skrf.networkSet.NetworkSet

class skrf.networkSet.NetworkSet(ntwk_set, name=None)

A set of Networks.

This class allows functions on sets of Networks, such as mean or standard deviation, to be calculated conveniently. The results are returned in Network objects, so that they may be plotted and saved in like Network objects.

This class also provides methods which can be used to plot uncertainty bounds for a set of Network.

The names of the NetworkSet properties are generated dynamically upon ititialization, and thus documentation for individual properties and methods is not available. However, the properties do follow the convention:

>>> my_network_set.function_name_network_property_name

For example, the complex average (mean) Network for a NetworkSet is:

>>> my_network_set.mean_s

This accesses the property ‘s’, for each element in the set, and then calculates the ‘mean’ of the resultant set. The order of operations is important.

Results are returned as Network objects, so they may be plotted or saved in the same way as for Network objects:

>>> my_network_set.mean_s.plot_s_mag()
>>> my_network_set.mean_s.write_touchstone('mean_response')

If you are calculating functions that return scalar variables, then the result is accessable through the Network property .s_re. For example:

>>> std_s_deg = my_network_set.std_s_deg

This result would be plotted by:

>>> std_s_deg.plot_s_re()

The operators, properties, and methods of NetworkSet object are dynamically generated by private methods

• __add_a_operator()
• __add_a_func_on_property()
• __add_a_element_wise_method()
• __add_a_plot_uncertainty()

thus, documentation on the individual methods and properties are not available.
