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 Timecode and Frequency outputs. The unit works as expected apart from the fact that it does not see incoming data on the RS-232 Serial I/O Port. It continues to send the current time at one second intervals in the outward direction only. So the serial port cannot be used to send commends to the receiver. This is probably not a major limitation as those commands can be entered via the keypad instead. The receiver is equipped with an upgraded OCXO high stability oscillator. The internal Lithium memory back up battery has just been replaced so that should not need further attention for some years. Only the right LCD has a backlight.
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.
