Model 1093A/B/C GPS Satellite-Controlled Clock

Also available, the Model 1092A/B/C GPS Satellite-Controlled Clock provides the same performance and functionality as the Model 1093A/B/C, but has a small, tabletop chassis and an external (wall-mount) power supply.

Standard power options include 85 to 264 Vac/110 to 350 Vdc, with either IEC-320 or terminal strip inlet, and 10 to 60 Vdc with terminal strip inlet. The terminal-strip versions have a surge-withstand network designed to meet ANSI/IEEE C37.90-1 and IEC801-4 specifications. Power configurations may be retrofitted in the field.

An event capture input is standard, and may be wired to one of the output connectors or used for synchronizing data collection on an external computer via the serial port. This input has 1 ?s resolution. A programmable-pulse output may be used to generate an output pulse at the IRIG-B unmodulated or the 1 PPS outputs in addition to the AUX OUT on the RS-232 Port.

Other available option include Four Additional Configurable Outputs (1093opt03); High Drive IRIG-B Outputs (1093opt27); Power System Time, Frequency, and Phase Monitor (1093opt28); one Form C (SPDT) fail-safe, LOCKED relay (1093opt93) that is compatible with 129 Vdc digital fault recorder inputs; plus many more.

The GPS Data Backup Battery is now included in the Model 1093A/B/C. This feature improves acquisition time to as little as 15 seconds after a brief power loss by supplying constant power to the real-time clock and RAM in the GPS receiver module.

Two pluggable terminal strip outputs provide unmodulated IRIG-B and 1 PPS. A modulated IRIG-B output (1093opt92) is available on a third pluggable terminal strip output. 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 Arbiter Systems^?, Inc. Model 1093A/B/C GPS Satellite-Controlled Clock is a GPS timing source for applications which do not require the ultimate, 100 ns accuracy of our higher-performance models. The Model 1093A/B/C has 500ns worst-case accuracy, to meet the requirements of a broad range of applications. The Model 1093A has two LEDs to monitor operating status. The Model 1093B adds an LCD setup/status display and a keyboard. The Model 1093C also includes a large (20 mm or 0.8 in.) LED time display. In all versions, twelve receiver channels provide optimum performance.
