4.5 Radiated Emissions
Radiated emission tests, such as described in EN 301 489-17, are designed to test that a DUTs unintentionally radiated
emissions are below defined limits. As the radio itself has been modularly certified this is not a test of the emissions with the
radio in operation. To prevent ETERNA2 from actively running it’s radio during connect to ETERNA2’s CLI port and enter
the set command as follows:
> radiotest on
Reset or power cycle ETERNA2. The radio is now inactive and will remain inactive until a tx or rx command is given.
After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s
normal state:
> radiotest off
Reset or power cycle ETERNA2.
4.6 Radiated Immunity
Radiated immunity tests, such as described in EN-61000-4-3, are designed to test a DUTs operation due to an out of band
interferer. When performing such tests the test system should be verified to prove the test system is not injecting noise due to
harmonic distortion into the 2.4 to 2.4835 GHz band. To perform this class of test ETERNA2 should be placed in a network
and the network function can be demonstrated as follows:
Create a network of devices with a network manager and two ETERNA2 motes (the minimum configuration to form a
network). Make sure the MAC addresses for both ETERNA2 motes and the manager are clearly labeled on each device.
Connect to the manager’s CLI port and issue the following commands:
> login user
> show mote *
