16 :FUNCtion Commands

:FUNCtion:SOURce1

(see page 1138)

Command Syntax

:FUNCtion:SOURce1 <value>

<value> ::= {CHANnel<n> | GOFT | BUS<m>}

<n>::={1|2|3|4}for4chmodels

<n> ::= {1 | 2} for 2ch models

<m> ::= {1 | 2}

The :FUNCtion:SOURce1 command is used for any :FUNCtion:OPERation

selection. This command selects the first source for the operator math

functions or the single source for the transform functions, filter functions,

or visualization functions.

The GOFT parameter is only available for the transform functions, filter

functions, and the magnify visualization function (see "Introduction to

:FUNCtion Commands" on page 326). The GOFT parameter lets you specify,

as the function input source, the addition, subtraction, or multiplication of

two channels. When GOFT is used, the g(t) source is specified by the

:FUNCtion:GOFT:OPERation, :FUNCtion:GOFT:SOURce1, and

:FUNCtion:GOFT:SOURce2 commands.

The BUS<m> parameter is available for the bus charting visualization

functions available with the DSOX3ADVMATH advanced math license.

Query Syntax

:FUNCtion:SOURce1?

The :FUNCtion:SOURce1? query returns the current source1 for function

operations.

Return Format

<value> ::= {CHAN<n> | GOFT | BUS<m>}

<n>::={1|2|3|4}for4chmodels

<n> ::= {1 | 2} for 2ch models

<m> ::= {1 | 2}
