Re: Step-like behaviour of 6221 DC sweep for high ranges

Hello Andrea C, and thank you for reply! I get the point, that for higher ranges it is more sourcing error. I did some research and got interesting result, that for range 2e-6 current step value 47nA gives better results than other values: quantity "U-Ufit_line" has almost two times less interquarti...

Step-like behaviour of 6221 DC sweep for high ranges

Dear colleagues, I use 6221 to perform DC current (I) sweep through 2kOhm resistor. Voltage drop (U) across resistor is measured with 2182a nanovoltmeter. Since it is expected to get linear (I,U) curve, to control the accuracy of the experiment I consider quantity "U - Ufit_line", where "Ufit_line" ...
