15 :FUNCtion Commands
:FUNCtion:SOURce1
(see page 860)
Command Syntax
:FUNCtion:SOURce1 <value>
<value> ::= {CHANnel<n> | GOFT}
<n>::={1|2|3|4}for4chmodels
<n> ::= {1 | 2} for 2ch models
The :FUNCtion:SOURce1 command is used for any :FUNCtion:OPERation
selection (including the ADD, SUBTract, or MULTiply channel math
operations and the FFT, INTegrate, DIFF (differentiate), or SQRT
transforms). This command selects the first source for channel math
operations or the single source for the transforms.
The GOFT parameter is only available for the FFT, INTegrate, DIFF
(differentiate), or SQRT functions. It 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.
Query Syntax
:FUNCtion:SOURce1?
The :FUNCtion:SOURce1? query returns the current source1 for function
operations.
Return Format
<value><NL>
<value> ::= {CHAN<n> | GOFT}
