SCPI commands are [[ASCII]] textual strings,<ref name="IVI-SCPI"/> which are sent to the instrument over the physical layer.<ref name="IVI-SCPI"/> Commands are a series of one or more keywords, many of which take parameters. In the specification, keywords are written <code>CONFigure</CODE>: The entire keyword can be used, or it can be abbreviated to just the uppercase portion. Responses to query commands are typically ASCII strings. However, for bulk data, binary formats can be used.<ref name="SCPI-1999-spec"/>

The SCPI specification consists of four volumes: Volume 1: "Syntax and Style", Volume 2: "Command Reference", Volume 3: "Data Interchange Format", Volume 4: "Instrument Classes".<ref name="SCPI-1999-spec"/> The specification was originally released as non-free printed manuals, then later as one free [[PDF]] file that includes all four volumes.<ref name="SCPI-1999-spec"/>
