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, DBUS, 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. If you send the MAX parameter, the command returns the maximum count available. 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 BUS;*TRG

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

between the commands. For example:

ARM:COUN 1;:TRIG:SOUR EXT

SCPI Command Reference

This section describes the Standard Commands for Programmable Instruments (SCPI) commands for the multiplexer modules. Commands are listed alphabetically by subsystem and also within each subsystem.
