The GPS is an economical and reliable Time and
Frequency instrument offering a wide range of standard
features in a compact, IU rack-mount chassis.
Precision time and frequency outputs, accurate to 40
nano- seconds to UTC/USNO and 1x10-12 respectively,
are provided in a variety of signal formats.
Two serial data ports, RS-422 and RS-232 are provided.
Time, date, position, GPS satellite health and signal
strength are reported.
Applications for the popular GPS8 include central time
and frequency systems, timing for power utility systems,
and frequency standards for a wide variety of
communications installations. The IRIG B output is
perfect for use in range timing installations, as inputs to
SER and SCADA systems and for driving remote time
displays. 1PPM and 1PPD or IRIG B DC shift may be
selected for output.
The serial time code output (IRIG B is standard) allows
time synchronization to be distributed to computers,
displays, and other equipment requiring precise time.
A variety of internal oscillators, including the standard
TCXO, provide price/performance trade-off possibilities
for the user. The GPS 8 can be specified to include an
oscillator that is appropriate for almost any application.
An advanced oscillator control algorithm precisely
disciplines the internal oscillator to the GPS input
ensuring superior holdover performance. In addition to
the standard TCXO, a variety of oven controlled
(OCXO) and Rubidium oscillators are optionally
available.
A precision 1PPS time mark output may be used for
synchronizing or calibrating other equipment.
Two square waves, 1.544, 2.048 or 19.6608 MHz, and an
8 kPPS frame rate enable the GPS 8 to be used as a
telecommunications primary reference clock (PRC).
Sine waves of 1, 5 or 10 MHz are also available. The sine
wave outputs are configured as two pairs of two of the
above frequencies. Signal level integrity monitoring is
provided for the sine wave outputs.
Status information is provided over the serial interface, by
a summary alarm, and by four front panel LED indicators.
The status reported by the summary alarm and the serial
interface includes loss of GPS signal, PLL unlock, loss of
output, and Rubidium oscillator unlock. (The rubidium
oscillator is an optional feature)
