Connector Descriptions
10 MHz REF OUT This rear-panel port outputs a 10 MHz reference. This signal is phase locked to the
signal applied to the REF IN port. All clocks (Bit, Symbol, and Frame) are
derived from or phase locked to this signal.
If the REF UNLOCK indicator is lit, the output frequency may not be accurate.
Operating Considerations
Nominal output level: >+5 dBm
Output impedance = 50
Ω
Frequency stability = the same as the signal applied to the REF IN connector
(typically needs to be within
±5 ppm of the selected Reference frequency).
