Metronome Time Synchronization
Metronome provides time synchronization of independent Keysight chassis and chassis chains located anywhere in the world from multiple external time delivery sources.
When chassis are linked together into a chassis chain by sync cables, the time source selected for the primary in the chain is the basis for the timing of ALL chassis in that chain. Any time source selected for an individual secondary chassis is overridden by the timing supplied from the primary chassis.
Metronome is used with the XGS2-SD, XGS2-HS, XGS12-SD and XGS12-HS chassis and the AresONE fixed form factor chassis. Every metronome in the system can provide timing and triggers to eight chassis.IxServer logs detects the Metronome timing source and contains the entries for the primary chassis as shown in the following figure:

If IxServer does not detect Metronome, the logs will not contain the entries for the primary chassis as shown in the previous image.
Instead, IxServer will show legacy chassis chain information.IxServer logs detects the Metronome timing source and contains the entries for the secondary chassis as shown in the following figure:
