The HP/Agilent 11982A Amplified Lightwave Converter performs optical-to-electrical (O/E) signal conversion with integrated amplification, translating high-speed optical signals into measurable RF electrical signals. This capability enables analysis of optical phenomena using standard electrical test instruments—oscilloscopes, spectrum analyzers, BERT systems, and network analyzers—extending their utility into the optical domain for component and system characterization.
