Product Description

The NI PXI-7953R is a PXI FPGA module for the NI FlexRIO platform. It’s a key component in a modular, software-defined instrument, providing a user-programmable FPGA with a high-bandwidth connection to a FlexRIO adapter module. This combination allows you to create custom, reconfigurable instruments for high-performance measurement and control applications.

Product Specifications

The PXI-7953R is primarily defined by the resources of its Field-Programmable Gate Array (FPGA) and its interface.

• Bus Interface: PXI Hybrid-compatible, meaning it can be used in both PXI and PXI Express hybrid slots.
• FPGA: Xilinx Virtex-5 LX85 FPGA, which includes:
  • Logic Cells (LUTs): 51,840
  • DSP Slices: 48
  • Block RAM: 3,456 kbits
  • FPGA Slices: 12,960
• Memory: 128 MB of onboard Dynamic RAM (DRAM).
• I/O: The module features a high-density connector for a FlexRIO adapter module, providing 132 single-ended I/O lines, which can be configured as 66 differential pairs.
• Software Support: Designed for use with NI’s LabVIEW FPGA Module, which allows for graphical programming of the FPGA.

Product Advantages

• Flexibility and Customization: The PXI-7953R, when paired with a FlexRIO adapter module, allows you to create a completely custom instrument. You can program the FPGA to implement your own signal processing algorithms, custom triggers, or specialized control logic, giving you a level of flexibility that standard instruments don’t offer.
• High-Performance I/O: The FlexRIO platform is designed for high-speed, high-bandwidth applications. The adapter modules offer I/O capabilities for a variety of signals, including high-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), up to 1 Gbps digital I/O, and RF I/O up to 4.4 GHz.
• PXI Platform Integration: As a PXI module, the PXI-7953R benefits from the PXI platform’s robust infrastructure, including integrated timing, synchronization, and cooling. This is crucial for building multi-module, synchronized test and measurement systems.
• Real-Time Processing: The onboard FPGA allows for real-time signal processing and decision-making at hardware speeds, offloading these tasks from the host processor and enabling ultra-low-latency applications.

Product Applications

The PXI-7953R is a powerful tool for a wide range of demanding applications.

• Aerospace and Defense: Used for signal intelligence, radar signal processing, and hardware-in-the-loop (HIL) simulation.
• Telecommunications: Ideal for prototyping and testing high-speed communication protocols, as well as for real-time spectral analysis.
• Scientific Research: Employed in applications that require high-speed data acquisition and custom signal processing, such as in physics or advanced materials science.
• Semiconductor Test: Can be used to create custom digital protocols and high-speed test routines for semiconductor devices.

Precautions

To ensure proper and safe operation of the PXI-7953R, keep the following in mind:

• ESD (Electrostatic Discharge) Precautions: The module contains sensitive electronic components that can be damaged by static electricity. Always handle the module in a static-safe environment and use a grounded wrist strap.
• Chassis Compatibility: The PXI-7953R is a hybrid-slot-compatible module, but it must be installed in a PXI chassis with an adequate power supply and cooling capacity. Refer to your chassis documentation for details.
• Not Hot-Swappable: You must power down the PXI chassis before installing or removing the PXI-7953R or any FlexRIO adapter modules. Hot-swapping can damage the hardware.
• Software Installation: Always install the necessary software, including LabVIEW and the LabVIEW FPGA Module, before installing the hardware to ensure the system recognizes the device correctly.
