 and the horizontal voltage from the oscilloscope can be used to control the 1S1, as described below.
-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.
 With the 1S1's internal sweep disabled, the horizontal-in and vertical-out connections can be used
-so the the 1S1 acts as a lookup table, a mapping of x to y, a function.

 The 661 also has this capability, in its "A vert/B horiz" mode, which is like X-Y mode for a sampler.
 In this mode, the horizontal-in voltage controls the time after the trigger event when the sample should be taken,
