200 MS/s 14-Bit 1-CH High-Speed PCI Express Digitizer
The ADLINK PCIe-9842 is a 200 MS/s 14-bit 1-CH digitizer designed for applications such as LIDAR testing,
optical fiber testing, and radar signal acquisition. The 100 MHz bandwidth analog input with 50 ohm impedance is
designed to receive ±1 V high speed signal. With this simplified front-end design and high 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 utilizes the PCI
Express x4 bus as its interface. When signals are converted from analog to digital data, the data will be transferred
to host system memory continuously because of the high bandwidth of the PCI Express.
