Product Description

Product Overview

Rohde & Schwarz (R&S), a global leader in test and measurement equipment, has introduced the R&S®FSW67—a high-end signal and spectrum analyzer covering an ultra-wide frequency range from 2 Hz to 67 GHz. Designed for "high performance and multi-scenario adaptability," its core positioning addresses the precise measurement demands of RF, microwave, and even millimeter-wave (mmWave) applications, making it particularly suitable for cutting-edge communications, aerospace, defense electronics, and scientific research scenarios where measurement accuracy and functional scalability are paramount.

I. Core Specifications & Positioning

Frequency Range: 2 Hz to 67 GHz (direct coverage without external mixers; expandable to higher bands with R&S external mixer modules for millimeter-wave applications).
Instrument Type: Integrates "spectrum analysis" and "signal analysis" functions, supporting in-depth analysis of complex signals including continuous wave (CW), modulated signals (e.g., 5G NR, satellite communications), pulsed signals, and frequency-hopping signals.
Core Positioning: Targets high-end R&D (e.g., chip design, radar system development), stringent production testing (e.g., millimeter-wave device verification), and signal monitoring/compliance testing in aerospace/defense sectors.

II. Core Capabilities & Scalability

Standard Spectrum Analysis: Supports fundamental spectrum parameters including peak search, channel power, adjacent channel leakage ratio (ACLR), and spurious emission measurements.
Signal Analysis: Modulation analysis (amplitude/phase/frequency modulation), pulse signal analysis (pulse width, repetition period, duty cycle), power measurement (average power, peak power, peak-to-average ratio PAR).
Data Processing: Built-in signal recording and playback (stores massive raw signal data for offline analysis), multi-trace comparison (supports overlay analysis of results under different measurement conditions).

Optional Function Modules (Expandability)

Millimeter-wave Extension: When paired with R&S®FSW-Bxx series external mixers, the frequency range can be extended to 110 GHz, 325 GHz, or even higher, supporting millimeter-wave applications such as automotive radar (77/79 GHz) and satellite communications (Ka/Ku bands).
Real-Time Spectrum Analysis (RTSA): Activates real-time bandwidth (up to 250 MHz) via the optional R&S®FSW-K60 module, supporting "signal-triggered capture" (e.g., pulse triggering, level triggering) to capture transient signals.
Advanced Demodulation & Coding Analysis: The R&S®FSW-K100 module enables full demodulation of 5G NR millimeter-wave signals (including Massive MIMO parameter analysis), while the R&S®FSW-K70 module supports coding/decoding analysis of satellite communication signals (e.g., LDPC codes, Turbo codes).
Automation & Remote Control: Supports GPIB, LAN (LXI standard), USB, and other interfaces. Automated testing can be achieved via R&S®VISA software or custom SCPI commands (e.g., integration into unattended test systems on production lines).

III. Typical Application Scenarios

Communications: 5G NR mmWave, satellite links (VSAT, HTS), & IoT narrowband (LoRa).

Aerospace & Defense: Radar systems parameters, missile guidance RF validation, anti-jamming.

Research & Semiconductors: mmWave chips (MMICs), 6G pre-research, RF physical layer labs.

Industrial & Automotive: Automotive radar (77 GHz) calibration & IIoT signal monitoring.
