IEEE 488.2 BUS OPTION
If installed you will find here the input/output
socket to connect the oscilloscope to an
IEEE 488 interface.
The external conductor of the BNC sockets
and the screening of the interface bus
connectors are internally connected to the
protective earth conductor of the three-core

BNC sockets and the screening of the
interface bus connectors must not be used as
a protective conductor terminal.
