SCPI Command Parameters
Parameters are enclosed in greater than/less than symbols (< >) in the command
syntax and must always be separated from the keywords by a space. When more
than one parameter is allowed, the parameters are separated by a vertical line ( | ).
The following information contains explanations and examples 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 scientific notation:
123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases include MINimum, MAXimum, 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. An example is the
TRIGger[:STARt]:SOURce
<
source> command where source can be BUS, ECLTrg0, ECLTrg1, EXTernal,
HOLD
, INTernal[1], INTernal[2], or TTLTrg0 through TTLTrg1.
• 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).
