ES-104E是一款實用和高性價比的網絡NTP時間服務器，可以為系統提供高精度的時間信號。它接收并且同步于GPS信號，NTP使用10/100 Base-T的以太網接口輸出。結構可以用于桌面，也可以機架安裝。如果gps失鎖，利用內部的溫度補償TVCXO自動走時。
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.
