The Tektronix 3S1 is a dual-trace sampling plug-in for 560-series scopes.
In contrast to modular sampling plug-ins like the 3S2, the 3S1 has built-in sampling heads. The signal enters through 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.
In many ways, the 3S1 is similar to the 4S1, but more compact.
The 3S1 provides +100 V and −12.2 V for P6032 cathode-follower probes.
