10. Modulation Setup
There are 6 different modulation schemes
available for this application. The different
bitrates are 250 Kbps, 500 Kbps, 1Mbps and 2
Mbps. MSK modulation is used for the 500 Kbps
rate and GFSK for the rest. Move the joystick up
or down to change the scheme and press S1 to
confirm the choice.
11. Packet Length
The packet length can be set to 10, 16, 32, 64 or
120 bytes. Move the joystick up or down to
change the packet length and press S1 to
confirm the choice.
12. Number of Packets
The total number of packets to be sent for each
run can be set to 200, 1000, 5000, 10000 and .
Move the joystick up or down to change the
number of packets and press S1 to confirm the
choice.
13. Test Running
The remote device acknowledges the beacon
signal from the master and sends the
configuration packet. The PER test begins. While
the master device is sending packets the yellow
led will be lit on the smartRF05EB (“LED3”) or
the red led on the CC2544 Dongle (“LED1”).
14. PER Test Summary
The first results screen will display the number of
packets received without errors (“Good”), the
number that were received with a CRC error
(“Bad”), and the number that were expected but
not received (“LOST”). Push button S1 to
proceed to the second results screen.
15. Repeat Test
The final screen allows the test to be repeated by
pushing “Button 1” (S1). Note that the set up data
is maintained. If you wish to enter different test
parameters, you may do so by pushing “EM
RESET” button, located at the approximate
center of the SmartRF05EB.
