Math channels and filters On many oscilloscopes waveform math just means simple calculations such as A + B. With a PicoScope it means much, much more. With PicoScope software you can select simple functions such as addition and inversion, or open the equation editor to create complex functions involving filters (lowpass, highpass, bandpass and bandstop filters), trigonometry, exponentials, logarithms, statistics, integrals and derivatives. Waveform math also allows you to plot live signals alongside historic peak, averaged or filtered waveforms. You can also use math channels to reveal new details in complex signals. An example would be to graph the changing duty cycle or frequency of your signal over time. More information on Math channels >>
