4. Input/output signal settings
4-6. Setting the sync signals
The sync signals to be used by the system can be selected.
External sync: For synchronization with an external sync signal (gen-lock).
The reference input signal is looped through and output.
BBST: Black burst signal (vertical phase of 0H)
BBAD: Black burst signal
Vertical phase of 90H when the 59.94i or 59.94p format is selected;
vertical phase of 75H when the 50i or 50p format is selected
TRI: Tri-level sync signal (vertical phase of 0H)
This can be selected when HD format signals are supplied.
Internal sync: For synchronization with an internal reference signal (INT).
The REFOUT signal (black burst signal) is output from the two reference connectors.
Press the [SYSTEM] button to light its indicator and display the SYSTEM menu.

Turn [F2], select the sync signal using the Sync item, and press the [F2] switch to enter the selection.
An asterisk () appears at the left of the reference signal currently selected.
Turn [F3] to select the setup level of the black burst signal in the internal synchronization mode using the
BBSetup item.
This setting takes effect when the video system is 59.94i or 59.94p.
The setup level is fixed at 0 IRE when the system is 50i or 50p.
The genlock status is displayed in the GenLock item.
Locked: Synchronized with the external sync signal or internal reference signal.
UnLock: Not synchronized with the external sync signal or internal reference signal.
 When 1080/23.98PsF or 24PsF is selected as the format, INT (internal synchronization) cannot be selected in
the SYNC item of the REF sub menu.
 This unit supports synchronization signals for field frequencies that are same as those of the system format.
When the unit is set to the 1080/23.98PsF format, however, the unit also supports black burst signals with
10F-1D (compliant with the SMPTE318M standard).
