I want to interact with Rohde and Schwarz Spectrum analyzer FSE-K30 using GPIB interface. Can anyone provide me the programming manual for the above mentioned spectrum analyzer and any details (VIs) regarding this spectrum analyzer to be used in LV. e.g. how to setup the analyzer.
The instrument you are using seems to be discontinued and you can find the manuals relating to that model here
As for VI's you can try the driver which seems to support the FSEK (not sure about the specific model) series here.
It should at least be a good starting point.
Let us know how it goes.
