V^2 - the result is the point-by-point product of the waveforms.
Restricted to Ext Trigger voltage waveforms.
Invalid – the combination of arguments and operator is invalid.
Some of the many valid combinations of arguments and operators provided by this function may
not be meaningful in any practical sense, or may require further interpretation to be meaningful.
The most useful are simple ratios, differences and sums. The combination of Channel Math with
Marker Math yields ratios of ratios, which are very difficult to interpret.
