The Rohde & Schwarz FSP3 is a 9 kHz to 3 GHz spectrum analyzer engineered for signal characterization across development and production environments. It delivers exceptional sensitivity with a displayed average noise level of -155 dBm (1 Hz) and >100 dB dynamic range, enabling detection of weak signals in complex RF environments. The instrument combines fast sweep performance—2.5 ms minimum in frequency domain—with flexible measurement automation for rapid design validation and compliance testing.
