RF analysis software identifies interference sources on the ground

ANRITSU OBSAI RF Analyzer software addresses the emerging test requirements associated with 4G base stations by expanding the measurement capability of its handheld analyzers. Software assists in solving interference and PIM issues by identifying interference sources on the radio uplink from the ground, thereby lowering OpEx (Operational Expense) by reducing the use of tower climbing crews. The new OBSAI Analyzer allows users to conduct RF-based measurements over a fiber optic link to locate interference affecting an RF module (RFM) by tapping into the fiber link between the RFM and baseband module (BBM). The Anritsu handheld instruments will decode the OBSAI protocol IQ data and convert it to RF data. http://www.anritsu.com
