VX4792 User Manual
A large set of commands can be used to control the operations and functions of
the VX4792 Arbitrary Waveform Generator from an external controller. The
Command Syntax section describes the syntax and communication rules for
using these commands to operate the waveform generator.
Be sure to read this section before attempting to send commands to your
waveform generator.
The command syntax is in extended BNF (Backus-Naur Form) notation. The
extended BNF symbols used in the command set are shown in the Table 3–1.

Symbol Meaning
< > Indicates a defined element
| Delimits Exclusive OR elements
{ } Delimits a group of elements one of which the programmer must select
[ ] Delimits an optional element that the programmer may omit
[ ]... Delimits an optional element that the programmer may omit or may repeat
one or more times
::= Indicates that the left member is defined as shown by the the right member
Programs created or placed in an external controller are transferred to the
VX4792 Arbitrary Waveform Generator as a program message. A program
message is a sequence of zero or more program message units delimited by the
program message unit delimiter, the semicolon (;).
A program message unit is a set command or query command. The waveform
generator performs a function or changes a setting or mode when it receives a set
command; when the waveform generator receives a query command, it returns
measurement data, settings, status codes and/or status messages. The waveform
generator transfers these response messages to the external controller.
