Wave analyzer:- Wave analyzer is an instrument which is used to measure the magnitude of the various harmonics of a complex waveform. It is an instrument that is designed to measure the relative amplitudes of single frequency components in a complex or distorted waveform.
Wave analyzer need: Signal analysis of both random and periodic signal in the frequency domain is used extensively in electronic and telecommunication. The frequency stability and special purity of signal sources can be measured by the use of these signal analyzers. These signal analyzer can be used along with a frequency generator or a source of white or pseudo-random noise to measure the frequency response of amplifiers, filters or other networks. The operational characteristics of a trans receiver and communication system are determine by measuring various parameters, such as spectral purity of the carrier wave, spectral power distribution of the amplitude or frequency modulated wave, signal distortion and the system signal to noise ratio.
