Distribution Amplifiers

Precision Test Systems manufacture a complete range of distribution amplifiers. 

Our distribution amplifiers are used to distribute a signal from a reference oscillator.  The reference oscillator is usually a crystal, rubidium, cesium or hydrogen maser frequency standard

The frequency range is typically 5 MHz or 10 MHz although we make amplifiers for any frequency.  Other standard frequencies are 1 MHz, 2.048 MHz, 13 MHz, 15 MHz, 75 MHz, 80 MHz, 100 MHz, 1575.42 MHz etc.

The distribution amplifier can have from 5 to 30 outputs.  Amplifiers can be cascaded to give well over 1000 outputs from one single source.

Ultra low phase noise
Our model DA1-100-10 is an ultra low phase noise distribution amplifier.  Phase noise is typically < -130 dBc/Hz at a 1 Hz offset with noise floors to < -170 dBc.

High channel and reverse isolation
Our models of amplifiers have high isolation to protect the reference oscillator and to minimise crosstalk and noise.  For example our DA1-100-10 has 90 dB channel to channel isolation and > 130 dB of reverse isolation at 10 MHz.

A model for every budget
We have many models of distribution amplifiers that fit every budget.  Our Website has a comparison page that details most of our amplifiers.

Bespoke Models
If you need a feature that isn't already on our Website, then send an email and we will quote to make it for you.  We don't charge excessive design charges as this is always a good way to bring out new features to all our models of test equipment.

Frequency Standard

Precision Test Systems manufactures and supplies a wide range of frequency standards.  Models include crystal, rubidium, cesium and hydrogen masers.  Oscillators can either be free running or locked to an external signal or have built-in GPS receivers.

A comparison page lists all our standard models.

Low Phase Noise
We manufacture some of the worlds lowest phase noise oscillators.  Our 10 MHz CFS10B can have close in phase noise of -112 dBc/Hz at a 1 Hz offset with a -173 dBc/Hz noise floor.

Many Options
We have many options for our frequency standards including redundancy, many outputs, sine, square or pulse outputs, different frequencies, time code outputs etc.

The time code outputs include IRIG-B, BCD, ASCII, NTP etc.
