:FUNCtion:SOURce
(see page 1610)
Command Syntax
:FUNCtion:SOURce <value>
<value> ::= {CHANnel<n> | ADD | SUBTract | MULTiply}
<n> ::= 1 to (# analog channels) in NR1 format
The :FUNCtion:SOURce command is only used when an FFT (Fast Fourier
Transform), DIFF, or INT operation is selected (see the:FUNCtion:OPERation
command for more information about selecting an operation). The
:FUNCtion:SOURce command selects the source for function operations. Choose
CHANnel<n>, or ADD, SUBT, or MULT to specify the desired source for function
DIFF (differentiate), INTegrate, and FFT operations specified by the
:FUNCtion:OPERation command.
Query Syntax
:FUNCtion:SOURce?
The :FUNCtion:SOURce? query returns the current source for function operations.
Return Format
<value><NL>
<value> ::= {CHAN<n> | ADD | SUBT | MULT}
<n> ::= 1 to (# analog channels) in NR1 format

NOTE
The :FUNCtion:SOURce command is an obsolete command provided for compatibility to
previous oscilloscopes. Use the :FUNCtion:SOURce1 command (see page 498) instead.
