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, a wall mount power supply, a GPS Antenna with a 15 meter antenna cable, a rack mount kit and an operations manual.
Avoid the extra charges other company's tack onto their clocks. Arbiter's precision timing products, including the 1092A/B/C, include the GPS antenna and cable, a wall mount power supply, and an operations manual, all backed by a Limited Lifetime Warranty.
Model 1092A/B/C is available with three front panel configurations. See photos and Key Features tab for more information.
- Accuracy <500 ns
- Desktop version (optional rack mount kit is available)
- Unmodulated IRIG-B and 1 PPS included, modulated IRIG-B optional
- Multiple interface versions
Versions A/B/C offer various interface options (see photos):
- 1092A supports four LEDs for monitoring operating status.
- 1092B adds to the LEDs an LCD display and keypad, providing easy access to setup and system status information.
- 1092C includes both the operating status LEDs, the LCD display and keypad, and includes a large LED time display.
Receiver Characteristics
Timing Accuracy
| 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 |
| Typical | 10 meters, rms, 90% confidence |
Satellite Tracking
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.
Acquisition
- 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 1082s. This feature improves acquisition time by supplying constant power to the real-time clock and RAM in the GPS receiver module.
I/O Configuration
Output Connectors
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.
Event Inputs
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.
Four modes:
- Every 1 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 to 600 seconds, except in one-shot mode, where the output is Low prior to the specified time and High thereafter.
