enum
CHANnel<n> ADD SUBTract MULTiply
Selects the source for function operations. Choose CHANnel<n>, or ADD, SUBT, or MULT to specify the desired source for FFT operations specified by the :FUNCtion:OPERation command.

# analog channels
Channel number in NR1 format
The :FUNCtion:SOURce command is only used when an FFT (Fast Fourier Transform) 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.
