3. SCPI Requirements

3.1 Introduction to SCPI

3.1.1 Command Format

SCPI commands are tree-like hierarchical structures, including multiple
subsystems, each of which consists of a root keyword and one or more
hierarchical keywords. The command line usually starts with a colon ":";
keywords are separated by colons ":", followed by optional parameter settings; a
question mark "? " is added after the command line to indicate a query for this
function; commands and parameters are separated by "spaces".

3.1.2 Explanation of symbols

1、 big parantheses { }
The content in curly brackets is the parameter options. Parameter items are
usually separated by a vertical line "|". When using a command, you must select
one of the parameters.
2、 Vertical Line |
The vertical bar is used to separate multiple parameter options. When using a
command, you must select one of the parameters.
3、 Square brackets [ ]
The text in square brackets is optional.
Page 9
5
4、 Triangle brackets < >
The parameters in the triangle brackets must be replaced by a valid value.

3.1.3 Parameter Types

1、 Bool
The parameter values are "OFF", "ON", "0", or "1".
2、 Discrete
The parameter values are the listed options.
3、 Integer
Unless otherwise specified, the parameter can be any integer (NR1 format) within
the valid value range. Note that please do not set the parameter to decimal
format at this time, otherwise an exception will occur.
4、 Real
The parameter can be any real number within the valid value range. The
command accepts parameter input in decimal (NR2 format) and scientific
notation (NR3 format).
5、 ASCII string
The parameter value is a combination of ASCII characters.
Page 10

3.1.4 Command abbreviation

All commands are not case sensitive and can be all uppercase or lowercase.
However, if you want to abbreviate, you must enter all capital letters in the
command format.
