The Marconi IFR Aeroflex FM/AM1600CSA is a cellular protocol analyzer engineered for in-depth measurement and compliance testing of dual-band mobile communication systems. It delivers protocol analysis, RF signal generation, and modulation characterization across 250 kHz to 1 GHz, supporting TDMA/DAMPS, AMPS, NAMPS, and GSM standards. The instrument combines a full-duplex signal generator, real-time spectrum analyzer, digitized oscilloscope, and integrated metering suite in a single platform for field and laboratory deployment.
