Arbiter Systems 1093C Opt 28 UPGRADED GPS Atomic Time Clock Receiver LED Display [Refurbished]

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. A factory-fresh latest-generation high sensitivity GPS module has just been installed and this achieves sync to GPS within seconds of power up (with a good antenna). The new GPS receiver will show the correct date beyond 2040. The receiver has the Option 28 Power System Time, Frequency, and Phase Monitor installed, but the interconnection cable is not included so I have not tested this function, although I have no reason to believe that it is not working as it should. It also has Option 19 - a second RS-232 port - installed. 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 photos show the actual item for sale.

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.

I/O Configuration:

Connectors:

Two standard: one IRIG-B Unmodulated and one 1 PPS; Type: bus driver, 5 V CMOS; 10 ohms source impedance; ±75 mA drive capability; pluggable terminal strip.

Programmable Pulse Output:

One programmable output pulse (by a jumper connection) that may be output on a terminal strip connector or the AUX OUT pin on either RS-232 Port.

Four modes:

• Every 1 to 60,000 seconds, starts top of the minute
• Hourly at a specified offset
