About
Usually the WR reference clock is the source of the WR timing signals (10MHz and PPS), however, for low phase noise it is profitable to use the output of the local oscillator. In many White Rabbit systems the local oscillator has a different frequency than the White Rabbit reference clock which leads to a fixed number of possible phase lock positions. Using the local oscillator directly means that it must be phase aligned with the PPS in the WR reference clock domain. The process of aligning the phase of the external oscillator in the proper phase position is called LockSweep. LockSweep is explained and progress is reported based on experience with BabyWR..
