Portable, lab quality, dynamic signal analyzer seamlessly integrated with MATLAB


  • Fully alias-protected two or four-channel dynamic signal analysis systems
  • 90 dB spurious free dynamic range (SFDR) over dc to 50 kHz measurement bandwidths
  • Expandable from two to sixteen channels
  • A comprehensive set of signal and system analysis instruments coded in MATLAB
  • On-board, real-time signal processing
  • Integrated multifunction signal generation


SigLab (model 50-21) enables sophisticated measurements such as time histories up to 15 M samples long, 128K samples per second on each channel, and power spectrum with guaranteed 95 dB spurious free dynamic range.

In addition, SigLab perfoms measurements including: transfer function magnitude, phase, and coherence using broad band FFT techniques or swept sine, auto and cross correlation, impulse response, system modeling in either Z (discrete time) or S (continuous time) domains, harmonic distortion versus amplitude and frequency, 1/nth octave audio analysis, and spectral maps and waterfall plots for non-stationary spectrum analysis.

These measurements are all performed directly in the MATLAB environment, making them available for custom post-processing using MATLAB and Simulink, or comparison with theoretical performance targets.

SigLab is delivered as a complete system. Spectral Dynamics provides all the needed MathWorks products with this system.
