it seems there is am Limit of 1048580 Values(Lines) for the .cvs or .txt export. Is this on purpose? This is kind of a waste, as this limits you to 1MS resolution...
If this is a hard Limit of Windows, why not save the Data in several subsequent files?
My problem for example is, that i want to record a 500ms initialisation phase of a bus signal. With 1MS i have a resolution of 5µs. As one bit is about 4-6µs long i only get rubbish. With 10MS (or 100MS) it would work just nicely.
