The ES-410 generates a stable source of 10MHz and 1 PPS using GPS (Global Positioning System) satellites as a reference. The unit provides 10MHz in both Sine Wave and Square Wave (5 volt logic) form. Four Sine Wave and four Square Wave outputs are provided. The 1 PPS output is a 50% duty, 5 volt logic signal, positive-edge coinciding with the UTC seconds change. An ESE TC90™ Time Code output is also provided for driving remote time displays. A USB interface allows configuration of the Time Zone and other parameters, and outputs the time. If frequency distribution is needed, we offer the ES-210, a Quad 1x6 1/5/10 MHz Distribution Amplifier. The ES-210 provides four independent 1x6 Frequency DAs in a single rack-mount enclosure.
