Absolute trigger time

Post by JasonS » Thu Sep 20, 2018 3:15 pm

I'm using a PicoScope 6000 device. In my application, I would like to know the "absolute time" a trigger event occurred. Fortunately, for my purposes, I don't need accuracy much better than about 100 ms. Even with this relatively lax requirement, I'm unsure how to proceed. I can use my program to get the wall clock time just before I initiate the acquisition with ps6000RunBlock. But how long is it from when the scope is armed to when the trigger event occurs? If I knew this, I would simply add it to the wall clock time and that would be good enough.

I considered using one of the GetTriggerTimeOffset family of functions, but this doesn't seem to really do what is needed. GetTriggerInfoBulk looks promising, but it is undocumented.

How can I solve this problem?
