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

Calculate 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.

  • 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.

  • squeeze (bool) – Squeeze step response to one dimension, if a oneport gets transformed. Has no effect when transforming a multiport. Default = True


  • t (class:np.ndarray) – Time vector

  • y (class:np.ndarray) – Step response

Return type:

tuple[ndarray, ndarray]
