5000 Series plug-in interface
Tektronix 5000 series oscilloscope mainframes have two vertical plug-in slots, and one horizontal plug-in slots.
The interconnect on either slot type is a 56-pin PCB edge connector.
Looking into the mainframe from the front panel, "A" pins are left of the connector centerline and "B" are on the right. Pins are numbered from 1 at the bottom to 28 on the top.
The table below shows the connections as if looking through the back of the mainframe or at the back of a plugin.
