AUDIO SWEEPER 7116C
7116C provides pure sine wave with very low total harmonic distortion. (approx. 0.1% THD ). The total harmonic distortion of 7116C consists of 2nd Harmonic component only and nearly without higher order harmonic components. So, 7116C is very suitable to test the sound quality ( spurious noise inspection ) of all kinds of loudspeaker, headphone, receivers, piezo, speakers system…etc.
The frequency produced by 7116C is more stable than the ordinary beat frequency oscillator produced. and the sine wave provided by 7116C is purer than the ordinary function generator. Therefore, 7116C has both advantages of low distortion and high stability. do not use the ordinary function generator to test the spurious noise ( rattle and buzz ) of loudspeaker, loudspeaker, receiver, etc.… Because user will easily neglect the prohibited spurious noise caused originally from the high order distortion component of the function generator.
