Order-No.: 250-181-000   Series/Model: eXpert / Finite Impuls Response (FIR)

Main Product Features

• Allows Processing by an FIR Filter with up to 20 Taps;
  Can be Extended in Software to up to 39 Symmetric Taps
• FIR Filter Coefficients can be Tailored to Emphasize
  Signal Pulses of a Specific Shape
• FIR Filtering is Performed by GaGe Digitizer Hardware,
  Allowing the Host-PC to Handle Other Tasks in Parallel
• Data is Filtered During Transfer to the PC, so that the
  Repetitive Signal Capture Rate of the Digitizer is not Reduced
• FIR Filter Algorithm Covers a Wide Range of Common Numerical
  Filters such as Moving Average Filters & Gaussian Filters
• Transparent to GaGe's Standard CompuScope Digitizer Drivers
  for Windows, so that no Special Software is Required
• Compatible with CompuScope Digitizer Software Development Kits (SDKs) for C/C#, LabVIEW, & MATLAB

The onboard FIR Filtering eXpert FPGA DSP feature is a powerful method for removing unwanted signal features (like noise) and emphasizing signal features of interest.

Traditional analog filters are usually limited to rather simple filtering methods, such as low-pass filtering, high-pass filtering and band-pass filtering. Numerical filtering of digitized waveform data, available on GaGe high-performance digitizers, allows much more complex filtering methods such as Moving Average Filters and Gaussian Filters to be implemented.

Applications

• Ultrasonic testing
• laser spectroscopy
• Lidar systems
• Fiber optics tests
