MATH[1]:DEFine
Sets or returns the current math function as a text string.
Dual math is dened if the string is of the form <wfm> <operation> <wfm>,
where the <wfm>s are any combination of live channels or reference waveforms,
<operation> is any of +, -, * or /, and the MATH[1]:TYPe is DUAL.
FFT math is dened if the string is in the form FFT(<wfm>), where <wfm> is any
live channel or reference waveform, and theMATH[1]:TYPeis FFT.
Advanced math is dened if the contents of the string can be parsed by the
advanced math parser without errors and the MATH[1]:TYPe is ADVanced.
On the front panel, the Dual Wfm Math, FFT and Advanced Math menus contain
controls that allow building equivalent math expressions to those described above.
