Description
The Part Number 782856-02 corresponds to the PXI Source Measure Units category, specifically the model PXIe-4139. This model is known as the NI PXIe-4139 System SMU, which stands out for its advanced features tailored for precise measurements and control in complex systems.
One of the key features of this model is its Output Connector Features, which include Guard and Sense terminals. The Guard Terminals are crucial for implementing guarding strategies in cabling and test setups, which is essential for reducing noise and improving measurement accuracy. On the other hand, the Sense Terminals play a vital role in compensating for voltage drops in cables and switches when remote sense is enabled, ensuring that the voltage applied to the device under test is accurate.
The Timing and Triggering capabilities of the NI PXIe-4139 System SMU enable precise control and synchronization with other devices, which is critical for complex test and measurement setups that require high precision. Additionally, the Sequence Engine allows for exact control over sourcing and measurement timing, providing users with the flexibility to define specific test sequences.
There are two main Sequencing Methods supported by this model. The first method involves applying output values in sequence with source delay, which is useful for tests that require the application of different voltages or currents in a predefined order. The second method utilizes a trigger to configure the output to the next setpoint at an exact time, followed by its source delay. This method is particularly useful for synchronized operations among multiple instruments or when precise timing is crucial.
