Introduction to the SCPI Language
78 E3632A User’s Guide
SCPI command terminators
A command string sent to the power supply must terminate
with a <new line> character. The IEEE- 488 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. The <new line> character has the
ASCII decimal code of 10.
IEEE-488.2 common commands
The IEEE- 488.2 standard defines a set of common
commands that perform functions like reset, self- test, and
status operations. Common commands always begin with an
asterisk (*), are four to five characters in length, and may
include one or more parameters. The command keyword is
separated from the first parameter by a blank space. Use a
semicolon (;) to separate multiple commands as shown
below:
*RST; *CLS; *ESE 32; *OPC?
SCPI parameter types
The SCPI language defines several different data formats to
be used in program messages and response messages.
Numeric parameters
Commands that require numeric parameters will accept all
commonly used decimal representations of numbers
including optional signs, decimal points, and scientific
notation. Special values for numeric parameters like
MINimum, MAXimum, and DEFault are also accepted.
