The AGC hold interval is the time interval in which the AGC is inhibited (AGC hold = no update in video amplitude measurement),
the advanced parameter allows to choose a short or long hold interval.
A long AGC hold interval eliminates Macrovision ® disturbances since the AGC is hold during a long interval, thus reducing the
probability to encounter a Macrovision ® pulse.
The sync locking setting is recommended for poor video signals (ex: poor TV signals).
Sharpness adjustment can be chosen to be coarse or fine.
It is recommended to use the default values.

The VCO range setting determines the frequency range of the VCO (Voltage Controlled Oscillator).
The Cpmp (Charge pump current) sets the low pass filter current.
Both VCO range & Cpmp are set by the image file, changing these settings is only indicated for special purposes.
The horizontal sync polarity setting can be useful in case of a bad shaped edge, one can choose between the leading (active low)
or trailing (active high) edge.
The input format settings are used to "tell more" about the signals connected on the BNC’s, it completes the information in the source
selection menu.
- RGB is selected by default and means that an RGB signal is connected to the BNC’s
- PR/Y/PB must be selected whenever:
• a progressive signal (32 kHz frequency video signal ) is connected to the BNC’s (select the source with Data on BNC’s in the
Source selection menu).
• one wants (in PiP mode) to visualize the component video signal in a Data window hereby adding a video image in the PiP
layout.
-HDTV-PR/Y/PB for high definition component video signals.
