Programming Fundamentals Getting Started with SCPI Subsystem Command Trees Most programming tasks involve subsystem commands that are usually specified to simulate front panel keystrokes. SCPI uses a hierarchical structure for subsystem commands similar to the file system on most computers. In SCPI, this command structure is called a command tree.
