Introduction
Here's a rare chance to acquire an unused upgraded XL-GPS time receiver and timecode/frequency generator. This is a new-old-stock unit that was removed from the sealed factory packaging only to confirm that it works as it should. The console output from my testing session is copied below. None of the software based optional features are enabled so this is not an NTP server. The only modification made to the unit was to replace the OEM Furuno GPS receiver with a factory-fresh iLotus replacement, as the Furuno card has limited life remaining. The factory accessory pack is included and this contains a pair of rack ears as well as the normal ethernet and serial cables. Note that
no antenna is included
, but I have the OEM factory type listed separately (search for AT575 12V). The antenna voltage is 12V so you will need an appropriately matched antenna to receive time from the GPS system. The photos show the actual item for sale.
The listing comprises the items shown in the images only; no additional accessories, cables, documents or software included.  Item ships in plain packaging.

Nanosecond Accuracy
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.
Versatile Measurement
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.
Bottom Line
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.
