You can either download a preconfigured MATLAB instrument driver from the MATLAB Central File Exchange at /matlabcentral or create it using the command-line function makemid. With many programming environments, you work directly with vendor-supplied IVI drivers, but to run them in MATLAB, you must first create a MATLAB IVI driver that acts as a wrapper for the IVI-COM or IVI-C driver which must remain installed on the system. In MATLAB, you can work with graphical tools, but most development is done from the command line. In fact, it’s possible to create hybrid systems that combine LXI instruments with those using other bus or backplane schemes. When working with familiar development environments, programming an LXI instrument isn’t considerably different than programming other classes of instruments. You aren’t limited to these tools if you, instead, program LXI instruments directly with SCPI commands. Well, today not every one supports all LXI instrument classes, not all accommodate both IVI-COM and IVI-C drivers, and some require that you purchase advanced versions or extra modules to gain LXI access. Several vendors-most notably Agilent Technologies, Data Translation, The MathWorks, and National Instruments-have adapted their application development environments to support LXI system development. With more LXI hardware coming to market and engineers taking a closer look at this technology, questions from developers and system integrators also involve software issues: What tools are available to help me program an LXI system, and how do they differ? For example, what debug facilities are at my disposal?
