I am actually using Labview 7.1 to acquire the data from my Wavesurfer 454. I can do it for one trace. It look like this “armed” the scope then when it gets the trigger, Labview collects the data.
The problem is I would like to collect the 4 traces after only one trigger… is it possible? Could you please explain me how to do that?
Because if I use a loop and change each time the channel to acquire, I need 4 trigger... although I would like to acquire them from the same trigger...
Many many thanks!

I recommend using the "lcwave" driver that's on NI's Instrument driver network. It includes an example for reading out multiple waveforms (2 channels)that can easily be extended to readout all 4 channels. To find the driver quickly, go to http://www.lecroy.com/tm/Library/Software/LabView/LabViewDrivers.asp?menuid=8 where you will find a link to the driver on NI's website. Let me know if you have any problems using the example.
