can we talk over email because it is much more quickly than forum? here is my adress: kaiuwe.bentele@gruner.de

Sry but the psdata is also to big. What I want to measure is the time between the moment when the blue signal is going to high and the moment when the red signals amplitude is going to 0. And also i have to ensure that the red signal is 0 over the whole time to the next puls from the blue signal. Wh...

Sorry the psdata is to big to uploading it. But her you can see a picture.

Sample Interval: 1000
Pre-trigger Samples: 0
Post-trigger Sampls: 1000
Down-sample mode: none
Down-Sample Ration: 1

I had tryed tries sometimes left but something was wrong because the time between these two events is approximately 30ms mesured by PicoScope 6. When I measured the Time with LabView the way you describe it the results are around 200ms. Can you post me some examples or something els?

Yes, to see the Stream Data is no problem. At the moment I am displaying the wave with a diagram.

I will tell you now the whole problem about the measurement task, maybe you can give me better support. I have to control one contact of a relay, as starting point of the measure I have the digital relay control signal. When the control signal is going to high I should measure the time to the point ...
