There is no effect when I want to specify FIR attenuation and set Astop parameters.The matlab version I used was R2016a,The version of the AD9361_Filter_Wizard I use is 16.1.3.

The effectiveness of Astop will be dependent on the design as the wizard is best effort. As with the standard Parks Mcclellan, it doesn't guarantee a specific ripple or attenuation.

But Astop does work: Screenshot_20190827_100944 Screenshot_20190827_100917
