5. Video Reference


To navigate through the settings you must enter the setup mode by
pressing one of the MENU keys [

] or [

].

The currently selected parameter section starts flashing to indicate
you are in the setup mode.

With the MENU buttons [

] and [

] you can move form one section

to the next. When saving the settings, the menu position will also be
stored and reappears at the same position when the setup mode is
called up again.

Press both menu keys (S3) (S4) to exit the setup mode and store all
settings to non volatile flash memory.


Enter the setup mode and select the video reference section with
the SELECT key.


INTERNAL:

The internal 0.5 ppm accurate crystal oscillator is the
master for both video generators.

Blue LOCKED LED in the video section will be on.
An applied reference signal at the video sync input
connector will be ignored.

EXT. PAL:

The unit locks to an external PAL video reference
signal applied on the video sync input connector
(C7). The 25/50 LED in the video reference section
indicates that there is a video input signal present at
25 fps. When the internal SD generator is set to
PAL 25 the outputs will be 8 field and subcarrier
genlocked to the PAL video input signal.

LEDs 24 or 24 and -0.1% indicate the detection of a
slow PAL reference at 24 or 23.98 fps.

The blue LOCKED LED in the video section indicates
locked operation to external PAL references.

EXT. NTSC:

The unit locks to an external NTSC video reference
signal applied on the video sync input connector
(C7). The 30/60 and -0.1% LEDs in the video
reference section indicate that there is a video input
signal present at 29.97 fps. When the internal SD
generator is set to NTSC, the outputs will be 4 field
and subcarrier genlocked to the NTSC video input
signal.

The blue LOCKED LED in the video section indicates
genlocked operation to an external NTSC reference.


A 30 fps "black & white" input signal is indicated by
the 30 fps LED without -0.1% LED.

The nanosyncs HD will also lock to 30 fps signals.



EXT.TRI LEVEL:

The unit locks to an external Tri Level Sync signal
applied on the video sync input connector (C7).

The four LEDs 24, 25/50, 30/60, -0.1% in the video
reference section indicate the automatically detected
input frame rate.

When the input frame rate matches the SD or HD
generator frame rate a phase lock will be performed
(phase locked means that the according v-sync
patterns are reset exactly to the same position as
where the video input signal v-sync is located).

The blue LOCKED LED in the video section indicates
genlocked operation to an external Tri Level
reference.
