Hello all,
I´m trying to synchronize a digital output signal (in the end it should be a short TTL pulse) to an analog output (beam position change of an electron gun in a SEM). With this I want to tag the beam position change. I the already existing program there are the detector counters already synchronized (counter inputs) and this works properly.
My problem: the TTL pulse is only ocurring every 4th analog output change (see attached images) and not every time. Furthermore I want to determine the pulse length to 0.5 µs and this has not worked for me. What I am doing wrong or what is missing?
I use an PCIe 6343 device with a Windows 7 32-bit computer.
Thanks a lot for your help!
