Hi Nonox,

That error means:

Possible reason(s):

VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed.

There can be many reasons for this and two most common problems that I see or hear about are:

1) Not having the proper serial settings.  The serial settings of the scope (baud rate, parity, data bits, handshaking, etc.) has to match the settings that you are configuring on the computer.  In the case of the driver, they need to match the settings that can be configured by the "Initialize" VI.

2) Not having a long enough VISA Timeout.  If you have a dense waveform (5M+ data points), you might want to increase the VISA timeout on the block diagram of the "Initialize" VI so that it will allow the read VIs to have more time to get the entire waveform.  However considering the scope that you are using this is unlikely.

I hope it helps.
Good luck!
