Spectracom 8183 Netclock GPS Satellite Atomic Clock Receiver 10MHz IRIG-B 1PPS Includes Test Antenna and 120V Power Supply Photos show the actual item for sale Overview The clock comes with everything you need to receive accurate time from the GPS system. I am including an indoor test antenna, and a power supply to get you started. A copy of the manual is not included, however this may be downloaded if needed. I placed the antenna and receiver outdoors (so that the antenna would have a full view of the sky) achieved time sync in less than 30 minutes. I also tested with a professional grade outdoor antenna - the results of those tests are shown in the log files reproduced at the end of the listing. The basic indoor antenna is included to allow you to test it straight out of the box, but for a permanent installation an outdoor antenna with a full view of the sky is recommended. I usually have some suitable antennae lisited, 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 from the factory default values. Description The Spectracom NetClock/GPS Master Clock is a precise, traceable time provider. 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. Photos show the actual item for sale 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 STAT TIME= 13:28:43 DATE= 2015-09-06 TIME SYNC STATUS= OK GPS LOCK STATUS= OK GPS SIGNAL= QUALIFIED OSCILLATOR STATUS= LOCKED EVENT RELAY = OFF ALARM RELAYS: MAJOR= OFF MINOR= OFF ACTIVE ALARMS: NONE GSS TRACKING 8 SATELLITES GPS STATE= 3D-FIX DOP= 02.9 LATITUDE= N 38 54 04.141 LONGITUDE= W 077 24 00.697 HEIGHT= +00082.39 METERS QUALITY= PASSED CHAN VID MODE STREN STAT 01 04 08 050 A2 02 11 08 052 A2 03 28 08 040 A2 04 30 08 047 A2 05 19 08 051 A2 06 07 08 050 A2 07 08 08 052 A2 08 01 08 051 A2 DAL TIME= 49:50:32 DATE= 8224-32-32 STATUS CHANGE EVENT RELAY = ON ALARM RELAYS: MAJOR= OFF MINOR= ON ACTIVE ALARMS: NONE TIME= 87:68:82 DATE= 8272-47-78 STATUS CHANGE EVENT RELAY = OFF ALARM RELAYS: MAJOR= OFF MINOR= OFF ACTIVE ALARMS: NONE TIME= 49:51:53 DATE=12848-50-48 STATUS CHANGE EVENT RELAY = OFF ALARM RELAYS: MAJOR= OFF MINOR= OFF ACTIVE ALARMS: NONE TIME= 19:29:28 DATE= 2015-09-05 STATUS CHANGE EVENT RELAY = OFF ALARM RELAYS: MAJOR= ON MINOR= OFF ACTIVE ALARMS: MAJOR FREQUENCY TIME= 19:40:45 DATE= 2015-09-05 STATUS CHANGE EVENT RELAY = OFF ALARM RELAYS: MAJOR= ON MINOR= OFF ACTIVE ALARMS: MAJOR FREQUENCY TIME= 20:18:48 DATE= 2015-09-05 STATUS CHANGE EVENT RELAY = OFF ALARM RELAYS: MAJOR= OFF MINOR= OFF ACTIVE ALARMS: NONE END OF LOG DOL Spectracom Corporation Netclock/GPS Model 8183 Software Version 2.07 Date: September 02, 2000 14:31:28 Unit Started 19:29:28 2015-09-05 Front Panel Version 1.02 IRIG Version 1.02 Serial Port 1 Version 2.03 Serial Port 2 Version 2.03 Remote Port 1 Version 2.03 Remote Port 2 Version 2.03 GPS Receiver = 8 Channel GT Version 2 TIME= 12:56:42 DATE= 2015-09-06 D/A= 8C48 FREQ ERROR= -4.00E-09 FREQ CNT= 999,999,996 TIME= 12:58:24 DATE= 2015-09-06 D/A= 8C48 FREQ ERROR= -3.00E-09 FREQ CNT= 999,999,997 TIME= 12:58:24 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00195 FREQ ADJ CNT= 00183 AVG FREQUENCY ERROR= -6.00E-09 NEW D/A= 8C5D TIME= 13:00:06 DATE= 2015-09-06 D/A= 8C5D FREQ ERROR= -2.00E-09 FREQ CNT= 999,999,998 TIME= 13:01:48 DATE= 2015-09-06 D/A= 8C5D FREQ ERROR= -4.00E-09 FREQ CNT= 999,999,996 TIME= 13:03:30 DATE= 2015-09-06 D/A= 8C5D FREQ ERROR= -7.00E-09 FREQ CNT= 999,999,993 TIME= 13:03:30 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00196 FREQ ADJ CNT= 00184 AVG FREQUENCY ERROR= -4.00E-09 NEW D/A= 8C6B TIME= 13:05:12 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= -5.00E-09 FREQ CNT= 999,999,995 TIME= 13:06:54 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= -2.00E-09 FREQ CNT= 999,999,998 TIME= 13:08:36 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= +6.00E-09 FREQ CNT= 1,000,000,006 TIME= 13:08:36 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00197 FREQ ADJ CNT= 00184 AVG FREQUENCY ERROR= +0.00E-09 NEW D/A= 8C6B TIME= 13:10:18 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= -1.00E-09 FREQ CNT= 999,999,999 TIME= 13:12:00 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= -7.00E-09 FREQ CNT= 999,999,993 TIME= 13:13:42 DATE= 2015-09-06 D/A= 8C6B FREQ ERROR= -5.00E-09 FREQ CNT= 999,999,995 TIME= 13:13:42 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00198 FREQ ADJ CNT= 00185 AVG FREQUENCY ERROR= -4.00E-09 NEW D/A= 8C79 TIME= 13:15:24 DATE= 2015-09-06 D/A= 8C79 FREQ ERROR= +4.00E-09 FREQ CNT= 1,000,000,004 TIME= 13:17:06 DATE= 2015-09-06 D/A= 8C79 FREQ ERROR= -2.00E-09 FREQ CNT= 999,999,998 TIME= 13:18:48 DATE= 2015-09-06 D/A= 8C79 FREQ ERROR= -8.00E-09 FREQ CNT= 999,999,992 TIME= 13:18:48 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00199 FREQ ADJ CNT= 00186 AVG FREQUENCY ERROR= -2.00E-09 NEW D/A= 8C80 TIME= 13:20:30 DATE= 2015-09-06 D/A= 8C80 FREQ ERROR= +0.00E-09 FREQ CNT= 1,000,000,000 TIME= 13:22:12 DATE= 2015-09-06 D/A= 8C80 FREQ ERROR= -1.00E-08 FREQ CNT= 999,999,990 TIME= 13:23:54 DATE= 2015-09-06 D/A= 8C80 FREQ ERROR= +0.00E-09 FREQ CNT= 1,000,000,000 TIME= 13:23:54 DATE= 2015-09-06 AUTOMATIC D/A ADJUSTMENT MATCH CNT= 00200 FREQ ADJ CNT= 00187 AVG FREQUENCY ERROR= -3.00E-09 NEW D/A= 8C8B TIME= 13:25:36 DATE= 2015-09-06 D/A= 8C8B FREQ ERROR= -5.00E-09 FREQ CNT= 999,999,995 TIME= 13:27:18 DATE= 2015-09-06 D/A= 8C8B FREQ ERROR= +0.00E-09 FREQ CNT= 1,000,000,000 END OF LOG Powered by eBay Turbo Lister The free listing tool.
