Part Number: AWR2243

Is there a way to operate the chip in single tone continuous wave operation?

I would like to perform phase noise measurements.

Hello Gabriel,

Yes, there is a Continuous Wave (CW) mode which can be used for your purpose. Please refer to some similar threads linked below :

Hope this helps. Please let us know if you any other concerns.

Thanks Ishita.

I was able to track the function rlDeviceSetConStreammingModeConfig function located in rl_device.c file.

What determines which TX and single tone frequency is used when enabled? Is this based on the chirp profile enabled TXs and start frequency since it is a 0 slope?

Does this continuously generated ADC data?

Hello Gabriel,

Yes, the start frequency is programmable and this is what determines the frequency tone used.

On the TX used, that is determined by the TXs enabled by you in the Channel Static configuration.
