串行调制编码 在新的发射机中,使用了数字串行自适应调制(DSAM)技术,它为AM调制控制提供了许多好处。在这种系统中,输入信号加于激励器中的一个A/D转换器,激励器的输出是数字的数据流,它通过一个高速数据电缆送至每一个调制编码器。每一个调制编码器用这个数字数据流向各个大台阶RF放大器和二进制RF放大器提供on/off信号。 使用这种串行通信系统可以提
Serial Modulation Coding In the new transmitter, digital serial adaptive modulation (DSAM) technology is used, which offers many benefits for AM modulation control. In this system, the input signal is applied to an A / D converter in the exciter. The output of the exciter is a digital data stream that is sent to each of the modulation encoders via a high-speed data cable. Each modulation encoder uses this digital data stream to provide on / off signals to each of the large stage RF amplifier and the binary RF amplifier. Use this serial communication system can mention
