ES-104E是一款实用和高性价比的网络NTP时间服务器，可以为系统提供高精度的时间信号。它接收并且同步于GPS信号，NTP使用10/100 Base-T的以太网接口输出。结构可以用于桌面，也可以机架安装。如果gps失锁，利用内部的温度补偿TVCXO自动走时。

The ES-104E provides a practical method of putting accurate time information onto a network. The unit receives GPS time using the supplied antenna. The NTP output is provided on a 10/100 Base-T Ethernet connector. The ES-104E is housed in a rugged black anodized desktop enclosure. A voltage-controlled temperature-compensated crystal oscillator is used to maintain the accuracy of the time code outputs when lock is lost.
