The Tektronix 80C11B is an optical sampling oscilloscope module engineered for high-speed optical signal analysis in 10 Gb/s datacom and telecom applications. This single-channel module delivers up to 30 GHz optical bandwidth across the long-wavelength spectrum, enabling precise characterization of NRZ, RZ, and optical duobinary signals. It integrates with Tektronix DSA8300 series and compatible sampling oscilloscopes to support conformance testing, extinction ratio and Q-factor measurements, eye pattern analysis, and compliance validation across standard and user-defined data rates.
