Annotation: In the paper we propose the method of recording of object responses which increase the sensitivity of ultra wideband nonlinear network analyzer. The results of experiments on the detection of nonlinear object which have small nonlinear properties are given. Experimental investigations were performed using the PXI hardware platform.

Keywords: nonlinear reflectometry, defective contacts, nonlinearity characteristic, signal-to-noise ratio
