It is shown in this paper how the classical concept of the "network analyser" can be extended towards modulated and large-signal operating conditions. The concept is demonstrated by measuring the saturated behaviour of a MMIC amplifier, excited by modulated signals with CDMA characteristics. It is then illustrated how the measured data can be used to construct an accurate behavioural model.
