The Spotlight Wideband Parameterizer differs from the Very Wideband
Parameterizer (VWBP) in that it analyzes up to twenty megaHertz of RF
bandwidth in real time, instead of several hundred. The Spotlight
system is hosted on an array of small form factor HP servers and uses
entirely digital processing techniques. The reduced bandwidth relative
to the VWBP allows for a simpler and less costly system, while
maintaining the same quality of parameterization.
