THD% measurements

Post by teemumm » Sun May 18, 2014 1:44 pm

I have been looking for a device to measure THD% of audio signals. I think I can measure THD of such signals with any PicoScope, but I'm wondering what kind of precision I could get with 8-bit resolution. 2204A includes also 12-bit enhanced resolution. Does this enhanced 12-bit resolution also apply to spectrum analysis of the signal?

Hi teemumm,

The 12 bit enhance does not apply to the spectrum analysis.

And therefore the 2204a is not suitable for audio measurements.
