Labview PicoVNA error after installing picoVNA3

Post by Rednecknerd »

Was using the Pico VNA S-parameter Example just fine with PicoVNA2 installed.

After installing PicoVNA3 my code and the example code started giving errors.

Invoke Node: Invalid method
Invoke Node: Invalid refnum class

Windows 10
Labview 2014

Hi,
Are still having this issue?
Which model VNA do you have 106 or 108?
What version LabVIEW are you using? 32-bit or 64-bit?
Do you know which "Invoke Node" function is generating the error?

Hello, can I jump into the discussion?

I have a PicoVNA 108 which is correctly recognized and working with the PicoVNA3 software.
I need to use LabVIEW, but it's not able to communicate with it... please see the attached screenshots.

I see there is a "picocontrol2._PicoVNA_2" control. Maybe it was compatible only with the PicoVNA2 version? just guessing, I have never used the previous version.

Thank you very much!
