Anritsu has introduced the IQ Fiber Master MT2780A multi-port CPRI based RF and PIM analyzer that reduces the test costs and time by providing a single instrument to conduct RF interference measurement and PIM troubleshooting on LTE-based systems using CPRI front haul infrastructure. MT2780A allows the field engineers, field technicians, and third-party contractors to leverage patented PIM over CPRI and RF over CPRI measurement capability that allows tests to be conducted on the ground, this significantly reduces tower climbs.


MT2780A is the first instrument to perform true PIM analysis over fiber and present RFspectrum results derived from IQ data, it allows the field engineers and technicians to scan the uplink RF signals of a remote radio head (RRH) for in-band interference, at the same time they can also conduct PIM over CPRI measurements. The users can view a radio’s uplink spectrum for interface troubleshooting and the device can measure PIM over CPRI with four SFP inputs, it also can compare multiple brands and sectors.


The analysis results of the IQ Fiber master can provide a full PIM diagnosis like the presence of PIM whether it is internal or external, and the distance to PIM. The Transmitter that contributed the most PIM is displayed by the unique and proprietary PIM heatmap which collectively. The IQ fiber Master can be installed at cell sites to conduct long term PIM over CPRI measurements and provide analytical information. 


The real-world testing can be accurate and with no system downtime because the measurements are performed on live-cell tower traffic signals since they are delivered from baseband IQ data. The IQ Fiber Master can be used to measure on any frequency RRH, or combination of frequencies of the RRH, providing a very cost-effective solution.


Features of the IQ Fiber Master MT2780A

  • RF over CPRI spectrum for interference measurements
  • PIM over CPRI for any frequency PIM measurements
  • PIM analytics for long-term PIM monitoring
  • Determine if KPIs are being affected by interference or PIM
  • PIM location (DTP)
  • 4 SFP ports
  • 4x4 MIMO support
  • CPRI line-rate 1 – 8 support
  • Support all Tier 1 LTE base station radio manufacturers
  • Up to 12 AxC traces simultaneously for multiple sectors/carriers
  • Uses MX280020A control software


More technical information can be found in the MT2780A datasheet linked at the bottom of this page and in the IQ Fiber Master MT2780A Product page.


All PIM-related problems, such as intermittent PIM occurring on specific days and times or changes in PIM due to base station load during the day, can be measured in this configuration. The IQ fiber master also serves as a band-less PIM testing solution that can be a carrier’s first test tool when identifying an interference problem and its location.


All LTE bands are supported by IQ Fiber Master MT2780A. Extremely compact and lightweight, it weighs only 1 kg (2.2 lbs.) and measures 185 mm x 133 mm x 55 mm (2.1 in x 7.3 in x 5.2 in), so it fits in the palm of the user’s hand.
