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 powerful 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 such as optical fiber testing.
Often, when measuring analog signals, captured data carries unwanted random additional content, caused by surrounding disturbances or observation errors, with most manifesting as random noise. Averaging is a simple and effective way to get rid of random noise in data which is periodic or repeating.
The PCIe-9852 performs signal averaging onboard, achieved using an FPGA (field-programmable gate array), relieving the system host of any signal averaging duties. Signal averaging is accomplished much faster than on the host, with no usage whatever of the host¡¦s CPU.
Data Streaming Up to 800MB/s
Based on PCI Express Gen2 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
Using an 8 x 500 GB driver RAID system (4TB) extends capture sessions beyond one hour
PCIe-9852 provides a dedicated connector for system synchronization interface (SSI), enabling multiple module synchronization, to extend the quantity of analog inputs within one system.
Application: Distributed Temperature Sensing (DTS)
ADLINK'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.
