Hello,
I am working with a triggered signal input, where I receive a frame from the cscope driver. Additionally, Lets say I read another frame using replay. Is there a way to determine whether these two frames are same or different? For example, is there any ID associated with the frames or a specific timestamp indicating when they were recorded? The frame number keeps changing as new frames arrive, so it is not reliable for this purpose.

Hi, the Trigger time is an absolute time given in seconds since 1st January 1904 UTC. This provides a unique identifier for each frame. For example, running a python script I get -
Unit A:
T0dt.dt: 1e-06
T0dt.n: 10000
T0dt.T0: -0.005
T0dt.TTrig: 3815353823.5461407
T0dt.Frame: 0

Entering Ttring into https://www.doubleblak.com/blogPost.php?k=timestamps as a Apple MAC HFS+ (actually in our application it is as defined by Labview) if gives the date/time of 25 NOV 2024 04:30:23 UTC

So every frame/capture can be uniquely identified by that parameter.

Regards,
Roger
