High Value, Network Managed Time and Frequency Receiver
At the core of the XL-GPS is Symmetricom’s advanced XLi technology which assures ultra accurate and reliable performance. The XL-GPS offers cost-effective functionality and ease-of-use where the XLi offers modularity and extensibility through multiple option slots and modules.
The XL-GPS clock is accurate to within 30 nanoseconds to Coordinated Universal Time (UTC) when synchronized to the integrated 12 channel GPS satellite receiver. Ultra-stable frequency outputs are accurate to less than 1x10-12 long term. For improved short-term stability and holdover performance, an oven oscillator option is available. A time code input provides an alternate or back-up reference to GPS.
Easy Monitoring and Control
The XL-GPS provides multiple interfaces to facilitate easy monitoring and control. The built-in network interface supports remote operation via telnet and SNMP. Local control is supported via a RS-232/422 port and a front panel LCD display and keypad is provided for direct control. A discrete alarm output is also provided to drive an alarm monitoring system.
Variety of Outputs
The XL-GPS provides a variety of standard time and frequency outputs including a 10 MHz frequency reference, one pulse-per-second (1PPS), time codes (IRIG A, B; IEEE 1344 and NASA 36), pulse rates up to 10MPPS, and an open collector alarm output. A rear panel option bay supports expansion of standard time and frequency outputs with a hardware option module. A Programmable Pulse Output (PPO) is available as a software option. The front panel display provides operators with “at-a-glance” system status.
The versatile XL-GPS supports measurements of time and frequency signals relative to its very accurate clock. The Frequency Measurement (FM) option supports analysis of 1, 5, 10 MHz frequencies. The Time Interval/Event Timing (TI/ET) supports precise event time tagging and time interval measurements to 5 nanosecond.
The XL-GPS has a strong set of core features that can be extended with a number of versatile options to meet the needs of a wide range of applications.
