2. SmartRF04EB Overview 3. Plug EM into SmartRF04EB
Insert a CC1101EM (EM) with an antenna
into the SmartRF04EB (EB). The
connectors will only fit in one position, so
that the EM cannot be inserted the wrong
way.
Handle the EM with care. Observe
precautions for handling electrostatic
sensitive devices.
4a. Power: Battery
There are three different ways of applying
power to the EB:
The first method involves using a battery,
for instance a 9V battery (not included in
the kit) connected to the connector on the
bottom side of the board.
4b. Power: DC/External
The second method applies DC power
using the DC input jack (right in picture,
centre is +, sleeve is ground), or by
connecting a 4-10V voltage source
between the 4-10V and 0V terminals of the
power connector (left in picture). It is also
possible to connect a 3.3V voltage source
between the 3.3V and 0V terminals. The
on-board voltage regulators will be
bypassed if the 3.3V input terminal is used.
4c. Power: USB
The EB can also be powered from the USB
bus.
Note that if multiple power sources are
connected, the source with the highest
voltage will power the EB. This means that
you should disconnect any attached
battery when using a lab supply or USB
power; otherwise the battery will be
drained.
5. Set Power Switch
If a 3.3V source is used as described in 4b
above, the switch should be set to the
leftmost position. For all other cases, the
switch should be set to the rightmost
position. This switch can be used to turn off
the EB by switching it to the opposite
position of that used to turn it on.
6. Packet Error Rate Test
When power is applied to the board, the
PER test program will start. You should
see the text shown above on the LCD
display on both evaluation boards.
Press the button marked S1 (lower right
corner) to continue.
7. Set Frequency Band
Select the desired frequency band of
operation by using the joystick. The
frequency should match the evaluation
module and antenna you are using.
Note that the value shown in the display is
also the selected value. There is no need
to press a button to select or activate the
selection.

8. Set Network ID
Push the joystick down to display the
screen shown above. This lets you set the
ID of the node in case you need to run
several PER tests simultaneously and you
have multiple development kits. Leave this
set to 1 for now.
9. Packet Length
Push the joystick down to display the
screen shown above. This lets you set the
length of the packets to be transmitted.
The packet length will affect the measured
packet error rate. Push the joystick left or
right to select the packet length you want
to use.
10. number of Packets
Push the joystick down to display the
screen shown above. This lets you set the
number of packets to be transmitted. Set
this to the desired value using the joystick.
11. Select RF Settings
Push the joystick down to display the
screen shown above. This lets you select
preset RF configurations, including
modulation and data rate
Preset 0: GFSK, 1.2 kBaud
Preset 1: GFSK, 10 kBaud
Preset 2: GFSK, 38.4 kBaud
Preset 3: GFSK, 250 kBaud
12. Select Mode
Push the joystick down to display the
screen shown above. Use the joystick to
select master mode. The EB you have
configured now will be the master in the
PER test.
13. Configure 2nd EB
Perform steps 3 through 11 on the second
EB. Push the joystick down until you get
the display shown above. Leave this EB in
slave mode.
14. Start PER
Push the joystick down on both EBs, and
the screen shown above is displayed. Push
the joystick right on the slave EB first, and
then push the joystick right on the master
EB. The PER test will start when the two
nodes have successfully connected.
Note that the PER test uses 10 dBm as
default output power, so the EBs should be
placed at least 1m apart to avoid saturation
of the receiver.
15. Run PER Test
The uppermost line of the LCD will show
the PER for packets transmitted from the
slave to the master, while the second line
will show the PER for packets transmitted
from the master to the slave.
The PER test will end when the number of
packets you selected in step 10 is reached
or if 100 consecutive packets are lost.

SmartRF™Studio
1. Download and Install
Before connecting the EB to your
PC, download SmartRF™Studio
from www.ti.com/smartrfstudio.
Install the program and follow the
instructions in the wizard.
Connect the EB with a CC1101EM
to the PC using the USB cable and
install the USB driver as described
in the manual.
2. Launch SmartRF Studio
Launch SmartRF Studio and double
click on the highlighted CC1101 device
icon to get complete control of the
device from the PC.
3. Configure the Radio
You can now configure the radio, run tests, export
register settings and run link tests with another
CC1101 on a SmartRF04EB connected to the PC.
