ADLINK PXIe-9852 High Speed Digitizer Configuration Guide

In high-speed transient measurement fields such as distributed temperature sensing (DTS), laser radar (LiDAR) ranging, radar intermediate frequency acquisition, and power cable fault location, sampling rate and dynamic range are often contradictory. ADLINK PXIe-9852 is a 2-channel 14 bit 200 MS/s PXI Express high-speed digitizer that combines 90 MHz analog bandwidth, flexible input impedance (50 Ω/1M Ω), multi range (± 0.2V/± 2V/± 10V), and 1 GB onboard storage. It also provides a unique Data Average Mode, which can improve effective resolution through oversampling under re triggering conditions. This article is aimed at testing system engineers, providing a complete engineering deployment and optimization guide from the dimensions of hardware installation, front-end configuration, trigger source and mode (including pre trigger, medium trigger, and re trigger), data averaging mode principle, multi module synchronization (including pre-data-ready handshake), clock architecture (internal/external reference/sampling clock), and automatic calibration.
