problem with analysis, modifying and storing a real time signal

[sukhiray]

I have to analysis a real time signal. I have acquired signal properly. Now I have to do three major things---

1. I have to change the time axis into deg. the relation b/w these two is like that

                                                      deg. value, say, D=t*5000*75                          t is in sec.

         and then have to plot the signal against this D

2. Now I have to store the signal values in Excel file.

3. I just have to plot only one cycle of this signal and have to stop the program automatically just after plotting one cycle of the signal. (I think, as it is a real time signal nothing but comparing the amplitude can help to detect the completeness of the cycle.)

Please help me to solve this problem.

sukhiray,

It sounds like you know exactly what you are wanting to do.  Where are you having troubles?  What have you tried?  Have you looked at examples for logging data to a spreadsheet?  If you could post your code with what you have so far and where you are running into problems, we'll be more than happy to help.  More information is needed to be able to help you solve your problem as you've just described your goal, not where you are needing assistance.
