In the Spec. we only see TX EVM v.s. TX ATT as shown in attached figure. We want to know AD9361 correlation between output power and EVM (%rms). When we tune the output higher or lower and the changes of EVM.
Can you please share details on how you are planning to tune the output higher or Lower. ?
When we adjust to Max power 7dBm then what the reuslt of EVM. And as we increase the attenuation 1dB, 2dB....20dB (power=6dB,5dB...-13dB), what will change in EVM.
Figure 21 , As attached in your first post gives the variation of EVM with attenuation .
While using a modulated waveform , you need to take care of the peaks as well and the Average output power depends on the PAR of the signal waveform. As long as you ensure that the peaks are not clipped there will not be any degradation to EVM.
