("?") to the command. For example, the following command sets the output
frequency to 5 kHz:
You can then query the frequency value by executing:
You can also query the minimum or maximum frequency allowed with the present

SCPI Command Terminators
A command string sent to the function generator 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 IEEE-488.2 standard defines a set of common commands that perform
functions such as reset, self-test, and status operations. Common commands
always begin with an asterisk (
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:
