Math Channels
A math channel is a virtual channel generated by a mathematical function of the input
channel. It can be displayed in an oscilloscope in the same way as an input signal,
and like an input signal it has its own measure axis, scale and color.
The oscilloscope has a set of built-in math channels for the most important functions:
 Turnover: reverses the signal polarity to turn the waveform upside down on
the screen
 A+B: channel A plus channel B
 A-B: channel A minus channel B
 A*B: multiply channel A by channel B
 A/B: channel A divided by channel B
 Frequency: the frequency of the signal
 Pulse Width (+): the positive pulse width
 Pulse Width (-): the negative pulse width
 Duty Cycle (+): the positive duty cycle
 Duty Cycle (-): the negative duty cycle
NOTE
When connecting via Wi-Fi, it only supports Turnover, A+B, A-B, A*B and A/B.
