The S50 Pulse Generator Head is a high-speed,
tunnel-diode step generator designed for use with 7S11, 3S2, 3S5, 3S6, 7S12,
285, and 286. The unit is also used for verification of sampling system
risetimes. A pretrigger output allows operation with sequential sampling
systems. 25 ps pulse risetime; 400 mV pulse amplitude; 100 ns pulse width
