Berkeley Varitronics Systems, Inc. unveils its YellowFin calibrated, demodulating WiMAX test receiver that is capable of complete spectrum analysis as well as WiMAX packet demodulation. The receiver sweeps 2 to 5.9 GHz to within 1.5 dB accuracy and it includes RSSI measurements for Cell-ID and segment, multipath analysis and CINR (carrier-to-interference-plus-noise-ratios) on a preamble basis. An internal 12-channel/satellite GPS receiver allows for geo-coded WiMAX site surveys and drive studies using optional mapping software. The device's GUI is Samsung's Q1 Tablet UMPC that includes an Intel core solo 1.3 GHz processor and a 7? WSVGA touch screen.
