Re: How to calculate AD9858 DFTW and DFRRW ????

Hi

In Sweep mode first we assigned CFR Address like 

0x00 [7:0]     01101000

0x01 [15:8]   10000000

0x02 [23:16] 10000000 also Explain me about Load Delta Frequency Timer ????this bit be high or low in sweep mode

then  loaded start frequency into FTW0

after we assign DFTW ....suppose we load 1 MHz DFTW 0004294968 Decimal

then we loaded DFRRW 65635 ....524.280uS

Result:

There is no sweep or output

i dont know where i am wrong  kindly help me out

Thanks
