Optimize EVM
This is an "immediate action" function to optimize IQ data capture settings for best
EVM. It is used to set the combination of preamp, mechanical and electronic
attenuation and IF gain value based on measured signal peak level. Its purpose is to
get better EVM results by improving SNR and avoid ADC overload at the same time.
After this control is pressed, Pre-Adjust for Min Clipping changes to OFF and IF Gain
Auto changes to Manual.
