高频发射机系统如图所示，主要由高频放大、槽路、冷却系统和供电系统四部分组成。

高频放大部分是由固态宽频带放大器、电子管构成的二级放大系统;供电系统主要负责电子管的灯丝、栅极、帘栅极、阳极和宽频带放大器的供电;加之整个发射机是一个以分布参数为主的系统，因而槽路是改善发射机参数和性能的重要组成部分。

考虑到发射机工作在一个有高压、低压、交流、直流、脉冲和模拟信号混合的电磁环境中，为保证控制系统的稳定性和可靠性，采用了西门子S7-300系列的PLC、触摸屏，并结合Ethernet(工业以太网)技术设计了NB2发射机控制系统，实现了发射机的远程控制。

Ethernet网络是采用商业以太网通信芯片和物理介质，利用以太网交换机实现各设备间的点对点连接的工业以太网技术。

能同时能支持10M和100M的以太网的商业产品。它的一个数据包最多可达1500字节，数据传输可达10Mbps或100Mbps;从而实现数据的高速传输

The high frequency transmitter system is shown in the figure, which is mainly composed of four parts: high frequency amplification, trough, cooling system and power supply system.

The high frequency amplifier part is a two-stage amplifier system composed of solid-state broadband amplifier and electron tube. The power supply system is mainly responsible for the power supply of the filament, grid, screen grid, anode and broadband amplifier of the electron tube. In addition, the whole transmitter is a system based on distributed parameters, so the channel is an important part of improving the parameters and performance of the transmitter.

Considering that the transmitter works in an electromagnetic environment with high voltage, low voltage, AC, DC, pulse and analog signals mixed, in order to ensure the stability and reliability of the control system, Siemens S7-300 series PLC, touch screen, and combined with Ethernet(Industrial Ethernet) technology designed the NB2 transmitter control system. The remote control of transmitter is realized.

Ethernet network is an industrial Ethernet technology that uses commercial Ethernet communication chips and physical media, and uses Ethernet switches to realize point-to-point connections between devices.

Commercial products that can support both 10M and 100M Ethernet. Its one packet can be up to 1500 bytes, and the data transfer can be up to 10Mbps or 100Mbps; Thus the high-speed data transmission is realized
