Description

Here's a lightly used TrueTime/Symmetricom XL-DC GPS time receiver/timecode generator in very good cosmetic condition. It has been tested for acquisition of GPS Sync and for good Time, Date, Timecode and Frequency outputs. The unit works as expected. The output from the console report obtained during testing is provided below. The receiver is equipped with a TCXO oscillator. The internal Lithium memory back up battery has just been replaced so that should not need further attention for some years. The right LCD displays has a backlight. Some small nicks and scratches (eg. on the rack ears) have been touched up using color-matched paint so that the unit should look close to pristine when seen in a rack at a normal viewing distance.

A basic test antenna is included to get you started - so you may need to take both receiver and antenna into the open air to test the device. The Antenna voltage is 5V so almost any good quality GPS antenna should work, but try and have at least 26dB of antenna gain if you want to replicate my test results. A Symmetricom AT575 type is recommended and I usually have some listed separately. Rack ears are included as shown. No printed manual is included but a copy may be downloaded from https://www.prostudioconnection.net/1112/xl-dc-manual.pdf if required. No unpictured cables, accessories or documents are included.
