Abstract
The invention relates to a multi-carrier method in a measurement device for improving reach of a measurement, said method comprising: transmitting a first signal in a sequence, measuring a response to said first signal, calculating a first transfer function for frequency of each modulated subcarrier in the first signal, transmitting a second signal of the sequence, wherein at least one subcarrier in the second signal has modulation different from that of the subcarriers in the first signal, measuring a response to said second signal, calculating a second transfer function for frequency of each modulated subcarrier in the second signal, said second transfer function comprising for each frequency a thereto associated second distortion component, calculating a mean value of all first and second transfer functions. The invention further relates to a measurement device for performing said method.
