This is not strictly a LabVIEW question but one of you might have an answer. I found an old VirtualBench in one of my drawers of NI Stuff. It's exactly what I need for my appication. I'm using it in oscilloscope mode. When I export the data to a CSV file, I have a column for time, min and max. What is the significance of min and max, and how are these values calculated? When a colleague used it to measure a bipolar signal, there were two very different min/max waveforms. The min waveform was also bipolar. How do I merge these into one waveform? My googling has been useless at answering this question.
