See Clearer, Capture Faster

The RSA6000 Series devoloped by Rigol Technologies makes no compromises on RF performance, ensuring engineers can uncover every detail of their signals:

  • Up to 200 MHz real-time analysis bandwidth with 100% POI (Probability of Intercept) as low as 3.83 μs, making transient signals like frequency hopping and pulses fully visible.
  • In Real-Time Spectrum Analysis (RTSA) mode, scanning speeds up to 4 THz/s enable rapid scanning of ultra-wideband spectra, greatly enhancing efficiency in spectrum monitoring and interference detection.
  • Frequency coverage from 5 kHz to 26.5 GHz, supporting diverse testing scenarios from low-frequency communications to microwave radar.
  • Exceptional phase noise performance as low as -108 dBc/Hz @1GHz, 10kHz offset, providing a clean benchmark for evaluating critical components like oscillators and phase-locked loops.
  • DANL (Displayed Average Noise Level) as low as -163 dBm/Hz (typ.), for effortless capture of weak signals.

Five Modes, One Versatile Instrument

The RSA6000 Series deeply integrates five core measurement modes, allowing one-click switching to transform into specialized analysis tools, meeting engineers' needs across various testing phases.

  • General Purpose Spectrum Analysis (GPSA): A powerful traditional swept analysis mode offering automated measurements such as channel power, adjacent channel power ratio (ACPR), occupied bandwidth (OBW), and harmonic distortion.
  • Real-Time Spectrum Analysis (RTSA): Utilizes density maps, spectrograms, and PvT views to intuitively display time, frequency, and amplitude changes in complex signals—ideal for resolving inter-channel interference, spectrum monitoring, and frequency-hopping signal analysis.
  • Vector Signal Analysis (VSA): Optional demodulation analysis with 200 MHz vector demodulation bandwidth, easily handling various wideband communication signals through constellation diagrams, eye diagrams, EVM, and other parameters for comprehensive transmitter quality assessment.
  • Analog Demodulation (ADM): Supports in-depth analysis of AM/FM/PM analog modulated signals, automatically measuring key parameters like carrier power, modulation depth, and frequency deviation.
  • EMI Pre-Compliance Analysis (EMI): Built-in CISPR-compliant filters for pre-testing conducted and radiated emissions, identifying and mitigating conducted/radiated disturbance sources to accelerate product time-to-market.

Flexible Deployment, Seamless Collaboration

The RSA6000 Series breaks free from the constraints of traditional benchtop instruments, delivering unprecedented flexibility for engineers.

  • Touch-Optimized UI Design: A brand-new touch UI provides a tablet-like smooth experience, making complex spectrum measurements intuitive, efficient, and effortless.
  • Web Control and Remote Collaboration: Access the full instrument control interface and view real-time results via any web browser—no software installation required. Whether you're on-site or remote, enable monitoring, collaborative debugging, or educational demonstrations from anywhere.
  • Rich Interfaces and Programmability: Standard HDMI, LAN, USB interfaces, plus a complete SCPI command set and driver support for quickly building automated test systems.

With one-click mode switching, web-based remote collaboration, and a lightweight design for grab-and-go portability, the RSA6000 serves as engineers' core platform throughout R&D, validation, and troubleshooting—truly packing a high-end experience into a portable spectrum workstation.

Versatile Powerhouse: Tackling Diverse Testing Challenges

Whether in cutting-edge scientific research or demanding industrial applications, this spectrum analyzer delivers comprehensive solutions. In wireless communications and RF testing, it enables deep characterization and validation of components and systems. During electronics R&D and production, it helps engineers pinpoint noise interference sources and ensures fast compliance testing on production lines. For spectrum monitoring tasks, its superior transient signal capture ensures rogue signals have nowhere to hide. In EMI pre-compliance testing, it's an invaluable tool for quickly identifying conducted and radiated issues, speeding up product launches.
