SCPI Command Parameters

Parameter Types,

Explanations, and

Examples

The following information contains explanations and examples of the parameter types found in this chapter.

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 INFinity. The Comments section within the Command Reference will state whether a numeric parameter can also be specified in hex, octal, and/or binary:

#H7B, #Q173, #B1111011

Boolean

Represents a single binary condition that is either true or false. Any non-zero value is considered true:

ON, OFF, 1, 0

Discrete

Selects from a finite number of values. These parameters use mnemonics to represent each valid setting.

Arbitrary Block Program Data

This parameter type is used to transfer a block of data in the form of bytes. The block of data bytes is preceded by a header which indicates either 1) the number of data bytes which follow (definite length block), or 2) that the following data block will be terminated upon receipt of a New Line message with the EOI signal true (indefinite length block). The syntax for data in the blocks is as follows:

Definite length block:

#<non-zero digit><digit(s)><data byte(s)>

Where the value of <non-zero digit> equals the number of <digit(s)>. The value of <digit(s)> taken as a decimal integer indicates the number of <data byte(s)> in the block.
