Introduction
Here's a lightly used GPS disciplined master clock unit with IRIG-B, Serial and 1 PPS outputs, that's in good cosmetic condition. The photos show the actual item for sale. The receiver has the Option 36 Quad BNC I/O jack panel installed; each BNC connector can be set to one of many options for pulse/frequency or timecode ouputs - see graphic below. T
he unit comes with a power cord attached and 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 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.

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.
