  1. Hi @attila thank you very much! I appreciate your help. Now it is working like desired. Steven
  2. Hi @attila, thank you for the really fast answer. I tried as you wrote. I added the following line, to Trigger a positive pulse: dwf.FDwfDigitalInTriggerResetSet(_hdwf, 0, 0, Trigger_PIN, 0); dwf.FDwfDigitalInTriggerSet(_hdwf, 0, Trigger_PIN,0 , 0); Still it doesn´t matter what time i use in "TriggerLengthSet": dwf.FDwfDigitalInTriggerLengthSet(_hdwf, 0.5, -1, 0); If there is a signal on the Trigger Pin the samples are recorded and the recording goes to state "Done". How can i just Trigger when a pulse has a certain length? Steven
  3. Hello, i am trying to trigger an High Speed Pin after a certain length of a pulse. With the waveform software this works perfectly. Inside my c# code the "dwf.FDwfDigitalInTriggerLengthSet" has no effect. It doesn´t matter if i use 30ns or 10s for the minimum length. -> It triggers always directly after the first glitch of about 10ns. Thank you for your help in advance. Steven What am i doing wrong? Here the code: //Number of samples to acquire after the trigger (10 bit with 10Mhz) int number_of_samples = Convert.ToInt32(_frequency/(1e
