eZ-Analyst vibration analysis software now includes a 3-D Color Waterfall Display to augment the spectrum display capabilities. Each spectrum window added to the display screen can have its own 3-D waterfall with unique configuration settings. These displays include latitude and longitudinal display rotations; up to six user-definable waterfall perspective presets; a 3-D plot cursor to display the value at a specific X, Y and Z plot coordinates; automatic tracking of scale and axis changes; and a configurable number of spectrum records. In addition, a 2-D Frequency Slice display has been added to the analysis toolbox. With its flexible display configuration capability, users can view the 3-D waterfall as well as 2-D Frequency Slice displays in the same or individual spectrum windows.
