Optimize EVM
This is an "immediate action" function. 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.
This key is not visible for B25 IF bandwidth option. This key will be gray out if radio
standard is 802.11ac/ax 80+80MHz. and it will not be visible if radio standard is
11b/g.
After this key pressed, Pre adjust for min clip will be changed to off, IF gain auto will
be changed to Manu.
