National Instruments 782856-01 PXI Source Measure Unit

The National Instruments part number 782856-01 is the identifying part number for the PXIe-4138 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 600 mV, 6 V and 60 V with DC current source and sink ranges of 1 μA, 10 μA, 100 μA, 1 mA, 10 mA, 100 mA, 1 A and 3 A, allowing for precise current control. The 782856-01 offers extraordinary accuracy and and low noise performance with voltage resolution of as low as 1 μV with an accuracy of 0.02% + 100 μV and current resolution of as low as 100 pA with an accuracy of 0.03% + 12 nA at ambient temperature of 23 degrees Celsius.

This 782856-01 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 done, measure complete, pulse complete, and ready for pulse and has configurable PXI trigger lines with a pulse width of  between 250 ns and 1.6 μs.

This device includes protective features as well such as the overvoltage or overcurrent protection and overtemperature protection with automatic shutdown and output disconnect relay opens, thus with these safety features it ensures a reliable operation. To power the 782856-01, 2.5 A of current from the 3.3 V rail and 2.2 A of current from the 12 V rail is required. It has physical dimensions of 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and it weighs 419 g (14.8 oz).

This PXI unit is designed to operate at temperature of 0 to 55 degrees Celsius with operating humidity of 10% to 90%, noncondensing and storage temperature of -40 to 71 degrees Celsius with storage humidity of 5% to 95%, noncondensing. It is required to mount at maximum altitude of 2000 meters with a pollution degree of 2. It operating shock value range is 30 g, half-sine, 11 ms pulse while its operating vibration range is 5 Hz to 500 Hz, 0.3 g RMS.
