Dual-beam scopes contain CRTs with two separate electron guns, producing separate electron beams that can be deflected independently for displaying different signals.
Depending on the tube, the beams may share horizontal deflection plates, or may have completely separate deflection.
Scopes that use electronic multiplexing to display more than one signal using just one electron beam are called multi-trace (dual-trace, quad-trace) scopes.
Some dual-beam scopes allow displaying multiple traces per beam by using dual- or quad-trace plugins.
Tektronix produced the following true dual-beam models:
