PSI releases a new generation of ultra-low phase noise oscillators
The SLOOP range of Sapphire Loaded Cavity Oscillators.
These oscillators represent a new level of affordability in ultra-low phase noise microwave oscillators, with typical phase noise performance surpassing that of the best quartz based signal sources, and exhibiting superbly clean and low far from carrier noise.
Based on PSI proprietary High Q Sapphire resonator technology integrated in a unique Loop Architecture these Sapphire LOOP oscillators drive like a sports car.*

Commencing on 1st September two new agents will start representing PSI in Europe.

Mr Bernd Rupp and his company Rupp Tronik will look after customers in Germany, Austria, Switzerland, Czech Republic, Hungary and Poland.
Mr. Dino Gusso and his company DMG Communications will look after customers in Italy and can also take initial inquiries from Spain and France.

We welcome our new European colleagues into the PSI family and wish them every success.

European customers please check the Contacts page for details.

Are You Measuring Phase Noise?

Now there is no reason you shouldn't measure phase noise and every reason to start. The ODIN-320A provides users with automatic and precise measurement of phase noise in oscillators and residual phase noise in components as well as amplitude noise measurement capabilities.









ODIN can measure in real time:
SSB Spectral Density of Phase fluctuations, L(f)
DSB Spectral Density of Phase fluctuations, S(f)
Spectral Density of Fractional frequency fluctuations, Sy(f)
Spectral Density of Amplitude noise fluctuations, M(f)
Phase Noise (PM) Cross Spectrum
Amplitude Noise (AM) Cross Spectrum
Two Oscillator phase noise measurements using phase detector method or phase locked loop (PLL) method
Phase Noise Measurements from 10MHz to 18GHz and above
Automatic conversion ratio measurements during phase noise measurements using plug-in receivers
Acceleration spectrum and Vibration sensitivity (Gamma) of oscillators under vibration
Power or Voltage Spectra of baseband signals from 1Hz to 6.4MHz
Time Domain and frequency domain measurements of baseband signals from 1Hz to 6.4MHz
Two channel Cross Spectral Density measurements
Flicker noise and Residual phase noise in devices (such as amplifiers and dividers)
Baseband frequency response (magnitude and phase) of two port networks from 1Hz to 6.4MHz
Two channel Coherence response from 1Hz to 6.4MHz
More than 30 Units of measurements such as dBm, dBc, dBc/Hz, dBpk/rHz, Vrms/rHz, dB, W/Hz, Vrms^2/Hz and many more.

Low Cost Low Phase Noise Oscillator

Poseidon's expertise in ultra-low phase noise sapphire-loaded cavity oscillators is now brought to bear in high performance, low phase noise DROs.

The excellent phase noise performance offered by the PSI range of DROs make them suitable for applications including:

• low-jitter communication systems
• low cost reference oscillators for phase noise measurements
• radar systems
• digital radio (QAM)

PSI releases a new Low Noise Divider Ensemble

When the LNDE is driven by one of PSI's low phase noise sapphire oscillators these outputs can provide the lowest phase noise signals reported at these frequencies

Our new address is:

On 27 March 2006 the Australian Department of Defence recognised Poseidon Scientific Instruments for its record of supply to the Australian Defence Organisation and the contribution it has made to the sustainment of capabilities of strategic importance to the Australian Defence Force.

Perth, Western Australia, is the planet's most remote city. It enjoys a clean environment, and beautiful beaches.
