PXIe-7915

The PXIe-7915 is a PXI FlexRIO Coprocessor Module from National Instruments, designed for FPGA-based signal processing, real-time algorithm execution, high-speed data streaming, and PXI Express automated test systems. The module features a Xilinx Kintex UltraScale KU060 FPGA, 4 GB DRAM, and an x8 Gen 3 PXI Express interface, making it suitable for applications that require substantial FPGA processing resources and high-bandwidth data movement inside a PXI chassis. NI lists the PXIe-7915 with part number 785174-01.

The NI PXIe-7915 helps engineers add powerful custom signal-processing capability to PXI Express systems. Its FPGA can be programmed using LabVIEW FPGA or Xilinx Vivado, allowing users to implement custom algorithms, filtering, triggering, data reduction, real-time processing, and application-specific logic directly in hardware. This makes the PXIe-7915 useful for test systems where large amounts of data need to be processed before being transferred to the host computer.

Using x8 Gen 3 PCI Express architecture and peer-to-peer streaming, the PXIe-7915 FlexRIO Coprocessor Module can stream data to and from other modules in a PXI chassis at up to 7 GB/s without relying on the host controller. This high-speed data path helps reduce transfer bottlenecks and improves system performance in applications that require real-time analysis, continuous streaming, or fast communication between PXI instruments.

The National Instruments PXIe-7915 can be paired with other PXI instruments, such as PXI Vector Signal Transceivers, digitizers, oscilloscopes, RF modules, signal generators, and other FPGA-based modules. By adding the PXIe-7915 to a PXI system, users can run complex algorithms in real time and expand the processing capability of the test platform. This makes the module suitable for RF signal processing, wireless communication validation, protocol analysis, hardware-in-the-loop testing, semiconductor test, and automated measurement acceleration.

The PXIe-7915 KU060 FPGA is ideal for RF and high-speed signal processing applications that require more FPGA resources than lower-end FlexRIO coprocessor modules. Compared with PXIe-7911 or PXIe-7912 configurations, the PXIe-7915 provides a stronger FPGA option for users who need higher logic capacity, onboard memory, and high-speed PXI Express connectivity. Its 4 GB DRAM supports buffering, data handling, and memory-based processing during high-speed acquisition or streaming tasks.

In system integration, the NI PXIe-7915 is designed for compatible PXI Express chassis and supports modular PXI architecture. It can be used in synchronized multi-instrument systems where timing, triggering, and high-speed data transfer are important. Because the FPGA can be reconfigured through software, the same hardware can be adapted for different test requirements, helping engineers reduce hardware changes when developing new measurement or validation systems.

The PXIe-7915 FlexRIO Coprocessor Module is suitable for research laboratories, production test systems, RF and wireless validation, radar and communication test, semiconductor test, signal intelligence, digital signal processing, and custom automated test platforms. It is especially useful when users need to offload computation from the host controller and perform real-time processing directly inside the PXI system.

Overall, the NI PXIe-7915 PXI FlexRIO Coprocessor Module is a high-performance FPGA-based processing module for PXI Express systems. With its Xilinx Kintex UltraScale KU060 FPGA, 4 GB DRAM, x8 Gen 3 PXI Express interface, LabVIEW FPGA and Xilinx Vivado support, and peer-to-peer streaming up to 7 GB/s, the PXIe-7915 is well suited for RF applications, real-time signal processing, high-speed data streaming, and advanced automated test applications.
