User's Manual

10. Select Frequency
Select which frequency to use for the test. Make
sure that the evaluation modules you have match
the selected frequency.
11. Select Mode
One of the boards must operate as the slave
(transmitter) and the other as master (receiver).
Select Slave on one board…
…and Master on the other board.
12. Establish Link
The slave node will now wait for a configuration
package from the Master. The configuration
contains the parameters used for the PER test.
The configuration package will be sent when you
select “link devices” on the master node.
13. Link Established
When the initial linking has completed, the slave
node will start the test by continuously transmitting
packets to the master.
14. Start the Receiver (master)
On the master node, you can select the number of
packets you want to receive in order to calculate
the packet error.
When selecting “Start PER Test”, the master
(receiver) will begin to count the number of
received packets and provide some statistics.
15. PER Test Results
The master will display a window that plots the
received signal strength (RSSI) for each packet.
Press the “Up” button to go to the detailed
statistical window.
16. PER Test Results
The statistics window will show the error rate
based on the number of lost or erroneous packets
divided by the total number of packets that should
have been received.
17. Troubleshooting
It you are experiencing problems with this test,
please check the following:
 Nothing is shown in the display! Make sure the
mode switches are in the correct positions (see
step 4 above).
 Please visit the kit web page and check for
updated SW and documentation. Updated SW
can be downloaded to the device using IAR
EW430 or SmartRF Flash Programmer.
 If you get poor PER results at short distances,
try to move the transmitter and receiver further
apart. The CC11xL receiver may experience
saturation if it is too close to the other CC11xL
transmitting at full output power.
