The present invention discloses an apparatus an a 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 (90) associated with a switch (70) determines whether the request comprises a first request for the oscillator to tune to the selected frequency. If so, the switch (70) is placed in a first position, and the oscillator is provided a voltage control signal from a phase locked loop (60). 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 (90) 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 (70) in a second position. In either case, the oscillator is tuned to the selected frequency responsive to the applied voltage control signal.
