S-parameter measurements with a TDR provide powerful insight into signal integrity performance in high-speed and RF systems. By sending a fast step pulse into a device under test, a Time Domain Reflectometer detects impedance discontinuities and signal reflections. The measured time-domain response is mathematically converted into frequency-domain S-parameters such as S11 (return loss) and S21 (insertion loss). BitWise Laboratories offers advanced TDR solutions that combine precise step generation, accurate sampling, and S-parameter extraction. This approach enables engineers to quickly analyze reflections, transmission behavior, and overall performance for reliable high-speed electronic design.
