Symmetricom, Inc. has readied a new time and frequency receiver, the XL-GPS. It provides accurate time and frequency signals and a cost-effective global positioning system to support many applications including test and measurement, data acquisition, central timing systems, process automation, range timing, and the power industry. The XL-GPS is a rack-mount instrument with an internal, time-optimized GPS satellite receiver that locks to signals from the satellite atomic clocks. The XL-GPS provides a variety of signal outputs accurately synchronized to Coordinated Universal Time (UTC) with the long-term stability of an atomic clock.

The XL-GPS Time and Frequency Receiver is a versatile, 1U instrument with user-configurable inputs and outputs to suit application requirements. Signal outputs include a 1 pulse-per-second (PPS), IRIG-B time code, and rate outputs to 10 MPPS. Management and control is facilitated with a network interface. An optional expansion module provides additional outputs. Furthermore, it can be optionally configured to function as a Network Time Protocol (NTP) server for computer synchronization.

Key features of the XL-GPS time and frequency receiver include accuracy to within 30 nanoseconds RMS UTC(USNO), frequency stability better than 1x10-12 (long term) and high-performance, 12-channel GPS receiver with TRAIM (Time Receiver Autonomous Integrity Monitoring) to protect against faulty satellite signals. The XL-GPS time and frequency receiver will be available next month.
