SAS-17E/36E Switch & Amplifier System

Overview

SAS-E is a high performance, highly manageable and reliable solution for distributing time and frequency signals for satcom, digital TV or audio broadcast, microwave links, satellite ground stations applications.

The Epsilon™ Switch and Amplifier System (SAS-E) provides a cost effective way to extend distribution of time and frequency signals (pulse, low phase noise frequency signal, Time of Day), as a signal amplifier. Thanks to analog amplification, SAS-E adds very little phase noise to the input frequency and ensures high RF isolation. It is therefore suitable for reference frequency distribution towards transmitters, up-converters, micro-wave links. Pulse regeneration is transparent to pulse duration and period: SAS-E is therefore suitable for distribution of any pulse encoded signal like 1 pps, DCLS IRIG, etc.

Large signal distribution

- Serial time code message (ToD) (RS-232 serial line)
- Customization available
Very low additional phase noise
Redundant source monitoring

Fast switching
External clock status (relay contact)
Remote management by SNMP/HTTP through Ethernet port

Details

The Epsilon™ Switch and Amplifier System (SAS-E) provides a cost effective way to extend distribution of time and frequency signals (pulse, low phase noise frequency signal, Time of Day), as a signal amplifier. Thanks to analog amplification, SAS-E adds very little phase noise to the input frequency and ensures high RF isolation. It is therefore suitable for reference frequency distribution towards transmitters, up-converters, micro-wave links. Pulse regeneration is transparent to pulse duration and period: SAS-E is therefore suitable for distribution of any pulse encoded signal like 1 pps, DCLS IRIG, etc.

SAS-E can also be combined with two clocks in order to build a redundant, highly reliable time and frequency distribution system. In such configuration, SAS-E constantly monitors available A and B inputs and automatically selects the appropriate source to be distributed on its outputs. Smart switching algorithm can be configured to determine which signal (amongst frequency, pulse, ToD, external alarm) should be monitored and trigger a switch. The automatic selection may also be bypassed by the user (on front panel or through network management) to allow maintenance or single-clock operation.

Setup, status, and alarms are accessible through network management, using 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 1U high SAS-17E distributes 8 frequency and 8 pulse signals. The 2U high SAS-36E distributes 16 frequency and 16 pulse signals.
