National Instruments 780558-01 PXI Source Measure Unit.

The part number 780558-01 from National Instruments is the identifying part number for the PXI-4132 PXI Source Measure Unit. This PXI source unit is designed for precision voltage and current sourcing and measurement capabilities. This unit supports DC voltage ranges of ±10 V, and ±100 V with DC current source and sink ranges of 10 μA, 100 μA, 1 mA, 10 mA, and 100 mA, allowing for precise current control. Voltage programming accuracy is specified at 0.025% of output plus an offset (3 mV for ±10 V range and 10 mV for ±100 V range), with nominal resolutions of 50 μV and 500 μV respectively. Current programming accuracy is ±0.034% of output plus an offset, depending on the range, with resolutions as fine as 500 pA for the 10 μA range.

This PXI Source Measure Unit supports input trigger lines that are configurable through 0 to 7 PXI trigger lines with a minimum pulse width of 100 ns, nominal and output trigger events of source Complete, sequence Iteration complete, sequence engine is done, measure complete, pulse complete, and ready for a pulse and has configurable PXI trigger lines through 0 to 7 with a pulse width of between 150 ns and 1.6 µs.

This PXI unit is designed to operate at an ambient temperature of 0 to 55 degrees Celsius with operating humidity of 10% to 70%, noncondensing, and storage temperature of -40 to 70 degrees Celsius with storage humidity of 5% to 95%, noncondensing. It is required to be mounted at a maximum altitude of 2000 meters with a pollution degree of 2. Its operating shock value range is 30 g peak, half-sine, 11 ms pulse while its operating vibration range is 5 Hz to 500 Hz, 0.3 grms, and its nonoperating vibration range is 5 Hz to 500 Hz, 2.4 grms.

This 780558-01 Source Measure Unit includes load regulatory features of 0.5 mV per mA of output load using local sense and 0.01% range per volt of output change, thus these safety features ensure a reliable operation. To power this PXI unit, 10 W at 5 V, 1 W at 3.3 V, and 2 W at 12 V is required. Physically, this module has dimensions of 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and it weighs 295 g (10.4 oz).
