+The '''Tektronix 7S11''' is a [[sampling oscilloscope|sampling]] plug-in for [[7000-series scopes]].
+It takes one [[:7000 and 3S series sampling heads|S-series sampling head]], e.g. [[S-4]] or [[S-6]], to form a complete vertical plug-in.
+Bandwidth and sensitivity are determined by the sampling head, not the plug-in.
-For operation a [[7T11]] plug-in is needed.
+For operation, a [[7T11]] or [[7S12]] plug-in is needed, to which the 7S11 connects through [[7000-series Sampling Shoe|contact strips on the right side of the plug-in]].
+The control signals are routed to a similar strip on the left of the module for another 7S11 in a dual-channel configuration.
+An alternative configuration consists of a pair of 7S11s, one in the right vertical and the other in the A or only horizontal bay,
+for an X-Y display in free-running mode (~50 kHz strobe).

+The DC offset voltage as well as the vertical display signal are accessible on the front panel through [[Pin Tip]] jacks.
