(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> ::= {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.
