- Anritsu equips its BTS Master handheld base station analyzers with PIM-Over-CPRI measurement capability.
- The BTS Master MT8220T and MT822xB base station analyzers enable passive intermodulation (PIM) measurements from the ground using the PIM-over-CPRI measurement software.
- Network installation and maintenance technicians no longer have to climb up a tower to perform PIM measurements.
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 analyzer 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 portable passive intermodulation analyzer. 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.
The BTS Master handheld base station analyzers, with touch screen GUI, combine 30 analyzers into one to meet virtually every measurement need at a base station. It includes 20 MHz bandwidth modulation, a vector signal generator with frequency coverage of 400 MHz to 6 GHz for DAS and receiver testing, and sweep modes for interference hunting and analysis.
