PBZ
Synchronization Feature
Clock Synchronization
Connect coaxial cables to the rear panel reference clock I/O terminals (10 MHz IN and 10
MHz OUT terminals). Regardless of whether the units are set to operate synchronously or
not, you can synchronize the clocks of all PBZ series units as well as synchronize the clocks
of PBZs with the clocks of external devices. When the internal clocks of all units are
synchronized:
• All units have the same frequency accuracy.
• The specified phase relationships of the AC signals of all units are maintained.
• All units have the same sequence execution time accuracy.
• If all units execute the same sequence, they all change steps at the same time.
If a signal that exceeds the frequency range that is listed in the specifications is applied to the
10 MHz IN terminal, the following screen (10 MHz UNLOCKED) may appear. If this happens,
the PBZ’s clock is out of sync with the external devices.
