Description
The Part Number for this device is 782856-02, and it is identified as model PXIe-4139. This model falls under the category of PXI Source Measure Units, designed for precision measurement and control applications. A notable feature of this unit is its Terminals, which include Guard and Sense terminals on the output connector. These terminals are crucial for enhancing measurement accuracy and reliability.
The Guard Terminals are specifically used to implement guarding strategies in cabling and test installations. This is an important feature for reducing noise and improving the integrity of the measurements. On the other hand, the Sense Terminals are designed to compensate for current-resistance loss drops in cables and switches when remote sense is enabled. This ensures that the voltage at the device under test is accurate, despite any potential loss in the connecting cables.
Moreover, this unit is equipped with advanced Timing and Triggering Circuitry, which enables precise control of sourcing and measuring operations and synchronization with other devices. This is pivotal for applications requiring high precision and timing accuracy. The Sequence Engine further enhances the unit’s capabilities by enabling precise control over the sourcing functionality and fast, deterministic scheduling. This allows for efficient and accurate testing procedures.
The concept of Sequence Execution is integral to the operation of this unit. A sequence is described as a collection of setpoints executed consecutively. When Running a Sequence, the output values are applied in order or triggered at an exact time to configure the output to the next setpoint in the sequence. This feature allows for complex test procedures to be automated, improving test efficiency and accuracy.
