Principle of Impedance Analyzer
Based on RF-IV measurement and circuit matching evaluation. Impedance (Z) is a physical quantity characterizing the opposition to current in an alternating electric field, reflecting the comprehensive response of materials or circuits to alternating current, including the combined effects of resistance (R), capacitive reactance (XC), and inductive reactance (XL).
