Using Multiple Commands
Program Messages
Program Messages are a combination of one or more properly formatted SCPI
Commands. Program messages always go from a computer to the instrument.
They are sent to the instrument over its GPIB or serial interface as a sequence of
ASCII data messages.
Program Message Syntax
Figure 3-10
Common Commands and Subsystem Commands in the same program message.
If you send more than one command in one message, you must separate adjacent
commands with a semicolon.
<new line> = ASCII character decimal 10
^END = EOI asserted concurrent with last byte
Figure 3-10
When using IEEE 488.2 Common Commands with SCPI Subsystem commands on
the same line, use a semicolon between adjacent commands. For example:
When multiple subsystem commands are sent in one program message, the first
command is always referenced to the root node. Subsequent commands,
separated by ";", are referenced to the same level as the preceding command if no
":" is present immediately after the command separator (the semicolon).
