Command Syntax
You can control the operations and functions of the oscilloscope through the
Ethernet port or the USB 3.0 super speed (SS) device port using commands and
queries. The related topics listed below describe the syntax of these commands
and queries. The topics also describe the conventions that the oscilloscope uses
to process them. See the
Command Groups
topic in the table of contents for a
listing of the commands by command group, or use the index to locate a speci
fi
c
command.
Backus-Naur Form
Notation
This documentation describes the commands and queries using Backus-Naur
Form (BNF) notation. Refer to the following table for the symbols that are used.

Command and Query Structure
Commands consist of set commands and query commands (usually called
commands and queries). Commands modify oscilloscope settings or tell the
oscilloscope to perform a speci
fi
c action. Queries cause the oscilloscope to return
data and status information.
Most commands have both a set form and a query form. The query form of the
command differs from the set form by its question mark at the end. For example,
the set command
ACQuire:MODe
has a query form
ACQuire:MODe?
. Not all
commands have both a set and a query form. Some commands have set only and
some have query only.
Messages
A command message is a command or query name followed by any information
the oscilloscope needs to execute the command or query. Command messages
may contain

ve element types, de
