The Epsilon™ Switch and Amplifier System (SAS-E) provides a cost-effective way to build a time and frequency distribution system. It accomodates redundant clocks with very high operational availability. The SAS-E achieves redundant time and frequency source monitoring through intelligent and automatic switching. This 19" wide rack mount device amplifies signals from the selected source and offers a large quantity of output channels. 

When two external clocks are connected, the SAS-E offers a powerful redundant function by automatically selecting the best functioning source. The selection may also be bypassed by the user to allow maintenance or single-clock operation. In all cases, the distributed signals (Frequency, 1PPS, ToD, and Status) are used from the same source clock. When in automatic mode, if the selected source is detected as faulty, the SAS-E switches all the distributed signals to the other available source. The signals are amplified using analog electronics to ensure the lowest frequency phase noise and high RF isolation.

Setup, status, and alarms are accessible by remote control through any web browser and/or through SNMP protocol. Monitoring (voltage level checking and minimal period detection) is reported through dedicated LEDs.

 The SAS-E is available in two versions to handle the output capacity of the application.

• The SAS-17E is 1 U high with signals and outputs as shown below
• The SAS-36E is 2 U high with signals and outputs as shown below
