Here's a new old stock, never deployed Symmetricom XLi GPS Master Clock and function generator etc. The unit is is close to mint condition and the photos show the actual item for sale. The unused accessory pack is included and contains rack ears, network cable, serial cable, manual on CD and factory test results sheet. No antenna is included but I usually have matched 12V types listed separately - feel free to ask for a recommendation. This unit has the regular TCXO oscillator installed. It does have a GPS card installed but it is the earlier version (86-8013) which thinks it is in the previous GPS epoch so it reports a date that is 1024 weeks in the past. The fix for this is either to use IRIG as a timecode source or to change the card for the later 86-8013-2 type. The time and related functions are accurate included correct leap second adjustment. The NTP software based option is enabled (but with the same potential date limitation) but the other software based features are not activated. The firmware is version 1.8 which does not offer a web interface. I do not believe that the hardware will support later firmware code and any attempt to load a later version will most likely brick the unit and invalidate my warranty. No unpictured cables, accessories or documents are included. The unit has been tested and confirmed to operate as it should - a copy of the responses the various Function commmands is copied below.

Full details may be obtained from the User Manual (software version 1.8)

Description

One of the great design benefits of the XLi is that, because of its variety of option cards, a company can customize it to fit to their specific application needs. Whether your application demands redundancy in power supplies, GPS, or any other function, all it takes is the proper configuration of cards.

XLi Option Cards The wide range of XLi option cards make it easy to tailor your system to support nearly every possible output/input needed for time and frequency applications, by combining option modules, oscillator upgrades, and two GPS receivers per unit. Plug-and-play cards and built-in XLi option card recognition software lets you swap out modules without modifying your operating system.

Plug and Play Configuration Configuration recognition software automatically detects the unit’s setup, without modifications to the operating system, providing “plug-and-play" configuration capability for current and future application needs.

Freedom to Configure Modularity delivers the freedom to configure the XLi as a GPS timing receiver [GPS option not included], or a time code unit (TCU).

Seamless Integration The XLi seamlessly integrates into a network centric environment. The 10/100 Base-T interface is standard. Remote management is facilitated with the intuitive HTML web based interface as well as SNMP with an enterprise MIB. Command line interface is also supported via Telnet or the RS-232/422 serial port. The XLi can function as a Stratum 1 NTP server with addition of the NTS option.

Wide Range The standard XLi provides a wide range of time and frequency inputs and outputs such as: 1PPS output; time code input/output (IRIG A, B; NASA36) in both modulated (AM) and demodulated (DCLS) formats; programmable pulse rates; open collector alarm; front panel keypad and display; and more.

Modular Architecture for Easy Extensions The modular XLi architecture allows easy extension of the software and hardware in the field. Software updates are remotely administered. Existing and future hardware option modules can be added as needed by the user. The GPS timing interface is also modular which facilitates future upgrade to alternate Global Navigation Satellite Systems (GNSS), such as Galileo, when available.
