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.
