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 1 µs 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.
Two pluggable
terminal strip outputs provide un-modulated 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 GPS Data Backup
Battery is now included in the Model 1092A/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.
Other available
options 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.
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 µs
resolution. A programmable-pulse output may be used to
generate an output pulse at the IRIG-B un-modulated or the 1
PPS outputs in addition to the AUX OUT on the RS-232 Port.
Standard power
options include 85 to 264 Vac/110 to 275 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.
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. |
