PicoScope 2000 Series oscilloscopes

Math channels and filters

With PicoScope 6 you can perform a variety of mathematical calculations on your input

signals and reference waveforms. 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.

Display up to eight real or calculated channels in each scope view. If you run out of

space, just open another scope view and add more. You can also use math channels to

reveal new details in complex signals, for example graphing the changing duty cycle or

frequency of your signal over time.

Plot frequency against time with PicoScope 6

All oscilloscopes can measure the frequency of a

waveform, but often you need to know how that

frequency changes over time, which is a difficult

measurement to make. The freq math function can

do exactly this: in this example, the top waveform’s

frequency is being modulated by a ramp function, as

plotted in the bottom waveform.

A separate math function allows you to plot duty cycle

in a similar way.
