  • Allows Variable Rate K-Clocking or Inactive External Clock with Digitizer
  • Simultaneously Digitize Interferometer Signal with Returned Optical Signal
  • Allows for Rejection of Rising Edges for Pulses Below Specified Amplitudes
  • Allows for Manual Clock Management for Pulses Occurring on Border Between K-Clock Activity & Inactivity by Returning Raw Data Sample #
  • Transparent to Standard Digitizer Drivers for Windows/Linux, Requiring no Special Software
  • C/C# SDK Provides Ready-Made Compiled Sample Programs

eXpert FPGA DSP Features for Data Acquisition

eXpert FPGA DSP Technology for Data Acquisition

GaGe provides several eXpert FPGA processing firmware options for use with CompuScope Digitizers allowing for some signal processing analysis, or other specific functionality, to be performed on the digitizer hardware itself within its onboard Field Programmable Gate Array (FPGA). These include:

PCIe Data Streaming

Stream acquired data directly through PCIe to host PC RAM and on to targeted host based CPUs or GPUs for analysis and/or to high-speed storage for real-time signal recordings.

Signal Averaging

Using rapid signal averaging, small signals can be extracted from a background of high amplitude noise, which may even be larger than the actual signal itself.

Fast Fourier Transform

Allows 8192 point FFT calculation analysis, with Real & Imaginary spectral components, directly on the digitizer and transfer of multiple Fourier Spectra to host PC in single PCIe transfer.

All GaGe eXpert FPGA features are supported with Software Development Kits (SDKs) that provide ready-made compiled sample programs illustrating how to configure and use the targeted feature with documentation for its use in custom developed applications.

GaGe can also develop customized firmware (e.g. DDC, FIR Filtering, Peak Detect, etc.) to meet specific customer application requirements. Please contact us with a summarized listing of application requirements to evaluate for design feasibility. Pricing for customized FPGA development is highly dependent on the scope of the project work and on expected product volume.
