ROHDE & SCHWARZ R&S FSPN phase noise analyzer and VCO tester provides both very high sensitivity and measurement speed for production and design engineers. Unit is suitable for demanding development and production phase noise and VCO analysis. Equipped with two low-phase noise synthesizers and a real-time cross-correlation engine for increased measurement sensitivity, just a few correlations are needed for production measurements. Increase the number of correlations to characterize the most sensitive commercially available synthesizers and oscillators in R&D. Product provides a frequency range from 1MHz to 8GHz/26.5GHz–163dBc (1Hz) at 1GHz carrier frequency and 10kHz offset. Unit delivers low‑noise internal dc sources for automatic VCO characterization.
