As part of firmware code initialization i have following functions I am using radio tool radio_modulated_tx_carrier_duty_cycle() function to generate radio waves for FCC testing.

Regulatory (e.g. FCC) testing is anyway usually performed with a device that only runs a test application, such as our <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf_radio_test_example.html?cp=5_1_4_6_29">radio test example</a> or <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_dtm_serial.html?cp=5_1_4_5">DTM example</a>, not the end application.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
