HI AGC Hold interval
The Comb fi lter is by default enabled.
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 fi ne.
It is recommended to use the default values.
Advanced Data settings
The advanced button enables the advanced settings for a data source.

7.5.6 Save as (create a custom fi le)
Creating a custom fi le
When the loaded fi le is a standard fi le there is a possibility of saving it as a custom fi le (= creating a custom fi le) , this is done with
the save as function. The saved fi le will always be a custom fi le (saved in the custom directory)
For sources that are often used, a custom fi le should be created. This custom fi le will then be loaded auto-
matically and will prevent the AutoImage from being launched.
