After publishing two drafts for comments, we’re now happy to announce that v1.0 of the “White Rabbit calibration procedure” document is available on OHWR. You can download it from the Documents section of the main White Rabbit project page.

The document provides step-by-step instructions to be performed to ensure your WR network is properly calibrated and synchronized with sub-ns accuracy. It also contains additional hints on how to measure the fiber link which is already deployed and how to recover a WR Calibrator parameters if your primary device got broken. Two appendices provide the mathematical proofs for the calibration correctness and the estimation of measurement errors.
