MAKEMID unable to interpret encoded .SUB files which is different from the default encoding scheme of the machine

I downloaded the Tektronix oscilloscope instrument driver from following page:

<http://www.mathworks.com/matlabcentral/linkexchange/links/3053-using-tektronix-msodpomdo-3000-and-4000-oscilloscopes-from-matlab >

I tried converting the driver to MATLAB instrument driver format using the following command:

>> makemid('Tkdpo2k3k4k')

This resulted in the following error:

Error using makemid (line 139)

File does not comply with the VXIplug&play sub file format.

MAKEMID can sometimes throw an error as shown below, when trying to create an MDD from an IVI-C or VXIPnP driver, such as the TEKTRONIX IVI-C Scope driver:

Error using makemid (line 139)

File does not comply with the VXIplug&play sub file format.

As the error suggests, the .SUB file is not formatted correctly. In this case, the .SUB file is encoded in UTF-16, but the default encoding scheme of the machine is different.

To work around this issue, do the following steps:

1. Navigate to the directory containing the .SUB file. Commonly, it is found under the directory:

C:\Program Files\IVI Foundation\IVI\Drivers\Tkdpo2k3k4k

You can also refer to the installation instructions on the vendor's site to find the installation files and locations.

2. Open the .SUB file in a text editor such as Notepad++.

3. Save the .SUB file with the same name but with ANSI(ASCII) encoding.

4. Rerun the command

>> makemid('Tkdpo2k3k4k')
