master PTP signal for the selected domain. The following values may appear:
No master present: Indicates that the master PTP clock has not been
detected on the selected domain.
Locked: Indicates that the master PTP clock is detected and there is less
than 1000 ns of phase lag between the master clock and the instrument.
Unlocked: Indicates that the master PTP clock is detected and there
is greater than 1000 ns of phase lag between the master clock and the
instrument.
PTP time: Shows the time derived from the PTP Master as UTC (Coordinated
Universal Time).
Master/Slave Phase Lag: Shows the detected offset between the master
and slave clocks.
Master ID: Shows the MAC Address of PTP Master with the bytes "ff:fe"
