There should be an example for NI RFSA in the NI Example Finder. The VI is called "MT niRFSA Demodulate AM.vi" You will have to change the polymorphic instance of the AM demodulation VI to SSB and maybe pass some filter data into the VI to get the desired results.

There is another example you can use to characterize what you will need to get your AM SSB demod to work. From there you can copy that code into the previous example and use it there to demodulate your signal.
The example is called, " MT AM-SSB Mod-Demod.vi" It should be located somewhere in this directory: C:\Program Files\National Instruments\LabVIEW 20XX\examples\Modulation\simulation examples\Programming.

Is the data coming into the demodulation VI valid? Do you know what kinds of parameters you need to demodulate the signal?
I can't really help code as I do not know what the data coming in looks like or should be. If you have specific questions about the VI or what it does I can help you with that.
