The Tektronix S-6 Sampling Head plug-in is a 50 Ω feed-through unit with a rise-time of 30 ps and bandwidth of 11.5 GHz. It was introduced in 1971.
The S-6 provides two unterminated 50 Ω SMA connections in a loop-through configuration as is convenient for TDR applications. It is good practice to leave a termination resistor on the unit when unused to give some protection against electrostatic discharge.
