Description
The Part Number 784146-01 refers to a PXI R Series module, specifically the model PXIe-7857R. This module is described as an R Series Multifunction device, equipped with a Kintex-7 160T FPGA and 512 MB of DRAM, designed for versatile applications in automated test and measurement systems.
It features 8 Analog Inputs (AI) and 8 Analog Outputs (AO), both capable of operating at 1 MS/s per channel. Additionally, it provides a substantial number of Digital Inputs/Outputs (DIO), totaling 48, which allows for flexible interfacing with a wide range of digital devices.
The onboard FPGA, a Kintex-7 160T, offers high processing power for custom applications, while the 512 MB DRAM ensures ample memory for data-intensive operations. The module utilizes a Successive Approximation Register (SAR) ADC for analog-to-digital conversion, ensuring precise data acquisition.
With multiple, software-selectable input modes, the PXIe-7857R provides versatility in signal measurement. Its input impedance in the powered-on state is 1.25 GΩ paralleled with 2 pF, and in the powered-off state, it maintains a minimum input impedance of 4 kΩ. The output voltage range of ±10 V, combined with a 16-bit resolution, guarantees high fidelity in signal generation and measurement.
