12. Appendix E - Dual Trigger Input
DT15 Dual Trigger Module
*Note: Dual Trigger Mode and Incrementing mode are mutually exclusive.
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”
functioning
as a trigger input are located under the “Gate” menu
structure. The voltage threshold level and trigger edge for the “Gate” input can be adjusted from 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 assigned to either of the
trigger inputs. The default trigger source for each channel is the “Trig” input. The trigger source
selection is accessed in the secondary channel menus. To access this menu, press the button for
the channel of interest twice. Continue to press then the Page
button until the menu page 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.

Notes:
*TTG
Trigger-Trigger Input
Generates a software trigger pulse for the TRIG input only. Operation is
the same a receiving an external trigger pulse.
*GTG
Trigger-Gate Input
Generates a software trigger pulse for the GATE input only. Operation is
the same a receiving an external trigger pulse.
