By configuring the different chart options, you can get a clear idea of the amount of data being transmitted,
received and the amount of other noise that can be heard at the radio. Configure what is to be logged on
each chart, select a time interval and save changes and the charts will then be displayed below the settings.
Click the button again to manually redraw the graphs. Each graph will display a percent channel utilization
using the selected criteria and time interval (seconds, minutes or hours).
Example 1
Chart one shows the amount of data that is being transmitted over a Wi-Fi link. Chart two shows the
amount of data being received from all sources (Wi-Fi and other noise). Notice that there is very little
outgoing data, but a constant stream of data is being received.

Example 2
In the second example (Figure 85), chart one shows the amount of data being received from Wi-Fi devices.
Chart two shows the amount of other noise that is being received. Notice that in the last 60-second period
there was a 20-second interval with around 60–80% channel utilization, in this case from a 2.4-GHz FHSS
telemetry device.
