ABSTRACT:
A Method and Apparatus for Enhancing the Speed of Wideband Signal Search Systems provides a system that can perform hyper fast scanning for signals while at the same time provide very good phase noise performance. The method and apparatus provide a way to reduce costs by avoiding the expensive solutions employed by the unmodified prior systems. The method and apparatus have all of the abilities of standard wideband signal collection systems. Secondly the method and apparatus are able to automatically, and extremely quickly, control multiple VCO's in a finely coordinated tuning process. Thirdly, the method and apparatus still have very good phase noise performance, even though it has hyper fast tuning speeds. Fourthly, the preferred method and apparatus pipeline the digitization and tuning phases of the collection process. Finally, the method and apparatus provide real-time control logic to accurately synchronize all events and make them work in the specific procedure at their respective specific microseconds in time.
