TrueTime Symmetricom XL-AK GPS Disciplined Pulse Frequency Generator Clock NEW!
( 362745971468) )
New/Unused • Mint Condition • Tested/Guaranteed • 5 Expansion Ports • Test Antenna & Rack Ears Included • 1PPS • IRIG-B • Programmable Pulse
A new old stock, unused, open box XL-AK GPS Disciplined Clock/Frequency/Pulse Generator. This unit has the additional 5 pulse/frequency output jacks installed. The output on each jack can be selected by means of an internal jumper from a wide range of possibilities and you are not limited to IRIG-B (see photo below). The clock shows the correct time and date and the internal Lithium battery is maintaining settings at the time of listing, but its longevity is not guaranteed. Full product details may be found in the User Manual here [https://www.prostudioconnection.net/1311/XL-AK_Manual.pdf]. A basic puck antenna is included to allow you to test the unit immediately upon receipt. For a permanent installation and accurate time/frequency generation a professional grade outdoor antenna with a clear view of the sky will be required. The antenna feed voltage on this unit is 5V so almost any professional conical type antenna should work fine. I can provide a recommendation if required. Note that the serial cable may be shorter than shown as some units shipped with a one foot cable (which I expect should not be a material issue as almost all computer serial ports are 9 pins these days so most buyers will just discard the supplied DB9 to DB25 cable in favor of a DB9 to DB9 null modem cable instead.)
The rack-mount XL-AK GPS receiver provides ultra-precise time and frequency. This configurable instrument provides timing outputs to within 40 nanoseconds rms of UTC/USNO and frequency outputs accurate to less than 1x10-12, even when tracking satellites with Selective Availability (SA) implemented. User-configurable outputs provide significant flexibility in configuring the XL-AK as a central source for IRIG time codes or output pulses.
