According to the data sheet the minimal increment using 8bit resolution is 0.4% of full scale but the minimal increment of the stored data in my example is approx. 0,8% of full scale. The difference between the data sheet value and the real value for the minimal increment is factor 2. Why there is a difference? Did I make a mistake?

Sorry! Last time I forgot the attachment. I hope all needful information can be taken from the figure.

I can't determine the 0.8% minimum increment you are referring to from your attachment. The 0.4% mimimum increment simply comes from the fact that we use an 8-bit ADC, which is 256 discrete levels across full scale. The resolution of an 8-bit ADC is inherently 0.4%. Please clarify the 0.8% that you are referring to.
Thanks,

the 0.8% results of the data acquisition process. In my example the minimal increment of two data points complies 0.8% of full scale (not 0.4%). The data was acquired using the GPIB interface and VISA instructions.
