National Instruments 784483-02 PXI Source Measure Unit

Part number 784483-02 from National Instruments is the identifying part number for the version of the PXIe-4163 PXI Source Measure Unit that boasts a current sensitivity of 10 PA. This multipurpose SMU has a DC voltage range of ±24 V and features 24 channels, which are labeled 0 to 23. For improved connectivity, the 784483-02's front panel is fitted with unique, 62 slot female D-SUB connectors. This unit offers incredibly precise and accurate measurement capabilities for test setups and applications of all sizes.

The power required to operate the 784483-02 differs depending on the type of chassis used. For a chassis with a slot cooling capacity of 38W and a full output load, the device draws in a typical current of 1 A for +3.3 V and a current of 3 A for +12 V. For a chassis with a slot cooling capacity that is greater than or equal to 58 W (also with a full output load), a voltage of +3.3 V draws in a typical current of 1 A while a voltage of +12 V draws in a current of 4.5 A.

The compact, one slot design of the 784483-02 is made to withstand a wide range of environmental factors. It should be operated within temperatures ranging from 0 °C to 40 °C (or 55 °C, with chassis slot cooling capacity of ≥58 W) and a noncondensing humidity range of 10% to 90%. It can be safely stored in temperatures ranging from -40 °C to 71 °C. The 784483-02 measures 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and weighs 394 g (13.9 oz).
