Operation
Table 5: Touchscreen actions menu
Icon Menu item Description
Select Selects markers and adjusts their position.
Span Zoom Zooms the graph area about the selected point. Touch the graph display at a point
of interest and drag to increase or decrease the span about the point of interest.
Span Zoom adjusts the span control and can affect the acquisition bandwidth.
CF Pan Adjusts the Center Frequency according to horizontal movement.
Zoom Adjusts horizontal and vertical scale of the graph. The fi rst direction with
enough movement becomes the primary scale of adjustment. Adjustment in the
secondary direction does not occur until a threshold of 30 pixels of movement is
crossed.
Dragging to the left or down zooms out and displays a smaller waveform
(increases the scale value). Dragging to the right or up zooms in and displays a
larger waveform (decreases the scale value).
Pan Adjusts horizontal and vertical position of the waveform. The fi rst direction with
enough movement becomes the primary direction of movement. Movement in
the secondary direction does not occur until a threshold of 30 pixels of movement
is crossed.
—
Reset Scale Returns the horizontal and vertical scale and position settings to their default
values.
—
Marker to peak Moves the selected marker to the highest peak. If no marker is turned on, this
control automatically adds a marker.
—
Next Peak
Moves the selected marker to the next peak. Choices are Next left, Next right,
Next lower (absolute), and Next higher (absolute).
—
Add marker De fi nes a new marker located at the horizontal center of the graph.
—
Delete marker Removes the last added marker.
—
All markers off Removes all markers.
Trigger On This Positions the DPX Density measurement box at the click point, measures the
current signal density, sets up the DPX Density Trigger function based on the
measurement result, and starts acquisitions.
