National Instruments 786888-01

The National Instruments part number 786888-01 identifies the PXIe-4147 Source Measure Unit, designed for precision source and measurement applications with its four-channel, four-quadrant operation. This versatile device is capable of high-resolution output and can synchronize with a range of instruments using its high-speed sequencing engine. The PXIe-4147 supports a nominal sample rate of 1.8 MS/s per channel and offers a maximum output voltage of 8 V, making it adaptable for various testing scenarios. Connectivity is facilitated via 25-position male D-SUB connectors on the front panel, with four input triggers that can be sourced from either PXI or software, enabling efficient synchronization across boards. The trigger types include Sequence Advance, Start, Measure, and Source. Enhanced safety features are integrated into the design, protecting the device from overvoltage with an absolute maximum voltage rating of ±60 V for all pins (except the Output HI, which is rated at ±10 V), as well as providing overheating and overcurrent protection through an automatic shutdown feature. The PXIe-4147 measures 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and weighs 448 g (15.8 oz at 20 W) or 428 g (15.1 oz at 40 W). Designed to operate in environments with a temperature range of 0 °C to 55 °C and a non-condensing humidity range of 10% to 90%, the PXIe-4147 is a robust choice for demanding industrial applications. It is backed by a three-year warranty, ensuring reliability and performance.
