difference between tx carrier modulated and not

[annapalu]

Hi All,

I need to certificate the nrf52 to Fcc. I understood that the radio test is very useful. I try to clarify what the code permit to do, because i want to adapt it for the test. In particular, i don't understood the difference between the

• Start TX Carrier and Start Modulated TX carrier.

Instead of The tx sweep permit to change the channel of transmission after a time that we can insert with command d ( Enter time on each channel (1 ms - 99 ms)). The same is for the RX channel, correct?

A last question is about the power. How Can i set the transmission power to max power?

thanks, Anna

Thank you for the answer. I'm a little confused, searching on the forum i find that DTM example can be used for the FCC test. What is the differents between DTM and radio_test? Thanks, Anna

DTM is not made to be used for radio testing (FCC). DTM is specified in the Bluetooth Core Specification, and is intended to be used for BLE testing.

When qualifying for FCC, the radio itself is being tested, and the radio_test example is a lot better for that purpose.
