That would be because of latency, not jitter.
Jitter would show randomness between cycles of the saw wave.
What you posted does not, the pattern repeats.
So it is not jitter.
It may be caused by the fact that by using different clocks there is a small difference between when the DA is triggered compared to the AD.
Actually, i just discovered that i was not talking about this screenshot.
You don't see repeating cycles on this.
I was refering to the pics here:
test A/D D/A - without personal bias & without ears!
But the story seems the same.
In the DACTEST2.JPG he different waveforms are not the result of jitter.
There is one sample that looks like it might be (3rd track, 5th sample) but you cannot say that with certainty.
You'd need proper tests to find jitter.
