The Tektronix S-4 is a high-speed oscilloscope sampling head designed for use in compatible Tektronix sampling plug-ins such as the 7S11, 7S12, and 3S2. It provides an equivalent bandwidth of 14 GHz with a risetime of 25 ps or less, making it suitable for ultra-fast time domain measurements and high-resolution TDR applications. The S-4 features a 50-ohm input impedance and is equipped with a 3 mm SMA male connector.
