The GPS10RBN is our top selling
GPS Disciplined, Rubidium Frequency Standard. The
GPS10RBN combines the stability of a rubidium oscillator
with the accuracy of the GPS satellite system.
The GPS10RBN is being used in over 53 countries by many
space observation centers, telecommunication companies,
GSM cell phone networks providers, major universities as
well as large manufacturing centers and the military.
What makes the GPS10RBN so special when compared to its
competitors is listed below:
-
Competitive Pricing. -
Low
phase noise. Up to 30 dB better than some
competitors. -
High
frequency accuracy. At least ten times more
accurate than OXCO based systems. -
Multiple outputs locked to main reference at any
frequency from 0 to 40 GHz. -
Low Microphonics. -
High reliability thus a three year warranty -
Many options meaning it can be adapted to suit
your individual requirements.
Rubidium Based Unit
The GPS10RBN incorporates an atomic
rubidium oscillator as the main frequency reference, but
costs the same as some competitive units that use less
accurate crystal oscillators. The rubidium used in the
GPS10RBN is 30 times more stable than any OXCO
available. Therefore the GPS10RBN achieves a frequency
stability of typically 7 x 10E-13 in 1000 sec.
Frequency Standards that use a
crystal oscillator as the main reference can only
achieve this stability when measurements are averaged
over one week or one month.
Accurate Timing Outputs
There are two 1 pps (pulse per second)
outputs that are derived from the GPS receiver or the
rubidium oscillator. The 1pps signal from the GPS
receiver is aligned to UTC with less than 20 ns error.
The 1 pps from the rubidium is also aligned to UTC but
has the advantage of less than 300 ps jitter.
Very Low Phase Noise
The GPS10RBN is one of the lowest phase
noise frequency standards available, at any price! Phase
noise is often overlooked, but is one of the most
important specifications of a frequency standard.
It's essential for a reference to a
frequency distribution system to have better phase noise
than equipment is supplies. The standard GPS10RBN
typically achieves -134 dBc/Hz at a 10 Hz offset and
even lower phase noise is available via a special
option.
Multiple Outputs
The GPS10RBN has built in ultra low
phase noise distribution amplifiers that provide high
channel to channel and reverse isolation. Up to 20
signal outputs can be supplied inside the 19" 2U case.
These outputs can be at any frequency, e.g. 5 MHz, 10
MHz, 10.23 MHz, 13 MHz, 100 MHz, 1 GHz etc. All
outputs are phase locked to the main rubidium reference.
Many Options
There are nearly 100 options for the
GPS10RBN. If there isn't an option that meets your
requirements, we will make one for you. That's how
we've got so many options already.
Some of the options include:
Squarewave outputs or Sinewave outputs
DDS Signal generator. Provides
a 0 - 80 MHz output in 1 µHz steps.
Remote control interfaces, either
RS232, USB or Ethernet
Windows software and software for
remote operation via the internet.
Alarm outputs, either change over
relay or alarm via GSM - SMS or text
Redundancy. Two units operate as a
pair for high reliability systems.
Time Code outputs, including IRIG-B,
BCD, SMPTE, NTP.
External DC input and/or battery
backup
Lightening Protection for the GPS
antenna
Fiber optic links for the antenna
cable and main signal outputs.
External locking, either 1 pps, 5
MHz, 10 MHz or any other frequency.
