I try to control a Keithley 2306 by using VISA (the goal is using it
from python).
After installing NIVISA541full.exe, syscfg1601full.exe and
NI4882_1500f0.exe I started NI MAX but I get following error:
Error opening resource:
USB0::0x3923::0x702A::010A65AB::RAW
VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot
currently access it.
Sending IDN? from VISA Test Panel gives only:
Write Operation (*IDN?\n)
No Error
The Windows device manager shows an NI-VISA USB Device: "Device Model
Name", status: working correctly.
Maybe interesting also:
