The Rohde & Schwarz FSV4 is a spectrum and signal analyzer delivering measurement capability from 10 Hz to 4 GHz with 0.01 Hz frequency resolution. Built for speed and precision, it combines low displayed average noise levels (–155 dBm at 1 GHz in 1 Hz bandwidth) with input attenuation from 0 dB to 60 dB in 1 dB steps. The instrument achieves level measurement uncertainty of 0.4 dB up to 7 GHz and third-order intercept performance of +15 dBm typical across its operating range. Its 160 MHz optional analysis bandwidth supports modern signal characterization, while resolution bandwidths extend from 100 Hz to 20 MHz (40 MHz with options). Phase noise performance reaches –110 dBc (1 Hz) at 10 kHz offset. An intuitive touchscreen interface and compact form factor enable rapid deployment in lab, production, and field environments.
