National Instruments 785680-02 PXI Source Measure Unit

Part number 785680-02 from National Instruments is the identifying part number for the version of the PXIe-4162 PXI Source Measure Unit that has a current sensitivity of 10PA. This 12-channel device is equipped with a DC voltage range of ±24 V, providing the user with an incredibly sensitive and accurate performance for a wide range of applications. Capable of measuring voltage and current concurrently, the 785680-02 is an indispensable tool for test setups of all sizes.

The power required by the 785680-02 differs depending on the power rail, as well as on the specific cooling capacity of the chassis used. For a chassis with a slot cooling capacity of 38 W, the device draws in a typical current of 1 A from a voltage of +3.3 V and a typical current of 3 A for a voltage of +12 V. When a chassis is used that has a slot cooling capacity of ≥58 W, the typical draw for +3.3 V is 1 A, while a typical draw for +12 V is 4.5 A.

When in use, the 785680-02 can withstand operating shock with a peak of 30 g and a pulse of 11 ms. In addition, it can withstand random vibrations ranging from 5 Hz to 500 Hz. This SMU should only be operated in temperatures ranging from 0 °C to 40 °C, unless the chassis has a slot cooling capacity ≥58 W, in which case the operating temperature range is 0 °C to 55 °C. When in storage, the 785680-02 should be kept in temperatures ranging from -40 °C to 71 °C. The compact device weighs a mere 394 g (13.9 oz), and it measures dimensions of 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.).
