Method of calibrating a measurement instrument for determining direction and distance to a source of passive intermodulation (PIM)
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.
Abstract(Chinese):

校准被配置为使用定向天线发送射频（RF）信号和接收PIM信号的无源互调（PIM）测量装置的方法包括布置连接到定向天线的PIM测量装置，使得定向天线被配置为发送 RF信号具有基本上无阻碍的视轴，发射RF信号，并使用PIM测量装置获得PIM测量。 然后可以基于获得的PIM测量来校准PIM测量装置。
