In 2010, Anritsu announced that it had invented and succeeded in developing a patented technology that pinpoints PIM faults called Distance-to-PIM™ (DTP). DTP shows the location for PIM problems within the antenna system, as well as distance to external PIM sources outside the antenna system. This was an incredible step forward in improving the quality of information received from the on-site PIM test. But one problem still remained for pinpointing external PIM beyond the antenna, DTP could tell you how far away from the antenna the PIM source was located, but not the angle. If the antenna had a 120 degree beamwidth, the PIM could be located anywhere along the 120 degree arc at the distance measured by DTP.
Anritsu is now pleased to announce their new solution with the introduction of PIM Hunter, a patent-pending technology that allows a test technician to pinpoint the location of external PIM beyond the antenna. By walking along the arc of the DTP distance from the antenna with PIM Hunter™, the technician can pinpoint the source of the PIM typically within a few centimeters.
