Logical Highs are identified in Green and lows in Blue. Bright White edges inform the user to zoom in. Notice that the vertical transitions on the digital waveforms are normally white, but there may be some transitions that are bright white. When this occurs, the hardware has detected that there was more than one transition there. Use the Wave Inspector Pan and Zoom controls to zoom in on a bright white edge. Also use MagniVu for higher timing resolution view of the edges. For additional MagniVu information please read FAQ ID 5849 & 5851
