10.12 Reference Clock
M6100 >> Ref Clock
Configure the reference clock.
This reference signal for an outdoor BUC can be multiplexed on the L-band Tx interface.
A reference clock can be generated internally (default) or slave on an external source.
The internal reference clock is 10MHz.
The clock reference has the following specifications:
10MHz Ref Specifications
Internal clock reference Stability ± 2000 ppb over 0 to 70°C
Ageing ± 1000 ppb/year
Very High Stability (optional) Stability ±2x10e-9 over 0°C to 65°C
Ageing: ± 0.5 ppb/day
± 500 ppb/10 year
When an external source is selected, the following frequencies can be inserted.
1MHz, 2MHz, 5MHz, 10MHz or 20MHz.
Select the external clock reference for synchronization with other devices to have a higher stability
than the internal default stability.
