rubidium frequency standard

The master clock in the SIM900 is based on a low-noise crystal oscillator. In its default configuration, the PRS10 uses pins #4 and #7 for the RS-232 interface to provide a complete set of systems diagnostics and control. The optional timebase input (option 02) permits phase-locking the master clock to an external 10 MHz reference (like the SIM940 Rubidium Standard) through a rear-panel BNC input. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. Rear-panel 10 MHz inputs and outputs are provided allowing the SR865A to be locked to an external frequency reference (such as the FS725 10 MHz Rubidium Frequency Standard). atomic clocks such as the Rubidium standard are as of 2018 also common.
