==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, | |||
<blockquote> | |||
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. | |||
