Wave Analyser is an instrument designed to measure the relative amplitude of single frequency components, in complex waveform. It acts as a frequency selective voltmeter, which is tuned to the frequency of one signal, while rejecting all other signal components. The desired frequency is selected by a frequency calibrated dial to the point of maximum amplitude. Depending upon the frquency ranges used, there are two types of wave analyser.
Frequency Selective Wave Analyser:
A frequency Selective Wave Analyser is used for measurments in the audio frequency ranges between 20 Hz to 20 KHz. The analyser has a filter section with a very narrow pass band that can be tuned to the frequency of interest.
Heterodyne Wave Analyser:
For frequency measurements in the MHz range, a heterodyne wave analyser is used. It is mostly suited to the higher frequency. In this wave analyser the input signal to be produce a higher IF frequency. Operating frequency range of this instrument is from 10 KHz to 18 MHz.
(i) The noise sources and vibrations is first identified by wave analysers before it can be reduced.
(ii) The harmonic distortion of an amplifier can readily be measured.
(iii) It is applicable in the fields of electrical, sound and vibration measurements.
(iv) The noise sources and vibrations is first identified, before it can be reduced by a wave analyser.
(v) A fine spectrum analysis with a wave analyser shows various discrete frequencies.
