The FSH3 is a 3 GHz spectrum analyzer from Rohde & Schwarz. A spectrum analyzer measures the spectral power of known and unknown signals. It collects information such as the amplitude of the input signal relative to its frequency. As a frequency analyzer, the primary use of a spectrum analyzer is to record and analyze the spectral components of electrical input signals and other signals.
