The PCIe-9842 is a PCI Express digitizer from Adlink Technology Inc. which provides a 200 MS/s sampling rate of 14 bits of data across one channel.
The PCIe-9842 is designed for applications such as light detection and ranging (LIDAR) tests, optical fiber tests, and radar signal acquisition. Its 100 MHz bandwidth analog input is designed to receive ±1V high-speed signals with 50 Ω impedance.
For applications that require data to be acquired and transferred in real-time, the PCIe-9842 is designed on the PCI Express x4 bus interface to provide adequate bandwidth for real-time transfers. As the signal is converted from analog to digital, the data will be transferred directly and continuously at a sustained 400 MB/s rate to the host system memory.
Typical dynamic performance includes a 11.3 effective number of bits (ENOBs) and a 70 dB signal-to-noise ratio (SNR) with an input frequency of a 10 MHz sine wave.
ADLINK not only provides legacy drivers for users to develop using Microsoft C++ and Visual Basic, but also a task-oriented driver (DAQPilot) to accelerate the development cycle. Express VIs and Polymorphic Vis for the PCIe-9842 also provide a quick and simple way to operate the digitizer in LabVIEW.
