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

Select a voltage or current range.
For a given aperture time, find the corresponding resolution.
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-4141 has a resolution of 100 ppm when set to a 100 μs aperture time. In the 10 V range, resolution can be calculated by multiplying 10 V by 100 ppm, as shown in the following equation:

10 V * 100 ppm = 10 V * 100 * 1×10^-6 = 1 mV

Likewise, in the 100 mA range, resolution can be calculated by multiplying 100 mA by 100 ppm, as shown in the following equation:

100 mA * 100 ppm = 100 mA * 100 * 1×10^-6 = 10 μA

¹ The ambient temperature of a PXI system is defined as the temperature at the chassis fan inlet (air intake).
² Channels are isolated from earth ground but share a common LO.
³ Accuracy is specified for no load output configurations. Refer to Load Regulation and Remote Sense in the Additional Specifications section for additional accuracy derating and conditions.
⁴ Current limit set to ≥1 mA and ≥10% of the selected current limit range.
⁵ Channels are isolated from earth ground but share a common LO.
⁶ When source-measuring, both the niDCPower Source Delay and niDCPower Aperture Time properties affect the sampling rate. When taking a measure record, only the niDCPower Aperture Time property affects the sampling rate.
⁷ Load dependent settling time is not included. Normal DC noise rejection is used.
