PicoScope 4444 differential oscilloscope
Math channels
With PicoScope 6 you can perform a variety of mathematical calculations on your input signals and reference waveforms.
Use the built-in list for simple functions such as add and invert, or open the wizard and create complex functions involving
trigonometry, exponentials, logarithms, statistics, integrals and derivatives.
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, it is being used to plot the frequency of
the top waveform, revealing that it is exponentially
modulated. Adding time and signal rulers allows
measurement of the period and range of this
modulation
You can also use the duty function to plot duty
cycle in a similar way.
