The R&S FSPN from Rohde & Schwarz is a Phase Noise Analyzer and VCO tester that operates from 1 MHz to 8/26.5 GHz. It is designed to provide both very high sensitivity and measurement speed for production and design engineers who need to characterize sources such as synthesizers, VCOs, OCXOs, and DROs.
This is the ideal instrument for demanding development and production phase noise and VCO analysis. It has two low-phase noise synthesizers and a real-time cross-correlation engine for increased measurement sensitivity, just a few correlations are needed to measure very high-quality oscillators, synthesizers, or VCOs in production. The number of correlations can be increased to characterize the most sensitive commercially available synthesizers and oscillators in R&D.
The analyzer also has a very low noise internal DC source that provides automatic VCO characterization for harmonics suppression measurement and enhanced tuning voltage capabilities. It can conduct transient response analysis up to 8 GHz for frequency and phase measurements in the time domain.
The R&S FSPN is available in a compact enclosure with control buttons, connectors, and a display that produces simultaneous amplitude & phase noise measurements in parallel.
