DescriptionSymmetricom XLi Series Time & Frequency System.
Key Features12 channel GPS receiver with TRAIM Better than 30 nanoseconds RMS accuracy to UTC Better than 1x10-12 frequency accuracy Supports primary and secondary reference inputs (GPS, time code, 1PPS) Configurable with dual redundant GPS receivers in one chassis Standard 10/100 Base-T network port HTTP, Telnet, SNMP with MIB standard Vacuum fluorescent display and keypad Time code reader/generator (IRIG A,B; IEEE 1344; NASA 36) AM and DC Auxiliary reference input supports lock to external cesium to enhance holdover Standard outputs: 1PPS, selectable pulse rates and alarm
Key BenefitsIntuitive web based management Completely modular with plug-and play capability Numerous field-upgradeable, plug-in option cards available Flash memory for remote software upgrades
OverviewThe modular ultra precision XLi Time and Frequency System is the most versatile and flexible solution for timing and synchronization requirements. The XLi is completely modular with a variety of option cards that are easily configured by the user. The wide range of option cards make it easy to tailor your system to support nearly every possible output/input needed for time and frequency applications, by combining up to ten option modules (2U chassis), oscillator upgrades, and two GPS receivers per unit.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. Modularity delivers the freedom to configure the XLi as a GPS timing instrument, or a time code unit (TCU). Deploy the Symmetricom® GPS technology to generate ultra high precision time and frequency outputs for a wide range of synchronization requirements, or leverage Symmetricom’s years of expertise in Time Code technology, which is built into the heart of the XLi system.The XLi seemlessly 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.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; IEEE 1344; NASA36) in both modulated (AM) and demodulated (DCLS) formats; programmable pulse rates; open collector alarm; front panel keypad and display; and more.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.
