3.3.5.4 PROGRAM MESSAGE STRUCTURE
SCPI program messages (commands from controller to power supply) consist of one or more
message units ending in a message terminator. The message terminator is not part of the syntax; it
is defined by the way your programming language indicates the end of a line (such as a “new-
line” or “end-of-line” character). The message unit is a keyword consisting of a single command
or query word followed by a message terminator (e.g., CURR? or TRIGline>). The message unit may include a data parameter after the keyword separated by a space;
the parameter is usually numeric (e.g., CURR 5), but may also be a string (e.g.,
OUTP ONne>). Figure 3-5 illustrates the message structure, showing how message units
are combined. The following subparagraphs explain each component of the message structure.
NOTE: An alternative to using the message structure for multiple messages defined in the fol-
lowing paragraphs is to send each command as a separate line. In this case each com-
mand must use the full syntax shown in Appendix B.
