https://devzone.nordicsemi.com/f/nordic-q-a/16727/ce-r-tte-testing-of-different-packet-types-with-nrf52Hi All, we currently move our custom design to CE testing and already did some successful EMC pretesting. However, our testing house asked us to prepare a firmware for fixed frequency testing with different packet types (DH1,DH3,DH5).

I will adjust the radio test example.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63976?ContentTypeID=1Fri, 30 Sep 2016 06:51:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:31714791-7c9d-462a-8069-6aef9858bb7dFormerMember<p>For testing the radio against regulatory standards, FCC, ETSI, etc, I would recommend you to use the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v12.0.0%2Fnrf_radio_test_example.html&amp;cp=4_0_0_4_5_23">radio test example</a> in the SDK. It allows you to control the radio over UART. With the radio test example, you can set it in TX to a fixed frequency, and measure the harmonics (conducted or radiated). Setting the radio in RX enable you to measure the RX LO.</p> <p>For Bluetooth Low Energy (BLE) testing, DTM should be used. DH1, DH3, and DH5 are packet types used in Bluetooth BR/EDR (Bluetooth 1.1/2.0). I would recommend you to check with the test house that they plan to do the correct testing, either for testing for regulatory standards or for BLE.</p><div style="clear:both;"></div>
