Hello Chris
The measuring software I use is 'Arta'.
My signal generator comes from my laptop (which Arta manipulates).
The microphone used is the Behringer 8000.
Arta measures the purity of the signal going out (from the computer), against the DUT (device under testing, which is my entire system).
Since I am testing my entire system, Arta is testing the final output.
The blue trace is second order harmonic distortion, with the red trace third order distortion.
In order for me to test the pre amp on it's own, or the amp, I would need to build a 'measuring box'. I am only concerned with the entire system, which is why I've never bothered to build 'the box'.
