摘要：

In this paper a method is proposed to compensate for the nonlinear distortions present in the input signal of a DUT which results in a source-pull free level of the output nonlinear distortions. This allows to determine an accurate adjacent co-channel power ratio (ACPR). The proposed measurement technique is based on a vector network analyzer (PNA-X) and uses a broadband multisine excitation. Results obtained from a microwave amplifier are reported.
