33..44..33 GPS Disciplined Oscillator InterfacesGPS Disciplined Oscillator Interfaces
All connections concerning the GPS Disciplined Oscillator interfaces are also
located on the connector panel:
AUX DSUB9
Connects to AUX connector on MT1000A panel using J1705A
AUX Conversion Adaptor.
1pps Out The 1PPS signal is output. *
10MHz Out The 10 MHz clock signal is output. *
GPS
Lights in green when signals of four or more satellites are being
received.
OSC
Lights in green when the Rubidium oscillator stability reaches 10
-9
.
This lights within around ten minutes usually. However this varies
depending on ambient temperature.
1pps Sync In
The input connector of the external 1PPS reference signal for the
synchronization.
Antenna The connector for GPS antenna.
*: Signal which is synchronized with GPS or the signal inputted to 1pps Sync In.
