Description
The part number 782856-02 refers to a PXI Source Measure Unit categorized under PXI Source Measure Units. This specific model, named PXIe-4139, is designed as a Primary Side Analog Shield, making it a System SMU (Source Measure Unit) that comes with a higher power option. It features Guard and Sense terminals for its output connectors, which are essential for various purposes.
The Guard Terminals are specifically designed for implementing guarding strategies within cabling and test setups, ensuring that the measurement integrity is preserved by minimizing the influence of stray capacitance and leakage currents. On the other hand, the Sense Terminals are invaluable for remote sensing. This feature compensates for the voltage drop that occurs in cables and switches, ensuring that the voltage applied to the device under test (DUT) is accurate, which is critical for precision measurements.
Furthermore, the PXIe-4139 boasts advanced Timing and Triggering capabilities. This functionality enables precise control over both sourcing and measuring operations, ensuring that they can be perfectly synchronized with other devices within a test system. This level of control is crucial for complex or time-sensitive testing scenarios.
An additional noteworthy feature is the Sequence Engine. This engine provides the ability to precisely control the sourcing functionality and measurement timing through deterministic sequencing. This means that the output values can be applied in a sequence with source delays, and these sequences can be triggered to align with exact timing requirements. The Sequencing Method thus allows for sophisticated test sequences that meet stringent timing constraints, enabling highly precise and repeatable measurements.
