4 Operating the STG
4.1 Operation Overview
Warning: Make sure that you do not come in contact with the cables or the connectors of
the STG after you have started the STG. The high voltage and power can lead to
injuries .
Warning: Do not start the STG if you are unsure about the channel configuration or the nature
of the downloaded file.
1. Set up your experiment.
2. Switch the STG3008-FA on.
3. Set up your stimuli with the MC_Stimulus II program.
4. Send the stimulus sequence from a MC_Stimulus II file to the STG.
5. Start the STG either manually by pressing the Start / Stop button on the front panel,
with the software controls, or with an external trigger.
Creating stimuli
Stimuli are created user-friendly by entering the desired pulses (rectangular, ramp, or sine
waveforms) into a MC_Stimulus worksheet. Waveforms can be combined freely to create virtually
any stimulus pattern. Created stimuli are displayed in a WYSIWYG window.
Starting stimulation
Note: You need a computer connection only when you are using the software controls for starting
and stopping the stimulus generator. When you are using the STG interface or an external control
(trigger, you can disconnect the stimulus generator from the computer and operate it
independently. But you cannot remove the STG from the power connection. The memory
is cleared when the STG has lost power.
After the download of the stimulus file on the STG, you can start the stimulation. There are
several ways to start the STG.
MC_Stimulus
II interface: You can start the stimulation directly after the download (with the command
Download and Start or also later with the command Start . You can
stop stimulation with the command Stop . Starting the STG by using the
Start command is considered as activating the trigger input and the Sync Out
output. Likewise, all channels are stopped when you click Stop.
You can start the stimulation after download on the trigger. Please use
the combined LED / Start / Stop buttons . You can start and stop the
stimulation manual whenever you want by clicking the corresponding LED /
Start / Stop button. The LED indicates the status: Grey means trigger off, red
means trigger on. In STG3008-FA only trigger 1 is available.
STG
interface: You can start the stimulation by pressing the Start / Stop button on the front
panel of the STG. Press the button again to stop the stimulation. Starting the
STG by pressing the Start / Stop button is considered as activating the trigger
input, that is, all channels are started and stopped, and the Sync Out output is
active when the STG is started. Pressing the Start / Stop button stops the
stimulation if at least one channel is still active in the moment of the trigger
