Wave analyzer and Harmonic distortion analyzer

Wave analyzer

Harmonic distortion analyzer

1. These are designed to measure the relative amplitude of each harmonic or fundamental components separately. 2.They indicate the amplitude of single frequency component 3.These are tuned to measure amplitude of one frequency component with in a range of 10Hz to 40MHz 4.These are also known as frequency selective voltmeters, selective level voltmeters, carrier frequency voltmeters 5. These are used with a set of tuned filters and a voltmeter. 6. Wave analyzers provide very high frequency resolution. 7.These can be used for electrical measurements, sound ,vibration ,noise measurement in industries

1. These are designed to measure the total harmonic content present in a distorted or complex wave form. 2. They do not indicate the amplitude of single frequency component 3.These can be operated with in a band of 5Hz to 1 MHz frequency 4.It is general know as distortion analyzer 5. These can be used along with a frequency generator. 6. They measure quantitative harmonic distortions very accurately.7. 7.These can be used to measure frequency stability and spectral purity of signal sources
