Select the “Event Duration” in milliseconds from the numeric updown box. The event duration
is the time after a crossing of the detection threshold that the detection condition is considered
as fulfilled. This duration influences the length of the resulting feedback TTL, and is especially
important when the input from several electrodes is combined with the “AND” and “OR” function
(see below). That means, for the Feedback Logic, the logical state of a channel becomes TRUE
from the detection point of an event till the end of the event duration.
Please see image below:
If only one channel is used as input, the duration of the resulting digital TTL pulse is as long as the
logical state is TRUE. As usual you have to download all settings to the DSP with the “Download”
command.
Individual settings: The following control functions are available for each output bit of the
digital channel:
Select the channels you want to detect signals from by clicking onto the channel block.
The layout on the channel block depends on the settings in the Data Source Setup.
Selected channels will be highlighted in grey. Deselect a channel by clicking it again.
Events from the same electrode can be used in more than one logical block.
Select the bit of the Digital OUT you want the condition to be assigned to. The Digital OUT
has 16 bits, D0 to D15.
