Hi,
I am attempting to create arbitrary waveforms using MATLAB, then sending it to my 6221 to generate the current. I am using a KUSB-488B card to connect my laptop to the 6221. I have installed the associated driver (version 3.12), and my laptop seems to be detecting the 6221, as shown in the image below.
I tried the following commands to try and create an instrument object.
obj = gpib('keithley',21,11)
and
obj = gpib('keithley',0,11)
While trying to create an instrument object, I keep getting this error "The specified VENDOR adaptor could not be found"
In the instrument control toolbox, MATLAB does not detect the 6221, as seen here.
Can someone please advise me on what I should do?
Thank you very much! :)

Hi
You might need to install 32-bit MATLAB instead of 64-bit MATLAB for this to work - this solved it for me.
