16 :FUNCtion Commands
:FUNCtion:SOURce2
(see page 790)
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 specifies the second source for math
operations that have two sources (see the :FUNCtion:OPERation command),
in other words, ADD, SUBTract, or MULTiply. (The :FUNCtion:SOURce1
command specifies the first source.)
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.
The :FUNCtion:SOURce2 setting is not used when the :FUNCtion:OPERation
is FFT (Fast Fourier Transform).
Query Syntax
:FUNCtion:SOURce2?
The :FUNCtion:SOURce2? query returns the currently specified second
source for math operations.
Return Format
<value><NL>
<value> ::= {CHAN<n> | NONE}
<n> ::= {{1 | 2} | {3 | 4}} for 4ch models, depending on SOURce1
selection
<n> ::= {1 | 2} for 2ch models
