Command Parameters
The following table contains explanations and examples of parameter types you
might see later in this chapter.
Parameter Type
Numeric
Accepts all commonly used decimal representations of number
including optional signs; decimal points; and scientific notation.
123; 123E2; -123; -1.23E2; .123; 1.23E-2; 1.23000E-01.
Special cases include MINimum; MAXimum; and DEFault.
Boolean
Represents a single binary condition that is either true or false.
ON; OFF; 1; 0
Discrete
Selects from a finite number of values. These parameters use
mnemonics to represent each valid setting. An example is the
SYSTem:SERial1:CONTrol:DTR <mode> where <mode> can be either
ON, OFF, STAN, or IBF
Optional Parameters. Parameters shown within square brackets ([ ]) are optional
parameters. (Note that the brackets are not part of the command and are not sent to
the instrument.) If you do not specify a value for an optional parameter, the
instrument chooses a default value. For example, consider the
command. If you send the command without specifying a parameter, the default
serial port (port 1) is used.
Linking Commands
Linking IEEE 488.2 Common Commands with SCPI Commands. Use a
semicolon between the commands. For example:
*RST;SYSTem:ERR?
Linking Multiple SCPI Commands. Use both a semicolon and a colon between
the commands. For example:
DIAG:LINE 1;:DIAG:LINE?
