HI, I'm stuck with a problem in interfacing the Rhode & Schwarz FS300 spectrum analyser to Matlab through NI VISA 5.0.3. I'm using Matlab 2011a. Create new Interface option in tmtool doesn't shows my instrument connected to the USB drive. The NI VISA interactive control shows my USB device, but listed as USB RAW. I beleive I need to get this listed as INSTR?
Any help ?

If you plan to communicate with the instrument using low level SCPI commands, via VISA-USB object - it has to be of USBTMC (Test & Measurement) class i.e. the VISA Resource Address must end with ::INSTR.
However, if you plan to communicate with the instrument using the industry standards such as VXIPnP or IVI - you can use the USB-RAW VISA Resource Address. Here's more help on how to use these drivers in MATLAB.
Hope this helps,
