These analysers measure RRH performance from the ground eliminating tower climbs

A common public radio interface (CPRI) RF measurement option that is claimed to cut time and costs involved with testing remote radio heads (RRHs) on 4G networks has been unveiled by test and measurement company Anritsu.

The company has implemented CPRI RF measurement capability in its E series of Site Master, Spectrum Master and Cell Master handheld field analysers. This reduces network operational expenditure by letting wireless carrier engineers, identify interference sources on the radio uplink at ground level which reduces the need for tower climbing crews.

With the CPRI RF measurement option installed, the E series analysers provide users with a number of features when installing, maintaining and optimising wireless networks. Anritsu says its sweep speed is faster than other solutions and a spectrum/spectrogram tune and zoom function allows users to zoom into an area of interest on a displayed signal to closely examine interfering signals and better identify their origin.

An auto detect function is also designed into the CPRI RF measurement option that automatically configures the CPRI link to minimise set up time and potential errors.
