Setting sensitivity of knobs

You can control the amount of distance traveled with each click of the Format and Image
knobs by using the ACS, DCS, and DSS keys. If neither ACS, DCS, nor DSS is selected,
then the amount of movement is increased exponentially as you move farther in a particular
direction and is reset when you change direction.
To set the sensitivity of the Format and Image knobs:
1. Press the appropriate key:
Sensitivity
100 pixels/lines per knob click
10 pixels/lines per knob click
1 pixel/line per knob click
This section procedures for controlling the special sync probe through the front panel keys
and knobs.
To position the probe pulse in a specific location in the video signal:
1. Turn the Format knob to set the horizontal position of the probe pulse to the desired
pixel relative to the leading edge of the horizontal sync.
The horizontal position of the probe is simultaneously displayed in two different ways:
• The horizontal position P:nnnn is given in pixels relative to the leading edge of the
horizontal sync.
• If the leading edge of the probe is within the active portion of a line, an alternate
horizontal position X:nnnn is also displayed, indicating the number of pixels
Procedure
