If the menu key requires several entries to be made in a dialog or in a wizard (e.g. the S-
Param Wizard), the command opens this dialog/wizard. All entries can be made manually.
The instrument is switched back to remote control mode as soon as the dialog or wizard is
closed.
DISPlay:MENU:KEY:EXECute '<menu_key>'
works for all menu keys, even though the
analyzer may not provide an equivalent remote control command.

The messages transferred on the data lines of the GPIB bus or via the RSIB / VXI-11 interface can be
either interface messages or device messages.
GPIB Interface Messages
GPIB interface messages are transferred on the data lines of the GPIB bus, the ATN control line being
active. They are used for communication between controller and instrument and can only be sent by a
computer which has the function of an GPIB bus controller.
GPIB interface messages can be further subdivided into
Universal commands act on all devices connected to the GPIB bus without previous addressing.
Addressed commands only act on devices previously addressed as listeners.
The interface messages relevant to the instrument are listed in the GPIB bus section.
RSIB and VXI-11 Interface Messages
The RSIB and VXI-11 interfaces allow the instrument to be controlled in a Local Area Network. For a short
introduction and a list of interface functions refer to the following sections:

Device Messages (Commands and Device Responses)
Device messages are transferred via the data lines of the GPIB bus, the "ATN" control line not being
active. The ASCII character set is used. A distinction is made according to the direction in which device
messages are transferred:
Commands are messages the controller sends to the instrument. They operate the device
functions and request information.
