Abstract:
1. A measuring apparatus comprising: a user I/F section having an operating section and a display section; a measuring section that measures an object to be measured or a signal to be measured; and a display control section that displays a measured waveform, which is based on measured data acquired by the measuring section, on the display section and also displays a waveform marker, which is movable by a marker operation from the user I/F section, so as to overlap the measured waveform, wherein the display control section displays the measured waveform on two-dimensional coordinates, which have a first axis and a second axis perpendicular to the first axis, on the display section, the waveform marker is movable by the marker operation corresponding to a direction parallel to the first axis, and the display control section has a detecting section, which detects the marker operation corresponding to a direction parallel to the second axis, and changes either setting of the waveform marker or a display range of the measured waveform according to the detection result of the detecting section; wherein the display control section sets, in a waveform display region where the measured waveform of the display section is displayed, an index which specifies a movement variation in a distance or a speed of the waveform marker corresponding to an operation amount in the marker operation as a plurality of steps in order of size, detects that a certain specific step of the index has been designated by a marker operation of the user I/F section, detects the operation amount when the marker operation for moving the displayed waveform marker has been performed after the designation, and moves the waveform marker by the movement variation specified by the index of the specific step, wherein the marker operation is performed by moving an indicator on a screen of the display section, and the display control section includes: an index storage section that stores specified information which specifies the movement variation in the distance or the speed of the waveform marker by dividing the movement variation into the plurality of steps in order of size; an index display control section that sets the index on the display section so that each of the plurality of steps can be designated and detects that the certain specific step of the index has been designated by the indicator in the marker operation; an instructed amount detecting section that detects, as the operation amount, a movement amount of the indicator in the marker operation after detection of the specific step; and a marker generating section that generates the waveform marker, receives the operation amount output from the instructed amount detecting section, and moves the waveform marker by the movement variation based on the specified information, which corresponds to the specific step detected by the index display control section, by referring to the specified information of the index storage section.
