Rohde and Schwarz FSV40-N Signal & Spectrum Analyzer, 40 GHz

The Rohde & Schwarz FSV40-N is a signal and spectrum analyzer covering 9 kHz to 40 GHz, purpose-built for RF characterization across demanding applications. It delivers measurement speed - over 500 sweeps/second in manual operation, up to 1000 sweeps/second remotely - with exceptional sensitivity and dynamic range. The fully digital back-end ensures high measurement accuracy and repeatability.
