"The simple way to save the waveform is to set up acquisition parameters as required, make a measurement and save the waveform to USB drive in *.csv format."
Can this also be done in Tektronix Openchoice Desktop application software ? i.e, to save the waveform in picture and also save the waveform as data in *.csv file ? How about if I need to run longer for example, 5 min etc. I guess oscilloscope can't handle this. How about using Openchoice software if it can utilize more memory from PC ?
