dds ad9858

Dear Friends
I wnat to use AD9858 in linear sweep mode but i cant program dds with related value in DFTW and DFRRW regs.
all values was calculated based on datasheet equations but i did not give any answre.
my setting parameters are:
T=10Sec.(time interval from start frequency to finish frequency)
Fs=10MHz
Ff=25MHz
DFTW=182
DFRRW=8191

i checked with different values but i see different sweeping schem.
can anyone help me?
tnx in advance

which kind of mcu which you control the ad9858
are you sure that the time Sequential logic is right?
