National Instruments PXIe-4139 PXI Source Measure Unit

The PXIe-4139 (Part Number: 782856-02) Source Measure Unit highlights Guard and Sense terminals on the output connector. The user can utilize Guard terminals to actualize guarding strategies in cabling and test installations. It is also possible to use Sense terminals when remote sense is empowered to compensate for current-resistance loss drops in cables and switches. The timing and triggering circuitry of the NI PXIe-4139 System SMU empowers exact control of the sourcing and estimating tasks and synchronization with different gadgets. For data about the specific triggers and events that are accessible for the PXIe-4139, the sequence engine empowers exact control over the sourcing functionality of the gadget and empowers quick, deterministic planning. Furthermore, sequencing can be used with the estimation usefulness of a gadget to accomplish estimation timing.

A sequence is a gathering of setpoints that are executed consistently. A setpoint is a solitary output setting for the gadget. There are two techniques for running a sequence: The user can apply output esteems in succession—one setpoint followed by its relating source delay, quickly taken after by the following setpoint. The user can also utilize a trigger on the National Instruments PXIe-4139 SMU to configure the output to the next setpoint in the sequence at an exact time, followed by its relating source delay. While setting off a succession, just a single setpoint taken after by its source delay is connected per received trigger.
