Math operations

The Math operations can add, subtract, multiply or perform FFT/FFT
RMS on the input waveforms. The resulted waveform can be measured using
the cursors, and saved or recalled just like normal input signals.

Voltage level of the upper cursor.
Voltage level of the lower cursor.
The difference between the upper and lower
cursor.
The voltage / current difference (Y1-Y2).
Adds amplitude of CH1 & CH2 signals.
Extracts the amplitude difference between CH1
& CH2.
Multiplies CH1 and CH2 (OD-411, OD-415
only).
Performs FFT calculation on a signal. Four
types of FFT windows are available: Hanning,
Flattop, Rectangular, and Blackman.
