previous command in the message up to and including the last colon separator. An example of a message with two commands is:

OUTPut:STATe ON;PROTection:CLEar

which shows the use of the semicolon separating the two commands, and also illustrates the command path concept. Note that with the second command, the leading keyword OUTPut was omitted because after the OUTPut:STATe ON command, the path became defined as OUTPut, and thus the second command was interpreted as:

OUTPut:PROTection:CLEar

In fact, it would have been incorrect to include the OUTPut keyword in the second command, because the result after combining it with the command path would be:

OUTPut:OUTPut:PROTection:CLEar

which would result in a syntax error.

Commands from Different Subsystems

In order to combine commands from different subsystems, you need to be able to reset the command path to a null string within a message. Beginning the command with a colon (:), discards the previous path. For example, you could clear the output protection and check the status of the Operation Condition register in one message by using a root specifier as follows:

OUTPut:PROTection:CLEar;:STATus:OPERation:CONDition?

The following message shows how to combine commands from different subsystems as well as within the same subsystem.

VOLTage:LEVel 7.5;PROTection 10;:CURRent:LEVel 0.25

Note the use of the optional keyword LEVel to maintain the correct path within the subsystems, and the use of the root specifier (:) to move between subsystems.

Message Unit

The simplest SCPI command is a single message unit consisting of a keyword followed by a message terminator such as newline. The message unit may include a parameter after the keyword. The parameter can be numeric or a string.

ABORt<NL>

VOLTage 20<NL>

VOLTage:TRIGgered MINimum<NL>

Colons (:) separate higher-level keywords from lower-level keywords. Use a blank space to separate parameters from keywords. If a command requires more than one parameter, use commas to separate adjacent parameters.
