Description

Lightly used, in excellent cosmetic condition and fully working, including showing a correct date. The IRIG-B, 10MHz, 5MHz and 1MHz outputs have been tested as being good. I didn't see a 1PPS output so maybe that wasn't ordered by the original buyer.  The optional Frequency Measurement feature is installed. A copy of the console port output taken during testing is provided below.  The photos show the actual item for sale. A basic antenna is included to allow you to test the item out of the box although you will probably need to take both the receiver and the antenna outdoors to test. The Antenna voltage is 5V so almost any professional conical type antenna will probably work. Note that the antenna needs a clear and complete view of the sky for the unit to function to full specification. Rack ears are included as shown. The internal Lithium memory back up battery has just been replaced so should not need attention for some years. The photos show the actual item for sale. No printed manual is included but a copy may be downloaded from https://www.prostudioconnection.net/1112/xl-dc-manual.pdf if required.
