Abstract: PROBLEM TO BE SOLVED: To enable a user to directly operate spectral display on a display by a high-degree intuitive dialogue method in a user interface in a computerized spectrum analyzer. SOLUTION: An initial difference spectrum equal to a sample spectrum is displayed on a display 2, and a data point having a related frequency in the initial difference spectrum is selected on the display 2 by a relative pointing device, and this data point is moved by a measurable quantity on the display 2 by a relative graphical input device, and a digit moving piece is determined in response to this measurable quantity and a data point in a reference spectrum having the same related frequency, and respective data points are digitally moved in the reference spectrum by the digit moving piece, and a moving reference spectrum is formed, and a difference spectrum between the sample spectrum and a digit moving reference spectrum is determined, and at least a part of the difference spectrum is displayed on the display 2.
