How to Test PCB Traces with a TDR – Bitwise Laboratories

 

How to test PCB traces with a TDR involves using a Time-Domain Reflectometer (TDR) to analyze signal integrity and detect issues like impedance mismatches, short circuits, or broken traces. A TDR sends an electrical pulse through the PCB trace and measures reflections to identify discontinuities. To perform the test, connect the TDR probe to one end of the trace and observe the reflected signal on an oscilloscope. Impedance changes indicate potential defects. Proper calibration ensures precise measurements. For accurate and efficient PCB trace testing, Bitwise Laboratories offers advanced TDR solutions, helping engineers optimize high-speed circuit designs and maintain signal integrity in complex electronic systems.
