Does anyone know how I can vary measurement speed during output. I am sourcing a fixed current for a constant 5 mins and would like to sample at say 2000 points in the first minute and the last 500 in the final 4 mins. Does anyone know how to do this? Would I use two arm counts with different NPLCs? The problem is I would like to but, would also like the current source to stay on (sourcing current) the whole time. I don't want to stop the code, turn it off, gather data, and then turn it back on. However, if necessary I can. Also for reference I'm using GPIB and LabVIEW to program it.
