Symmetricom XLi 87-8028-2 w/New UPGRADED ublox GPS Receiver GUARANTEED GOOD SYNC [Used]

Guaranteed Sync Fix • WNRO Repair For All Symmetricom XLi Clocks • Resumes GPS Lock with Correct Time & Date Shown • Upgraded GPS Timing Receiver Option Card • Brand New Upgraded ublox GPS Module Installed • Suits Symmetricom XLi and XL-GPS Clocks • Part Number 87-8028-2

Note: This unit has been upgraded with a new, latest generation GPS receiver module from ublox. It is therefore unaffected by the September 18th 2022 week number rollover event that caused most XLi, XL-GPS and related receivers to fail to sync to GPS and/or to show an incorrect date. The new card is good for accurate GPS time and date reception until 2037.

Used and in good condition. Tested in a working XLi chassis and checked for good signal reception and time-lock (see screenshots). The original GPS module has been replaced with an latest-generation replacement card.  The old GPS cards reached end of life in September 2022 so this will allow you to enjoy faster time to sync and the correct date for years to come. Note that this is a multiple item listing so there will be very small (but non-performance affecting) cosmetic differences between the cards.

Description

The Microsemi/Symmetricom XLi Time and Frequency System is the most versatile and flexible solution for timing and synchronization requirements.

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).

• Better than 30 Nanoseconds RMS Accuracy to UTC
• Better than 1x10-12 Frequency Accuracy
• Supports Primary and Secondary Reference Inputs (GPS, Time Code, 1PPS)
