In many instances the properties of a network are obstructed by an intervening network,
which is required when performing measurements of the network. These intervening
networks are often in the form of a mode transformer and are, in the general sense, referred
to as error networks.
A new analysis mechanism is developed by applying a de-embedding method that was
identified as being robust. The analysis was subsequently implemented in a numerical
computational software package. The analysis mechanism can then be applied to perform
the characterisation of error networks. The performance of the analysis mechanism is
verified using an ideal lumped-element network. The limitations of the mechanism are
identified and possible ways of addressing these limitations are given. The mechanism is
successfully applied to the characterisation of three different microwave networks.
