The Rohde & Schwarz CMTA54 Radiocommunication Analyzer is an integrated test platform that combines signal generation and analysis in a single instrument. Designed for validation of mobile devices, wireless modules, and communication networks, it delivers the functional density required for comprehensive RF characterization across multiple standards and modulation schemes. This dual-capability architecture eliminates the need for separate generators and analyzers, streamlining test workflows while maintaining measurement accuracy and repeatability.
Technical Specifications
The CMTA54 supports advanced signal generation with configurable modulation formats and arbitrary waveform capabilities. Signal analysis includes demodulation, RF power measurement, signal quality assessment, protocol-specific analysis, and spectral characterization. Measurements encompass average power, peak power, burst power, error vector magnitude (EVM), modulation error ratio (MER), signal-to-noise ratio (SNR), adjacent channel power ratio (ACPR), and occupied bandwidth. Spectrum analysis features include selectable resolution bandwidth, video bandwidth control, variable sweep timing, and wide dynamic range performance.
