Knobs Explanation
The horizontal controls change the horizontal scale and position of waveforms. The
horizontal center of the screen is the time reference for waveforms. Changing the
horizontal scale causes the waveform to be expanded or compressed with respect to
the screen center. Horizontal position changes the displayed waveform position,
relative to the trigger point.
1. The horizontal knob adjusts the horizontal position of all
channels (including Math) waveforms. The resolution of this control varies with
the time base. Pressing this button clears the trigger offset and moves the
trigger point to the horizontal center of the screen.
2. Use to select the horizontal time/div (scale factor) for the main or
the Delayed scan time base. When Delayed Scan is enabled, it changes the
width of the window zone by changing the Delayed Scan time base.
