The measured RSSI in dbm is plotted on the graph as a function of time. On the right side
of the panel the numerical value of the RSSI is given in both a raw format and in the
calculated dBm units. The RSSI offset used for the calculation is also shown. The actual
RSSI offset is dependent on the connected device type and is found in the datasheet.
The RSSI value will be stored in an internal buffer of a fixed size and when the
maximum number of elements is reached, the next value will be stored from the
beginning again. It is a circular buffer of 5000 elements. That means it will only contain
measurements from the last 9 - 10 minutes. The exact number depends on the sample rate.
Theoretically this is every 100 ms, but due to the load of other tasks on the PC, this will
vary and be a bit higher.
Output signal
Depending on the connected device, the Continous RX mode will be configured to direct
the incoming RF signal to a connector on the given Evaluation Board.
