What is a spectrum analyzer?
What will be an ideal response?
A spectrum analyzer scans the radio frequency spectrum (2.4 GHz or 5 GHz for WLANs) and can locate potential sources of interference. Spectrum analyzers are passive receivers: they do not make any changes to the signal but instead display it in a way that makes it easy to analyze. Spectrum analyzers usually display the raw and unprocessed signal information such as frequency, voltage, power, period, and the shape of the RF "wave." The most common spectrum analyzer measurements are modulation, distortion, and noise.
