Single Trigger
Important: This feature is available only with STG 4000 series. The MC_Stimulus II version 3.2.3
(or later) with firmware update must be installed.
Additional to the general trigger states “running” and “stopped” each trigger can now be set up
in a new state, called “armed”. That means, the trigger is ready to start the stimulus protocol, but
waiting for an external signal from the rear panel trigger inputs to execute the stimulus protocol
one time only. In “armed” state, the “Sweep” LED on the front panel of the STG will light up in
blue, but the brightness of the LED is not as brilliant as in “running” state.
Select “Single Trigger” if you want to start the stimulus protocol once via external trigger.
Set up your stimuli with the MC_Stimulus II program. Download the stimulus protocol from
a MC_Stimulus II file to the STG. Arm the STG either manually by pressing the Start / Stop button
on the front panel, or with software controls. To arm the STG via software, use the start icon in
MC_Stimulus II main menu, or click the combined LED / Start / Stop button for the
“Sweeps”. When armed, the STG accepts one single trigger on its trigger input The trigger input
must be connected to the device which generates the trigger. To start the stimulus protocol
a second time, the STG needs to be armed again manually. As long as the STG is armed, the LED
in MC_Stimulus II appears blue to indicate the armed state.
The stimulation will automatically be started after applying the single trigger from the external
device. The LED in will turn to red while the trigger is running and return to grey after the trigger
has finished the stimulus protocol The STG needs to be armed again to accept the next trigger.
It is possible to stop the stimulation at any time while the STG is armed or is running via Start /
Stop button on the front panel of the STG or via software.
