[happybird]

Hellow!
Is it possible to control two or more TDS 420A Osilloscope at the same time? i have tried the"TKTDS read waveform.VI" ,it is OK for one osilloscope,but when i connect two Osilloscope,it will not work,so are there any way to do it? thanks!

I assume that you are communicating with them through a GPIB bus using VISA. If so, make sure that they have different addresses. You cannot have two scopes on the same bus with the same address. I've tried :).

Let us know if any of my assumptions is incorrect as well.

Hope that this helps,
