This page of T & M World compares Spectrum Analyzer vs Network Analyzer and mentions comparison between Spectrum Analyzer and Network Analyzer in tabular form.
| Spectrum Analyzer | Network Analyzer |
|---|---|
| It is used to measure signal characteristics e.g. carrier power level, sidebands, harmonics, phase noise, etc. on unknown signals. | It is used to measure known signals of components, circuits, devices and sub-assemblies. |
| Provides less accuracy in measurement. | Provides high accuracy in measurement. |
| It uses higher IF bandwidth filters. | It uses lower IF bandwidth filters. |
| It is easy to use marker for measurement on display but it is difficult to interpret results. | It is hard to use marker for measurement on display but it is easy to interpret results. |
| Can demodulate and measure complex signals. | It consists pf source and receiver for measurement. |
| They house receivers only with single channel. | They house both source and receiver and used for reflection and transmission coefficient measurement requiring both reference input, reflected and transmitted signals. |
| It can be used for scalar component measurements only. They are not used for phase measurements. | It can be used for amplitude and phase measurements. |
| It does not have advanced error correction. | It uses advanced error correction. |
