    Calculating SMU Resolution

    Refer to the following figure as you complete the following steps to derive a resolution in absolute units:

    Figure 2. Noise and Resolution versus Measurement Aperture, Typical
    1. Select a voltage or current range.
    2. For a given aperture time, find the corresponding resolution.
    3. To convert resolution from ppm of range to absolute units, multiply resolution in ppm of range by the selected range.

    Example of Calculating SMU Resolution

    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
