The ES-110 master clock, from time and signal distribution equipment manufacturer ESE, uses the GPS system to derive its central clock data rather than an internal crystal or some other source.
It will output a 10 MHz signal in square or sine waves. It also outputs ESE TC90 Time Code for remote time displays and a standard 1 PPS clock signal. Internal DIP switches allow configuration of timecode, time zone, antenna cable length compensation and the satellite tracking mode.
The front panel of the aluminum desktop box has an LED that indicates when a stable GPS lock has been obtained while another LED marks power.
There is a TNC antenna input as well on the back panel for the included 16-foot antenna or an optional “high-performance” GPS antenna.
