Rohde & Schwarz Unveils Phase Noise Analyzer & VCO Tester
Rohde & Schwarz has launched the new R&S FSPN phase noise analyzer and VCO tester with superb sensitivity, accuracy and reliability for high-speed, real-time phase noise measurements using sources that require high stability in demanding applications.
As a pure phase noise analyzer and VCO tester, the R&S FSPN provides an unrivaled combination of performance and ease of use.
Rohde & Schwarz designed the new R&S FSPN phase noise analyzer and VCO tester for production and design engineers who characterize sources such as synthesizers, VCOs, OCXOs, and DROs.
Providing very high sensitivity and measurement speed, the R&S FSPN is ideal for demanding phase noise and VCO analysis in development and production.
The R&S FSPN from Rohde & Schwarz comes in two models: one covers the frequency range from 1 MHz to 8 GHz and the other from1 MHz to 26.5 GHz, addressing radar and satellite applications in the C band, X band, Ku band, and the complete K band.
Catering to the unique measurement challenges in these fields, the R&S FSPN expands the Rohde & Schwarz phase noise product portfolio which already contains the successful, market-leading ultra-high-performance R&S FSWP phase noise, spectrum and signal analyzer.
The R&S FSPN shares tried-and-tested R&S FSWP features such as low noise internal local oscillators coupled with real-time cross-correlation engines for increased measurement sensitivity.
To investigate oscillator long-term frequency stability, the R&S FSPN calculates the Allan variance in the time domain at fixed intervals and uses phase noise measurements to apply cross-correlations and suppress spurs.
The R&S FSPN is also equipped with three ultra-low-noise DC sources to supply and sweep VCOs. The built-in VCO characterization measurement mode analyzes VCO characteristics such as frequency, sensitivity, RF power or current draw versus tuning voltage.
For a more in-depth view of the device under test, the spot-noise versus tune measurement mode combines a sweep with ultra-low-noise DC sources plus fast and accurate phase noise measurements. VCO harmonics can also be measured versus tuning voltage without an additional spectrum analyzer.
Since Rohde & Schwarz designed the R&S FSPN as a pure phase noise analyzer, all relevant measurement modes and enhancements come standard. Users only need to choose the frequency range to order.
