SCPI Command Terminators
A command string sent to the instrument must terminate with a <new line>
(<NL>) character. The IEEE-488 End-Of-Identify (EOI) message is interpreted as a
<NL> character and can be used to terminate a command string in place of a
<NL> character. A <carriage return> followed by a <NL> is also accepted.
Command string termination will always reset the current SCPI command path to
the root level.
IEEE-488.2 Common Commands
The IEEE-488.2 standard defines a set of common commands that perform
functions such as reset, self-test, and status operation. Common commands
always begin with an asterisk ( * ), are three 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.
