skrf.network.n_twoports_2_nport¶
- skrf.network.n_twoports_2_nport(ntwk_list, nports, offby=1, **kwargs)[source]¶
Builds a N-port Network from list of two-ports
This method was made to reconstruct a n-port network from 2-port subnetworks as measured by a 2-port VNA. So, for example, given a 3-port DUT, you might measure the set p12.s2p, p23.s2p, p13.s2p. From these measurements, you can construct p.s3p.
By default all entries of result.s are filled with 0’s, in case you dont fully specify the entire s-matrix of the resultant ntwk.
- Parameters
ntwk_list (list of
Network
objects) – the names must contain the port index, ie ‘p12’ or ‘p43’, ie. define the Network.name property of theNetwork
object.offby (int) – starting value for s-parameters indices. ie a value of 1, assumes that a s21 = ntwk.s[:,1,0]
*args – passed to
Network.__init__()
for the N-port**kwargs – passed to
Network.__init__()
for the N-portnports (int) –
- Returns
nport – result
- Return type
n-port
Network
