FSA Signal Processors for LDV Systems FSA4000-X

SKU: FSA4000-1

The FSA series of signal processors is the most accurate and fast, designed for LDV applications. 


Product Details

TSI’s Flow and Size Analyzer sets the standard in digital signal processing. Firmware-based, it is the fastest, most accurate signal processor ever offered for LDV applications. This compact device is available in two versions: the FSA 4000 and the FSA 3500. Both versions are high-performance digital burst processors offering a host of useful features to optimize data collection.

Features & Benefits

  • High accuracy based on a combination of SNR-based burst detection, dynamic burst sampling rate selection, multi-bit sampling, and other techniques to maximize measurement resolution and accuracy
  • High doppler frequency – up to 175 MHz – is ideal for measurements in supersonic flows, turbulence research, hydrodynamic research, and more
  • Dynamic burst centering, a concept developed by TSI, allows the system to capture samples from the best segment (the middle portion) of each burst 
  • Optimized accuracy even from poor quality signals through the use of patented processing techniques
  • Fully controlled by the FlowSizer™ Data Acquisition Analysis and Display Software
