Comparing channel measurement results between single tone excitation, simple multi tone excitation and realistic communicational multi tone excitation, the influence to uncertainty of channel measurement in frequency domain is experimentally investigated. Reverberation chamber is used for simulate the complicate wireless channel used in practical applications. Signal generator is connected to the vector network analyzer to improve the traditional measurement method in frequency domain to the complex excitation type. Measurements on a connector are arranged for the control group. The influence is analyzed by averages of repeated measurements, and discussed from the aspect of nonlinearity of wireless channel and theoretical measurement uncertainty.
