The Rohde & Schwarz CMU200 is a universal radio communication tester engineered for mobile device and wireless system validation across development, manufacturing, and research environments. This modular instrument simultaneously generates and analyzes RF signals across 20+ wireless standards, from legacy AMPS and GSM through modern WCDMA, HSPA, and WiMAX. Its four RF connectors deliver signal generation from –130 dBm to +13 dBm and analysis sensitivity to –80 dBm, with measurement accuracy better than 0.5 dB across a dynamic range exceeding 90 dB. The CMU200 executes transmitter and receiver characterization, BER processing, spectrum analysis, modulation quality assessment, and spurious emission measurements at high speed with exceptional repeatability.
