Figure 54. Runtime Screen
In Figure 54, the runtime screen will summarize the current valid settings.
Notes:
1. TR = Trigger sent on P1.4.
2. MP = Missed packets
3. PER = Packet error rate
7.2.10. Results (PER Test)
7.2.10.1. PER Measurement
The result of PER measurement is shown on the LCD display. Connecting to the GPIO and the trigger the user can
see the following signals.
Figure 55.
In Figure 55, the top trace shows the trigger provided on P1.4 of the SDB, the middle trace shows the received
data and the bottom trace shows the transmitted data from the RF signal generator.
In the plot we can see the receiver is turned on before the packet arrived. Once the valid packet is received the
radio will return to tune mode. The radio will switch to receive mode prior to sending the next trigger. This is
repeated for the value set in “Max. Packets”.
7.2.10.2. 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.
