GPS-DS-10

Product catalog summary

Overview
The GPS-DS-10 is a multi-output Time & Frequency Signal Generator designed by Digital Instruments S.r.l. It features two independent GPS receivers with high-stability OCXO oscillators, providing redundancy and reliability. The device offers 10 MHz and 1PPS outputs, with NTP capabilities via an Ethernet interface, making it a Stratum-1 NTP server when GPS-locked. The system includes dual redundant hot-swappable power supplies and user-definable switching policies.

Switch Unit Features

10 independent BNC connectors for 10 MHz frequency outputs at 13 dBm power level.
10 independent PPS connectors with TTL level, terminated at 50 Ohm.
7 dry contacts for electrical signaling and 4 photo-coupled inputs for remote control.
RS232 serial connection and Ethernet 10/100 network connection with SNMPv1 protocol support.
Integrated web server for management.
Operates on AC 85-265 Vac, 50/60 Hz, and fits a 19'' 1U rack.

Generator Module Features

High-stability OCXO oscillator with a frequency drift of +/- 1*10-10 per day.
12-channel GPS receiver with automatic tracking and error management.
10 independent sine wave outputs at 10 MHz frequency, each with 13 dBm power level.
10 PPS outputs with TTL level, terminated at 50 Ohm.
Removable drawer container measuring 120x220 mm.
