Description

Here's a lightly used TrueTime/Symmetricom GPS-DC GPS time receiver/timecode generator in good cosmetic condition. It has been tested for acquisition of GPS Sync and for good Date, Timecode and Frequency outputs. The unit works as expected - see console port output obtained during testing below. 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.

The unit has four option cards installed: two 86-379 quad IRIG-B output cards.  These have Triax connectors so BNC jacks will not connect to them hence they are untested. The BNC IRIG-B output works as expected. Plus two 86-378 RS-422/IRIG-B interface cards (untested by me).

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 (of a very similar device's manual) may be downloaded from https://www.prostudioconnection.net/1112/xl-dc-manual.pdf if required. No unpictured cables, accessories or documents are included.
