3.3.4 Pulse out 2 Interface
The Pulse out 2 interface is represented by two safety banana sockets.

The Pulse out 2
interface
Via these banana sockets, the synchronization pulse of the CMGPS can be
picked up potential-free by means of an internal opto-electronic coupler (see
also section 6.6 ”Pulse Out 2 Interface” on page 38).
It is put out following the standardized factory setting simultaneously to the
synchronization pulse at the ext. Interf. connector.
Standardized factory setting of the synchronization pulse is 200 ms output once
per minute.
This interface has been especially designed for the synchronization of a CMC
test set without an integrated ext. Interf. connector.
In order to be able to trigger these CMC test sets by means of the GPS signal,
the CMGPS synchronization signal from the Pulse out 2 interface may be
connected to one of the CMC's binary inputs (see also documentation of the test
set and/or software).
By means of the Pulse out 2 interface, the CMGPS can also be utilized as
"standalone" synchronization unit without being connected to a CMC test set.
At present, the Test Universe software supports the configuration of a pulse
output only. Therefore, the Pulse out 2 is synchronous to Pulse out 1.
