Relay Multiplexer Command Reference 61Chapter 3

Parameter Types The following table contains explanations and examples of parameter

types you may see in this chapter.

Discrete parameters selects from a finite number of

lues. These parameters use mnemonics to represent

each valid setting. An example is TRIGger:SOURce

<source>, where source can be BUS, EXTernal, HOLD,

IMMediate, ECLTrgn, or TTLTrgn.

Optional parameters are shown within square brackets

(

[]). 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 ARM:COUNt?[MIN|MAX]. If you

nd 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. 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;*RCL 1 or

CLOS (@101);*SAV 1.

Linking Multiple SCPI commands. Use both a semicolon (;) and a colon (:)

between the commands, such as CLOS (@101);:CLOS? (@101). SCPI

also allows several commands within the same subsystem to be linked

with a semicolon and colon, such as 

ROUT:CLOS (@101);:ROUT:CLOS? (@101).

SCPI Commands Reference

This section describes the Standard Commands for Programmable

Instruments (SCPI) for the Relay Multiplexer module. Commands are

listed alphabetically by subsystem and within each subsystem.

Type Explanations and Examples

Boolean

Boolean parameters represent a single binary condition

that is either true or false (ON, OFF, 1, 0). Any non-zero

value is considered true.

Discrete

Numeric

Numeric parameters are commonly used decimal

representations of numbers including optional signs,

decimal points, and scientific notation (for example, 123,

123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E- 01).

Special cases include MIN, MAX, DEFault, and INFinity.

Optional
