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 orriving bock at the sampling bridge while the bridge is conducting.
