Spectracom 8183 Netclock GPS Satellite Atomic Clock Time Receiver Syncs to GPS but 10MHz Oscillator Needs Attention • Includes Antenna and AC Power Supply Photos show the actual item for sale The clock comes with everything you need to receive accurate time from the GPS system. I am including a basic indoor antenna, and a power supply to get you started. A copy of the manual is not included, however this may be downloaded if needed. Note however that the 10MHz oscillator is only partially working. The Temperature Compensation arrangement doesn't seem to be responding to the GPS signal so the frequency is less accurate than spec. If you need an accurate IRIG/1PPS/RS-232 clock then the other functions should work fine for you. If you need a laboratory grade 10MHz oscillator then you will need to fix the oscillator module unit. The basic indoor antenna is included to allow you to test it straight out of the box. For a permanent installation and quicker sync times, a quality outdoor antenna with a full view of the sky is highly recommended. I usually have some suitable antennae listed and a downlead can be obtained from a cable fabricator. The unit's home timezone and other parameters can easily be changed by using Windows Hyperterminal via the serial management port (serial cable not included). You will therefore need a computer with a serial port and appropriate cable if you want to change the unit's configuration. The Log File from my testing is reproduced at the end of the listing if you wish to see the test results for yourself. This is a very capable piece of equipment and you can find all functionality documented in the User Manual.

The NetClock/GPS receives and recovers time information from the Global Positioning System (GPS) constellation of satellites. The GPS constellation consists of 24 satellites placed in 6 orbital planes spaced equally around the equator and inclined at a 55-degree angle. This design assures reliable worldwide coverage 24 hours a day. Each satellite contains a redundant system of highly accurate and stable atomic clock sources. The satellite’s timing, orbital position and other system parameters are monitored and controlled by ground stations maintained by the US Department of Defense and US Naval Observatory. The NetClock/GPS Master Clock provides timing outputs accurate to within 100 microseconds of UTC. Standard Master Clock outputs include RS-232, RS-485, IRIG B/E and a one pulse per second. The NetClock/GPS is ideally suited as a Master Clock in all applications requiring an accurate and traceable time source. Typical applications include computer network timing, utility billing, financial transactions, public safety and transportation DOL SPECTRACOM CORPORATION NETCLOCK GPS SOFTWARE VERSION 1.02 DATE: NOVEMBER 04, 1996 16:28:17 UNIT STARTED 21:09:33 2014-04-27 FRONT PANEL VERSION 1.01 IRIG VERSION 1.01 SERIAL PORT 1 VERSION 1.01 SERIAL PORT 2 VERSION 1.01 REMOTE PORT 1 VERSION 1.01 REMOTE PORT 2 VERSION 1.01 TIME= 08:20:43 DATE= 2014-04-28 D/A= 8082 FREQ ERROR= -8.82E-07 FREQ CNT= 999,999,118 TIME= 08:20:43 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00131 FREQ ADJ CNT= 00131 AVG FREQUENCY ERROR= -8.82E-07 NEW D/A= 8083 TIME= 08:22:25 DATE= 2014-04-28 D/A= 8083 FREQ ERROR= -8.81E-07 FREQ CNT= 999,999,119 TIME= 08:24:07 DATE= 2014-04-28 D/A= 8083 FREQ ERROR= -8.82E-07 FREQ CNT= 999,999,118 TIME= 08:25:49 DATE= 2014-04-28 D/A= 8083 FREQ ERROR= -8.82E-07 FREQ CNT= 999,999,118 TIME= 08:25:49 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00132 