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?
Inside the ADIsimRF, I see a strange behaviour:
- seems that DGA4 is not correctly "modeled" (or something wrong in any case), because I see only two values (13,2 and 19,2...)
But when I chose one of those two value, the program, answers with
