VIAVI RFoCPRI PIM Analysis with OneAdvisor 800 Wireless


Traditional passive intermodulation (PIM) isolation methods involve disconnecting a radio from its feedline and setting a dedicated tone generator to perform PIM analysis through the operating frequency band of the radio. However, dedicated tone generators have several disadvantages like their size and cost, as well as the limitation of being frequency-dependent. In contrast, the VIAVI OneAdvisor 800 performs PIM detection from the ground through RFoCPRI, performing RF analysis of the uplink while the cell site is in service.
