https://devzone.nordicsemi.com/f/nordic-q-a/65916/nordic-recommended-test-for-latent-failureHello, Is there a particular test Nordic recommends to screen for latent failures in the BLE circuit? If one has access to an Anritsu MT8852B tester with Direct-Test-Mode, can one of the tests be used to accomplish this type of test?

If you do a radiated test in a fixture, you will test the antenna as well. So such a test will test most of the functionality of the device.&nbsp;</p><div style="clear:both;"></div>
