FPGA Digital Signal Processing
 | GaGe provides several eXpert FPGA processing firmware options for use with CompuScope Digitizers. All standard default CompuScope Digitizer model configurations can store raw acquired waveform data to onboard sample memory and then transfer them quickly to the user for analysis, display and/or storage. The addition of optional eXpert FPGA processing firmware features allow 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). |
Unlock ultra-fast, real-time signal intelligence with GaGe’s FPGA Digital Signal Processing (DSP) solutions—designed to revolutionize how engineers, scientists, and developers capture, analyze, and interpret complex waveform data. Whether you’re pushing the boundaries of aerospace, medical imaging, radar testing, or spectrum monitoring, these onboard FPGA DSP firmware options eliminate bottlenecks and supercharge your system performance with precision and speed that conventional processing can’t match.
Engineered to run directly on GaGe’s CompuScope Digitizers, eXpert FPGA DSP firmware delivers immediate signal analysis without bogging down your host PC. You gain full-speed sampling, smarter data flow, and hands-off automation—allowing your team to do more, faster, and with greater accuracy.
