Give a brief description of how Direct Digital Synthesis works,
then describe how the parameters of the AD9851 define its region
of performance.
Work in the Lab
In this section,
talk about the
process
of configuring equipment, collecting data,
overcoming difficulties,
and achieving desired results.
As usual, mention any problems that you encountered and describe
how you overcame them.
Results from the Lab
In this section you should present and summarize
the data which you have collected
and discuss what it means.
Discuss the mesaurements that you made and the waveforms you
observed in the context of
utilizing the AD9851 DDS as source of RF signals.
As usual, include single point, tabular, and graphic
data as appropriate.
Design Discussion
Discuss the design of the DDS board used in this Exercise.
Describe the purpose of each component or group of components.
Discuss the operation of the
vco.c
program.
Is the observed range of frequency variation consistent with your observations?
Describe how it might be changed.
Design Challenge
Describe the thinking behind your design
and the work you did to realize it.
Include a listing of your program.
