Model 1 084A/B/C
GPS Satellite-Controlled Clock
The Arbiter Systems®, Inc. Model 1 084A/B/C GPS
Satellite-Controlled Clock provides the most-needed
GPS system clock features in an economical package.
Three versions allow you to match your requirements.
The Model 1 084A has four LEDs to monitor operating
status. The Model 1 084B adds an LCD setup/status
display and keyboard. The Model 1 084C adds a large
(20 mm or 0.8 in) LED time display.
In all versions, one BNC output provides modulated
IRIG-B while another BNC output is jumper configurable
for IRIG-B unmodulated or Programmable Pulse. Both
outputs have substantial drive capability and can easily
drive multiple loads wired in parallel. A third output is
jumper configurable for either one pulse-per-second,
IRIG-B unmodulated, or IRIG-B modified Manchester
(IEEE Standard 1 344 high-precision time code). This
third output may also be wired (by a simple modification)
to any of the other digital signals generated inside the
Model 1 084A/B/C. These signals include rates of 1 PPH,
1 PPM, 1 0 PPS, 1 00 PPS, 1 kPPS, 1 0 kPPS, 1 00 kPPS,
1 MPPS, 5 MPPS, and 1 0 MPPS; IRIG-E, IRIG-H, and
IRIG-D; Programmable Pulse, or Locked to satellite.
Programmable Pulse generates an output pulse every
1 second to 60000 seconds, daily at a specified time,
or at a specified time of year; pulse duration is 0.01
seconds to 600 seconds. An optional fiber-optic output
generates 1 PPS or IRIG-B in either unmodulated or
modified Manchester format. Also, an event timer input
measures time of occurrence of an applied pulse to
1 00 ns resolution. Up to 500 events may be stored.
The Model 1 084A/B/C includes two Form C (SPDT)
fail-safe relays, compatible with 1 29 Vdc digital fault
recorder inputs. The first provides a LOCKED indication,
and the second can be selected to the FAULT, 1 PPH,
or Programmable Pulse functions.
Twelve receiver channels are standard for best
performance, especially in difficult locations. The internal
backup oscillator is a digitally-compensated crystal
oscillator (DCXO) accurate to 1 x 1 0
-7
over temperature.
Power options include 85 Vac to 264 Vac or 1 1 0 Vdc
to 370 Vdc with an IEC-320 detachable cordset, 85 Vac
to 250 Vac or 1 1 0 Vdc to 350 Vdc terminal strip inlet with
surge withstand, or 1 0 Vdc to 60 Vdc terminal strip inlet
with surge withstand. The terminal-strip versions have
a surge-withstand network designed to meet ANSI/IEEE
C37.90-1 and IEC801 -4 specifications. All power
configurations may be retrofitted in the field.

Receiver Ch a racteristics
Ti ing Accuracy
Specifications apply at the 1 PPS output, in the presence
of Selective Availability (SA), as of date of publication.
UTC/USNO ± 1 00 ns rms, 1 PPS output
Typical < 40 ns rms, in Position-Hold Mode
Internal Oscillator
Standard DCXO, 1 x 1 0-7, unlocked
Allan variance (locked and in Position-Hold Mode)
1 second 5 x 1 0-1 0 (2 x 1 0-1 0, typical)
1 day 5 x 1 0-1 3
Synchronization
CMOS output signals are synchronized to the 1 PPS
output, ± 50 ns maximum.
IRIG-B modulated, ± 1 µs maximum
The leading edge of the start bit of a received RS-232
data message may be selected to trigger the Event A
input, providing synchronization with 1 00 ns resolution.
Position Accuracy
1 0 meters, rms, 90 % confidence
Satellite Tracking
Twelve (1 2) channel, GPS-L1 , C/A code (1 575.42 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
1 50 seconds typical, cold start
1 5 minutes, 90 % confidence, cold start
40 seconds, typical, with almanac < 1 month old
1 5 seconds, typical, with ephemeris < 4 hours old
The GPS Data Backup Battery is included in all Model
1 084s. This feature improves acquisition time by supplying
constant power to the real-time clock and RAM in the
GPS receiver module.
I/O Configuration
Connectors
Three standard; one IRIG-B modulated connector and
two user-configurable connectors:
1 . IRIG-B modulated, bus driver, 4 Vpp, 20 ohms source
impedance, drives a 50-ohm load at 3 Vpp
2. IRIG-B unmodulated or Programmable Pulse; jumper-
selectable
3. 1 PPS, IRIG-B unmodulated or IRIG-B modified
Manchester; jumper-selectable
umper-selectable outputs are 5 V CMOS bus drivers
with 1 0 ohms source impedance and ± 75 mA drive capability.
Relay Contacts
Two (2) sets, Form C (SPDT) fail-safe, 0.3 A at 1 30 Vdc;
one is Locked function; the second one is jumper-
selectable and may be Fault, 1 PPH, or Programmable Pulse
Progra able Pulse Output
Four modes:
• Every 1 s to 60,000 s, 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.
Event A Input
One input is available as an alternate function, with a
simple hardware modification to the 1 PPS configurable
output. The input may be configured to accept an external
1 PPS signal and measure the deviation from 1 PPS/GPS
with 1 00 ns resolution. Each input may also be configured
to record up to 500 sequential events with 1 00 ns
resolution, provided that the events are separated by
1 1 ms. Event data is stored in battery-backed RAM.
