There is a difference between logic analyzer and linear 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.
