Important...

Upgraded unit!! This item includes a newly-installed factory-fresh 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 nowadays. 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 listings and use weasel words like "removed from a working installation", which translates as they've not bothered to do any testing, or they're off-loading the unit in the short window available before it fails.  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.

The remedy is to buy a clock that has a latest-generation GPS sub-system installed, as well as the latest firmware loaded in the clock unit. That way you'll be good for an accurate date for the best part of the next 20 years, assuming you and/or the clock are in service that long.

So before you buy a clock elsewhere, ask the seller for a photo of their clock showing the correct date and time. If they can't provide one then figure on dropping a hundred and fifty bucks on a new GPS card to be sent over from Asia, plus the ancillary interface board you'll probably need to install it, plus another hundred on the EPROM programmer needed to load the matching firmware.

Or you could just buy one that someone else has invested the time and effort to do all that work for you and who is willing to stand by their offer.

Introduction

Here's a lightly used GPS disciplined master clock unit with IRIG-B, Serial and 1 PPS outputs, that's in very good cosmetic condition. This one is the 'C' variant which boasts an impressive large red LED time display. The unit comes with a basic indoor antenna so it will acquire time for you right out of the box (when the antenna has a clear view of the sky when placed outdoors - indoor performance by a window is not guaranteed). The included antenna is intended to get you started and to allow you to check out the unit the day it arrives. A weatherproof external antenna with a full view of the sky is recommended for a permanent installation and for achieving the highest level of time accuracy as the unit will need to track 4+ satellites to achieve this - and I usually have some listed separately that would be ideal. Feel free to ask if you need a recommendation. Alternatively you can choose your own antenna as any 5V L1 antenna should work well. The firmware is the latest version available at the time of listing so you're running the most recent spec and won't have to worry about compliance with the 2007 DST changes, the 2019 GPS roll over, or recent leap second additions.

Description

The Arbiter Systems Inc. Model 1093B GPS Satellite-Controlled Clock is a GPS timing source for applications requiring an accurate time source with a better than 500ns accuracy. The Model 1093B features an LCD setup/status display and a keyboard for ease of inspection, configuration and operation.

Two pluggable terminal strip outputs provide unmodulated IRIG-B and 1 PPS. These outputs have substantial drive capability to easily drive multiple loads in parallel. These outputs are configurable to provide other output signals or an event-capture input.

Full details may be obtained from the User Manual
(https://www.prostudioconnection.net/1309/Arbiter_1092_93_manual.pdf)

The power supply requirements are universal, accepting 85 to 264 VAC or 110 to 350 VDC connected by a standard IEC-320 inlet on the rear panel.
