF signal, and obtaining a PIM measurement using the PIM measurement device. The PIM measurement device can then be calibrated based on the obtained PIM measurement.
