The National Instruments 784483-02 PXIe-4163 Source Measure Unit is designed for demanding test and measurement applications, featuring a current sensitivity of 10 pA and a DC voltage range of ±24 V. This versatile instrument comprises 24 channels, numbered 0 to 23, and is equipped with robust 62-slot female D-SUB connectors for enhanced connectivity. The PXIe-4163 delivers precise and reliable measurement capabilities, suitable for various test setups. Its power consumption is dependent on the chassis cooling capacity; under full output load, it typically draws 1 A at +3.3 V and 3 A at +12 V for a chassis with a 38W cooling capacity, while requiring 1 A at +3.3 V and 4.5 A at +12 V for a setup with a 58W capacity or higher. The unit’s compact design, measuring 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and weighing 394 g (13.9 oz), is engineered to function optimally in environments ranging from 0 °C to 40 °C, with enhanced performance up to 55 °C with appropriate cooling. It can be safely stored in temperatures between -40 °C and 71 °C. The PXIe-4163 is backed by a three-year warranty, underscoring National Instruments' commitment to quality and reliability in industrial automation and control systems.
