Description
The 132743B-01L is a part of the PXI Source Measure Units category, specifically the PXIe-4139 model. This system SMU, known as the NI PXIe-4139 System SMU with Higher Power Option, is designed to provide users with advanced capabilities for both sourcing and measuring operations within their testing environments.
It features Guard and Sense terminals on the output connector. The Guard Terminals are crucial for implementing guarding strategies in cabling and test fixtures, which is essential for reducing noise and ensuring accurate measurements. Meanwhile, the Sense Terminals are designed to compensate for voltage drops that occur due to cable and switch resistance, especially when remote sense is enabled. This functionality is critical for maintaining the accuracy of measurements in setups where the device under test is located far from the source measure unit.
The Timing and Triggering capabilities of the PXIe-4139 allow for precise control of sourcing and measuring operations. This feature is vital for applications requiring synchronization with other devices, enabling users to achieve highly accurate and repeatable measurements. Furthermore, the built-in Sequence Engine provides users with precise control over sourcing, along with quick, deterministic timing for measurement functionality. This engine supports Two methods of Sequence Execution: applying output values in a sequence or using a trigger to configure the output at an exact time. These features collectively enhance the flexibility and efficiency of testing procedures, making the PXIe-4139 a versatile tool for a wide range of applications.
