Configuration
Format Setup
Table 4 lists the nominal output signal levels for each format selection with
a 100% saturated/100% luminance color bar signal.
Level Adjustments
The factory (default) settings for signal processing functions are set to pass
a calibrated broadcast quality signal at optimum levels. Signal video and
composite sync DC offset and output level adjustments are available to
correct deficiencies in the input signal.
Once any video or composite sync adjustments are made, it is recom-
mended to save these settings on the User Settings web page (
User Settings
Web Page on page 31 ). If the format is reselected from the pulldown, the
Level values will return to the factory defaults for that format.
Timing/Blanking Adjustments
The following adjustments can be made to the signal that affect timing and
blanking:
• Horizontal delay – adjust the amount of horizontal delay in ns,
• Sync On G – sync may be turned on or off on the Y/G channel output
in GBR, and
• Vertical blanking – set vertical blanking to Pass or Blank all vertical
data.
