Hi, I saved the VI for LV version 2014, hope this helps. testscope4_LV2014.vi

Hi @attila, The problem is solved. Using the functions from dwf.dll I am able to mimic the behaviour of WaveForms "Auto sync" in Labview. Just in case someone runs into the same problem I post the working VI. Thank you very much for your help! testscope4.vi

Hi attila, Setting "fgen/start" for ConfigureDigitalEdgeTrigger makes the VI hang (waiting forever for trigger, I guess). Even the the stop button won't stop the VI, I have to kill LabVIEW from the process manager. I can avoid this by setting Auto Trigger to True for MSO Run.vi, but then it auto triggers without synchronization, as expected.

Hi all, I use Analog Discovery 2 to generate a ramp up waveform and observe synchronously the response in the scope. The wavegen output W1 is wired to the scope input Ch.1. I want the scope to be triggered by the generated waveform, so that subsequent acquisitions yield signal that starts exactly in the same moment. I attach the VI that I have made to achieve this (testscope3.vi). I use Configure Digital Edge Trigger.vi to set up triggering. What I expect is that on each loop repetition the acquired signal would start in the same moment, but this is not the case. Each acquisition starts at an arbitrary moment and the signal moves visibly along the time axis. I am perfectly able to achieve the above using the WaveForms 2015 application (I attach the corresponding WaveForms 2015 workspace file), so I know that the hardware is capable of doing this. However, the experiment I need this for is controlled from LabVIEW and I would like to get the same result using the LabVIEW Driver for Analog Discovery 2. Thank you for any suggestions on how to achieve this from LabVIEW. testscope3.vi sweep.dwf3work
