The is no way to de-embed the effect of the ADC other than using a "reference DAC"...
The SU-10 sits at the very top of ASR's SINAD table
Besides the DC filter, the ADC also has effects coming from the anti-aliasaing filter and these effects are magnitude and phase changes near fs/2 (so one should choose a steep linear-phase filter) and a passband ripple which is small but not irrelevant.
Yes. But these will be 'applied' equally to all comparison files (which have been through the DA/AD chain). If large differences in nulls between comparison files exist, then it must be down soley to the DACs.
Assuming, of course, that the R and C files are all correctly matched. I'm confident of this because of the very little variability between samples from the same DAC.
