- RS-232 serial interface providing TOD strings in various formats and providing firmware update, local control and monitoring functionality
- Redundant power supplies (100 - 240 V AC, 50 - 60Hz / 100-200 V DC)
- 8x PPS PulsePerSecond outputs
- 2x Meinberg GPS Antenna System - with integrated downconverter for cable runs up to 700m without amplification and reliable robust signal reception characteristics
- 8x 10MHz TTL or low phase noise sinewave outputs
- Alarm relay output, changeover contact
- 2x independant high precision GPS clocks, each with its own ultra stable OCXO-HQ oscillator, providing excellent holdover performance and signal quality
Product Description
The integrated network management processor supports remote control and monitoring. Two serial ports offer local control and monitoring capabilities and can be used for generating serial time strings in various formats to feed TOD information into a wide range of devices.
The Meinberg RSC switchover logic ensures that the time and frequency synchronization signal generation from the two GPS receivers is automatically switched to the output connectors based on the synchronization state of the receivers. A manual override is possible both locally by using the front panel controls and remotely using the integrated network control and monitoring processor.
