RF Test Measurement System

The RF Test Measurement System (TMS) makes use of microwave photonic methods for automated measurements of ultra-low phase noise oscillators.

It is fast, fully automated and provides the spectral density of the phase noise of an RF or microwave signal source at any operating frequency in the specified bands.

This homodyne-based system is distinct in wide frequency band measurement without needing another low noise reference source or down-converter.

Defining Features

• Ultra-Low Phase/Frequency Noise Measurement Capability

• Fast Real-Time Measurement 

• Fully Automated

• Cross-Correlation Homodyne Capability

No Low Noise Reference Source Required

User Friendly Interface

• Simple PC-based Operation

6U x 19'' Rack System

• Customizable Configurations, Upgrades and Options
