Calculating time difference between two signals

Post by RobynZ » Mon Nov 07, 2016 1:04 pm

Hello,

i want to measure the time between two signals.
The first signal (A) is a rectangle as an input into my measurement system.
The second signal (B) is the "reaction" of my measurement system at the output.
I want to measure the time delay between A & B.
Is there a better solution than doing it "by hand" with the time ruler?

Thanks a lot.

We currently do not have the ability to perform calculations and measurements between channels, although there is a feature request with the development team for this.

Is there an update on this issue? When is it going to be developed?
We use this kind of function on our cheap oscilloscopes and expected to see this simple feature on this PicoScopes too.
Thank you.

This has not been added as yet.

What specific functionality are you looking for ? Is it just the time between events on channels ?

I was also looking for the ability to measure the time from an edge on channel A to an edge on channel B, and was disappointed to find that such a basic feature was missing. More specifically, it's the ability to gather stats on the time that would be useful, for example to evaluate the jitter of a PLL. Picotech, I'd really urge you to add this feature to the software.

This is still on the new feature list, but hasn't made it into the development cycle yet. Recently the focus has been on the the introduction of the Deep Measure feature in 6.13, for cycle based measurements.

For measuring the jitter of a pll have you tried using persistence mode ?
