Key facts
The R&S®FSWP phase noise analyzer and VCO tester features very high sensitivity thanks to extremely low-noise internal sources and cross-correlation. It can measure phase noise and amplitude noise in mere seconds on highly stable sources such as those in radar applications. Additional options such as pulsed signal measurements, residual phase noise (including pulsed) characterization and integrated high‑end signal and spectrum analysis make the R&S®FSWP a unique test instrument.
Save time and multiply measurement throughput
The internal sources of the R&S®FSWP allow measurement of highly sensitive oscillators such as DROs and OCXOs with a minimum number of cross-correlations, saving considerable time. The addition of hardware accelerated signal processing in the R&S®FSWP phase noise analyzer enables real-time phase noise measurements. Short measurement time is key as it speeds up the process from development to manufacturing and increases production throughput.
Phase noise measurement
Phase measurement of a high-end OCXO using cross-correlation.
Highest sensitivity for phase and amplitude noise measurement
The FSWP internal local oscillator surpasses almost any signal generator available on the market when it comes to phase noise performance. Thanks to the analyzer's low‑noise internal sources, a few correlations are all that is needed to measure a high-quality oscillator. This allows for the fastest possible measurement times.
Phase noise and sensitivity
The results can be displayed in separate windows or together in one window.
High-end phase noise analyzer and signal and spectrum analyzer in a single box
Users can examine the spectrum and demodulate the signal to measure EVM or pulse characteristics in different measurement channels. Designers of automatic test systems save space and money since they do not have to purchase an additional spectrum analyzer or vector signal analyzer. The R&S®FSWP is a future-proof investment. It is based on the high-end R&S®FSW with its unique RF performance and high sensitivity.
The R&S®FSWP does it all
Vector signal analysis, pulsed signal analysis, measurement of higher harmonics, sensitive phase noise measurements, etc.
Easy analysis of pulsed signal sources
Measuring the phase noise of pulsed sources used in radar applications has never been easier. The R&S®FSWP captures the signal and calculates all pulse parameters instantaneously. It offers cross‑correlation for phase noise tests and automatically determines the trigger/gating parameters required for pulsed source measurements. Gating enables the R&S®FSWP to achieve a larger dynamic range for pulsed phase noise measurements compared to other methods.
Pulsed signal analysis
Automated measurement of pulse parameters in the time domain and phase noise in the frequency domain.
Residual PN measurements on pulsed and CW signals
For high‑end radar applications, knowing the additional phase noise added by individual components (e.g. amplifiers) to the signal path is crucial, since these influence pulse-to-pulse phase stability. The components have to be tested using pulsed signals under real-world conditions. The R&S®FSWP offers an internal signal source for measuring residual phase noise or pulse to pulse phase stability and it provides additional inputs for using other external sources as well.
Pulse-to-pulse phase stability
3D plot of pulse-to-pulse phase stability of several bursts.
Measure VCO parameters automatically
The R&S®FSWP features extremely low‑noise internal DC sources to supply and control voltage-controlled oscillators (VCO). The R&S®FSWP measures not only frequency and power of the fundamental but also the power of the VCO's higher harmonics relative to the tuning voltage. It also displays the phase noise at various offset frequencies relative to the tuning voltage.
VCO results
Frequency, output power, tuning slope and current consumption vs. tuning voltage.
Frequency and phase measurements in the time domain
The R&S®FSWP offers up to 8 GHz bandwidth for analyzing the frequency or phase characteristics versus time. Besides this wideband analysis, the R&S®FSWP offers narrowband analysis down to 40 MHz to examine the transient response of PLLs in detail.
Transient analysis
Persistence display of the frequency settling of a synthesizer.
Simultaneous measurement of amplitude noise and phase noise
The R&S®FSWP offers a new approach that allows concurrent measurement of amplitude and phase noise in parallel up to a frequency offset of 30 MHz. It displays both results simultaneously in one window or in separate windows.
Amplitude and phase noise
The grey area represents the improved sensitivity by cross-correlation, the yellow trace is the PN and the green one the AM noise.
Allan variance calculation from the close-in phase noise
To characterize the frequency stability of oscillators, the R&S®FSWP calculates the Allan variance from the phase noise and displays it for up to 1 million seconds (minimum offset: 1 μHz). Unlike the time domain methods, this makes it easy to suppress undesired side effects that appear as spurious emissions in the phase noise spectrum. Even short-term disturbances due to the phase noise of the instrument's internal sources can be easily suppressed with cross-correlation.
Allan variance and phase noise
Calculation of the Allan variance from 33 ns to 10 s based on the phase noise measurement for an offset range of 0.1 Hz to 30 MHz.
