ADLINK Debuts 2-Channel 200-MS/s 14-Bit PCI Express Digitizer

June 20, 2013. ADLINK Technology Inc. announced the release of its new high-speed PCI Express digitizer, the PCIe-9852, featuring two simultaneously sampled 200-MS/s input channels with 14-bit resolution, 90-MHz bandwidth, and up to 1-GB DDR3 onboard memory. Accurate measurement, up to 800-MB/s data streaming, and onboard signal-averaging technology combine to make the PCIe-9852 suitable for long-term, high-speed data-recording applications such as distributed temperature sensing, radar signal testing, and atmospheric science research.

“ADLINK’s PCIe-9852 benefits distributed temperature sensing (DTS) applications by enabling significantly increased accuracy in temperature measurement,” stated Catherine Wu, product director of ADLINK's Measurement and Automation Product Segment. “The PCIe-9852’s two analog inputs simultaneously receive both Stokes and anti-Stokes lines generated in the application, as well as increased high resolution sampling rates meeting requirements for sensing distances of 30 km and more. In addition, onboard signal averaging technology isolates even minor data detected from crowded environments.”

The PCIe-9852 provides 14-bit high resolution ADC and up to 200-MS/s sampling, delivering 83 dB SFDR, 62 dB SNR, and -81 dB THD. The PCIe-9852 provides a flexible set of input ranges, ±0.2V, ±2V, or ±10V, software selectable 50-Ω or 1-MΩ input impedance, and a variety of triggering options and tight synchronization capability.

Based on Gen 2 PCI Express technology, the PCIe-9852 streams data on both channels at maximum data rate (200 MS/s), enabling continuous delivery to the host PC at rates up to 800 MB/s, and a complementary 8 x 500 GB driver RAID system (4 TB) further extends capture sessions beyond one hour. The PCIe-9852 combines high-bandwidth, dual-channel, simultaneous data streaming and built-in memory up to 1 GB for massive data storage, making it ideal for real-time, high-speed data recording.

The PCIe-9852 is equipped with onboard signal averaging technology, allowing detection of small repetitive signals in noisy environments, with no CPU loading, suitable for applications requiring extraction of small signals from background noise, as occurs in DTS.

The ADLINK PCIe-9852 supports multiple operating systems, including Windows 8, Windows 7, Windows XP, and Linux, and is fully compatible with third-party software such as LabVIEW and MATLAB. Users can simply complete the programming through ADLINK DAQPilot software development kit.
