The Tektronix 3S76 is a dual-trace sampling plug-infor 560-series scopes. The inputs have 50-ohm impedance and use GR-874 connectors. The risetime is rated at less than 0.4ns. Each input has a trigger takeoff transformer and a 55ns coaxial delay line. The trigger source channel is selectable. Each delay line terminates at that channel's sampling bridge, which is a four-diode design using beam-lead GaAs diodes. A 7586 nuvistor buffers the output of each sampling bridge. The sampling pulse, common to both channels, is generated by a snap-off diode and a 3cm twisted-pair clipping line.
