SIQMA SC2820 CPRI Analyser

CPRI Sniffer and Analyser

CPRI testing has come a long way. In the past, all signal processing units of the base station were located at ground level instead of the top near the antenna which leads to path loss due to long RF cabling. Nowadays, in order to prevent the loss due to long RF cabling, the processing unit has been divided into a preprocessing unit at the top of the mast, the RRU (Remote Radio Unit) and the BBU (Base Band Unit) located on the ground surface. The digital CPRI link is used to connect the RF unit at the top of the tower to the BBU located at the bottom. Besides having an advantage of power efficiency, it leads to other issues associated to maintenance such as one has to climb up the mast in order to see the uplink spectrum by connecting the signal analyser via RF cables.

The SC2810 or SC2820 CPRI analyzer provides cell site installers, maintenance operations and troubleshooters with a convenient tool that can be used on a live site. A low loss optical splitter is inserted in series with the existing RRU to BBU optical cable, resulting in minimal disruption to the sites operation. Splitters can be left on site if multiple visits are required.

CPRI data can be collected and stored or viewed live. Live data is presented to the user on Windows GUI or streamed out via a front panel RF connector for analysis with an optional spectrum analyser.
