Description
Overview
The Tektronix S-4 is a high-speed sampling gate designed for precision signal measurement. It employs a traveling wave trapped-charge transmission line technique that provides a high-bandwidth signal path through a special coaxial connector. The design requires only a sharp pulse edge rather than a precise pulse width, making it highly effective for transient and timing measurements. The S-4 features 50Ω input impedance and can be used with various sampling plugins or as a remote unit via a sampling head extender.
