With Quick Measurements you can instantly perform multiple measurements in a waveform by using the Middle Mouse Button. Click the middle button and move the mouse to display measurements from any position (including over markers) to another position. These measurements are unique to the signal type and whether the Signal Definition has plotting enabled. You can also measure the period between two edges across multiple signals.
A simple period measurement is always displayed above the waveform between the two points while performing the Quick Measurement. However, additional measurements will appear in a floating window that hovers near the mouse. To dismiss the Quick Measurement, simply click again using any mouse button or use the ESC Key.
Note: While performing a Quick Measurement, any Dynamic Measurement windows in the same link group will use the period measured as the time span.
Note: Using the Control Key will override Signal Edge Snapping while measuring. (also see Environment Settings: Waveform Views )
Measure across multiple signals
Quick Measurements will snap to a transition edge (when near) and remember the Signal of the starting and ending measurement point. The measurement is always displayed for the signal currently under the mouse. However, if the starting signal is different than the ending signal, an additional arrow is displayed in the starting signal at the starting point.
In the graphic above, we are measuring the time between the falling edge of ALE and the falling edge of OE. We started the Quick Measurement on ALE so an additional arrow is displayed on the edge we started with. Any measurements displayed in the floating window will be measured from the signal currently under the mouse (OE in the graphic above).
Example for Signals with Field and Frame data
Example for Signals with Plot Enabled
When a signal is in plotting mode, Quick Measurements will calculate using the Plot data between the two mouse points. If multiple plots are enabled for the signal, Quick Measurements will function on the selected plot. Pressing the Space Bar will toggle the plot selection and refresh the measurements without having to move the mouse.
