Description

SA3602A Automatic Distortion meter, with technology of single-chip microcomputer control and nixietube display and combining the analog and digital technology, is used to measure the distortion, frequency and voltage RMS of sine wave frequency range in 20Hz to 20kHz and voltage range in 100mVrms to 300Vrms, and the minimum distortion measurement can be up to 0.01%, and is a high performance intelligent instrument with low price.

 

This instrument has functions of range auto-switching; 4-bit digital display, decimal point automatic location; unit manual-switching; voltage and distortion measurement manual-switching display, voltage units displaying as the form of V, mV or dBm, distortion units displaying as the form of % or dB and visual to display and easy to use. It can be widely used in schools, factories, laboratories and research institutes.

The instrument can be used to observe the Lissajous’ Figures composed by output signal through using X / Y function.
