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.

Measurements
-
Impulse taken with S6 sampling head. Every dot is equivalent to one sample taken, and combined on the CRT with a rate of app. 100 Hz. Bright dots are newer than dimmed ones.
-
Incident pulse from an S-52 (nom. < 25 ps) displayed by an S-6 head (nom. < 30 ps), both installed in a 7S12. Displayed rise time ~35 ps confirms spec.
