Cursors on a Mathematical Result (+ - x) Waveform

Cursor measurements on, for example, an AxB waveform give a reading in Watts if input A
measures (milli)Volts and input B measures (milli)Amperes. For other cursor measurements on,
for example, a A+B, A-B or AxB waveform no reading will be available if the input A and input B
measurement unit are different.
