Hi there,
DIAdem is intended to find data, to analyze data, to run analyses, to create reports, and combine all functions to a script. Data is not generated in DIAdem. If you have an rpm signal that you would like to read into DIAdem for analysis, you would use the DIAdem NAVIGATOR to load this data into DIAdem. In the ANALYSIS tab, you will be able to run the data through an equation to convert from sound pressure to db. To help you begin the process of importing data and analyzing the data, please refer to DIAdem Help->Contents->Basics->Navigator and Analysis.
If you have any further questions, please give a specific instance or describe in more detail what you would like to do. From what I am understanding of your post, the answer is yes, you can use the Analysis tab to convert data, yes you can import signals that already exist into DIAdem. Please post back if you have any further questions and good luck with your project!
