The RF signals generated by two exciters (in the redundant configuration) are first
attenuated by 6 dB to improve the uncoupling among the stages and then connected
to a coaxial relay commanded by the control unit. One of the two signals is closed on
a dummy load built into the machine whereas the other signal is connected to the
input splitter. The power of both signals is measured by specific directional couplers.
The RF signal of the selected exciter is divided into five branches, each of which is
passed to the input of an amplifying module.
