Hi everyone.
first i must apology for my bad english.:D
I wanted to know what Ramp Up(RU) or Ramp Down(RD) means in this DDS and what it does.I read datasheet and searched through froum but couldn't find answer.
for example when i set DDS for an Eight-level modulation on Channel 0 with RU/RD, P0 ,P1 , P2 are for input binary bits and P3 is for RU or RD.
is this some modulation scheme or just a way to have better performance?
tnx anyway:D
