Arbiter Systems 1084A Manual

Model 1 084A/B/C
GPS Satellite-Controlled Clock
The Arbiter Systems
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
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.
