Keysight Phase Noise Analyzers
视频
This video introduces Keysight’s Phase Noise Analyzer portfolio, engineered for high‑sensitivity phase noise and spurious analysis across a wide range of signal sources and applications. These analyzers deliver exceptionally low noise floors—down to the kT thermal noise limit on the highest‑end models—enabling engineers to detect the lowest levels of phase noise and ensure reliable performance of oscillators, synthesizers, clocks, and RF subsystems.
Keysight phase noise analyzers utilize dual‑channel cross‑correlation to actively suppress internal instrument noise. This technique improves measurement accuracy and stability by isolating true device‑under‑test noise from internal contributions, resulting in precise absolute, residual, and additive phase noise characterization. Purpose‑built analysis capabilities make it easy to evaluate both component‑level and system‑level performance.
In addition to phase noise, these analyzers measure AM noise and baseband noise—critical contributors to EVM degradation in digital modulation schemes—allowing complete signal quality assessment for advanced wireless systems.
Supporting maximum frequencies up to 54 GHz and large offset frequency ranges, Keysight’s phase noise solutions address demanding applications in high‑frequency design, radar, 5G, satellite communications, and precision time‑keeping systems. A range of model options ensures the right fit for diverse measurement needs.
