National Instruments 782431-01 Precision PXI Source Measure Unit

The National Instruments 782431-01 is the descriptive part number for the PXIe-4143 Precision PXI SMU. Equipped with 4 channels that each support a voltage range of ±24 V, the 782431-01 is a perfect choice for applications that require a high pin count. Specifically designed with versatile capabilities for measuring voltage and current sources, the device offers incredible precision to automated test and measurement applications. The front panel connectors are male 25-position D-SUB connectors. 

Each individual channel of the 782431-01 can support a voltage range of ±24 V as well as a source and sink current range from 10 μA to 150 mA. These channels share a common LO but are isolated from earth ground, allowing for useful flexibility with various measurement and sourcing configurations. The rapid sample rate of the 782431-01 allows the device to shorten measurement times, which in turn expedites the characterization of the devices under test. Source Measure Units from NI are able to be easily synchronized with additional instruments such as digital test modules and switches. 

When it comes to dynamic test scenarios, the 782431-01 showcases incredible performance with a transient response of <100 μs to recover within ±20 mV. The device also boasts a variety of features that enhance performance, such as low wideband source noise and a settling time of <100 μs. 

Physically, the 782431-01 SMU measures 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) in dimensions. Easy to affix in a variety of test setups, the device weighs only 412 g (14.53 oz).
