You can learn more about e-corders by looking at range of data recorders and how they compare, videos, application notes and manuals.
Why can I see steps in my data instead of getting smooth curves?
It is likely that you have chosen a recording range which is too big and you are seeing digitization. If your peaks are only a few millivolts high, and you have left the default 10 volt range, you will see stepped peaks; the signal and areas will be inaccurate. You should select a recording range slightly higher than the largest signal you will record. Have a look at the Basics of Data Acquisition application note.
