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 STG on.
Note: It is recommended to start the STG ten minutes before use to allow warming up!
1. Set up your stimuli with the MC_Stimulus II program.
2. Send the stimulus sequence from a MC_Stimulus II file to the STG.
3. 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,
a trigger for example, 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 all trigger inputs, that is, all channels
are started, and all Sync Out outputs are active. Likewise, all channels are
stopped when you click Stop.
You can start the stimulation after download on both trigger separately.
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. The first button on the left side belongs to trigger 1,
the second button to trigger 2.
