The National Instruments part number 780558-01 corresponds to the PXI-4132 PXI Source Measure Unit, engineered for high-precision voltage and current sourcing and measurement. It provides DC voltage ranges of ±10 V and ±100 V, along with versatile DC current source and sink options of 10 μA, 100 μA, 1 mA, 10 mA, and 100 mA. The voltage programming accuracy reaches 0.025% of the output, with specified offsets of 3 mV for the ±10 V range and 10 mV for the ±100 V range, featuring nominal resolutions of 50 μV and 500 μV respectively. Current programming accuracy is ±0.034% of the output, including suitable offsets based on the selected range and offering high-resolution capabilities down to 500 pA in the 10 μA range.

The PXI-4132 supports eight configurable PXI trigger lines with a minimum pulse width of 100 ns and features various output trigger events, including source complete and measure complete. It is suitable for operation in ambient temperatures ranging from 0 to 55 degrees Celsius and humidity levels of 10% to 70% (non-condensing), with a robust design for storage from -40 to 70 degrees Celsius and humidity levels of 5% to 95% (non-condensing). The unit can be operated at altitudes up to 2000 meters and complies with pollution degree 2 requirements.

Mechanical specifications include a weight of 295 g (10.4 oz) and dimensions of 2.0 cm x 13.0 cm x 21.6 cm (0.8 in. x 5.1 in. x 8.5 in.). It demands a power supply of 10 W at 5 V, 1 W at 3.3 V, and 2 W at 12 V. Additionally, the unit features load regulation characteristics of 0.5 mV per mA of output load via local sensing and maintains a stable operation with an operating shock tolerance of 30 g peak and vibration specifications from 5 Hz to 500 Hz at 0.3 grms for operational use. The PXI-4132 is designed to ensure reliable measurement and sourcing performance in various industrial applications.
