5 Commands by Subsystem

:FUNCtion:SOURce2

(see page 658)

Command Syntax

:FUNCtion:SOURce2 <value>

<value> ::= {CHANnel<n> | NONE}

<n> ::= {{1 | 2} | {3 | 4}} for 4ch models, depending on SOURce1

selection

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

The :FUNCtion:SOURce2 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:SOURce2 command selects the source for

function operations. Choose CHANnel<n>, or ADD, SUBT, or MULT to

specify the desired source for function DIFFerentiate, INTegrate, and FFT

operations specified by the :FUNCtion:OPERation command.

If CHANnel1 or CHANnel2 is selected for :FUNCtion:SOURce1, the

SOURce2 selection can be CHANnel1 or CHANnel2. Likewise, if CHANnel3

or CHANnel4 is selected for :FUNCtion:SOURce1, the SOURce2 selection

can be CHANnel3 or CHANnel4.

Query Syntax

:FUNCtion:SOURce2?

The :FUNCtion:SOURce2? query returns the second source for function

operations on two waveforms.

Return Format

<value> ::= {CHAN<n> | NONE}

<n> ::= {{1 | 2} | {3 | 4}} for 4ch models, depending on SOURce1

selection

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