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.
