PXIe-4142 Product Usage Instructions

To use the PXIe-4142, follow the steps below:

1. Select a voltage or current range from the table provided in the user manual.
2. For a given aperture time, find the corresponding resolutionfrom the figure provided in the user manual.
3. To convert resolution from ppm of range to absolute units, multiply resolution in ppm of range by the selected range.

It is important to note that accuracy is specified for no load output configurations and additional accuracy derating and conditions may apply for load regulation and remote sense. The device also has additional specifications such as settling time, transient response, wideband source noise, cable guard output impedance, maximum lead drop, isolation voltage, channel-to-earth ground, and absolute maximum voltage between any terminal and LO, which can be found on page 6 of the user manual.

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-4142 has a resolution of 1,000 ppm when set to a 100 μs aperture time. In the 24 V range, resolution can be calculated by multiplying 24V by 1,000 ppm, as shown in the following equation:
24 V 1,000 ppm = 24 V 1,000 1 × 10-6 = 24 mV
Likewise, in the 150 mA range, resolution can be calculated by multiplying 150 mA by 1,000 ppm, as shown in the following equation:
150 mA 1,000 ppm = 150 mA 1,000 1 × 10-6 = 150 μA
