Re: A question about the Rising/Falling Sweep Ramp Rate of AD9915

Dear Sercan,

I had one more question,

In your file ANI_Ramp_Rate__AMP.STP.ZIP,

Your Digital Ramp Upper Limit Register(0x05) = 00000FFF

This would be putting FFF in the lowest 12 bits(11:0) , I think.

But, on the Table 9, on p23 in AD9915 Rev.D,  when Amplitude is selected,

it says upper MSB's are sent to the DDS. 

So it would look like you would want

the register(0x05)=FFF00000 ?

I dont have my own eval board yet, so I did not know if you manually made this

ANI_Ramp_Rate__AMP.STP.ZIP file,

or if the software makes it from what you enter into GUI boxes?

Thanks for helping my curiosity!

Sincerely,

Steve
