1. Select several cells by clicking and dragging cells in the Group Repeat column.
Selected cells are highlighted in black.
2. Point to the selected cells and right-click to open the context menu.
3. Click Group / Ungroup. The corresponding rows are grouped now. This is indicated
by a merging of the Group Repeat cells.
4. Type the number of repeats into the merged Group Repeat cell.
Repeating complete pulse protocols (autorepeat function), Continuous Mode
You can repeat the complete stimulus on all output channels that are triggered by the same
trigger. This means, each time when a trigger event occurs, the complete stimuli on all
corresponding output channels are repeated for the specified number of times. If the stimuli
have different lengths, the starting points are synchronized. For example, if channel 1
has a stimulus with a length of 500 ms, and channel 2 of 1000 ms, and both are triggered
by the same trigger event, channel 1 waits 500 ms for the repeat until the output stream
of channel 2 has been finished.
Note: The Sync Out signal for the corresponding trigger is repeated as well each time the stimulus
is repeated.
Hint: You can repeat the complete stimulus protocol that is assigned to a trigger continuously
by using the Continuous Mode setting. Continuous mode can be activated in the main window
or under Trigger Settings. The STG has then to be stopped manually by the user. You can use this
feature regardless whether you use an external trigger input or not. When you press the
Start
button, this is considered as if all trigger inputs were active. When you use Continuous Mode,
the repeats entered in the Trigger Settings dialog box are disabled.
1. On the STG menu, click Trigger Settings.
2. Enter the number of repeats for each trigger separately. 0 repeats the output signals
continuously.
