The S-1 sampling plug-in head provides a single GR-874 50 Ω input with a 350 ps rise-time.
The S-1 can be used with the 7000 series of sampling plug-ins, as well as the 3S series of sampling units.

Internals
The S-1 uses a two-diode sampling gate which has relatively high "kick-out" (leakage of the strobe signal out of the input).
The manual cautions,
Operating the sampling head without the input connector terminated by a 50 Ω resistor or coaxial cable will cause a vertical shift of the zero signal baseline by a few millivolts. This is caused by the strobe kickout signal being reflected from the open input connector, and arriving back at the sampling bridge while the bridge is conducting.
The sampling bridge strobe signal is generated by an avalanche transistor followed by a step recovery diode, called snap-off diode in Tek lingo.
