Simultaneous sampling using Tektronix TDS 2014

[AndrewAlford]

The scope does not support what you are trying to do. If you want to collect two waveforms captured during the same acquisition you must use the "Single Sequence" acquisition feature of the scope.

Hi Matt G,

Can you put your VI on the forum to see what you did to solve your problem?

Thank you for your help.

Best,

Albert have the solution to Matt G's problem. Have you done this?

[Jibouille]

Hi Dennis,

I do not really get the advise given by Albert. Indeed, I triggerred only one acquisition and that didn't work. I use a loop to continously record simultaneous channels and the trigger is outside the loop. I put my programme in attachment as well as a screen shot of my problem.

Thank you for your help.

First of all, I think you should be setting up a Sample mode and trigger on DC.

Move the setting of the acquisition mode to outside of the loop.  The Get Waveforms actually starts the acquisition.

Hi Crossrulz,

Thank you for your advice. Nevertheless, that doesn't work because if i move the acquisition mode outside the loop. First, the lag is still present. Second, that doesn't record properly. Finally, there is no graphic visualization because the graph stays fixed on the first loop.

Best,

Jibouille
