NI PXI-7852R

Technical Specifications: FPGA: Xilinx Virtex-5 LX50 Analog Input: Dedicated ADC per channel, maximum sampling rate 750 kS/s Digital I/O: 96 bidirectional digital lines, 3.3 V / 5 V logic compatible Maximum FPGA Clock Rate: 40 MHz Bus Type: PXI hybrid bus

Function Features: User programmable FPGA using LabVIEW FPGA module. Independent timing and triggering per analog channel. Supports multi-rate sampling and individual channel trigger. Onboard hardware-timed processing. Custom communication protocol implementation.

Application Scenarios: Hardware-in-the-loop simulation, custom protocol communication test, sensor simulation, high-speed control, power electronics test, real-time embedded validation.

Material Composition: Front panel: aluminum alloy. PCB: high density multi-layer FR4 board. FPGA chip, analog ADC circuits and digital level shifters.

Structural Features: 3U single-slot PXI module. Separate analog and digital power domains. PXI hybrid interface.

Working Principle: User compiled FPGA bitstream is loaded to onboard Virtex-5 FPGA. FPGA directly controls analog and digital I/O hardware, executes real-time processing and custom logic with hardware timing, independent of host operating system latency.

Installation Requirements: Install into 3U PXI hybrid chassis slot. Install LabVIEW FPGA module and RIO driver. Use shielded cables for analog and digital signals.

Usage Notes: FPGA logic must be compiled and downloaded before operation. Observe absolute maximum ratings of analog and digital I/O. Static protection required during handling. Thermal cooling must meet module power dissipation requirement.
