The Tech Square PCIe-9852 is a 2-CH 14-bit 200 MS/s digitizer for high frequency and wide dynamic range signals with an input frequency up to 90 MHz. The 90 MHz bandwidth analog input with 50Ω impedance is designed to receive ±0.2 V, ±2 V, or ±10 V high-speed signals. With a PCI Express bus interface and ample onboard acquisition memory of up to 1 GB, the PCIe-9852 easily manages simultaneous 2-CH data streaming. With high speed and high linearity 14-bit A/D converters and high stable onboard reference, the PCIe-9852 provides both high accuracy and high dynamic performance, making it ideal for applications requiring high-speed data acquisition, such as optical fiber and LIDAR testing, and video signal analysis.


Dynamic Performance

  • Sampling rates up to 200 MS/s, delivering 83 dB SFDR, 62 dB SNR and -81 dB THD
  • 14-bit high-resolution ADC
  • Software-selectable 50Ω or 1MΩ input impedance, input range ±0.2V, ±2V, or ±10

    On-board Signal Averaging Technology
    The PCIe-9852 is equipped with onboard Signal Averaging Technology, allowing the detection of small repetitive signals in noisy environments, with no CPU loading, suitable for applications requiring extraction of small signals from background noise such as optical fiber testing.

    Data Streaming Up to 800MB/s

  • Based on PCI Express Gen2 technology, the PCIe-9852 streams data on both channels at the maximum data rate (200 MS/s), enabling continuous delivery to the host PC at rates up to 800 MB/s
  • Using an 8 x 500 GB driver RAID system (4TB) extends capture sessions beyond one hour

    Multi-Module Synchronization
    PCIe-9852 provides a dedicated connector for system synchronization interface (SSI), enabling multiple module synchronization, to extend the number of analog inputs within one system.


Application: Distributed Temperature Sensing (DTS)
Tech Square’s PCIe-9852 benefits Distributed Temperature Sensing (DTS) applications, by enabling significantly increased accuracy in temperature measurement. The PCIe-9852″s two analog inputs simultaneously receive both Stokes and anti-Stokes lines generated in the application, and increased high-resolution sampling rates meeting requirements for sensing distances of 30 km and more. In addition, onboard signal averaging technology isolates even minor detected data from crowded environments.

Benefits of Digitizers for this application

  • Two simultaneously analog inputs to receive Stokes line and anti-Stokes line
  • High sampling rate with high resolution gathering accurate temperature data to meet the requirement of long-distance (>30km) sensing
