The 1S1 has a 50 Ω [[GR-874 connector]] for signal input.  The plug-in supplies power (+100 V and -12.6 V) to accessories like the [[P6032]] Cathode Follower Probe, the [[281]] TDR Pulser, and the [[282]] Probe Adapter.

The 1S1 can operate in normal self-swept mode or an external sweep signal can be applied to the 1S1.
