  • The differences arise in the measurements made and how they are made. While a spectrum analyzer analyzes an applied signal, a network analyzer creates a signal and characterizes the devices that receive it. Spectrum analyzer is an instrument that is used for the analysis of the frequency spectrum of the input signal is known as a spectrum analyzer. It uses frequency domain representation of the RF signals in order to show the relative amplitude level of the signal at various frequencies within a particular range. A wave analyzer is an instrument designed to measure relative amplitudes of single frequency components in a complex waveform. Basically, a wave instrument acts as a frequency selective voltmeter which is tuned to the frequency of one signal while rejecting all other signal components.
