Reference Monitoring

Reference monitoring enables you to assess the quality of your references by comparing them
against the current system reference, and against each other. This allows you to predict or
understand system behavior in the event that the current system reference will be lost, or was
lost, respectively. You may also decide to alter reference priorities as a result of monitoring
their quality e.g., assigning a lower reference priority to a noisy reference, or a reference with
a significant offset.
SecureSync allows Reference Monitoring by comparing the phase data of references against
the System Ontime Point. The phase values shown are the filtered phase differences between
each input reference 1PPS and the internal disciplined 1PPS.
The data is plotted in a graph in real-time. The plot also allows you to display historic data,
