(see page 782)
Command Syntax
:FUNCtion:SOURce1 <value>
<value> ::= {CHANnel<n> | GOFT}
<n> ::= 1 to (# analog channels) in NR1 format
The :FUNCtion:SOURce1 command is used for any :FUNCtion:OPERation selection
(including the ADD, SUBTract, or MULTiply channel math operations and the FFT
transform). 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 function. 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

The :FUNCtion:SOURce1? query returns the current source1 for function
operations.
Return Format
<value><NL>
