A PCI Express digitizer provides 200 MS/s sampling rate of 14 bits of data across one channel. The PCIe-9842 from Adlink Technology 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 50Ω impedance. With this simplified front-end design and highly stable onboard reference, the PCIe-9842 provides not only high-accuracy measurement results but also delivers high-dynamic performance.

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 Mbyte/s rate to the host system memory. End-users will further benefit from a typical dynamic performance that 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. Current one list price is $3,000.
