Safran CDM-5 Information:
The GSG-8 contains an Safran CDM-5 to distribute a 10 MHz reference clock and 1PPS signals throughout the integrated SDRs. The CDM-5 is added to your GSG-8 to create a maintenance-free timing mechanism. If necessary, it also contains 2 LED indicator lights to provide information about the current oscillator validity. (See chart below). The CDM-5 has an Operating Modes switch (INT or EXT).

orolia GSG-8 Series Advanced GNSS Simulator - Mechanical
1To use the CDM-5 as the simulator’s reference clock, the operating modes switch must be set to INT. This is the default setting and will be preconfigured on your GSG-8. orolia GSG-8 Series
Advanced GNSS Simulator - Mechanical 2*PPS indicates LED is flashing at 1 pulse-per-second. A 4-second alternating color pattern occurs during normal boot sequence.
To use the CDM-5 to provide the 10 MHz and PPS signals of an external reference to the simulator, you must turn the Operating Modes switch to EXT, connect your 10 MHz reference clock to the CLK connector of the CDM-5, and connect your 1PPS source signal to the PPS IN connector of the CDM-5.
