National Instruments PXIe-4143 PXI Source Measure Unit

The PXIe-4143 (Part Number: 782431-01) Source Measure Unit (SMU) incorporates a utility channel that can supply current or voltage with a 16-bit setpoint and an estimation resolution. The user can utilize this output, which gives up to 6 V and 1 A, as a complementary power supply to the SMU channel. Applications such as the characterization of transistors that require a steady current or voltage while sweeping another current or voltage can significantly profit by the lessened complexity, space, and cost offered by this module. For parallel test applications, the user can utilize 17 NI PXIe-4143 modules in a single PXI frame for 17 SMU channels and 17 programmable power supply channels in a 19-inch and 4U space.

The two channels of this PXIe 4143 SMU can act as a constant voltage source or as a steady current source, with a movable consistence restrict for any of the modes. Also, the user can empower remote sensing on the SMU channel to augment the exactness of output/voltage estimation on the gadget under test for high accuracy applications.

The PXIe-4143 SMU has estimation strategies that are generally based on the addition of current motions into the standard of the bipolar circuit and afterward into the voltage response estimation. This strategy is utilized if the device under test (DUT) has a low resistance; in case of high internal resistance of DUT, the addition of voltage motions is performed and after that the current reaction is estimated.
