FSW85 Signal and Spectrum Analyzer 2Hz-85GHz
SW85 Signal and Spectrum Analyzer: A Core Tool for High-Precision RF Testing I. Core Technical Specifications Analysis As Rohde & Schwarz's flagship signal and spectrum analyzer, the FSW85 boasts industry-leading technical parameters: Ultra-wide Frequency Coverage: The basic frequency range is 2 Hz to 85 GHz, expandable to 500 GHz with an external harmonic mixer. This feature allows it to cover the full frequency range from low-frequency communication to millimeter-wave radar and terahertz research, particularly excelling in testing for 5G NR millimeter-wave bands (such as 26 GHz, 28 GHz) and automotive radar 77-81 GHz bands. Exceptional Phase Noise Performance: At a 1 GHz carrier and 10 kHz offset, the phase noise is as low as -137 dBc/Hz, far exceeding similar products. This excellent background noise control capability enables the FSW85 to accurately capture weak echo signals in radar system development while supporting high-precision oscillator phase characteristic analysis. Wide Dynamic Range and High Resolution: The WCDMA adjacent channel power ratio (ACLR) test dynamic range is up to 88 dB (with noise cancellation enabled), effectively separating the main carrier and adjacent channel interference in complex signals. Coupled with an adjustable resolution bandwidth (RBW) from 1 Hz to 10 MHz, it enables fine-grained analysis of signals from narrowband to broadband modulated signals. Real-time Spectrum Analysis Capability: Built-in 800 MHz real-time bandwidth captures transient signals (such as pulsed radar, frequency-hopping communication), avoiding signal loss issues with traditional scanning analysis. Combined with a maximum analysis bandwidth of 5 GHz (expandable via an external digital converter), it can fully analyze the transient characteristics of 5G NR downlink 200 MHz bandwidth signals. Intelligent Operating Interface: Equipped with a 12.1-inch high-resolution multi-touch screen, it supports Windows 10 and gesture operation. The multi-window parallel display function allows simultaneous operation of multiple tasks such as spectrum analysis, modulation analysis, and phase noise testing, significantly improving the efficiency of multi-parameter joint debugging. II. Key Functional Features and Innovative Multi-scenario Measurement Applications In-depth Modulation Signal Analysis: Supports vector signal analysis of standards such as LTE, 5G NR, and WLAN, measuring parameters such as error vector magnitude (EVM), constellation diagrams, and power spectral density to meet the R&D and testing needs of base stations and terminal chips. Radar-Specific Analysis Tools: Integrates optional modules such as pulse measurement (R&S FSW-K6) and linear frequency modulation signal analysis (R&S FSW-K60), allowing one-click acquisition of key indicators such as pulse width, repetition frequency, and frequency modulation slope, suitable for the design verification of automotive radar and weather radar. Satellite Communication Testing: Through DVB-S2X, OneWeb, and other protocol demodulation functions, it can perform high-precision measurements of group delay and gain flatness of satellite payloads, ensuring the reliability of aerospace communication systems. Automation and Integration Capabilities: The built-in SCPI recorder automatically generates test codes, simplifying the collaborative operation process with external devices (such as signal sources and oscilloscopes). The modular design supports the expansion of I/Q demodulation bandwidth modules to meet the flexible configuration requirements of customized test systems. Low Uncertainty Measurement: In the frequency band below 8 GHz, the total measurement uncertainty is less than 0.4 dB. Coupled with a high-precision calibration algorithm, it ensures the traceability of measurement results for parameters such as gain and harmonic distortion of RF devices (such as amplifiers and filters).
