This article summarizes the importance of the PCB impedance design. Based on this, it elaborates high-precision adjustable TDR probe which tests PCB impedance goal and production principles. Adjustable probe and ifxed probe are done in the test with contrasts by MSA test veriifcation and test comparison for the same type of adjustable probe from abroad with analytical performance. It indicates the adjustable probe to meet the measurement requirements of the PCB real impedance line.
