Hello,Kristien

Thanks for your prompt reply.

I would like to know how to measure the power ripple μVrms and noise spectral density (μVrms/RtHz). What equipment is needed? Can you provide relevant test instructions?

Look forward to your reply.

Hello,

Thank you for the clarification. One of our hardware engineers will provide more information within the next business day on the best process for obtaining power measurements.

Thank you for your patience,

Kristien

Hi Baoxiang wang,
    Can you please let me know from where did you find the attached image? I am only able to find below image for Ripple specification from the datasheet.

You can measure this spec (Vrms value of frequency components in a supply rail) using a spectrum analyzer. Please ensure that you are tapping/measuring the supply rail from where it is directly fed to respective BGA balls of the AWR1843AoP. Spectrum analyzer will be able to support measurement in Vrms. If not, please use dBm to Vrms converters which you can easily find on internet.

Thanks and Regards,
