7.2.8. Results (BER Test)
7.2.8.1. BER Sensitivity Evaluation
BER results will be shown on the BER instrument or recorded by either RF generators or IQ modulators that have
a BER option installed.
The top trace in Figure 48 demonstrates TX_Data as sent by a transmitter and the bottom trace is the data
received on the GPIO pin. Please note that there is an expected shift caused by a delay between the data at the
transmitter and the data received by the receiver.

7.2.8.2. Other Receiver Measurements
Using the test setup described above, users may also perform Automatic Frequency Control (AFC), Blocking and
Selectivity tests. All the required parameters are controlled by the external RF generator.
