CE R&TTE testing of different packet types with nRF52

Philipp Mahr

Hi 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).

Looking into radio test example and DTM I couldn't find a way to set these. Infact, I'm not sure if this is really needed, as I heard that only continuous (static) RF output is required. Can anybody confirm this or can help me with his knowledge?

Thanks and best Philipp

    For testing the radio against regulatory standards, FCC, ETSI, etc, I would recommend you to use the radio test example 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.

    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.

    I double checked with our testing house and having the ability for setting frequencies and data-rates is sufficient. I will adjust the radio test example.
