Correct, I'm working on DAC output as well. None of this stuff is easy. We are trying to measure a DAC output using ADCs, to do that requires an ADC that has lower clock jitter than the DAC we are trying to measure, this is NOT easy to do! The off the shelf audio analyzers are nowhere near close enough. So as with everything else related to this I have to make my own. It's not easy and it's not cheap.

 

I have something up and running which still needs a lot of more work to lower ADC jitter and prevent external signals from getting in, but it DOES actually get signal through. Maybe within the next week I'll try it with real audio DACs and see how things are at this point in the development process.

 

My ultimate goal is to show the whole process from ground plane noise, to DAC clock jitter to DAC analog output.

 

I WILL get there, but it is going to take a significant amount of time to get there.

great work John!

a big step in the right direction.

Hey I trust my ears, but as an engineer I greatly appreciate the effort to try to understand what is going on.

 

Hypothesis, experimental data......all good stuff on the road to understanding.
