<p>PROBLEM TO BE SOLVED: To enable one part of spectral display to be shown on an enlarged scale.SOLUTION: A test measurement apparatus 500 comprises a bitmap processor 510 that generates a first bitmap image from input test signals, a user interface 502 for specifying one part of the first bitmap image and a second bitmap processor 550 so configured as to generate a second bitmap image from the specified part of the first bitmap image. The second bitmap image is an enlarged image of the specified part of the first bitmap image, and the first and second bitmap images are so corrected as to be consistent on a time scale.</p> |
