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.
