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.*

- ODIN 320 Phase Noise Analyser
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 Phase Noise DRO
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)
- Low Noise Divider Ensemble (LNDE)
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

- PSI acknowledged by the Australian Department of Defence
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.
- PSI... why it lives and works in Western Australia
Perth, Western Australia, is the planet's most remote city. It enjoys a clean environment, and beautiful beaches.

- ODIN Supports ATE Integration
Wednesday, November 25, 2009
An important aspect of any phase noise instrument is the integration with exisiting production test equipment. The latest release of the ODIN-320A firmware (v1.100) supports Automated Test Equipment (ATE) control for rapid automated measurements in a production environment or remote instrument operation for easy configuration of common measurements.

- OD-103 Delay Line
Wednesday, November 25, 2009
The OD-103 delay line works in conjunction with the ODIN-320 analyser to automate residual noise measurements on two-port devices. Working together, the OD-103 and the ODIN-320 automatically measure all of the necessary parameters for phase noise measurement, such as conversion ratio, and then the OD-103 delay line automatically adjusts the phase length between its RF In and RF Out connectors to achieve phase quadrature at the ODIN receiver for precise phase noise measurements. Thereby saving operator time.
