Specifically designed for communications applications, the CSA803C Communications Signal Analyzer is the ideal tool for design and evaluation of datacomm/telecomm components, transceiver subassemblies, and transmission systems. The CSA803C Sampling Oscilloscope generates measurement results, not just raw data, with time and voltage histograms, mask testing, and statistical pulse parameter measurements. In addition, mask testing of SDH/SONET, Fiber Channel, and other standards simplifies compliance testing. A full color display helps you to discriminate waveform details. A color-graded display mode adds a third dimension - sample density - to your signal acquisitions and analysis. In addition to its full-function DC-coupled 4.0 GHz trigger (typical), the CSA 803C offers a built-in, AC-coupled 12.5 GHz (typical) prescaler trigger for direct triggering on high-speed data at bit rates such as 9.953 GB/S OC192/STM64. The unit has a bandwidth of dc to 50GHz with the SD-32 plug-in (sold seperately) Features DC to 50 GHz with up to 12.5 GHz Trigger Bandwidth Design and Evaluation of Datacomm/Telecomm Components, Transceiver Subassemblies, and Transmission Systems. Fully Automatic Jitter, Noise, and Extinction Ratio Measurements Normal, Infinite, Variable Persistence, and Color Graded Display Modes Compatible with Optional O/E Converters Automatic Measurements on Eye-diagrams Time and Voltage Histograms Automated ITU/ANSI Mask Testing with 47 Predefined Standard Masks Requires SD series plug-in modules for signal inputs
