AD9361 Digital Gain

Hello everyone,


According to UG-570 page 38 "DIGITAL GAIN":

""For many applications, digital gain is not needed. Further, modifying the gain table and sacrificing analog gain to add more digital gain will decrease the performance of the system.""


Why digital gain will decrease the performance? Will the digital gain make received signal distortion?

If so how can I turn off the digital gain?

Is the FIR's gain a kind of digital gain?


Please answer this question for me, thanks a lot!!
