The Rohde & Schwarz FSP13 is a high-performance spectrum analyzer covering 9 kHz to 13 GHz, engineered for signal analysis in research, development, and production environments. It delivers measured noise performance with DANL of -155 dBm at 1 Hz and phase noise of -145 dBc/Hz at 10 MHz offset (500 MHz carrier). The instrument combines fast sweep capability—2.5 ms minimum in frequency domain, 1 µs in zero span—with measurement speeds reaching 100 measurements/s via GPIB. Its 100 dB intermodulation-free dynamic range and level measurement uncertainty below 0.5 dB to 3.6 GHz enable precise power and modulation analysis on complex RF signals.
