The Rohde & Schwarz FSP13 is a high-performance spectrum analyzer delivering RF and microwave measurements from 9 kHz to 13 GHz. Built for development, production, and research environments, it combines exceptional sensitivity with measurement accuracy and fast acquisition speeds. The FSP13 excels in detecting weak signals with a displayed average noise level of -155 dBm at 1 Hz resolution bandwidth, while maintaining phase noise performance of -113 dBc/Hz at 10 kHz offset and -145 dBc/Hz at 10 MHz offset. Total measurement uncertainty reaches 0.5 dB across its operating range, with intermodulation-free dynamic range of 100 dB.
