Rohde & Schwarz FSW Brochure
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What is the frequency range of the Rohde & Schwarz FSW50 signal and spectrum analyzer?
The R&S FSW50 covers 2 Hz to 50 GHz with DC coupling, and 10 MHz to 50 GHz with AC coupling. The instrument features a YIG preselector for frequencies from 8 GHz upward, ensuring image-free spectrum analysis and exceptional spurious suppression throughout the millimeter-wave range. Frequency resolution of 0.01 Hz enables precise measurements on low-phase-noise oscillators and narrow-band signals.
What analysis bandwidth can the FSW50 achieve for wideband signal characterization?
The FSW50 provides 10 MHz analysis bandwidth as standard, with optional internal upgrades to 28 MHz, 40 MHz, 80 MHz, 160 MHz, 320 MHz, 512 MHz, 1200 MHz, or 2000 MHz. The R&S FSW-B2001/B800R option provides up to 2000 MHz analysis bandwidth. The YIG preselector must be switched off for frequencies at or above 12 GHz when using the 1200 MHz or 2000 MHz bandwidth options. This wide bandwidth capability supports 5G NR signal analysis, wideband radar testing, and advanced EW applications.
How does the displayed average noise level of the FSW50 perform across its frequency range?
With RF preamplifier off and 0 dB attenuation, the FSW50 achieves DANL of -149 dBm (typically -154 dBm) from 1 MHz to 1 GHz normalized to 1 Hz. From 8 GHz to 13.6 GHz with YIG preselector on, DANL measures -150 dBm (typically -155 dBm). At higher millimeter-wave frequencies from 18 to 25 GHz, the instrument maintains -147 dBm (typically -150 dBm). A built-in preamplifier option reduces the noise floor by over 15 dB, and noise cancellation adds 13 dB further improvement.
What are the third-order intercept point specifications for the FSW50 at millimeter-wave frequencies?
With RF attenuation at 0 dB, YIG preselector on, RF preamplifier off, and two tones at -20 dBm each, the FSW50 achieves TOI greater than 8 dBm (typically 11 dBm) from 8 GHz to 13.6 GHz. From 13.6 GHz to 40 GHz, TOI exceeds 10 dBm (typically 15 dBm). Above 40 GHz through the 50 GHz upper frequency limit, nominal TOI is 12 dBm, ensuring excellent linearity for multi-carrier and high-power measurements at millimeter-wave frequencies.
Does the FSW50 support measurements on 5G NR millimeter-wave signals?
Yes, with the optional R&S FSW-K144 and FSW-K145 5G NR measurement applications, the FSW50 provides comprehensive analysis of 3GPP 5G NR signals in both downlink and uplink, including FR2 millimeter-wave bands. The analyzer supports signal bandwidths from 5 MHz to 400 MHz, multiple numerologies, and modulation formats from QPSK to 256QAM. Wide internal analysis bandwidth options enable capture of complete 5G carriers for detailed EVM, power, and frequency analysis.
What is the SSB phase noise performance of the FSW50?
At a 1 GHz carrier, the FSW50 achieves SSB phase noise of -109 dBc (1 Hz) at 100 Hz offset (typically -116 dBc), better than -127 dBc (1 Hz) at 1 kHz offset (typically -132 dBc), and better than -145 dBc (1 Hz) at 1 MHz offset (typically -149 dBc). With the optional R&S FSW-B4 OCXO precision frequency reference, close-in phase noise at 10 Hz offset reaches -95 dBc (1 Hz) specified. Residual FM is below 0.1 Hz nominal at 1 GHz carrier.
Can the FSW50 measure harmonics of signals across its full 50 GHz range?
Yes, the FSW50 can characterize harmonic distortion with fundamentals measured up to 25 GHz and second harmonics observed through the 50 GHz upper limit. The second-harmonic intercept point is greater than 45 dBm (typically 55 dBm) for fundamental frequencies from 1 MHz to 500 MHz, and reaches 65 dBm nominal for fundamentals from 4 GHz to 42.5 GHz. This excellent harmonic suppression enables accurate measurements without requiring external filtering.
What real-time bandwidth is available on the FSW50 for transient signal capture?
The FSW50 supports real-time spectrum analysis up to 800 MHz bandwidth with the optional R&S FSW-B800R hardware option. Real-time mode provides 0.46 microsecond probability of intercept and processes 2.4 million FFT per second. This seamless analysis capability enables detection and capture of brief transient signals, frequency-hopping transmitters, and intermittent interference, with frequency mask triggers and I/Q data capture for automated event detection and post-analysis.
