7S12
The Tektronix 7S12 is a TDR/Sampler plug-in for 7000-series scopes. It occupies two mainframe plug-in bays (one horizontal, one vertical).
The 7S12 has two bays for S-series plug-in modules ("heads"). The right bay accepts a pulse generator or a trigger recognizer plug-in, whereas the left bay accepts a sampling plug-in.
The typical configuration is to have an S-6 on the left and an S-52 on the right for time domain reflectometry, or an S-4 on the left and an S-53 on the right as a generaic sampler.
The 7S12 can also control an optional 7S11 through its side contacts, adding a second input channel.
Y axis can be scaled in voltage (mV) or distance (ρ) units, X axis in time or distance.
