The SD-42 Optical-to-Electrical Converter Head is a high-performance optical head for use in the 11800 Series Digital Sampling Oscilloscopes (including the SM-11 Multi-channel Unit) and the CSA 803 Communications Signal Analyzer. The SD-42 Optical-to-Electrical Converter Head is used with SD-22, SD-24, and SD-26 Sampling Heads. The SD-42 converts an optical signal into an electrical signal which serves as the input to an SD Series Sampling Head.
The SD42 Optical-to-electrical Converter head can be used to analyze optical signals in the 1000 nm to 1700 nm wavelength range. The pulse response of the measurement system is less than 55 ps FWHM (Full-width, Half-maximum), which is equivalent to a calculated bandwidth of DC to 6.4 GHz. The electrical output on the front panel is coupled to the adjacent sampling head via the semi-rigid coaxial link provided.
