Eclipse Additional Information

3.7.2 General Setup

From the General Setup the user can setup and change basic test parameters. The functions not included by
your license will not be visible when connected to Eclipse hardware.

3.7.2.1 External Trigger Output

The unit has an electrical output socket carrying a synchronization signal, by which external stimulation de-
vices may be synchronized to enable ABR recordings.
The trigger pulse can here be set to match the individual requirements of such external stimulator devices.
The scrollbar controls the duration of this brief triggering electrical pulse 5 Volt TTL. Source selects a posi-
tive trigger signal and Sink selects a negative trigger signal.
Note Some external stimulation devices do not rely on a synchronization pulse from the ABR unit, but do
themselves send out a synchronization signal. In this case, use the same socket, but disregard this setting,
and set instead the Stimuli per sec. in the Auto Protocol setup to Ext. Trigger. Please refer to the section
eABR for a detailed description of the Trigger.

3.7.2.2 Auto Protocol Options (Separating ears)

Having the Separating ears ticked off will cause all selected intensities to be tested at one ear before start-
ing to test the other ear. If not selected, the test will follow the selected range intensities in order, testing one
ear at a time before descending or ascending to the next intensity.
The way in which Left and Right recordings are displayed if split screen is not used, is also determined by
this setting.
