STB R1 is a signal integrity teaching and verification platform designed for high-frequency hardware engineers, RF engineers and university electronics laboratories. It highly integrates the core basic functions of signal integrity testing onto a single independent PCB, with on-board VNA calibration kit and various typical transmission line topologies. Focusing on transmission line effect research and VNA measurement practice, it effectively lowers the entry barrier and helps users quickly get started with high-frequency PCB S-parameter measurement, impedance analysis and signal quality evaluation. Widely applicable to signal integrity teaching demonstrations in university electronics labs, transmission line effect research and impedance matching debugging for RF engineers, model verification for SI/PI simulation engineers, as well as testing and troubleshooting of long/short stub notch characteristics, serpentine trace crosstalk (NEXT) and planar antenna (EMI/EMC) in high-frequency PCB design. It is an ideal tool to assist R&D personnel in high-frequency signal quality evaluation and design optimization.
