SCPI Command Terminators
A command string sent to the U2741A 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?
Using the MIN, MAX, and AUTO Parameters
You can substitute
MINimum, MAXimum
, or
AUTOmatic
in place of a parameter for
many commands. For example, consider the following command:
SENS:VOLT:DC:RANG [<range|MINimum|MAXimum|AUTOmatic>]
Instead of selecting a specific voltage range, you can substitute
MIN
to set the range to its minimum value,
MAX
to set the range to its
maximum value, or
AUTO
to set it to automatic.
