Signal Analyzers

Introduction: 
 The analysis of any electrical signals  are used in many places as laboratories,         industries, research  and development area etc.

for analysis of its many different instruments can use as,  
- Wave analyzer,
- Harmonic analyzer,
- Spectrum analyzer and Network  analyzer.

- All analyzers, measure the frequency properties of the signals, and for measurement of its use a different techniques.

 Wave analyzer:

- A Wave analyzer The instrument that used to measure the amplitude of each harmonic or fundamental individually is called as the Wave analyzer. 

wave analyzers are used in the low RF range.

It is simplest form of analysis in the frequency domain, it can be done with a set tuned filters and a voltmeter.

Distortion analyzers :

A Distortion analyzers measures the total harmonic distortion content is in input signal with indicating he amplitude and frequency of components.
Distortion analyzer operate over range of 5 HZ to 1 MHz.

Network analyzer:
- A Network analyzer is a instrument that used to measure the S-parameters of a network.

Spectrum analyzer:

- A spectrum analyzer, The instrument which graphically presents an energy distribution of the signal as a function of frequency on the C.R.O. is called Spectrum Analyzer.

This study gives us information about the,

  (i) Band width

 (ii) The types of modulation

 (iii) Spurious signal generation

 (iv) Modulation index

 (v) Attenuation

 (vi) The component levels.
