CC3200: TX Error Vector Magnitude vs. TX power Level

Antenna_Head

Genius 13000 points

Part Number: CC3200

Team-

Do we have an plots of TX Error Vector Magnitude vs. TX power level?

If so, can you please provide plots for the various modulation formats?

Thanks, Best, S. Dunbar, AFA Colorado

Hi Steve,

We don't have this graph/data readily available.

Do we expect that the TX Error Vector Magnitude will vary with TX power setting?

Is there data available internally that I could review?

Change in TX power should affect EVM.

should or shouldn't?

Lowering from full power may improve EVM, but if you get too low it wouldn't.

It is not linear, so change in TX power does not result in equivalent change in EVM.
