Key facts
The R&S®FSPN phase noise analyzer and VCO tester is very sensitive with high measurement speeds for characterizing sources such as synthesizers, VCOs, OCXOs and DROs. It is ideal for demanding phase noise and VCO analysis in development and production . Equipped with 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. Increase the number of correlations to characterize the most sensitive commercially available synthesizers and oscillators in R&D.
Speed up the development of your device
Signal sources can be developed and optimized faster with an instrument that delivers results with short measurement times. The R&S®FSPN takes just a few seconds to display the phase noise trace of high-end sources such as OCXOs or DROs.

Real-time cross-correlation for improved phase noise sensitivity
The R&S®FSPN includes real-time cross-correlation to measure sources with very low phase noise. The sensitivity improvement depends on the number of cross correlations performed, as follows:
ΔL = 5 · log(n), where
Simultaneous phase noise and amplitude noise
The R&S®FSPN measures phase and amplitude noise in parallel and shows the current cross correlation sensitivity gain indicated by the gray area.
Thanks to its extremely low-noise internal DC sources, the R&S®FSPN can measure the phase noise of voltage-controlled oscillators (VCO) at various tuning and supply voltages. Quíck VCO characterization varying tuning voltage or the supply voltage is possible. The following parameters are delivered instantaneously:
VCO characterization
Frequency and phase measurements in time domain
The R&S®FSPN has up to 8 GHz bandwidth for detailed synthesizer characterization, including measurements of settling times after frequency hops, ramps, switching times etc. The R&S®FSPN has narrowband analysis down to 40 MHz for narrowband characterization when analyzing transient PLL responses in detail.
The display has a persistence mode for all traces, making it easy to estimate the intensity of the parameter scatter or the presence of any outliers.
Transient analysis, settling time measurement
SCPI recording makes it easy to move from manual operation to automated test sequencing. Just operate the instrument and export the automatically created scripts in different languages such as Matlab®, Python or C# to replicate the manual measurements.
