Hi Team

I am trying to measure RF Power of CC2640R2F by using Launchpad but i am not getting anything on spectrum Analyzer.

But when i am trying to measure output RF power of Launchpad itself then its coming. Only difference is i am using CC2640R2F design with PA (CC2592).

Is there any other way to measure RF power with PA design?

Another Query, In SmartRF Studio when i am selecting CC2640R2F then still it is showing CC2650 design in drop down list not CC2640R2F.

You have to click “customize...” button on top-right corner of Smart Studio to assign PA/LNA pins to control CC2592. By the way, it’s correct to see CC2650 design in drop down list not CC2640R2F in SmartRF Studio when you select CC2640R2F.

Hi Yikai,

Thanks for input. I am getting power now after setting DIO for power amplifier.

I wanted to know one thing, What is the register value to set PIN= 0dBm and 2dBm (in case of 4x4 single ended CC2640R2F) so that we can get output RF power accordingly?
