Operations Manual, HPA2, Compact Outdoor SSPA
It is important to remember the requirement of a 10 MHz reference oscillator when operating
an SSPA with BUC (SSPB). If the 10 MHz reference is not present, the M&C will report a
BUC alarm and the SSPA module will mute. This ensures that no spurious or ‘off frequency’
transmission could originate from the amplifier.
Note: Unless the BUC has the built-in internal reference option, if there is an absence
of a 10 MHz reference signal on the IFL input there will be no output signal from the
SSPA.
5.1 ZBUC Features
This section describes the features available in the Teledyne Paradise Datacom ZBUC con-
verter. The ZBUC converter is available as an option for the Compact Outdoor SSPA, and is
available in four C-Band models, two Ku-Band models, one X-Band model, and one Ka-Band
model.
Table 5-1
shows the specifications for the respective models.
