Parameters Parameter Types. The following table contains explanations and examples of parameter types you might see later in this chapter.

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 DEF. MIN selects

 

minimum value available, MAX selects maximum value

 

available, and DEF selects default or reset value.

 

 

Boolean

Represents a single binary condition that is either true or

 

false.

 

1 or ON; 0 or OFF.

 

 

Discrete

Selects from a finite number of values. These parameters

 

use mnemonics to represent each valid setting.

 

An example is the TRIGger:SOURce <source> command

 

where source can be BUS, EXT, HOLD, or IMM.

 

 

 

 

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 ARM:COUNt? [<MIN MAX>] command. If you send the command without specifying a parameter, the present ARM:COUNt value is returned. If you send the MIN parameter, the command returns the minimum count available (1). If you send the MAX parameter, the command returns the maximum count available (32,767). Be sure to place a space between the command and the parameter.

Linking Commands Linking IEEE 488.2 Common Commands with SCPI Commands. Use

a semicolon between the commands. For example:

*RST;OUTP ON

or

TRIG:SOUR HOLD;*TRG

Linking Multiple SCPI Commands. Use both a semicolon and a colon

between the commands. For example:

ARM COUN 1;:TRIG:SOUR EXT

SCPI allows several commands within the same subsystem to be linked with a semicolon. For example:

ROUT:CLOS (@100);:ROUT:OPEN (A101)

or

ROUT:CLOS (@100);OPEN (@101)
