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 Protocol) 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.

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

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.

Firmware Version and Related Information

EPROM update (1092/1093_Firmware)

Version	Version Notes
11Aug2011	Update to the time quality functionality so it no longer displays locked, maximum accuracy immediately after reacquiring satellites.
26May2011	Fix IP address display to use periods (.) instead of colons (:).
12May2011	Add Option 34/35 support. Add "IP" serial command to return Option 34/35 IP addresses. Add display of Option 34/35 MAC addresses Add bit to indicate if unit has ever been locked to GPS. Update NTP status screens.
18Oct2010	Update serial "RD" output to be consistent across all clocks (reference BZ 489). Fix Option 28 XI configuration command (reference BZ 490). Leap second pending always 0 for Motorola 8-channel receiver (reference BZ 632). Fix 1093 Optional RS232 port periodically responded with "garbage" data (reference BZ 635).
02Nov2009	Fix power-up set defaults: Incorrectly had to wait until "SETUP" key released. Possible survey fix: "Zero" positions will now be ignored when doing survey calculation. Complete "Position Hold ID" (user or survey position flag) Block user from changing user position or position hold setting while survey active. Broadcast format time moved from the 20ms mark to 100ms mark. It was moved to give Option-28 enough time to format broadcast messages. (Opt-28 broadcast data was being copied while it was still being update causing some "0x00" characters to randomly appear in the message) DEBUG CODE: Output lat-long dif when debug_mode broadcast set to mode 2.

EPROM Update (Option28_Firmware)

Version	Version Notes
13Jul2006	Improved compatibility during transfer of correction values to option 28.
