The S3 sampling head is a plug-in head for use with the 7000 series sampling plug-ins or with the Type 3S2/3S5/3S6 samplers. The plug-in includes a permanently attached 1x probe with the sampling bridge enclosed in the probe.

The input rise time is specified as less than 350ps for the 1x probe, less than 400ps with the optional 10x attenuator tip, and less than 500ps with the 100x attenuator tip. The maximum operating signal voltage is 2Vp-p. The S3 does not provide a trigger pickoff for internal triggering. An offset voltage of either +/- 1V or +/- 2V can be selected via a toggle switch on the front panel.


Input Characteristics

The probe tip input is equivalent to 100k resistor in parallel with about 2.3pF capacitance at low frequency. With the 10x or 100x attenuator tips, the probe input is equivalent to 1M paralleled with 2pF or 1.7pF, respectively.
