1 Introduction
The PXIe-69852 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 90MHz
bandwidth receives ±10V high speed signals with 50Ω 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 PXIe-69852 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 PXIe-69852 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.
