SCPI Conventions and Data Formats
The following SCPI conventions are used throughout this guide.
Angle brackets
< >
Items within angle brackets are parameter abbreviations. For
example, <NR1> indicates a specific form of numerical data.
Vertical bar
|
Vertical bars separate multiple parameter choices for a given
command string.
Square brackets
[ ]
Items within square brackets are optional. The brackets are not sent
with the command string. If you do not specify a value for an
optional parameter, the instrument chooses a default value.
Parenthesis
( )
Items within parentheses are used in place of the usual parameter
types to specify a channel list. The notation (@1:3) specifies a
channel list that consists of channels 1, 2, and 3. The notation
(@1,3) specifies a channel list that includes only channels 1 and 3.
Braces
{ }
Braces indicate parameters that may be repeated zero or more
times. It is used especially for showing arrays. The notation
<A>{,<B>} shows that parameter "A" must be entered, while
parameter "B" may be omitted, or may be entered one or more
times.
