WiMAX test receiver

Berkeley Varitronics has unveiled what it claims is the world’s first calibrated, demodulating WiMAX test receiver called YellowFin.

It is said to be the only handheld WiMAX tester capable of complete spectrum analysis as well as WiMAX packet demodulatiion.

The receiver sweeps 2.0 to 5.9 GHz to within +1.5 dB accuracy and 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 latest Q1 tablet UMPC that includes an Intel core solo 1.3 GHz processor and 7" WSVGA touch screen.

Features include power triggers, peak hold/search, markers and multiple waveform traces. The optional DF (direction finding) antenna allows engineers to pinpoint sources of WiMAX interference, rogue base stations and even nearby hackers.
