MATH[1]:DEFine
Sets or returns the current math function as a text string.
Dual math is defined 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 defined if the string is in the form
FFT(<wfm>), where <wfm> is any
live channel or reference waveform, and theMATH[1]:TYPe is FFT.
Advanced math is defined if the contents of the string can be parsed by the
advanced math pa rser 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.
