    The S-4 Sampling Head is a 25 ps risetime unit with a 50 Ohm input impedance, and an equivalent badwidth from DC to 14 GHz. The S-4 can be plugged into the 7S11 or 7S12 Sampling units, or attached by a sampling head extender for remote use. A trigger pickoff within the S-4 provides a trigger signal output from the plug-in unit.

    The S4 Sampling Head has a 25 ps risetime, DC to 14GHz, 50 ohm input impedance. Variable DC Offset allows signals between +1 V and -1 V limits to be displayed at 2 mV/div. Displayed noise is >/= 5 mV unsmoothed, 2.5 mV smoothed (includes 90% dots).
