Anritsu continues to address the emerging test requirements associated with 4G base stations with the introduction of OBSAI RF Analyser software to complement the existing CPRI RF analysis capability of its handheld analysers. With the software installed in the handheld analysers, wireless carrier engineers, technicians and contractors responsible for solving interference and PIM issues can identify interference sources on the radio uplink from the ground, thereby lowering OpEx (operational expense) by reducing the use of tower climbing crews.

The CPRI/OBSAI Analyser allows users to conduct RF-based measurements over a fibre-optic link to locate interference affecting an RF module (RFM) by tapping into the fibre link between the RFM and baseband module (BBM). The Anritsu handheld instruments will decode the CPRI/OBSAI protocol IQ data and convert it to RF data. Bandwidths of 5, 10, 15 and 20 MHz are supported.

Among the measurements available with the new option is a spectrum mode that can be used to test the link in real time. Additionally, field technicians and engineers can monitor for intermittent interference over a specifiable recording time using the Spectrogram mode. All CPRI & OBSAI Analyser measurement functions can be performed from ground level. After testing and reviewing the results, a determination can be made on the need for a tower crew.

The software can be integrated into the latest BTS Master and Site Master models. It supports the most recent radios from Ericsson, Nokia/ALu, Huawei and Samsung.
