Currently I am using 2 picoscopes model 4224 and 4424 that capturing electromagnetic radiation from lightning events. The total horizontal window size is 2 seconds and I am using block triggered mode to capture the event with pretrigger delay set at 15%. The problem is to get the capture time with resolution of milliseconds so that we can capture with such format HH:MM:SS.xxxx. I have a GPS (USB) receiver connected to the same PC as the picoscopes. The question is does it possible to program picoscope 6 software to get the GPS timestamp when the system is triggered?
