MATLAB: MATLAB interface instrument driver

gpibInstrument Control Toolboxtmtoolvisavxiplug&playzvb

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.

MATLAB: Problem with vxipnp driver

After all, I discovered that I was working in a different drive (d:) than the one where the IVI, VISA, etc. were installed, and the problem disappears when I execute deviceObj = icdevice('zvb8driver.mdd', 'TCPIP::192.168.1.2::INSTR'); and connect(deviceObj); in c:

MATLAB: MATLAB interface instrument driver

MDD files can be of multiple types. For example:

1. MATLAB Interface Instrument Driver 2. MATLAB VXIPnP Instrument Driver 3. MATLAB IVI-C Instrument Driver 4. MATLAB IVI-COM Instrument Driver

Depending on the MDD file type the second argument to the icdevice function changes.

For MATLAB Interface Instrument Driver the second argument to the icdevice function should be an interface object (and hence MDD is called "Interface" Instrument Driver).

However, if the MDD is any of the other three types, the second argument to the icdevice function should be the VISA Resource Address (In your case: USB0::2391::65519::CN03225604::0::INSTR)

If you created agn9320ni.mdd from a VXIPnP driver, then you need to pass in the VISA Resource Address as the second argument:

 d = icdevice('agn9320ni.mdd','USB0::2391::65519::CN03225604::0::INSTR');

More information on the MDD types can be found at the online help. Here's more information on how to use industry standard drivers.
