Photos show the actual item for sale
A very lightly used XL-AK GPS Disciplined Clock/Frequency/Pulse Generator with a TCXO oscillator installed. The five BNC IRIG/pulse output BNC connectors can be set for a wide range of pulse frequencies via internal jumpers (see photo). The output from the console port obtained during testing is copied below. The photos show the actual item for sale. A few small nicks and scratches have been retouched so the item will look pristine when installed in your rack. The clock shows the correct time and date and the internal 3.7V Lithium battery for maintaining settings has just been replaced with a fresh cell so you should be good for some years to come. Full product details may be found in the User Manual at 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. I can provide a recommendation if required - the antenna voltage is 5V so almost any professional grade outdoor antenna can be used. The LCD display does have a backlight.
Description
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.
