Describes the six-diode traveling-wave sampler implemented in the S-4 and S-6 sampling heads. George Frye refers to this circuit as a "velocity gate" due to the fact that it relies only on the sampling pulse having high dv/dt. In contrast, four-diode and two-diode sampling gates rely on the sampling pulse having high d²v/dt² in order to turn the sampling gate on and then off within a tiny duration.
