Command Syntax
Abbreviating Commands,
Queries, and Parameters
You can abbrevi
ate most SCPI commands, queries, and parameters to an accepted
short form. This manual shows these commands as a combination of upper and
lower case letters. The upper case letters indicate the accepted short form of a
command, as shown in the following figure. The accepted short form and the long
form are equivalent and request the same action of the instrument.

Chaining Commands and
Queries
You can chain several commands or queries together into a single message. To
create a chained message, first create a command or q
uery, then add a semicolon
(;), and finally add more commands or queries and semicolons until you are done.
If the command following a semicolon is a root node, precede it with a colon
(:). The following figure illustrates a chained message consisting of several
commands and queries. The chained message should end in a command or query,
not a semicolon. Responses to any queries in your message are separated by
semicolons.
Figure 2-4: Example of chaining commands and queries
If a command or query has the same root and lower-level nodes as the previous
command or query, you can omit these nodes. In the following figure, the second
command has the same root node (STAT:QUES) as the first command, so these
nodes can be omitted.
