Rohde & Schwarz FSP40 9KHz to 40GHz Spectrum Analyzer

The Rohde & Schwarz FSP40 is a spectrum analyzer covering 9 kHz to 40 GHz, engineered for signal analysis, component testing, and EMC investigations. Built on super-heterodyne receiver architecture, it delivers measurement uncertainty of 0.5 dB with linearity error below 0.2 dB down to -70 dB. The instrument combines fast acquisition - minimum sweep times of 2.5 ms in frequency domain and 1 µs in time domain - with versatile detection and filtering for demanding RF characterization.
