Which soundcard ? have very low distortions for fft measurements?

Hi

Which soundcard do have very low distortions (even at high frequencies) for fft distortions measurements ?

Even an old model that I can buy used.

My sinewave generator have only .001% distortion.

Any hints, suggestions are welcome.

Thank

Bye

I really believe that is pushing the limitations of a soundcard more than just a little bit. Many soundcards are capable of providing a very limited fft spectral display, but to attempt using one to measure distortion is a bit of a stretch of the imagination.
