33..1010..11 G0325A GPS ReceiverG0325A GPS Receiver
G0325A GPS Receiver contains GPS antenna and GPS receiver and is used by
connecting to AUX connector of Network Master. The synchronization
accuracy against UTC is ±1 μs or less.
The GPS receiver is used for:
Precise time synchronization, when making one way Frame Transfer Delay
measurements as part of the Ethernet Service Activation Test.
Clock source in an IEEE 1588v2 system
Timing source for synchronizing Ethernet transmitters
To perform Sync Test of Ethernet application, use the MU100090A. Installing the
MT1000A-005 AUX I/O is also necessary.
Activating the GPS receiverActivating the GPS receiver
The GPS receiver is activated automatically if it has connected to Network
Master.
Using the GPS serviceUsing the GPS service
One purpose of the external GPS receiver is to provide for precise one way
Frame Transfer Delay measurements as part of the Ethernet Service Activation
Test.
When the GPS receiver is activated and the active interface is Ethernet, the
Network Master will calibrate its internal time base to the ultra precise time
signal from the GPS receiver. The calibration process takes approximately 1
minute.

The MU100090A needs to connect GPS antenna and and to be connected to
the MT1000A using J1705A AUX conversion Adaptor.
Activating the GPS receiverActivating the GPS receiver
Touch the GPS icon, and setting MU100090A Power to OnOn will activate the
GPS receiver.
To realize ±45 ns rms accuracy against UTC, all the following conditions
should be met.
