Integral (Step response)

 

Integrates the measurement data. This is useful for example if you are measuring velocity but want to display displacement. If the measurement is an impulse response, the result is a step response. This is because the integral of an impulse response is a step response.

When performing integration, the DC-component should be removed, so make sure is checked.

Instead of using this integration option, you may use the plot type named Integrated Time Data (Step Response).

The numerical integration is performed by cumulative summing of the elements. This gives a time shift error of one half sample which gives a linear phase shift. No correction for this is performed, but it may be done using the Subtract delay check box in the phase response/function plot type settings.
