when it is connected to the Video output
connector (24-pin D-Sub) on the rear panel.
The external trigger input terminal (BNC) on the
rear panel allows an external trigger source to be
used for measurement trigger.
The GPIB compatibility allows the E5072A to be
operated as a talker/listener on IEEE 488
interface bus.
