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 6 you can select simple functions such as addition and inversion, or open the equation editor to create complex functions involving filters (low pass, high pass, band pass and band stop 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 for example to graph the changing duty cycle or frequency of your signal.
