 The S-3 sampling head is a plug-in head for use with the
 series sampling plug-ins or with the Type [[3S2]], [[3S5]], or [[3S6]] samplers.
-The plug-in includes a permanently attached 1x probe with the sampling bridge enclosed in the probe.
+The plug-in includes a permanently attached 1× probe with the sampling bridge enclosed in the probe.  Optional 10× or 100× attenuator tips are available.
-The input rise time is specified as less than 350 ps for the 1× probe, less than 400 ps with the optional 10× attenuator tip, and less than 500 ps with the 100× attenuator tip.
+==Specifications==
-The maximum operating signal voltage is 2 V<sub>p-p</sub>.
-The S-3 does not provide a trigger pickoff for internal triggering.
-An offset voltage of either +/- 1 V or +/- 2 V can be selected via a toggle switch on the front panel.
-== Input Characteristics ==
+* Input rise time:
-The probe tip input is equivalent to 100 kΩ resistor in parallel with about 2.3 pF capacitance at low frequency.
+** 1×: < 350 ps
-With the 10× or 100× attenuator tips, the probe input is equivalent to 1 MΩ paralleled with 2 pF or 1.7 pF, respectively.
+** 10×: < 400 ps
+** 100×: < 500 ps
+* Input impedance:
+** 1×: 100 kΩ || 2.3 pF at low frequency
+** 10×: 1 MΩ || 2 pF
+** 100×: 1 MΩ || 1.7 pF
+* Maximum signal voltage: 2 V<sub>p-p</sub>
+* The S-3 does not provide a trigger pickoff for internal triggering.
+* An offset voltage of either +/- 1 V or +/- 2 V can be selected via a toggle switch on the front panel.
