Introduction

Here's a lightly used GPS disciplined TCXO master clock unit with IRIG-B, Serial and 1 PPS outputs. The unit has been upgraded with a brand new latest generation GPS receiver from ublox giving super-quick signal lock (with a good antenna) and ensuring correct date display beyond 2035. The LCD display does not have a backlight (normal on these). It has been tested to confirm that it works as it should. The unit comes with a basic antenna to allow you to test the unit immediately upon receipt. For a permanent installation an outdoor antenna with a full view of the sky will be required. Operation from behind a windows is unlikely to be satisfactory. The antenna voltage is 5V so almost any professional GPS antenna of at least 26dB will suffice. The firmware has been upgraded to the latest version available at the time of listing.

Important...

This item includes an updated GPS card to replace the now-obsolete model originally installed by the factory.

There's a reason why you can find a lot of Arbiter GPS clocks being sold cheaply. That's because nearly all have failed GPS receiver cards that are reporting the wrong date (ie. nearly 20 years in the past). Sadly most other sellers somehow neglect to mention this in their enthusiasm to sell you a failed device. For the buyer, there's nothing more disappointing than finding after you've gone to all the trouble of rigging up your outdoor GPS antenna that the "precision" clock you just bought can't even show the right date. So before you buy a clock elsewhere, ask the seller for a photo of their clock showing the correct date and time.
