What exactly is Spectrum Analysis? A spectrum display from a spectrum analyzer. Because spectrum analyzers have the capacity to undertake a large variety of measurements, they have become essential instruments for RF design development and test. Without the spectrum analyzer, it would not have been possible to break the elements of a signal or to credibly gauge a circuit’s performance. The spectrum analyzer has two axes – frequency and amplitude - and resembles an oscilloscope in its layout. These are otherwise hard to detect in time domain waveforms. This analyzer is advantageous in understanding the parameters of electronic devices, especially wireless transmitters because the spectral workings of the instrument in terms of signals, distortions, frequency and power can be easily observed. Although the primary signal that is fed into the spectrum analyzer is electrical, it also analyzes the spectral compositions of acoustic waves and light waves through the use of a proper transducer. It is useful to measure the spectrum powers of both the known and unknown signals in an electrical instrument. It does this in the entire range of the instrument’s frequency bandwidth.

The spectrum analyzer is an electronic device that is used for measuring the magnitude of the input signal against the frequency in an instrument. Thus, we give a basic overview of the two devices and their basic mechanism: Before we differentiate a spectrum analyzer and a network analyzer, it is important to understand what these two instruments are, and what function they perform.
