I'm having trouble relating my captured data to the system time. I have a PicoScope 5204 available, which I'm using to measure a pulse using a trigger. I use an alarm to save the captured data. So far so good.
The device that produces the pulse is time synchronized with the laptop that is connected to the PicoScope. What I want to accomplish is to compare the production time of the pulse (produced by the device, measured with the scope, so time stamped with the laptop) with the event (logged within the device, so time stamped by the device) that triggered the pulse. I hope I'm making sense here
When I open the datafile, a capture time stamp is shown. I'm a little confused about relating the timestamps of the captured samples to the capture time stamp. The trigger time seems to be at t=0, but how is the trigger time related to the capture time stamp?
I have looked at the manual, but could not find the details I'm looking for. It seems to be the same as the timestamp of the file itself, so a property of the file system. Could that be the case?
Also, when I export the data to Matlab, the capture time stamp does not seem to be part of the exported data. How do I obtain the capture time stamp in that case?
Your help in enlightening me is much appreciated.
