Sorry for my english, i'm french.
I want to transfer the four channels from oscilloscope to my graph on labview but sometimes the channels 2 and 4 aren't completed. I don't understand why?
thank you for your help.

Hi,

What behavior are you observing (errors, timeouts, etc)?.

I couldn't find anything specific to what you describe. Here are some generic knowledge base articles in found:

How Do I Use a Scope Specific Instrument Driver to Acquire Multiple Waveforms Simultaneously?

Hope this helps.

the curves are not transferred entirely. Normaly they have a length of 10000 points but sometimes I have only 3465 points.
