National Instruments 782435-01 Precision PXI Source Measure Unit

The National Instruments 782435-01 is the descriptive part number for the PXIe-4145 High-Precision PXI Source Measure Unit. With 4 channels that each feature a DC Voltage Range of ±6 V, the device offers capabilities for a wide range of test and measurement setups. Especially suited for applications that have high pin counts, the 782435-01 boasts an incredibly fast sample rate that quickly characterizes devices under test and shortens measurement times. By using SourceAdapt technology, the stability of the device can be maximized in reaction to any load. In addition, a high-speed sequencing engine can be employed in order to synchronize the SMU with a selection of instruments- including digital test modules and switches.

One of the standout features of the 782435-01 is it’s four-quadrant operation, which enhances the device’s capabilities for test and characterization. The channels are integrated with 4-wire remote sensing and works with a source and sink range of 10 μA to 500 mA for DC current. The device also features various trigger types, including Start, Source, Sequence Advance, and Measure. These flexible triggers boast configurable polarity, allowing the user to tailor the device to the specific needs of the test setup. With male D-Sub (25-position) connectors on the front panel, the 782435-01 makes connectivity a breeze.

The power required for the 782435-01 varies depending on the voltage. A 12 V rail results in 2.1 A, while a 3.3 V rail results in 2.9 A. This SMU operates most effectively within an operating temperature range of 0 °C to 55 °C, and it’s physical dimensions measure 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.). The device weighs only 408 g (14.39 oz).
