i have issue with connecting labview with Rigol DS1054 osciloscope.
I have already installed NI-VISA 18.5, NI-SERIAL 18.5. Labview version is 16. Also rigol DS1000 driver has been instaled.
I get error message: Error -1073807346, VISA: (Hex 0xBFFF000E) The given session or object reference is invalid. In att.
It seams that labview and VISA doesn't see COM port's.
Has someone idea, how can i solved this issue?
Thank you for your support.

Hi milan,
in visa resources i have only refresh, not a single COM.
Because there is no COM port visible in your MAX screenshot.
Are there any in your (Windows) device manager?
When there is a COM port, then MAX shows it like this:
connection is over USB.
Why do think you need to use COM ports, when the scope connects over USB?
What does the manual of your scope say about this topic?

Hi Gerd,
i find what was the problem.
Osciloscope was not set correctly, for sending data over USB PictBridge.
Now i get visa resource and picture on my screen! 🙂
You can check results in att.
Thank you on your help and time!
Best regards.
