The present invention discloses a harmonic rejection load pull tuner. The tuner of the invention has a large-band tuner having an input and an output, and a transmission line having a longitudinal axis. The transmission line has an input connected to the output of a DUT and an output connected to the input of the large-band tuner. In parallel with the transmission line is at least one stub, the at least one stub having a length adapted to reflect out an nth order harmonic of a base frequency, where n is an integer greater than 1. The tuner of the present invention can be used to perform input or output characterisation (or both) of a DUT, by selectively reflecting out at least one harmonic frequency of the base frequency. Consequently, the characterisation of the DUT is improved, since the effects of the harmonics are considerably reduced. The present invention also concerns a method for performing input or output characterisation.
