 The '''Tektronix Type 3S1''' is a dual-trace [[sampling_oscilloscope|sampling]] plug-in for [[560-series scopes]].  The risetime is 350 ps.
-In contrast to modular sampling plug-ins like the [[3S2]], the 3S1 has built-in sampling heads.  The signal enters through [[Connectors#GR-874|GR-874 connectors]] on the front panel.  Each channel has a resistive trigger pickoff followed by a 55 ns coaxial [[delay line]].  Following the delay line is a compensation circuit designed to (partially) undo the pulse degradation caused by the delay line, and also to provide proper termination for low return loss at the input.

 Next in the main signal path is a four-diode sampling bridge driven by a [[snap-off diode]], D73.
