Description
The Part Number for this device is 782856-02, categorizing it under PXI Source Measure Units. Specifically, the model in discussion is PXIe-4139, known as the NI PXIe-4139 System SMU. This system features Guard and Sense terminals on the output connector, which are crucial for its operation.
The Guard Terminals are used to implement guarding strategies in cabling and test fixtures, which is essential for maintaining signal integrity and reducing noise. On the other hand, the Sense Terminals are designed to compensate for voltage drops in cables and switches when remote sense is enabled, ensuring that the voltage applied to the device under test is accurate.
One of the key features of the PXIe-4139 is its Timing and Triggering capabilities, allowing for exact control of sourcing and measuring operations. This is further complemented by the Sequence Engine, which enables precise control over sourcing and measurement functionality for fast, deterministic timing. The Sequencing Method allows output values to be applied in sequence or triggered to change at an exact time, facilitating complex test scenarios and precise control over the test sequence.
