        Note that we can't use RTTI for this because of software options that may or may not be present,
        and we don't know at object instantiation time.
 
        For example, some WaveSurfer 3000 devices have the function generator option and others don't.
        While the WaveSurfer 3000 DMM option is now no-cost, there's no guarantee any given instrument's
        owner has installed it!
