Hello
I fixed that problem now I can save the data for one chanel but now I faced
another problem: I can not save data for 8 chanel at the same time, I have
the higher andl lower chanel in the code but when I define them from 0 to 7
(8 chanle) I will get only one chanel

I also tried to copy and past the case and in the copy version I set the other chanel
but it does not work becuse each each run should be finnished and then the other one
should be started.
thank you very much for your time
