Operations Manual: Functional Description
Engineered to Endure
The internal 10 MHz reference signal meets the minimum phase noise requirements
listed in
Note:
If an external 10 MHz reference signal is applied to a unit with the optional internal
10 MHz reference signal, the external signal has priority. When the external signal is
removed from such units, the system automatically reverts to the internal 10 MHz
signal, requiring no additional user input.
Input to the IBUC includes DC voltage (via the J3 connector) or DC voltage for low-
power units and FSK signal via the J1 connector. The input (L
-
band, 10 MHz, and DC
via coaxial cable) is routed to the demultiplexer circuitry where the various signals are
split off and routed to the appropriate circuits within the IBUC. The input voltage from
the demultiplexer circuitry is routed to the power supply and the FSK signal is routed
to the M&C card.
