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.
