Model 1092A/B/C GPS Satellite-Controlled Clock (500 ns)
Need value and performance in a desktop model? This precision time clock model brings economy and flexibility to environments that don’t need or use a rack mount system.
With two terminal strip outputs providing unmodulated IRIG-B and 1 PPS signals, the 1092A/B/C is capable of driving multiple loads in parallel.
Like other Arbiter clock models, various options are available to extend the functionality of the base model. Features supported include a second RS-232 port, an Out-of-Lock Relay Form C SPDT, an IRIG-B Modulated Output, and the reconfiguring of 1 PPS and IRIG-B Output to Programmable Pulse. The 1PPS Output may also be reconfigured to be an Event Input.
Adding value, each Model 1092A/B/C includes a Limited Lifetime Warranty to the original owner/purchaser, a wall mount power supply, a GPS Antenna with a 15 meter antenna cable, and an operations manual. Avoid the extra charges other company’s tack onto their clocks!
Model 1092A/B/C is available with three front panel configurations. See photos and Key Features tab for more information.
|Accuracy Note||Specifications apply at the 1 PPS output, in the presence of Selective Availability (SA), as of date of publication.|
|Accuracy UTC/USNO||± 500 ns peak|
Twelve (12) channel, C/A code (1575.42 MHz). Receiver simultaneously tracks up to twelve satellites. Results from all tracked satellites are averaged in Position-Hold Mode or, with Position-Hold Mode off, using least-squares estimation.
- 150 seconds typical, cold start
- 15 minutes, 90 % confidence, cold start
- 40 seconds, with almanac less than 1 month old
- 15 seconds, with ephemeris less than 4 hours old
- The GPS Data Backup Battery is included in all Model 1092s. This feature improves acquisition time by supplying constant power to the real-time clock and RAM in the GPS receiver module.
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.
Open-drain FET drivers (400 V, 220 mA, 1 W power dissipation) can also be fitted; contact factory.
One event timer channel with 1 µs resolution is standard. This function may be driven by the start bit of a received character on the serial port, or (by internal connection) an external 5 V CMOS/TTL signal at one of the terminal strip connectors.
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.
- Every 1 second to 60,000 seconds, starts top of the minute
- Hourly at a specified offset
- Daily at a specified time of day
- One shot at a specified time of year
Pulse duration is programmable from 0.01 seconds to 600 seconds, except in one-shot mode, where the output is Low prior to the specified time and High thereafter.
