Calibrating
Locking Calibration Settings
The generator uses an internal hardware jumper to enable and disable changes to calibration settings.
If the Options > Calibration option is available, the jumper is set to enable re-calibration.
To prevent users from changing calibration settings:
1. Turn the generator off, and remove the back cover.
2. Locate the J10 jumper, which is near the lower-right corner of the board.
3. Connect the jumper to only one pin to disable user calibration. Connect both bins to enable user
calibration.
4. Install the back cover.
Adjusting Horizontal Scanning Frequency
Select Test > Freq Shift, and then press the +/- buttons to increase or decrease the horizontal scan-
ning frequency of the current video format +/- 10% in 2% increments. The ^ character indicates the
percent deviation. The bottom number is the actual frequency.
