Product Overview
The Epsilon™ Switch and Amplifier System (SAS) provides a cost-effective way to build a redundant clock system with very high operational availability with the Epsilon Clock series. The SAS achieves redundant time and frequency source monitoring with intelligent and automatic switching. This 19” wide rack mount device amplifies signals from the selected source and offers a large quantity of output channels.
The SAS receives and continuously monitors signals from 1 or 2 external clocks. Monitoring (voltage level checking and minimal period detection) is reported through dedicated LEDs.
When two external clocks are connected, the SAS offers a powerful redundant function by automatically selecting the best functioning source. Or the selection may be by-passed by the user to allow maintenance or single clock operation. In all cases, the distributed signals (Frequency, 1 PPS, TOD, and Status) are used from the same source clock. When in automatic mode, if the selected source is detected faulty, the SAS switches all the distributed signals to the other available source. The signals are amplified via analog electronic to ensure the lowest frequency phase noise and high RF isolation.
The SAS exists in two versions to handle the output capacity of the application. The SAS17 is 1 U high. The SAS36 is 2 U high.
