The Measurement Hardware DDK provides all of the documentation and examples which we have for RLP. It contains no documentation on our Signal Sources, including the NI 5411, because they do not support RLP.
You mentioned using NI-DAQ to program your instrument to work with LabVIEW RT. This method is used to program our modular instruments which are supported with LabVIEW RT, since LabVIEW RT cannot support their specific IVI drivers which offer optimum functionality. However, as listed on the web page linked in my first response, the NI 5411 is not one of the modular instruments supported with LabVIEW RT. So this method will not work using the NI 5411.
Unfortunately, it seems that you will need to find an alternative way to set up
your system since none of our Signal Sources can be used with LabVIEW RT. Please let us know if we can assist you further as you consider how to set up your system. For specific questions on setting up your system, I would recommend contacting us for phone support via www.ni.com/support.
Best wishes on your system.
