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.
*RST; *CLS; *ESE 32; *OPC?
Channel List Parameters
The channel parameter is required to address one or more channels.
It has the following syntax.
(@<ch_list> [,<ch_list>][,<ch_list>])
You can also specify a range of sequential channels as follows.
(@<start_ch_list>:<end_ch_list>)
The following command closes channel 101 on the module.
ROUT:CLOS (@101) // For single channel selection.
