Chapter V Trigger System
41
The 4456 series is adopted with the brand-new visible trigger technology, so that the oscilloscope can scan all
waveform acquisitions, compare them with the waveform area on the screen, and quickly and easily identify target
trigger events by simply observing interested signals on the screen and drawing a zone around it.
Click [Zone&Qualified] menu key during the edge or pulse width trigger, and open the Zone setup menu.
Fig. 5.41 Zone Menu
Source: Select the waveform of the corresponding channel as the Zone source.
Zone: The In and Out can be selected for judgment.
On/Off: When the ZoneQualified is on, it can be drawn by touching and dragging in the waveform area and made
as the trigger judgment zone.

Trigger holdoff
The trigger holdoff is used to stably trigger the complex waveforms, such as pulse burst signals. The holdoff time
refers to the time that the oscilloscope waits to restart the trigger circuit. During holdoff, the oscilloscope will not
be triggered until the end of the holdoff time.