FREQ ADJ CNT= 00132 AVG FREQUENCY ERROR= -8.82E-07 NEW D/A= 8084 TIME= 08:27:31 DATE= 2014-04-28 D/A= 8084 FREQ ERROR= -8.81E-07 FREQ CNT= 999,999,119 TIME= 08:27:32 DATE= 2014-04-28 3D FIX ACQUIRED LATITUDE= N 38 54 04.189 LONGITUDE= W 077 24 00.588 HEIGHT= +00135.52 METERS TIME= 08:29:13 DATE= 2014-04-28 D/A= 8084 FREQ ERROR= -8.83E-07 FREQ CNT= 999,999,117 TIME= 08:30:55 DATE= 2014-04-28 D/A= 8084 FREQ ERROR= -8.82E-07 FREQ CNT= 999,999,118 TIME= 08:30:55 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00133 FREQ ADJ CNT= 00133 AVG FREQUENCY ERROR= -8.82E-07 NEW D/A= 8085 TIME= 08:32:22 DATE= 2014-04-28 3D FIX ACQUIRED LATITUDE= N 38 54 04.248 LONGITUDE= W 077 24 00.615 HEIGHT= +00115.09 METERS TIME= 08:32:37 DATE= 2014-04-28 D/A= 8085 FREQ ERROR= -8.80E-07 FREQ CNT= 999,999,120 TIME= 08:34:19 DATE= 2014-04-28 D/A= 8085 FREQ ERROR= -8.81E-07 FREQ CNT= 999,999,119 TIME= 08:36:01 DATE= 2014-04-28 D/A= 8085 FREQ ERROR= -8.79E-07 FREQ CNT= 999,999,121 TIME= 08:36:01 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00134 FREQ ADJ CNT= 00134 AVG FREQUENCY ERROR= -8.80E-07 NEW D/A= 8086 TIME= 08:37:43 DATE= 2014-04-28 D/A= 8086 FREQ ERROR= -8.79E-07 FREQ CNT= 999,999,121 TIME= 08:39:25 DATE= 2014-04-28 D/A= 8086 FREQ ERROR= -8.80E-07 FREQ CNT= 999,999,120 TIME= 08:41:07 DATE= 2014-04-28 D/A= 8086 FREQ ERROR= -8.79E-07 FREQ CNT= 999,999,121 TIME= 08:41:07 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00135 FREQ ADJ CNT= 00135 AVG FREQUENCY ERROR= -8.79E-07 NEW D/A= 8087 TIME= 08:42:49 DATE= 2014-04-28 D/A= 8087 FREQ ERROR= -8.80E-07 FREQ CNT= 999,999,120 TIME= 08:44:31 DATE= 2014-04-28 D/A= 8087 FREQ ERROR= -8.78E-07 FREQ CNT= 999,999,122 TIME= 08:46:13 DATE= 2014-04-28 D/A= 8087 FREQ ERROR= -8.79E-07 FREQ CNT= 999,999,121 TIME= 08:46:13 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00136 FREQ ADJ CNT= 00136 AVG FREQUENCY ERROR= -8.79E-07 NEW D/A= 8088 TIME= 08:47:55 DATE= 2014-04-28 D/A= 8088 FREQ ERROR= -8.80E-07 FREQ CNT= 999,999,120 END OF LOG TIME= 08:49:37 DATE= 2014-04-28 D/A= 8088 FREQ ERROR= -8.85E-07 FREQ CNT= 999,999,115 TIME= 08:51:19 DATE= 2014-04-28 D/A= 8088 FREQ ERROR= -8.85E-07 FREQ CNT= 999,999,115 TIME= 08:51:19 DATE= 2014-04-28 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00137 FREQ ADJ CNT= 00137 AVG FREQUENCY ERROR= -8.83E-07 NEW D/A= 8089 DSS CHAN VID MODE STREN STAT 01 05 08 151 A0 02 21 00 131 00 03 15 08 155 A0 04 18 00 119 00 05 29 08 117 A0 06 09 08 036 A0 07 02 08 099 A0 08 26 08 195 A0 STAT TIME= 08:52:48 DATE= 2014-04-28 TRACKING 6 SATELLITES 3D FIX LATITUDE= N 38 54 04.226 LONGITUDE= W 077 24 00.585 HEIGHT= +00123.30 METERS TIME REMAINING: GPS LOCK= 00:15:00 TIME SYNC= 02:00:00 EVENT RELAY = OFF ALARM RELAYS: MAJOR= OFF MINOR= OFF ACTIVE ALARMS: NONE TIME= 19:20:50 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=OFF ACTIVE ALARMS: MAJOR FREQUENCY CPU ALARM TIME= 20:20:20 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=OFF ACTIVE ALARMS: MAJOR FREQUENCY TIME= 20:21:20 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=OFF ACTIVE ALARMS: MAJOR FREQUENCY CPU ALARM TIME= 20:47:39 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=ON ACTIVE ALARMS: MAJOR AND MINOR FREQUENCY IN TEST MODE TIME= 20:48:09 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=OFF ACTIVE ALARMS: MAJOR FREQUENCY TIME= 20:48:11 DATE= 2014-04-27 STATUS CHANGE EVENT RELAY =OFF ALARM RELAYS: MAJOR=ON MINOR=OFF ACTIVE ALARMS: MAJOR FREQUENCY CPU ALARM END OF LOG Powered by eBay Turbo Lister The free listing tool.
