Rohde & Schwarz FSWP Spec Sheet
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What makes the R&S FSWP50 suitable for millimeter wave phase noise testing?
The Rohde & Schwarz FSWP50 extends phase noise analysis capabilities to 50 GHz, covering frequencies from 1 MHz to 50 GHz when DC coupled (10 MHz to 50 GHz AC coupled). At 50 GHz carrier frequency with the R&S FSWP-B61 cross correlation option, it achieves phase noise sensitivity of -119 dBc/Hz at 1 kHz offset and -138 dBc/Hz at 10 kHz offset. This makes it ideal for characterizing millimeter wave oscillators, synthesizers, and frequency converters used in 5G, satellite communications, and radar systems.
How does the FSWP50 phase noise sensitivity compare across different carrier frequencies?
The FSWP50 delivers exceptional phase noise sensitivity that scales with carrier frequency. With the R&S FSWP-B61 option at 100 MHz carrier, it measures -166 dBc/Hz at 1 kHz offset and -170 dBc/Hz at 10 kHz offset. At 10 GHz, sensitivity is -133 dBc/Hz at 1 kHz and -152 dBc/Hz at 10 kHz offset. At the maximum 50 GHz carrier, it maintains -119 dBc/Hz at 1 kHz and -138 dBc/Hz at 10 kHz offset. These specifications enable accurate characterization across the entire microwave and millimeter wave spectrum.
What offset frequency range does the FSWP50 support for phase noise measurements?
The R&S FSWP50 provides comprehensive offset frequency coverage from 10 millihertz to 30 percent of the carrier frequency for input signals up to 3.33 GHz. For higher carrier frequencies above 3.33 GHz, the offset range extends from 10 mHz to 1 GHz, allowing detailed characterization of both close-in and far-out phase noise. This wide offset range is essential for evaluating oscillator performance across multiple decades of offset frequencies, from ultra-low frequency flicker noise to wideband noise floor measurements.
Can the FSWP50 measure transient frequency behavior of oscillators?
Yes, the FSWP50 includes transient analysis capabilities for characterizing frequency settling behavior and frequency jumps in oscillators and synthesizers. It offers narrow mode frequency resolution for detailed analysis from 256 MHz to 8 GHz, as well as wide mode operation across the same range for faster capture of transient events. The instrument can also perform Allan deviation and Allan variance measurements to quantify oscillator stability over various time intervals, critical for evaluating frequency references in precision timing applications.
What spurious performance does the FSWP50 provide in phase noise measurements?
The R&S FSWP50 exhibits excellent spurious suppression with spurious level specifications that depend on carrier frequency and offset. For carriers below 1 GHz, spurious signals from 10 Hz to 1 kHz offset are less than -90 dBc, and less than -100 dBc for offsets above 1 kHz. For carriers at or above 1 GHz, the spurious specification adjusts by 20 log(fin/GHz), ensuring predictable performance across the full frequency range. This low spurious content prevents false peaks from obscuring real phase noise characteristics.
Does the FSWP50 support external mixer operation for higher frequencies?
Yes, with the optional R&S FSWP-B21 LO/IF connections for external mixers, the FSWP50 can be extended to even higher frequencies beyond its native 50 GHz range. The option supports both single external mixer configurations and dual external mixer cross correlation mode when combined with the R&S FSWP-B60 or R&S FSWP-B61 cross correlation options. This allows phase noise testing of sources operating at V-band, W-band, and higher millimeter wave frequencies while maintaining the FSWP50's excellent measurement sensitivity and accuracy.
What baseband noise measurement capabilities does the FSWP50 offer?
The FSWP50 provides dedicated baseband noise measurement functionality covering 10 mHz to 30 MHz when DC coupled or 10 MHz to 30 MHz when AC coupled. This mode allows direct characterization of baseband signals, VCOs without upconversion, and measurement of noise on DC control voltages. The instrument can measure baseband noise level characteristics and perform VCO characterization including frequency, RF power, and DC supply current measurements, making it valuable for oscillator design verification and troubleshooting.
What reference frequency stability does the FSWP50 provide?
The FSWP50 features a high-stability internal reference oscillator with standard aging of ±1 x 10^-7 per year. With the optional R&S FSWP-B4 OCXO precision frequency reference, aging improves dramatically to ±5 x 10^-8 in the first year and ±3 x 10^-8 per year thereafter. The OCXO option also provides exceptional temperature stability of ±1 x 10^-9 over the 0 degrees C to +50 degrees C operating range and initial calibration accuracy of ±5 x 10^-9, ensuring the instrument's own reference does not limit phase noise measurement accuracy.
