Abstract:
1. A multi-carrier method in a measurement device for improving reach of a measurement, said method comprising: transmitting a first signal in a sequence, said first signal having at least two first modulated subcarriers associated thereto, measuring a response to said first signal, calculating a first transfer function for frequency of each modulated subcarrier in the first signal, said first transfer function comprising for each frequency a thereto associated first distortion component, transmitting a second signal of the sequence, said second signal having at least two second modulated subcarriers associated thereto, wherein a subcarrier modulation of at least one subcarrier in the second signal is different from a subcarrier modulation of the corresponding subcarrier 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, wherein an aggregate of all first and second distortion components comprises at least one distortion component having a sign that differs from the sign of the remaining distortion components constituting said aggregate, calculating a mean value of all first and second transfer functions.
