I am doing QPSK modulations on given data using AD9856.
I am getting modulated signal with some pulse shaping.
I just wanted to confirm that in AD9856 is there any inbuilt functionality to generate Modulated data in some specific pulse shaping.
No, the AD9856 does not offer any pulse-shaping functionality. Please note that if you do some pulse shaping to the data prior to inputting it into the AD9856, there are implications on the AD9856 functionality - be sure to read the section on the half-band filters in the AD9856 (pg 20 of the datasheet) if you implement pulse-shaping.
