Available Operations in Signal Integrity Viewer

You can use the Signal Integrity Viewer toolstrip operations to view and analyze waveforms. The available operations can be divided into these groups:

• Refresh

• Zoom

• Marker

• Threshold

• Display mode

• Miscellaneous

Refresh

Button	Operation	Description
	Reread data and refresh display	Reread data from files and redraw currently displayed waveforms.
	Refresh display	Redraw currently displayed waveforms.

Zoom

Button	Operation	Description
	Zoom fit	Fit waveforms to display area.
	Zoom fit vertical	Fit waveforms in the vertical dimension only.
	Zoom fit horizontal	Fit waveforms in the horizontal dimension only.
	Zoom points	Click and drag to draw a zoom area.
	Zoom min/max	Specify the coordinates of the zoom area. The minimum X and minimum Y points specify the lower left of the zoom area. The maximum X and maximum Y points specify the upper right of the zoom area.
	Zoom in	Increase the magnification of the display area.
	Zoom out	Decrease the magnification of the display area.
	Zoom horizontal	Click and drag to draw a horizontal zoom area.
	Zoom vertical	Click and drag to draw a vertical zoom area.
	Zoom previous	Set display to previous zoom state.

Marker

Button	Operation	Description
	Measure	Add a marker to the display to perform measurements. Markers can be single-point or two point. The placement of the markers can be constrained to the selected waveform and/or thresholds.
	Horizontal measure	Add a marker to the display to perform horizontal measurements.
	Vertical measure	Add a marker to the display to perform vertical measurements.
	Text box	Add a text box as marker label.

Threshold

Button	Operation	Description
	Horizontal threshold	Add a horizontal threshold to the display.
	Vertical threshold	Add a vertical threshold to the display.
	Rotated threshold	Add a rotated threshold to the display.

Display Mode

Button	Operation	Description
	Overlay mode	Overlay waveforms on the same y-axis. This is the default display mode.
	Eye mode	Display the current waveform as an eye diagram.
	Fourier transform mode	Display the Fourier transform of the displayed waveforms.
	Split view mode	Display each waveform on a separate y-axis.
	Polar view mode	Display compatible nodes on a polar chart.

Miscellaneous

Button	Operation	Description
	Delete	Delete the selected waveform(s).
	Display preferences	Launch the Display Preferences dialog box.
