7116c Audio Sweeper Sunlilab 7116c-60w Suitable To Test Sound Quality

7116C provides a pure sine wave with very low total harmonic distortion. (approx. 0.1% THD ). The total harmonic distortion of 7116C consists of the 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 loudspeakers, headphones, receivers, piezo, speakers systemsa etc
