Figure 3–55: Delayed Triggerable
The oscilloscope is always acquiring samples to fill the pretrigger part of the
waveform record. When and if delay criteria are met, it takes enough posttrigger
samples to complete the delayed waveform record and then displays it. Refer to
Figure 3–56 for a more detailed look at how delayed records are placed in time
relative to the main trigger.
NOTE. Due to hardware limitations, the delayed time base cannot be made
triggerable when the main trigger type is Logic, any class, or when the main
trigger type is Pulse with Runt or Slew Rate classes selected. For these settings,
the oscilloscope will force the delayed time base to be in Runs After mode.
You use the Horizontal menu to select and define either delayed runs after main
or delayed triggerable. Delayed triggerable, however, requires further selections
in the Delayed Trigger menu. Do the following steps to set the delayed time base
to run immediately after delay:
1. Press HORIZONTAL MENU ➞ Time Base (main) ➞ Delayed Only
(side) ➞ Delayed Runs After Main (side).
