The plug-in interface of the 580-series scopes is a single 16-pin Amphenol 26-series connector:

An unusual aspect of the 580 Series plug-in interface is the transmission line termination scheme for the plug-in output signal. The output signal passes from the plug-in, through the plug-in interface connector, through the first of two distributed amplifiers in the 580-series mainframe's signal chain, and then back into the plug-in, which contains 93 Ω resistors to match the characteristic impedance of each side the balanced transmission line.
