How to Test PCB Traces with a TDR

 


Precise trace validation is essential for ensuring clean signal paths in high-speed PCBs.Hidden impedance changes along traces can cause reflections and timing issues.How to test PCB traces with a TDR involves sending a fast rise-time step signal into the trace and analyzing reflected waveforms to locate discontinuities. Engineers can identify problems such as width variations, vias, stubs, or poor terminations with high accuracy. This method helps verify controlled impedance designs before full system integration. With advanced measurement expertise and practical validation techniques, Bitwise Laboratories supports reliable PCB performance and strong signal integrity in modern electronic systems.
