PCIe-9852
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, opti-
cal fiber testing and radar signal acquisition. Analog input with 90
MHz 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 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 cir-
cuit 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.
