The Tektronix P6703B is an optical-to-electrical converter probe that transforms optical signals into electrical signals for precise measurement on compatible oscilloscopes. Engineered for optical communication system characterization, the P6703B delivers high-fidelity signal acquisition across demanding testing applications including eye pattern analysis, extinction ratio measurement, and optical pulse shape evaluation in SONET/SDH and Fibre Channel environments.
