Function description:
The PHV power supply provides power to the transmit circuit and has six output channels:
AP100V, AN100V, PHV1P, PHV1N, PHV2P, and PHV2N.
Power is output by the PHV and then supplied to the transmit circuit after filtering.
2.2.2 Backend
The backend consists of the PC module and related circuits on the main board.
