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 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 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
Chapter 5 , “Making Measurements,” starting on page
199.
Roll mode
• Press the Main/Delayed key, then press the Roll softkey.
• Roll mode causes the waveform to move slowly across the
screen from right to left. It only operates on time base
settings of 500 ms/div and slower. If the current time base
setting is faster than the 500 ms/div limit, it will be set to
500 ms/div when Roll mode is entered.
• In Normal horizontal mode, signal events occurring before
the trigger are plotted to the left of the trigger point (
t ) and
signal events after the trigger plotted to the right of the
trigger point.
