Appendix D - DT15 (Dual Trigger Option)
DT15 Overview
This module option allows the “Gate” input to function as a second trigger input.
For consistency, the enabling menu for this option is located under the “Trig”
menu structure. Once the dual
trigger mode is enabled, both the “Gate” and
“Trig” inputs can act as trigger inputs.
Adjustments for the “Gate” trigger input are located under the “Gate” menu
structure. The voltage threshold level and trigger edge for the “Gate” input can be
adjusted f
rom this menu. The “Gate” trigger edge choice is only available when in
dual trigger mode.
Once dual trigger functionality is enabled on the unit, each channel can be
as-signed to either of the trigger inputs. The default trigger source for each
channel i
s the “Trig” input. The trigger source selection is accessed in the
secondary channel menus. To access this menu, first press the yellow “Func”
button followed by the channel of interest. Continue to press “Func” then the
channel button until the menu pag
e with “Ch Gate:” and “TrigSrc:” appears. Use
the “Next” button to place the cursor on the “TrigSrc” line and use the up/down
arrows to change to the desired trigger source.
