Trigger In Setting
Description
Source
Button:
The Trigger event is provided to the instrument by the Trigger
button on the keyboard or Trigger button on the menu bar or from a
Remote Command.
Timer:
The Trigger is internally generated by a Timer. The Timer count is
set by Interval [s] textbox.
External:
The Trigger event is generated by the signal applied externally
on the BNC connector (TRIGGER IN) when it crosses the selected
Threshold with the selected Slope. You can select Threshold value and
Slope using the relative textbox and slider.
Note:
The Trigger buttons and the Trigger from remote command are
always active, independently from the selecting Trigger Source.
Interval [s]
Set the timer count. It has effect only when the selecting Source is Timer.
The Interval range is from 13.4ns to over 100s.
Slope
The Slope can be positive, negative or both. When positive is selected the
trigger detected

BNC connector
crosses the threshold from low to high. The negative option is the
opposite, the both options detects the trigger on both edges. It has effect
only when the selecting Source is External.
