Keysight Signal and Spectrum Analyzers

This video introduces Keysight’s Signal and Spectrum Analyzer portfolio—Essential, Expert, and Pro—engineered to deliver the accuracy, bandwidth, and real-time performance required for modern RF, microwave, and millimeter-wave testing. With low phase noise, high dynamic range, and excellent repeatability, these analyzers provide precise insight into complex signal environments across research, development, and validation workflows.

Real-time spectrum analysis captures transient events without gaps, enabling engineers to detect interference, spurious emissions, and fast signal changes that traditional swept methods may miss. Frequency coverage up to 110 GHz and analysis bandwidths up to 4 GHz support advanced wireless research, including 5G NR, emerging 6G waveforms, radar systems, and high-speed communications. To address varying performance needs, the portfolio is organized into three performance grades:

• Essential signal and spectrum analyzers support up to 50 GHz and 510 MHz analysis bandwidth, offering dependable, cost‑effective performance for foundational RF testing, general-purpose debugging, and education environments. With DANL performance down to –167 dBm at 1 GHz, these analyzers provide excellent sensitivity for low‑level signal work.

• Expert signal and spectrum analyzers extend reach with frequency ranges up to 55 GHz, analysis bandwidth up to 2 GHz, multi‑touch user interfaces, and real‑time capabilities ideal for protocol development, standards compliance, and advanced signal characterization. These analyzers serve high‑performance communications, aerospace, and defense engineering workflows.

• Pro signal and spectrum analyzers represent Keysight’s highest‑performance platforms, supporting frequencies up to 110 GHz with 4 GHz analysis bandwidth and full real‑time spectrum analysis. Designed for next‑generation R&D, they enable wideband modulation analysis, complex signal environment emulation, and validation of the most advanced wireless and radar systems.

Across all tiers, Keysight Signal and Spectrum Analyzers integrate more than 75 software tools for demodulation, standards‑based testing, vector signal analysis, and in‑depth diagnostics—ensuring engineers can quickly transition from signal capture to actionable insights.
