A measuring section measures a digital multiplex signal divided into slot units, as a signal to be measured. A display control section displays, on a screen, a measured waveform of the signal. An analyzing section analyzes, in the slot units, information relating to the measured waveform of the signal. A storage section stores the information relating to the measured waveform of the signal which is analyzed in the slot units, as analyzed information of the slot unit. A marker display control section displays a slot marker to designate an arbitrary slot, in correspondence with the measured waveform of the signal which is displayed on the screen. A slot information display control section reads, from the storage section, the analyzed information of the slot unit corresponding to the slot designated by the slot marker displayed on the screen, and displays the analyzed information of the slot unit in correspondence with the slot marker.

Method for analyzing signal and signal analyzer having function for displaying slot information

A storage stores data of plural function menus corresponding to plural function menu items composed of plural pages to be used in instruction of execution of mutually different plural functions to process tested data of an object displayed in a first region on a screen of a display section. A screen manager selectively reads out function menu data of one page corresponding to a specified function from data of plural function menus stored in the storage, in accordance with setting of a display state displayed on the screen, and displays in a second region different from the first region, corresponding to each of the plural function keys. A list display section reads out data of plural function menus of all pages corresponding to the specified function from data of plural function menus stored in the storage, depending on the operation of a list display key, and displays a list in a third region, different from the second region, including the first region.
