PXIe-7867 Multifunction Reconfigurable I/O Module 18AO/6AI (785570-01)

PXIe, Kintex-7 160T FPGA, 18-Channel AO, 1 MS/s, PXI Multifunction Reconfigurable I/O Module
The PXIe-7867 features a user-programmable FPGA for high-performance onboard processing and direct control over I/O signals for complete flexibility of timing and synchronization. With 18 analog output channels connected directly to the FPGA, you can quickly design for applications that require precise timing such as hardware-in-the-loop testing, custom protocol communication, sensor simulation, and high-speed control. The PXIe-7867 features a dedicated A/D converter (ADC) per channel for independent timing and triggering. This design offers multirate sampling and individual channel triggering, which are outside the capabilities of typical data acquisition hardware. The PXIe-7867 also includes peer-to-peer streaming for direct data transfer to other PXI Express modules.
