IConnect TDR software uses an impedance deconvolution (Z-line) algorithm, which, unlike the impedance computation feature in TDR oscilloscopes, takes care of multiple reflections and other accuracy issues in the TDR measurement and produces the True Impedance Profile. As a result, you can measure PCB trace impedance more accurately and improve correlation of your data between measurements, even the correlation between such measurements performed by your co-workers or customers in another part of the world True Impedance Profile produced by IConnect TDR software allows you to improve not only the TDR oscilloscope impedance measurement accuracy, but also increase the TDR oscilloscope resolution.
