of parameter types you might see later in this chapter.
Table 5-1. SCPI Parameter Types
Parameter Type
Explanations and Examples
Numeric
Accepts all commonly used decimal representations of
numbers including optional signs, decimal points, and
scientific notation.
123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases include MIN, MAX, and INF.
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 TRIGger:SOURce <
where <
Optional Parameters. Parameters shown within square brackets (
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
ARM:COUNt? [<MIN | MAX>]
command without specifying a parameter, the present
returned. If you send the
minimum count available. If you send the
returns the maximum count available. Be sure to place a space between the
command and the parameter.
Linking IEEE 488.2 Common Commands with SCPI Commands. Use
a semicolon (;) between the commands. For example:
*RST;OUTP ON
Linking Multiple SCPI Commands. Use both a semicolon (
(
) between the commands. For example:
