Using a Wave Analyzer To measure Harmonic Distortion

[stanleystan]

How do you use a Wave Analyzer to measure Harmonic Distortion?

What other kinds of test or measurements can you use a Wave Analyzer for? to do test or measurements for what kind of circuits?

 

[D.A.(Tony)Stewart]

Spectrum Analyzers are useful for Bode Plots with synchronous FM to sweep similar to a Network Analyzer but less powerful.

For RF it is used for THD, IMD, 3rd Order Intercept on power output distortion, SNR, CNR, FM deviation, Spectral bandwidth of any modulation, linear or log-log display, Phase noise, output power vs input variable, Hum detection, PSU noise detection, etc etc.

With a wave analyser (audio spectrum analyser), you can measure the amplitude of each harmonic and then mathematically sum them to get a total figure.
