CW Mode only outputs +13dBm when using nRF9160 DK

[Patrick van der Vlist]

Hi,

We are having issues with getting the output power of +23dBm when using the nRF9160 DK in CW mode.

We use the following command:

AT%XRFTEST=1,1,20,8470,23,1,4,0,0,0,0,0,0.

When measuring the conducted output power, we only measure +13dBm at J1.

Is it even possible to output the +23dBm?

Kind regards,

Patrick van der Vlist

Additional information, the return value is 384

Hi Patrick, 

Looks like you have configured the correct parameter. 

The return value shows that you have 24dBm in output so it might be a physical loss? is there any attenuation here that is not accounted for ?
