The handheld unit utilizes the Samsung Q1 Ultra tablet UMPC as an interface in conjunction with Berkeley’s precision receiver technology for complete spectrum analysis as well as WiMAX packet demodulation. The receiver sweeps the 2.0 - 5.9 GHz spectrums to within +1.5 dB accuracy. RF engineers can see the whole wireless network picture.
Features include power triggers, peak hold/search, markers, multiple waveform traces and more. The optional DF (Direction Finding) Antenna allows engineers to pinpoint sources of WiMAX interference, rogue base stations and even nearby hackers. An internal 12-channel/satellite GPS receiver allows for geo-coded site surveys using optional mapping software.
Rohde & Schwarz, meanwhile, has launched their R&S TSMW, a universal mobile radio scanner that features two integrated receivers with WiMAX functionality. The scanner delivers accurate results across the entire high measurement bandwidth because individual blocks can be filtered out allowing network operators to perform drive tests for setting up and optimizing WiMAX networks.
Rohde & Schwarz’s R&S TSMW has a frequency range of 30MHz to 6GHz and measurement bandwidth of 20MHz per receiver. It’s suitable for both mobile and stationary applications and detects signals with a sensitivity that is considerably below the noise level (noise figure of 7dB at 3.5GHz). This makes it possible not only to check neighborhood information for a base station, but also to locate interference signals from other base stations.
Rohde & Schwarz has added a new suite of application firmware that runs on the R&S FSQ and R&S FSG signal analyzers for testing 802.16e-2005 WiMAX. The FSQ-K94 firmware can be used for testing semiconductor components such as WiMAX MIMO chipsets, amplifiers and mixers, as well as complete products.
