3.2.2.4. Data Mode Tab
Data Mode tab may have one or more subtabs based on number of times the device go into Data Mode state during the Signal Tap capture in a finite amount of time. Each subtab displays the Ethernet IP link behavior during the occurrence of Data Mode. Each Data Mode occurrence is also prefixed with a number to distinguish between various Data Mode occurrences.
