jitter.

Notice

This setting only needs to be changed if a network switch without PTP support is being

used and more jitter is acceptable.

Notice

Interaction between different time synchronization types in complex set-ups may induce a

xed accuracy.

Use Accurate Master

Ensure that “accurate master”’ setting is disabled.

PTP Role (read-only)

Verify that the PTP Role is slave. If Master is listed in this column, the GEN series

mainframe itself is the master rather than the GMR1000.

Clock Class

The clock class should be 13 (GPS clock class if the GPS antenna is synchronized).

Notice

If the clock class is 14, IRIG is not locked and the GMR1000 runs on its internal clock.

If the clock class is 52, the GMR1000 was never synchronized.

PTP Master MAC-address

This is the GMR1000 MAC-address, or the boundary clock MAC-address when bound-

ary clocks are used.
