Precision Test
Systems manufacture a range of crystal and rubidium
frequency standards and can also supply cesium and
hydrogen maser frequency standards.
CLICK HERE FOR OUR FREQUENCY
STANDARD COMPARISON CHART
Models include Cesium,
Hydrogen Masers, GPS Disciplined, Rubidium and OXCO.
Unit are either complete stand alone models or simple
modules such as our
Rubidium range.
See below for more
details.
We also manufacture redundant
frequency / timing systems for ultimate reliability
(Click on title for the brochure) |
|
CFS10A and
CFS10B
These units are
based on oven controlled crystal oscillators. The
CFS10A is a low cost unit and the CFS10B features an
ultra low phase noise. The ultra low phase noise
option has phase noise of -112 dBc/Hz at 1 Hz with a
-171 dBc/Hz noise floor (single output unit). Optional
for up to ten isolated outputs are available as well.

DA101010-03 Crystal Frequency Standard
The DA101010-03 is a crystal standard with a high
stability OXCO as the frequency reference. There are
also ten sinewave and two squarewave outputs. The
internal frequency reference has a daily aging rate of 2
x 10-10 per day. Options such as an Alarm Relay and
Redundancy are available. The DA101010-03 can also
accept an external input. The DA101010-03 operates at 10
MHz, but other frequencies from 1 to 50 MHz are
available. |

GPS10R / RB / RBN Rubidium Based
GPS Disciplined Frequency Standards
These GPS Disciplined Rubidium
Frequency Standards are our most accurate
frequency standards having long term accuracy of parts
in 10E-13. Various time code outputs can be optional
added to these frequency standards, including IRIG-B or
E and BCD Time Code Output.
The GPS10R is a bench
mount model while the GPS10RB and GPS10RBN are 19" rack
mount models. The GPS10RBN has improved phase
noise, channel isolation and phase matching of the
outputs |
|
GPS10e and
GPS10X Crystal Based GPS Disciplined
Frequency Standard
The GPS10e and GPS10X are low cost GPS Disciplined OXCO
frequency standard. Despite their low cost, these units
will delivery an accurate 10 MHz output (other
frequencies optional available). Phase noise is the best
in its class. Accuracy is maintained with an accuracy of typically < 1E-12 (averaged
over one week). Many options are available including ten
isolated outputs. |
|
RFS10C Rubidium Frequency Standard
The RFS10C is a 10 MHz rubidium frequency
reference which offers excellent performance for
virtually any frequency or timing application. It is
ideal for instrumentation and communication systems
which require a precise frequency reference. The RFS10C
is supplied in a 19” rack mount case and is powered from
a 100-240 VAC power supply. |
RFS10E
Rubidium Frequency Standard
The RFS10E is a 1U low profile rubidium
frequency standard.
The RFS10E has a 10 MHz output and can also have an
optional distribution amplifier giving up to ten
outputs. |
|
RFS10F
and
RFS10G
Rubidium Frequency Standards
The RFS10F and RFS10G are rubidium
frequency standards with ultra low phase noise.
The RFS10F has a 10 MHz output and can also have an
optional second frequency output such as 10.23 MHz (other frequencies available).
The RFS10G is a ultra low phase noise 10 MHz rubidium
oscillator. Phase noise is -110 dBc/Hz at 1 Hz and
drift is 5 x 10E-11 / month. Both units are housed
in a 2U 19" rack mount case and are powered from 100 -
240 VAC supplies. |

Rubidium Oscillator Modules
Rubidium oscillators can be used as
frequency references in OEM applications. Low cost
models are available as well as many options. |
|
SG1640 Crystal Based GPS Disciplined
Frequency Standard
The SG1640 is a 10 µHz to 1640 MHz synthesizer with a
GPS disciplined oven controlled crystal oscillator. This
product is a low cost alternative to our rubidium based
units and offers very good performance at low cost. |
|
Custom Made Units
Precision Test Systems will gladly design
any option specially needed for a customer. Design costs
are not excessive and design time is very quick.
Most of our products started out as "customer specials". |
|
Options Available
Many options are available for our range
of frequency standards. Options include battery
backup, up to 1000 outputs, different frequencies,
various timing outputs, redundancy, special equipment
cases etc. Contact us for your special design
requirements. |
