The following illustration shows an example of the Data Analyzer output with no
traffic being passed on the serial network. With no transmitted data to display,
the Data Analyzer shows only the "_TT_" timing markers, called "Time Ticks".
The time between Time Ticks is adjustable and can be set in the Data Analyzer
Setup dialog box, as previously seen.
In this example the Time Ticks have been set to 50 milliseconds. During actual
transmission of data, the Time Ticks will appear interspersed within the data
bytes and indicate the configured time interval. This information can be valuable
for troubleshooting certain kinds of communication problems.
