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
or
Normal
; 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.
