SCPI Command Parameters
The following information contains explanations and exa mples of the
parameter types found in this chapter.

Parameter Types,

Explanations, and

Examples

•Numeric
Accepts all commonly used decimal representations of numbers
including optional signs, decimal points, and sci e nti f ic notation:
123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases inc l u de MIN, MAX, and INFi n ity. The Comments
section within the Command Reference will state whether a nume ric
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 p arameters 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 wil l be te rminated
upon receipt of a New Line message with the EOI signal true
(indefinite length block). The syntax for data in the bl oc ks 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 <d i git(s)> taken as a decima l in te g er
indicates the number of <data byte(s)> in the block.
