skrf.networkSet.NetworkSet.uncertainty_ntwk_triplet

NetworkSet.uncertainty_ntwk_triplet(attribute, n_deviations=3)[source]

Return a 3-tuple of Network objects which contain the mean, upper_bound, and lower_bound for the given Network attribute.

Used to save and plot uncertainty information data.

Note that providing ‘s’ and ‘s_mag’ as attributes will provide different results. For those who want to directly find uncertainty on dB performance, use ‘s_mag’.

Parameters:

  • attribute (str) – Attribute to operate on.

  • n_deviations (int, optional) – Number of standard deviation. The default is 3.

Returns:

  • ntwk_mean (:class: ~skrf.network.Network) – Network of the averaged attribute

  • lower_bound (:class: ~skrf.network.Network) – Network of the lower bound of N*sigma deviation.

  • upper_bound (:class: ~skrf.network.Network) – Network of the upper bound of N*sigma deviation.

Return type:

(Network, Network, Network)

Example

>>> (ntwk_mean, ntwk_lb, ntwk_ub) = my_ntwk_set.uncertainty_ntwk_triplet('s')
>>> (ntwk_mean, ntwk_lb, ntwk_ub) = my_ntwk_set.uncertainty_ntwk_triplet('s_mag')
