The Anritsu MS2850A is a high-performance spectrum and signal analyzer engineered for RF and microwave measurements in 5G, satellite, and advanced wireless communication systems. It combines wideband signal capture with real-time FFT analysis, delivering exceptional dynamic range and phase linearity across frequencies up to 44.5 GHz. The instrument captures and replays waveform data for time-varying frequency and phase analysis, supporting complex multi-carrier signal characterization.
