External Oscillator

The external oscillator option is available on the GRX1200 Pro and GRX1200 GG Pro.
An external oscillator can be used to provide a better quality time signal to the GRX1200
Pro/GRX1200 GG Pro than the internal clock, for example, through the use of a rubidium or
caesium oscillator. The same external oscillator can also be used with a number of receivers
so that each GRX1200 Pro/GRX1200 GG Pro is guaranteed to be tracking satellites using
the same time signal. An external oscillator is attached to the GRX1200 Pro/GRX1200 GG
Pro via the port OSC.
The settings on this screen define the parameters for incoming external oscillator signals.
Refer to the GPS1200 User Manual for technical specifications of the external oscillator port
and the required cable.
