<p>A device is provided having a local oscillator (LO) configured to generate a first signal comprising at least one of: timing information; frequency information; phase information; and combinations thereof. The device also has a LO error corrector comprising an input, the input configured to receive a second signal comprising at least one of: timing information; frequency information; phase information and combinations thereof, wherein the second signal is used for disciplining the LO. The LO error corrector is configured to: if the second signal is unavailable to discipline the LO, discipline the LO using a source that is less accurate than the second signal. Upon the second signal becoming at least temporarily available, the LO corrector determines an offset error of the LO relative to the second signal. If the second signal becomes unavailable before the device uses the second signal to discipline the LO on an ongoing basis, the LO corrector corrects the offset error of the LO relative to the second signal based information obtained during the second signal's temporary availability and disciplines the LO using a source that is less accurate than the second signal until the second signal becomes at least temporarily available at a subsequent time.</p> |
