skrf.network.Network.step_response¶

Network.step_response(window='hamming', n=None, pad=1000)[source]¶

Calculates time-domain step response of one-port.

First frequency must be 0 Hz for the transformation to be accurate and the frequency step must be uniform.

Real measurements should be extrapolated to DC and interpolated to uniform frequency spacing.

Y-axis is the reflection coefficient.

Parameters:

window (string) – FFT windowing function.
n (int) – Length of step response output. If n is not specified, 2 * (m - 1) points are used, where m = len(self) + pad
pad (int) – Number of zeros to add as padding for FFT. Adding more zeros improves accuracy of peaks.

Returns:
