Does the new generation S-band weather radar circuit have to be powered by dual channels?

I have to. The new generation S-band weather radar circuit can only be used normally by using two AC mains plus standby generator sets, so the new generation S-band weather radar circuit must be powered by two sources. The circuit of the new generation S-band weather radar often works at the frequency of 2-4GHz, which involves the signal generation device of the S-band weather radar test system, including the phase-locked loop, direct digital frequency synthesizer, mixer, filter network, numerical control amplifier and other equipment.
