MegaZoom Concepts and Oscilloscope Operation
To setup the Horizontal time base
To change the sweep speed for the delayed sweep window, turn the sweep speed
knob. As you turn the knob, the sweep speed is highlighted in the status line
above the waveform display area.
The time reference position sets the initial position of the trigger event within
acquisition memory and on the display, with delay set to 0. The delay setting
sets the specific location of the trigger event with respect to the time reference
position. The time reference setting affects the delayed sweep as described in
the following ways.
When the horizontal mode is set to Main, the delay positions the main sweep
relative to the trigger. This delay is a fixed number. Changing this delay value
does not affect the sweep speed. When the horizontal mode is set to Delayed,
the delay controls the position of the delayed sweep window inside the main
sweep display. This delayed delay value is independent of sampling interval and
sweep speed.
To change the sweep speed for the main sweep window, press the Main softkey,
then turn the sweep speed knob.
For information about using delayed mode for measurements, refer to the
“Making Measurements” chapter.
