Measuring signal delay over a long time
Measuring signal delay over a long time
I have a signal with a respons time between 0.1 and 2.0 ms see attachment.
I want to run the trace for 24 hours and see what the min and max delay's are for the signal.
Persistence mode can only show 1 signal not both at the same time.

Re: Measuring signal delay over a long time
Hi Benno,
I don't know what the waveforms look like at a longer Timebase setting, but if they are periodic squarewaves, you can increase the Timebase length to capture one complete cycle, and then use Deep Measure to give you extremely accurate timings for the start of both waveforms. The timings for the measurements of Deep Measure are at the limit of what is measurable with any accuracy, so they are typically to many decimal places. If you are triggering on, say, channel B, then the delay will be just the Start Time on channel A (which you can export to Excel to find the max and min values of, see the attached data file for an example).
Regards,
Gerry
