Description
The National Instruments PXIe-7820 PXI Digital Reconfigurable I/O Module is a sophisticated system element designed for versatility and high performance in automated test equipment and control systems. This module, bearing the part number 200709A-01, falls under the PXI R Series category and is known by its model number, PXIe-7820.
It is characterized by its notable feature – the Kintex 7 160T FPGA, which provides the backbone for its reconfigurability and high-speed processing capabilities. The module boasts a substantial 128 Digital I/O (DIO) channels, allowing for significant flexibility in interfacing with various digital devices and sensors. Furthermore, it supports peer-to-peer streaming, enhancing its capacity for fast data transfer between modules without involving the host processor, thus reducing system latency and increasing throughput.
The PXIe-7820 is programmable by the client with LabVIEW FPGA, offering a user-friendly environment for developing custom applications tailored to specific needs. This feature is particularly beneficial for applications such as rapid waveform generation, sensor simulation, hardware-in-the-loop (HIL) testing, custom communication protocols, and bit error range testing.
Additional technical specifications include direction control per digital I/O channel, allowing for precise control over signal direction on a per-channel basis. The module can handle a minimum I/O pulse width of 6.25 ns and a minimum testing period of 5 ns, indicating its capability to operate at high frequencies. The support for an external clock direction input further enhances its versatility in synchronization with external devices. Lastly, it maintains a maximum input leakage of ± 15 μA, ensuring signal integrity and reducing the risk of damage to connected devices.
