I am using the TDS 2001C 50MHz Two Channel Digital Storage Oscilloscope. As long as I can redcord the time and voltage I can plot the waveshape later as I am measuring from a PCB using a probe. 

I want to be able to save continuous voltage measurements over a period of 1 hour but am having a hard time finding a way to change the capture settings. Currently, when I choose save/recall and save the data measured at 1s, the waveform is captured for ~10s. How would I change this so the waveform is captured for larger periods of time and is able to be saved as a CSV file? 

Thanks!
