It contains an Excel file, which is described below:The phase and amplitude modulation measurement based on fiber structure for sensitivity beyond the SNL are studied in the article, including measured noise power of the quadrature-phase and quadrature-amplitude squeezed vacuum states; the phase modulation measurements; the amplitude modulation measurements; the shot noise reduction for measured amplitude modulation. The data were obtained by spectrum analyzer and drawn by Oringin. squeezed vacuum states; fiber Mach-Zehnder interferometer; optical precision measurement Guohui Kang Jinxia Feng Lin Cheng Yuanji Li Kuanshou Zhang PUBLIC https://creativecommons.org/licenses/by-nc-sa/4.0/ dataset http://www.doi.org/10.1088/1674-1056/acc520 Science Data Bank
