use MSO digital channels to measure phase delay in degrees.

I'm analog channel limited. Would I be able to use the digital channels to measure phase delay among different clock signals? In a way that I'll be able to add a stat badge, limit the population and query the mean of those phase delays? See attached. 

Hi Xiang,

Yes, Phase measurements work just as well with digital signals as they do with analog signals.
I have attached an image of such a measurement.

How is the accuracy of digital channels compared to analog channels. I know it throws out quite a bit of information. It's more like a threshold lo/hi. Do you think using this method is detailed enough if I'm interested in phase delay down to 0.1 degree? 

Hi Xiang,

Looking at your image it looks like you have a signal with 1.5 us period, which is to say, 0.667 MHz. The TPL058 (which is the appropriate logic probe for the MSO4/5/6, which I assume you're using) has a bandwidth of 500 MHz and a maximum sampling rate of 6.25 GS/s.
These specifications exceed your signal and so I expect you to be able to get quite good resolution of the phase measurement.
