1 Introduction

The PCIe-9852 is a high-speed 2-CH 14-Bit 200 MS/s digitizer, specifically designed for applications such as LIDAR testing, opti­cal fiber testing and radar signal acquisition. Analog input with 90 MHz bandwidth receives ±10V high speed signals with 50 impedance, and a simplified front-end design and highly stable onboard reference provide both highly accurate measurement results and high dynamic performance.
Ideal for environments requiring real-time acquisition and transfer of data, the PCIe-9852 is based on the PCI Express Gen 2 x4 bus as interface. When signals are converted from analog to digital, continual data transfer to host system memory is enabled by PCI Express high bandwidth capability.
The PCIe-9852 is auto-calibrated with an onboard reference cir­cuit calibrating offset and acquiring analog input errors. Following auto-calibration, the calibration constant is stored in EEPROM, such that these values can be loaded and used as needed by the board. There is no requirement to calibrate the module manually.
