delay measurements
(OP)
I'm trying to make a device that could measure the time delay between two signals. I have a reference signal of 10MHz and I have another delayed 10MHz signal. I need to make a precise measurement of this delay between two square wave signal which can as small as 0.17ps.
Most of the components that I've seen so far are too slow for this purpose (their rise time is in nano sec...wont have enough time to respond). Do you have any idea of which component can be accurate enough to measure a delay of 0.17ps.
Thank you for help in advance

RE: delay measurements
If analog, waveform, amplitude ?
What kind of resolution and accuracy do you need ?
One device or mass produced ?

RE: delay measurements
Having this two waveforms (more or less square waves coming from two different mosfets) I need to measure the delay between two waveforms. I need to detect the delay as small as 0.17ps, so the precision is a big factor.
One device or mass produced is not a factor
thank you
RE: delay measurements
You're looking to measure to 1.7 ppm, or 170 parts per 100,000,000.
Good luck. It won't be cheap. And ask yourself how you will calibrate and verify it.

Good luck, you'll need it.
