浅析3DX-50前面板控制技术

Analysis of 3DX-50 front panel control technology

目前越来越多的中波发射站使用了技术上较为新颖的3DX系列数字发射机产品,相比以前的DX系列,3DX的操作更为数字化。与传统DX系列的LED灯表示运行状态相比,3DX简化到只有一块14VGA显示面板,但数字化的前面板有着更多的操作功能,可通过旋转指轮和面板上的按钮直接切换激励器等完成复杂操作。以实际使用中的3DX-50数字中波发射机为例,分析了新一代数字发射机的前面板控制技术。

With the advancement of technology, more and more median wave transmitting stations use 3DX series digital transmitters with the relatively new technology. Compared to the previous DX series, the operation of 3DX is more digital. Compared to the traditional DX series with LED indicating the operating status, 3DX has only a 1/4VGA display panel, but its digital front panel has more features and operational functions. The complex operation may be achieved by rotating finger wheel and buttons on the panel. Through the actual application of 3DX-50 digital AM transmitter, the next-generation digital transmitter front panel control technology is analyzed in this paper.
