The Rohde & Schwarz FSW13 is a high-performance signal and spectrum analyzer engineered for demanding RF measurement tasks from 2 Hz to 13.6 GHz. It delivers superior dynamic range, low noise floor, and exceptional phase noise performance for precise characterization of complex signals. The instrument combines DC and AC coupling modes, configurable real-time analysis bandwidth up to 512 MHz, and measurement uncertainty under 0.04 dB at 8 GHz—making it ideal for component verification, signal development, and laboratory-grade spectral analysis.
