    Thread Summary
    
                The user is experiencing issues with the AD9914 DDS where the output pulse shape is not as expected when using ASK and PSK modulation with the OSK pin and profile selection. The final answer indicates that the user is using a microcontroller to control the DDS, but does not provide a specific solution. The accompanying answer mentions setting up two profiles with a 90-degree phase offset and using a Raspberry Pi to switch the PS0-Buf pin, but the profile selection is not triggering correctly.

     i'm using on  ad9914  dds using ask modulation and psk modulation using osk pin and profile selection how set register value. i'm given outside pulse to profile register and code is given in osk pin .my problem not get the output pulse shape not coming?
    

    plz tell me correct answer ....
