Hi everyone,
I am wondering if anyone has tried to measure two signals with a delay difference of less than 1ns? I am working on a high speed digital circuit right now and the delay from the rise of CLK to the rise of output is less than 400ps.
Ideally, I would like to see this on an oscilloscope. However as I checked the best oscilloscope I can get has a sampling rate of 20GSa/s, which is 50ps per point. I think in order to construct a meaningful graph, it will require at least couple hundred samples(dots) on the oscilloscope to show the two waveforms?
Has anyone encountered similar problem before? How do you solve/toggle this problem? Any tips and suggestion is very appreciated.
Thanks,
Pierce
