FSIQ26 Rohde & Schwarz Spectrum Analyzer


The FSIQ26 is a 26.5 GHz Spectrum Analyzer from Rohde & Schwarz. A spectrum analyzer measures the power of spectrums of known and unknown signals. Spectrum analyzers collect information such as the magnitude of an input signal compared to its frequency. As a frequency analyzer, spectrum analyzers’ main use is to document and analyze electrical input signals as well as spectral compositions of other signals.
