The broad-wavelength 80C08C optical sampling module is a hardware plug-in for the Tektronix 8000 Series Communications Signal Analyzer family. The module offers the accuracy, signal-to-noise performance, and optical sensitivity to meet the development and production test needs of low-cost directly-modulated laser devices used in10 gigabit Ethernet (10GbE) components and equipment. The module is designed to support narrow measurement margins in production, maximizing yield.
