SCPI COMMAND REFERENCE

Introduction

This Sub-Section lists and describes the set of SCPI-compatible

remote commands used to operate the 301/302. To provide familiar

formatting for users who have previously used the SCPI reference

documentation, the command descriptions are dealt with in a similar

manner. In particular, each sub-system's documentation starts with a

short description, followed by a table showing the complete set of

commands in the sub-system; finally the effects of individual keywords

and parameters are described. Complete listing of all commands used

for programming the Model 301/302 is given in Table 4.1.

SCPI Syntax and

Styles

Where possible the syntax and styles used in this section follow those

defined by the SCPI consortium. The commands on the following

pages are broken into three columns; the KEYWORD, the

PARAMETER FORM, and any NOTES.

The KEYWORD column provides the name of the command. The

actual command consists of one or more keywords since SCPI

commands are based on a hierarchical structure, also known as the

tree system. Square brackets ( [ ] ) are used to enclose a keyword

that is optional when programming the command; that is, the 302 will

process the command to have the same effect whether the optional

node is omitted by the programmer or not. Letter case in tables is

used to differentiate between the accepted short form (upper case)

and the long form (upper and lower case).

The PARAMETER FORM column indicates the number and order of

parameter in a command and their legal value. Parameter types are

distinguished by enclosing the type in angle brackets ( < > ). If

parameter form is enclosed by square brackets ( [ ] ) these are then

optional (care must be taken to ensure that optional parameters are

consistent with the intention of the associated keywords). The vertical

bar ( | ) can be read as "or" and is used to separate alternative

parameter options.

Querying Parameter

Setting

Query the current value of most parameters by adding a question

mark ( ? ) to the command. For example, the following command sets

the output function to square:

SOUR:FUNC:SHAP SQR

Query the output function by executing:
