  • Specification

The Anritsu MS2850A is a high-performance signal and spectrum analyzer developed for evaluating wideband communication systems such as 5G and satellite networks. It features an industry-leading 1 GHz analysis bandwidth, supporting comprehensive evaluation of multicarrier and millimeter-wave signals, while maintaining high amplitude and phase accuracy for each carrier.

This benchtop analyzer provides a robust solution for RF performance testing, modulation accuracy, and EVM measurements. Thanks to its high ADC clipping level and exceptionally low Displayed Average Noise Level (DANL), it achieves a reference dynamic range of up to 142 dB, allowing precise capture of real-world wideband signals without distortion.

Engineers can leverage its large 32 GB capture memory to store up to 24 seconds of real-time signal data (at 100 MHz span), which can be post-processed in external EDA tools for deeper analysis. The analyzer also features spectrogram and FFT-based visualization, ideal for observing changes in frequency and phase over time.

Its modular options include bandwidth upgrades and high-speed PCIe/USB 3.0 data interfaces, making it an efficient and scalable choice for both research labs and production lines. Whether you're developing 5G chipsets, verifying satellite transmission quality, or conducting compliance testing, the MS2850A offers the power and flexibility needed for high-fidelity signal analysis.

  • Frequency Range: 9 kHz to 32 GHz / 44.5 GHz.

  • Analysis Bandwidth: Standard 255 MHz, optional upgrades to 510 MHz and 1 GHz.

  • Memory Capture: Up to 24 seconds at 100 MHz span using 32 GB memory.

  • Wideband Coverage: Sub-6 GHz to mmWave (28/39 GHz), ideal for 5G and satellite systems.

  • High Dynamic Range: Up to 142 dB (ref.) at 28 GHz with high ADC clipping level and low DANL.

  • Excellent Flatness: ±1.2 dB amplitude and 5° p-p phase linearity at 1 GHz bandwidth.

  • High SFDR: -70 dBc across 4.2–44.5 GHz range for clean wideband signal analysis.

  • FFT-Based Analysis: Includes spectrum, spectrogram, and phase variation tracking.

  • EDA-Compatible Output: Allows external signal analysis via digitized waveform export.

  • PCIe/USB 3.0 Option: Supports fast transfer of large data sets for efficient R&D workflows.
