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.
