The invention discloses a nonlinear network phase calibration measurement device and a calibration measurement method, and belongs to the field of measurement. The device comprises a signal generating unit and a signal receiving unit, wherein the signal generation unit comprises a plurality of excitation sources and a plurality of source switches; the signal receiving unit comprises a receiver, a plurality of receiving switches and a plurality of local oscillation sources. According to the method, a comb generator does not need to be used when nonlinear network characteristics are tested, the problem that the output signal power is too small under the working conditions of small frequency interval and high frequency is effectively solved, and the excitation source used by the device can still guarantee enough output power under the high frequency; according to the device, any output frequency component of the output signal of the measured piece can be measured, and compared with the prior art, the applicabili
