The current standard of PIM testing offers a well-known system
of two primary carriers and a calculated PIM frequency, which is
monitored via a spectrum analyzer. This provides a measurement
of the overall linearity of the antenna system and the surrounding
environment.
The Distance-to-PIM test is simple, immediate, and accurate. DTP informs the technician of the distance and magnitude of all the PIM sources simultaneously, both inside the antenna system and beyond the antenna.
