Section 6: Introduction to SCPI commands
SCPI parameters
The parameters of the SCPI commands are shown in angle brackets (< >). For example:
:SYSTem:BEEPer:ERRor:STATe <state>
The type of information that you can use to replace <state> is defined in the Usage section of the
command description. For this example, the usage is:
<state>
For this example, you can enable the beeper by sending:
:SYSTem:BEEPer:ERRor:STATe ON
Note that you do not include the angle brackets when sending the command.
Sending strings
If you are sending a string, it must begin and end with matching quotes (either single quotes or
double quotes). If you want to include a quote character as part of the string, type it twice with no
characters in between.
A command string sent to the instrument must terminate with a <new line> character. The
IEEE-488.2 EOI (end-or-identify) message is interpreted as a <new line> character and can be used
to terminate a command string in place of a <new line> character. A <carriage return> followed
by a <new line> is also accepted. Command string termination will always reset the current SCPI
command path to the root level.
