I've been trying to connect a Keithley 2400 Sourcemeter to a computer using a GPIB USB HS device,
I'm certain that the device drivers have been installed correctly as the device shows up on the VISA interactive control window.
However, whenever I try to send a command I get an error message saying that the interface is non-genuine and that I should contact National Instruments for support.
I wasn't entirely sure where exactly to ask so I decided to ask here, if this is the wrong place, would you kindly direct me to the correct place?
I have attached the error and an image of the GPIB device
Any help would be appreciated
