TDR – Step Responses

Take advantage of both TDR and TDT (Time Domain Transmissometry) for effective signal analysis. Our multi-channel TDR systems support a broad range of applications with precision and flexibility.

What are TDR/TDT step responses used for?

  • Detect discontinuities — down to millimeter resolution in some systems
  • Identify open circuits (disconnections) and short circuits
  • Assess signal integrity across connectors, traces, and interposers
  • Evaluate PCB vias — signal transitions and impedance mismatches
  • Measure signal attenuation along transmission paths
  • Compare DUT behavior before and after testing
  • Analyze crosstalk between adjacent lines
  • Measure trace length and timing skew
  • Characterize the dielectric properties of materials
