These specifications apply to the PXIe-4141.
Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.
Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.
Specifications are valid under the following conditions unless otherwise noted.
The following table and figure illustrate the voltage and the current source and sink ranges of the PXIe-4141.
Channels | DC Voltage Ranges | DC Current Source and Sink Ranges |
---|---|---|
0 through 3[2] | ±10 V |
|
Range | Resolution and noise (0.1 Hz to 10 Hz) | Accuracy (23 °C ± 5 °C) ± (% of voltage + offset)[3] | Tempco ± (% of voltage + offset)/°C, 0 °C to 55 °C | |
---|---|---|---|---|
Tcal ± 5 °C | Tcal ± 1 °C | |||
10 V | 10 μV | 0.015% + 600 μV | 0.013% + 150 μV | 0.0005% + 1 μV |
Refer to the following figure as you complete the following steps to derive a resolution in absolute units:
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
