PXI-7851

The PXI‑7851 features a user-programmable FPGA for high-performance onboard processing and direct control over I/O signals to ensure complete flexibility of system timing and synchronization. You can customize these devices with the LabVIEW FPGA Module to develop applications requiring precise timing and control such as hardware‑in‑the‑loop testing, custom protocol communication, sensor simulation, and high-speed control. The PXI‑7851 features a dedicated A/D converter (ADC) per channel for independent timing and triggering. This design offers specialized functionality such as multirate sampling and individual channel triggering, which are outside the capabilities of typical data acquisition hardware.

Applications and Use Cases of PXI-7851

The PXI-7851 R Series Multifunction RIO Module is a PXI-based R Series multifunction reconfigurable I/O (RIO) module that integrates analog input/output, digital I/O, counters, and a user-programmable FPGA. It is designed for custom measurement, real-time control, and deterministic processing, making it suitable for flexible and high-performance test and control systems.
