发明名称 Method and apparatus for tuning oscillator to a selected frequency
摘要 The present invention discloses an apparatus and method for tuning an oscillator to a selected frequency during power measurements of a neighbor list. In response to a received request for the oscillator to tune to a selected frequency, a controller associated with a switch determines whether the request comprises a first request for the oscillator to tune to the selected frequency. If so, the switch is placed in a first position, and the oscillator is provided a voltage control signal from a phase locked loop. The voltage control signal applied to the input of the oscillator is also saved at a location associated with the selected frequency. If the controller determines that the request does not comprise a first request for the selected frequency, a previously saved voltage control signal associated with the selected frequency is applied to the input of the oscillator by placing the switch in a second position. In either case, the oscillator is tuned to the selected frequency responsive to the applied voltage control signal.
