There is a difference between logic analyzer and linear spectrum analyzer
| Logic analyzer | Spectrum analyzer |
|---|---|
| It is used for the trouble-shooting of digital systems. | It is used for the frequency domain analyzer of various systems. |
| Logic analyzer can be only used for digital systems analysis. | Spectrum analyzer can be used to analyses any real time systems. |
| The logic analyzer is compatible with different logic families like TTL, CMOS, NMOS. | SSpectrum analyzer is not compatible with different logic families. |
| They are of two types logic timing analyzer and logic state. | They are of scanning and non scanning type. |
| In logic analyzer at a time a number of waveform can be observed. | In Spectrum analyzer at a time only a single spectrum can be observed. |
| In case of logic analyzer the number of samples that are to be displayed can be adjusted as per the choice of user. | The span of the spectrum is adjusted as per the choice of user. |
