CSA7404B Tektronix Oscilloscope – Key Features and Benefits
The CSA7404B Tektronix oscilloscope is a high-performance real-time platform designed for precise signal analysis. It offers an impressive analog bandwidth of up to 4 GHz, with a rise time of 72 ps (20%–80%), making it ideal for high-speed signal testing. With a maximum waveform capture rate of over 400,000 wfms/s using DPX® technology, it ensures fast and accurate data acquisition. The oscilloscope features a 20 GS/s real-time sampling rate, allowing detailed analysis of complex signals. It includes built-in consistent mask testing, supporting optical and serial data streams up to 2.5 Gb/s. An integrated optical reference receiver helps maintain system calibration integrity, while hardware clock recovery simplifies setup and improves usability. With a record length of up to 64 MB, the CSA7404B enables deep signal inspection using MultiView Zoom™. It also supports 64-bit serial pattern analysis to isolate specific correlation effects. The device comes with a complete eye measurement kit, including parameters like extinction ratio, Q factor, eye height/width, jitter, and noise. Advanced waveform database acquisition technology allows for accurate parameter measurements on eye diagrams. The oscilloscope features a TekConnect® interface for high-fidelity connectivity and OpenChoice® architecture with Windows 2000 compatibility, offering built-in networking and analysis tools.
