Redundant Configuration Application
Refer to Figure 16. The SSPA has built-in Waveguide switch control and
indicator functions. Two SSPAs can be configured in a 1:1 redundant
system without an external system controller. In Redundant configuration
one amplifier constantly monitors the operation of the other amplifier so
that if the online amplifier becomes faulted, the backup amplifier will take
its place. This automatic switching requires that the backup amplifier
must be operational (not faulted) and in
automatic mode . Please refer to
the system manual for more details on redundant switching.
Note
The waveguide switch interface J6 provides the control and
monitoring of two waveguide switches SW1 and SW2.
Only SW1 can be used in a 1:1 redundant configuration.
SW2 can be added as an offline switch. It cannot be
configured as a 1:1 or 1:2 system with 3 HPA.
Note
The Auto mode can be selected via serial interface. Please
refer to the Protocol and Operation chapters for more
details.
