Holdoff Settings

To access the Trigger Holdoff dialog, choose Triggers > Trigger Setup from the menu bar or press the

Front Panel Trigger Setup button, then touch the Holdoff tab.

Holdoff by - type of holdoff to use with trigger: None, Time (clock), or Event.

Time - if using Holdoff by Time, the time in S to wait before triggering.

Events - if using Holdoff by Events, the number of events to count before triggering.

Starts Holdoff Counter On - whether to count holdoff time/events from Acquisition Start or Last Trigger

Time before triggering again.

Software Assisted Trigger

Software Assisted Trigger is used to find the trigger-level crossing point closest to the hardware trigger

point. It then adjusts the time offset of the waveform so that it is aligned with the specified trigger level

and slope. Software Assisted Trigger provides a quick way to create eye diagrams.

NOTE: This feature can only be used with an Edge trigger type in Normal trigger mode.

1. From the menu, choose Triggers > Trigger Setup, then touch the Software Assisted Trigger tab.

2. Touch Enable.

3. Create a trigger window by entering a Hysteresis value. This value sets a boundary above and below

the main trigger level to exclude noise.

4. Choose Auto orNormal; this determine the trigger behavior when trigger crossings are not found in the

trigger source waveform.

l Auto mode allows all waveforms through the channel.

l Normal mode allows waveforms only with a trigger crossing within the horizontal gate region

through the channel.

5. Set Start and Stop time values on the Horizontal Gate part of the Software Assisted Trigger tab. These

values control where in the waveform the software-assisted trigger processing searches for trigger

crossings.
