The MS2721B is a 7.1 GHz Spectrum Analyzer from Anritsu. 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.​
