The following is the list a set of tasks that has to be done on the DDS system :
a.A better heat sink for the regulators.
b.The power on reset circuit is not functioning. So a computer reset to the DDS system is required after power on.
c.The feed back circuit is not tested.
d.The opto-isolators are presently bypassed. This means that there is no ground isolation between computer ground and DDS system ground.
