Keysight Optical Modulation Analyzers
Videos
This video introduces Keysight’s Optical Modulation Analyzer (OMA) portfolio, designed for deep analysis of complex coherent optical signals used in next‑generation data communication systems. These OMAs combine a high‑bandwidth real‑time oscilloscope with a coherent optical receiver, enabling precise measurement and characterization of high‑speed modulation formats.
Supporting symbol rates up to 220 GBd, Keysight OMAs are ideal for validating ultra‑high‑speed coherent links such as those found in emerging 800ZR and beyond‑800G networks. The systems provide powerful vector signal analysis capabilities — including constellation diagrams, EVM measurements, and advanced polarization analysis — delivering critical insights into signal impairments, noise, and system performance.
With upgradeable hardware, users can scale bandwidth, channel count, and analysis functionality as standards evolve and test needs advance. Multiple calibrated receiver options, including C‑band, L‑band, and O‑band, support a wide range of wavelength requirements and application spaces.
Keysight OMAs feature up to 110 GHz of bandwidth, 256 GSa/s sample rates, and advanced analysis software that enables system‑level evaluation across diverse coherent modulation formats. Designed for high‑speed research, development, and validation, OMAs deliver the insight needed to advance coherent optical system performance.
