Programming convention
Tree concept
The SCPI commands have a branching structure.
A command must end with a terminator, <NL> or <;>.
If commands are separated by the character <;> and are located in the same directory, there is
no need to repeat the whole tree. Otherwise, use the <:> character followed by the full name of
the command.
 Example
DISP:TRAC:STAT1 1<NL>
DISP:TRAC:STAT2 1<NL>
equivalent to:
DISP:TRAC:STAT1 1; STAT2 1<NL>
equivalent to:
DISP:TRAC:STAT1 1; DISP:TRAC:STAT2 1<NL>
Command syntax
Common commands

Specific commands
Key words
Square brackets ([]) enclose a key word that is optional in the programming. Upper-case and
lower-case are used to differentiate the short form of a key word (upper-case letters) from the
long form (whole word).
The instrument accepts upper-case and lower-case letters without distinction.
 DISP:TRAC:STAT 1 is equivalent to DISPLAY:WINDOW:TRACE:STATE 1
Separators
": "
goes down to the next directory or returns to under the root, if preceded by a ";"
"; "
separates 2 commands in the same directory
" "
(space) separates the key word from the next parameter
","
separates one parameter from the next
Parameters
<>
The parameters of a specified type are noted by the characters shown opposite.
[]
The square brackets mean that the parameter(s) are optional.
{ }
The braces define the list of allowed parameters.
|
The vertical bar can be read as "or". It is used to separate the various possible parameters.
