The Rohde & Schwarz FSEA is a precision spectrum analyzer operating from 9 Hz to 3.5 GHz, designed for signal characterization across research, quality assurance, and manufacturing environments. It delivers exceptional sensitivity with noise floor performance typically below -174 dBm/Hz (preamplifier ON) and supports dynamic range measurement of small signals in the presence of large interfering signals. The instrument provides configurable resolution bandwidth from 1 Hz to 10 MHz and video bandwidth from 0.1 Hz to 10 MHz, enabling precise separation of closely spaced signals with low phase noise performance.
