MATLAB interface instrument driver

hey,

i am now try to connect the r&s zvb, a vector network analyzer to the matlab via gpib, I could succesfully create an interafce object and communicate through the interface. But I receive a error message, when I want to use the Matlab interface driver (.mdd file generated from Vxi Plug& paly driver i download from the r&s offical website). see code below for the error message.

d=icdevice('custom_matlab_rszvb_driver_3.12.0.mdd','GPIB::0::20::0::INSTR') Error using icdevice (line 233) The VXIplug&play driver referenced in C:\Program Files\MATLAB\R2014a\toolbox\instrument\instrument\drivers\custom_matlab_rszvb_driver_3.12.0.mdd cannot be found.

i have add the 'custom_matlab_rszvb_driver_3.12.0.mdd' into the C:\Program Files\MATLAB\R2014a\toolbox\instrument\instrument\drivers' and i am sure the the VISA Resource Address 'GPIB::0::20::0::INSTR' is correct.

any help? thanks.

I had the same problem. Matlab referred to the 32-bit driver, when I had the 64-bit driver. I just changed the filename of the driver.

Thank you very much and does it work after you chang the filename of the driver?

In C:\Program Files\IVI Foundation\VISA\Win64\Bin rename example_64.dll to example_32.dll.
