Can I measure group delay of an Audio ADC or DAC with my UPP / UPV?

Question:

I want to measure the group delay of an audio ADC or DAC. Can I perform such a measurement with the UPP or UPV?

Answer:

Unfortunately this measurement is not possible with UPP as well as with the UPV.

Both Audio Analyzers measure the phase (and deflect the group delay) only between two analog or two digital channels, not between analog and digital or vice versa as it would be necessary for DAC or ADC.
