The nrf52833‘s RF power accuracy does NOT meet the requirements of Telec

[Aape]

Hi，

We had some trouble doing the certification of Tepec， Telec certification requires the RF power accuracy of ±3.8dB , while it is ±4dB in spec。Do you have any good advice for me？

Hi Dejans and Aape,

From my experience view point, if you apply TELEC in the condition of the theoretical output power with - 4dB to + 0.75dB, your EUT will be approved by TELEC.

By the way, In the case of +8dBm ±4dB under the Nordic proprietary mode, the theoretical maximum RF power is 12dBm, so there is also the same problem in EN300 328.

How about any idea for solving?

Could you please revise the RF power accuracy in line with reality?
