Precision Test Systems manufacture a range of crystal and rubidium
frequency standards and can also supply cesium and hydrogen maser frequency
standards.

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

GPS10X Crystal
Based GPS Disciplined Frequency Standard
The GPS10X is a
very low cost GPS Disciplined OXCO frequency standard. Despite its low cost, the
GPS10X will delivery an accurate 10 MHz output (other frequencies optional
available). Phase noise is the best in its class. The GPS10X maintains an
output 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. |
