Help with Constellation Graphs

Greetings.

I'm using a TMS320C6713 DSK and I need help with constellation graphs... I'm new at CCS and I'd like to make a constellation graph for a modulated signal like QPSK or QAM do any of you have any example of that??? I'm using CCS V3.1 and there is a constellation graph into the menu graphs but i dont understand how to configure the parameters of that window. thanks a lot

    Hi,

    The CCS help will definitely be a good reference for this type of graph.

    Either click on the Help button at the Constellation graph or go to menu Help --> Contents --> Debugging Windows & Analysis Tools --> Graphing Data Output from a Program --> Types of graphing Windows --> Constellation Diagram.

    For other concepts like Q-value you can find information at the Wikipedia.

    Hope this helps,

    Rafael

    Thanks Rafael but it did't help... i clicked on help buttom of constellation graph and this message showed:

    "the topic does not exist. please contact the application vendor to obtain an updated help file. (129)" and using the CCS help only show the meaning of constellation but doesn't say anything of how to configure the window for that type of graph
