The PXIe-4145 has a resolution of 100 ppm when set to a 100 μs aperture time. In the 6 V range,
resolution can be calculated by multiplying 6 V by 100 ppm, as shown in the following equation:
6 V * 100 ppm = 6 V * 100 * 1×10-6 = 600 μV
Likewise, in the 10 mA range, resolution can be calculated by multiplying 10 mA by 100 ppm,
as shown in the following equation: 10 mA * 100 ppm = 10 mA * 100 * 1×10-6 = 1 μA
