Instrumentation designed to establish passive intermodulation (PIM) sources in cable and antenna programs typically incorporates cable sweep performance. This built-in method permits technicians to evaluate each the linearity of the system and its frequency response traits utilizing a single check setup. For instance, a technician may use this tools to confirm {that a} newly put in mobile antenna cable displays minimal PIM whereas concurrently confirming it meets return loss specs throughout the operational frequency band.

Using mixed PIM and cable sweep testing affords a number of benefits. It streamlines the testing course of, decreasing the time required for web site certification and troubleshooting. This functionality additionally supplies a extra full image of system well being, enabling the identification of points that is likely to be missed by performing PIM and cable sweep checks independently. Traditionally, separate devices have been required, making the mixed performance a major development in effectivity and accuracy.
