Hello,
I´ve been measuring the digital triggers from my scope, and it seems that they are in the range of 3.3V instead of the 5V used for TTL. Sometimes, my VI runs smoothly with a trigger, but other times it seems to only do half the run. I checked the code several times, and didn´t see any relevant issues that could force the data to be curtail to half. My reasoning is that since it has two QCLs, that the trigger that I use may produce another rising TTL signal when it changes QCLs, leading to the DAQ to run only for that amount of time before the process is ended with the laser emission being terminated. As such, I was wondering if there is a way to lower the threshold voltage to trigger the digital trigger in LabView.
Please find enclosed my VI. Thank you in advance for your assistance!
