I'm trying to simulate ADRF6518 using adisimRF. As I'm able to see, It is possible to drive digital vga1, vga2, vga3 and postamp (2+2+2+1 bits) to control gain between 33 to 66 by 3dB steps.

Using analog vgn1, vgn2, vgn3, it is possible to control gain/attenuation of 24 dB each vgn (72 dB total).

this is correct?

But when I chose one of those two value, the program, answers with

 

let me know

 

best regards
