7.5.3 Markers
Markers are used to select the waveform range in the horizontal direction when editing or creating any
type of the waveform. They are also used to specify the horizontal position in order to read the vertical
value of the waveform.
Markers are displayed with red and blue vertical lines in the waveform display area.
Markers operation
Two types of markers are used in the Arbitrary waveform editing tool: A marker (red) and B marker (blue).
A marker cannot be located on the right side of B marker. A marker is always located on the left side or
same position of B marker. The position of each marker is displayed in the [X] field corresponding to
the [Marker:] field of each color. The value of the waveform corresponding to the marker position is
displayed in the [Y] field.
Moving markers (mouse dragging)
Two methods are provided in order to move markers: dragging a mouse and specifying values.
When the mouse cursor is hovered over a marker, the shape of the cursor is turned into from .
To move the marker, drag the mouse while the cursor is in this shape. Although the markers on any end
of the line can be difficult to identify, they can also be moved by using the maker flag located in the
upper part of the waveform display area.
When moving markers by dragging a mouse, the address of the waveform data is moved as a unit of
movement. Under the display magnification in which multiple addresses are mapped to one dot, the
movement occurs by a step of that number of addresses corresponding to one dot.
Moving markers (specifying values)
To specify the marker location with higher resolution, enter values for the marker location directly.
The location display section for A marker is selected by clicking the [X] item corresponding to it or
pressing the Alt key and A key. Enter values and press the Tab key to move A marker to the specified
location.
To specify the marker location with higher resolution, enter values for the marker location directly.
B marker is also moved to the specified location by clicking the [X] item corresponding to B marker or
pressing the Alt key and B key, entering values for B maker in the location display section, and pressing
the Tab key.
The marker can be located in any location within the range of the settings/display resolution regardless
of addresses of the waveform data by specifying values.
Coordinate marker mode
A and B markers can be moved independently or together depending on the Link check box.
When the Link check box is selected, A and B markers are moved together. The gap in the horizontal
direction between A and B markers (distance between markers) is displayed on the right of [dX(-)].
When moving one of these markers, the other one is also moved keeping the distance.
When you click the right side of the [dX(-)] or press the Alt key and the - key, enter values, and press
the Tab key, B marker is moved so that the gap between markers is set to the specified value.
Range of impact by markers
Selecting the range by using markers affects the operations below.
