What frequency range does the R&S FSWP26 phase noise analyzer cover?

The Rohde & Schwarz FSWP26 phase noise analyzer supports RF input frequencies from 1 MHz to 26.5 GHz when DC coupled, or 10 MHz to 26.5 GHz when AC coupled for phase noise and AM noise measurements. For baseband noise measurements, the instrument covers 10 mHz to 30 MHz DC coupled or 10 MHz to 30 MHz AC coupled. This broad frequency coverage enables comprehensive phase noise characterization of oscillators, synthesizers, and other frequency sources across microwave bands.

What phase noise sensitivity does the FSWP26 achieve with cross correlation?

With the R&S FSWP-B61 cross correlation (low phase noise) option, the FSWP26 delivers exceptional phase noise sensitivity. At a 26 GHz carrier frequency, it achieves -125 dBc/Hz at 1 kHz offset and -144 dBc/Hz at 10 kHz offset (correlation factor = 1, signal level of 10 dBm or greater). The cross correlation technique can improve sensitivity by 5 dB with 10 correlations, 10 dB with 100 correlations, 15 dB with 1000 correlations, and up to 20 dB with 10,000 correlations for offset frequencies of 1 Hz and above.

How does the FSWP26 measure phase noise at very close-in offsets?

The FSWP26 excels at close-in phase noise measurements with offset frequency range starting from 1 microhertz up to the maximum input frequency minus the carrier frequency for lower carriers, or up to 1 GHz offset for carriers above the maximum frequency minus 1 GHz. At 26 GHz carrier with the R&S FSWP-B61 option, the instrument measures -18 dBc/Hz at 0.1 Hz offset and -47 dBc/Hz at 1 Hz offset with internal reference loop bandwidth set to 30 Hz, enabling characterization of ultra-low noise oscillators and atomic frequency standards.

What is the measurement uncertainty of the FSWP26 for phase noise testing?

The R&S FSWP26 provides excellent measurement accuracy with phase noise measurement uncertainty less than 1.5 dB for offset frequencies from 10 mHz to 1 MHz when the device under test phase noise is at least 15 dB above the FSWP sensitivity. For offsets from 1 MHz to 30 MHz, the uncertainty is less than 2 dB, and for offsets above 30 MHz it is less than 3 dB. Level measurement uncertainty is less than 2 dB for signal frequencies from 8 GHz to 18 GHz and less than 3 dB above 18 GHz at signal levels from -20 dBm to +15 dBm.

Can the FSWP26 also function as a spectrum analyzer?

Yes, with the optional R&S FSWP-B1 spectrum analyzer option, the FSWP26 transforms into a full-featured spectrum analyzer covering DC coupled operation from 2 Hz (with option) or 10 MHz to 26.5 GHz. In spectrum analyzer mode, it offers resolution bandwidths from 1 Hz to 10 MHz, displayed average noise levels of -149 dBm (typical -154 dBm) from 1 MHz to 1 GHz with preamplifier off, and sweep times from 3 microseconds to 16000 seconds, making it a versatile dual-purpose instrument.

What signal level range can the FSWP26 measure for phase noise analysis?

The FSWP26 accommodates a wide signal level range with two level settings for phase noise measurements. In high level setting mode, it accepts signals from -20 dBm to +30 dBm, while the low level setting extends the lower range to -40 dBm to +30 dBm. This flexibility allows characterization of both low-power sources and high-power oscillators without external attenuators or amplifiers. The instrument automatically optimizes measurement parameters based on the selected level setting to ensure optimal phase noise sensitivity.

How does the FSWP26 suppress AM noise in phase noise measurements?

The R&S FSWP26 incorporates excellent AM suppression capabilities to ensure accurate phase noise measurements on sources with amplitude modulation. It provides 40 dB nominal AM suppression for offset frequencies from 10 mHz to 1 MHz. For offsets from 1 MHz to 30 MHz in high level setting, and 1 MHz to 10 MHz in low level setting, AM suppression is 30 dB nominal. This high AM rejection prevents amplitude fluctuations from corrupting phase noise measurements, particularly important when testing free-running oscillators or sources with significant AM content.

What reference frequency options does the FSWP26 offer?

The FSWP26 features a high-stability internal reference with achievable initial calibration accuracy of ±1 x 10^-8 standard or ±5 x 10^-9 with the R&S FSWP-B4 OCXO precision frequency reference option. Standard aging is ±1 x 10^-7 per year, improving to ±3 x 10^-8 per year after the first year with the OCXO option. Temperature drift with the OCXO option is exceptionally low at ±1 x 10^-9 over 0 degrees C to +50 degrees C. The frequency resolution of 0.01 Hz enables precise frequency domain analysis for demanding metrology applications.
