:MATH:SOURce2
:MATH:SOURce2 <src>
:MATH:SOURce2?
Set or query source B of algebraic operation/the outer layer operation of compound
operation.
{CHANnel1|CHANnel2|CHANnel3|CHANnel4|FX}
 This command is only applicable to algebraic operations (requiring two sources) and
compound operations whose outer layer operations are algebraic operations.
 When the outlayer operation of compound operation is algebraic operation, this
command is used to set source B of the outer layer operation.
Note: When the outer layer operation of compound operation is algebraic operation, at least
one of source A and source B of the outer layer operation should be set to FX.
 When "FX" is selected, you can send
the :MATH:OPTion:FX:SOURce1, :MATH:OPTion:FX:SOURce2,
and :MATH:OPTion:FX:OPERator commands to set the sources and operator of the
inner layer operation.
The query returns CHAN1, CHAN2, CHAN3, CHAN4, or FX.
:MATH:SOURce2 CHANnel3 /*Set source B of algebraic operation to CH3*/
:MATH:SOURce2? /*The query returns CHAN3*/
:MATH:LSOUrce1
:MATH:LSOUrce1 <src>
:MATH:LSOUrce1?
Set or query source A of logic operation.
{D0|D1|D2|D3|D4|D5|D6|D7|D8|
D9|D10|D11|D12|D13|D14|D15|
CHANnel1|CHANnel2|CHANnel3|CHANnel4}
The logic operations include A&&B, A||B, A^B, and !A.
The query returns D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14,
D15, CHAN1, CHAN2, CHAN3, or CHAN4.
:MATH:LSOUrce1 D3 /*Set source A of logic operation to D3*/
:MATH:LSOUrce1? /*The query returns D3*/
