Anritsu introduces PIM over CPRI software for its BTS Master handheld base station analysers that allow passive intermodulation (PIM) measurements to be made from the ground for the first time. By eliminating the need for installation and maintenance crews to climb the tower to test for PIM, the new BTS Master-based solution is a more cost- and time-efficient tool for ensuring optimal operation of wireless networks.

PIM over CPRI is a patented PIM measurement technique that uses live traffic, unlike traditional RF PIM measurements that require a site be turned down for tests to be conducted. All that is required for PIM over CPRI to be performed are two Small Form-factor Pluggable (SFP) transceivers and an optical tap. Another benefit is that no component in the transmission line needs to be disconnected, eliminating the possibility of PIM being introduced into the system due to elements such as metal shavings or improperly torqued connectors.

If the BTS Master with PIM over CPRI capability detects PIM at the ground level, the network operator can dispatch a tower crew to perform a traditional RF PIM measurement using the Anritsu PIM Master MW82119B battery-operated, high power, portable passive intermodulation analyser. For rooftop base stations where PIM is detected, the Anritsu PIM Hunter test probe can be used. If the system is PIM-free, the network operator can conduct other tests to locate issues affecting the site, such as interference.
