The Rohde & Schwarz CMU200 is a modular radio communication test set engineered for development, production, and maintenance testing of mobile phones and base stations. It supports over 20 cellular and wireless standards—from GSM/GPRS/EDGE through WCDMA/HSPA to CDMA2000, WiMAX, and GPS—with a single platform. The instrument combines vector signal generation and analysis, spectrum measurement, power metering, and audio testing in one chassis, delivering measurement accuracy better than 0.5 dB across a dynamic range exceeding 90 dB.
