CPRI RF measurement, for in-the-field testing

September 21, 2015 // By Graham Prophet
Anritsu has introduced a CPRI-based test option to simplify remote-radio-head (RRH) measurements; field engineers and technicians can conduct RF tests on RRH at ground level to reduce base station maintenance and installation costs

The CPRI (Common Public Radio Interface) RF Measurement option for Anrittsu’s BTS Master handheld base station analyser family can reduce the operational expense (OpEx) associated with troubleshooting interference at base stations. Featuring optimum sweep speed and unique test capabilities, the BTS Master-based CPRI RF measurement test set allows field engineers and technicians to conduct accurate RF measurements on Remote Radio Heads (RRHs) while remaining at ground level, eliminating the considerable expense and time associated with calling a tower crew to conduct interference measurements.

With the new option installed, the BTS Master can conduct RF measurements over the fibre optic CPRI link connecting the baseband unit (BBU) and RRH. To simplify configuring the CPRI link for RF measurements, Anritsu has developed preconfigured radio setups and an auto detect function in the option.

A sweep speed 10x faster than other solutions in its class allows the BTS Master-based CPRI RF measurement test set to capture bursty signals missed by alternative methods. Complementing the sweep speed are two unique features – the ability to tune and pan on a displayed signal, and to zoom into a particular area of interest. Faster sweep speeds and more detailed signal analysis allow field engineers and technicians to more efficiently locate the sources of interference and PIM. Users can conduct CPRI Spectrum and CPRI Spectrogram measurements with the test set.

The CPRI RF option expands the comprehensive measurement capability of the BTS Master family; the handheld base station analysers in the range have been specifically developed to support 2G/3G/4G wireless networks, and feature over 30 analysis functions in one instrument
