Model 1093A/B/C delivers better than 500 ns accuracy and includes the most highly sought after features in a precision time clock as standard.
With two terminal strip outputs providing unmodulated IRIG-B and 1 PPS signals, the 1093 is capable of driving multiple loads in parallel. An optional modulated IRIG-B port is available adding greater flexibility.
Like other Arbiter clock models, various options are available to add features such as NTP (Network Time Proocol) support, four additional configurable outputs, high drive IRIG-B outputs, power system time, frequency, and Phase Monitor functions, one Form C (SPDT) fail-safe, LOCKED relay that is compatible with 129 Vdc digital fault recorder inputs; plus many more.
Versions A/B/C offer various interface options (see photos and Key Features tab). Each product includes the GPS antenna and cable, an appropriate power inlet and power cord, a rack mount kit and an operations manual, all backed by a Limited Lifetime Warranty.
Model 1093A/B/C is available with three front panel configurations. See photos and Key Features tab for more information.
- Accuracy <500 ns typical
- Unmodulated IRIG-B and 1 PPS included, modulated IRIG-B optional
- Options include an internal NTP server, High Drive IRIG-B outputs, One Form C (SPDT) fail-safe locked relay, Power System Time,
- Frequency and Phase Monitor
Versions A/B/C offer various interface options (see photos):
- 1093A supports four LEDs for monitoring operating status.
- 1093B adds to the LEDs an LCD display and keypad, providing easy access to setup and system status information.
- 1093C 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 | ±500ns peak |
Position Accuracy
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 now included in the Model 1093s. 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.
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 tech support.
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.
