4、高精度的时间同步、信号输出与守时技术;
5、可提供多路脉冲信号(1PPS mso-hansi-font-family:"Times New Roman"">、1PPM "Times New Roman"">、1PPH、事件,空接点、差分、TTL mso-hansi-font-family:"Times New Roman"">、5V/24V "Times New Roman"">有源)、IRIB-B "Times New Roman"">信号(TTL、422 mso-hansi-font-family:"Times New Roman"">、232 "Times New Roman"">、AC)、时间报文(RS232 mso-hansi-font-family:"Times New Roman"">、RS422/485 "Times New Roman"">)、DCF77 "Times New Roman"">信号;
6、采用1U mso-hansi-font-family:"Times New Roman"">或2U 19” "Times New Roman"">标准机箱,可单独组屏,便于维护和管理;
7、具有自复位能力,在因干扰造成装置程序出错时,能自动恢复正常工作;
8、选用高性能、宽范围的开关电源,工作稳定可靠;
9、接收天线采用了防雷设计、信号接收可靠性高,不受电厂/
