7000 Series plug-in interface
The 7000-series scopes have two categories of slots, horizontal and vertical, that have partly different but compatible interconnects so that vertical pplugins can be installed in horizontal slots and vice versa, but not with all functions.
The interconnect is a 76-pin PCB edge connector. Pinout is given in the following table, where (H) indicates signals available in horizontal slots only, and (V) denotes signals available in vertical slots only.
