Abstract:
1. A method of equalization of a vector/signal analyzer, the vector signal/analyzer including a linear filter in a signal path between an input terminal and an output terminal, wherein the linear filter is responsive to applied coefficients to correct frequency distortion, comprising: (a) providing a structured test signal within a selected frequency range, the structured test signal comprising a plurality of frequency components each having a respective amplitude and phase; (b) inputting the test signal to the analyzer; the analyzer operating to condition the test signal; (c) determining information representative of frequency distortion of the conditioned test signal introduced by the analyzer; (d) generating a set of equalization coefficients based on the information representative of the frequency distortion, the set of coefficients corresponding to the selected frequency range; (e) storing the set of equalization coefficients and the correspondence of the set of coefficients to the selected frequency range; and (f) applying the stored coefficients to the linear filter;
