Warning: The noise parameters for each clock type are set up at the factory for best
performance. Any adjustments to these values must be performed by knowledgeable users as
changes can cause serious performance degradation.
Operators can check the status of the time scale using the settings reference:source and status
reference:frequency:timescale command.
