Pulse out 2 interface
The synchronization pulse is only put out if the CMGPS is able to meet the
accuracy configured by the software.
At this interface the synchronization pulse of the
CMGPS can be picked up potential free via an
internal opto-electronic coupler (open collector). At
present, the
Test Universe software supports the
configuration of a pulse output only. Therefore,
Pulse out 2 is synchronous to Pulse out 1 .
