Set to 50% with Comm Triggers
Overview
The Set to 50% control sets the trigger threshold to 50% for some Comm triggers and to a high of
75% with a low of 25% for others.
Behavior
When either AMI or MLT-3 code is selected with Comm triggers the Set 50% control measures
peak-to-peak level and sets an upper threshold value at 75% and a lower threshold value at 25%.
Other codes work exactly the same as Edge, Width, Glitch, and Timeout triggers; the threshold is
set to 50%.
Trigger on A Only (Horizontal Delay Off)
To Use
Select the trigger event from the A Event tab and then set up trigger controls for the A Event.
Next, select the A-B Seq tab and click A Only. Use the Horiz Position control to define the
amount of pretrigger data.
Behavior
When you select A Only with Delay Mode off, the instrument looks for the trigger conditions
specified by the A event. When the instrument recognizes the A event, it acquires the posttrigger
data.
Use the front panel HORIZONTAL POSITION knob to set the amount of pretrigger data.
Trigger on A Only (Horizontal Delay On)
To Use
Select the trigger event from the A Event tab and then set up trigger controls for the A Event.
Next, select the A-B Seq tab and click A Only. Use the Horiz Delay control to delay the
acquisition relative to the A Event trigger.
