| Abstract: | Based on IEC 60318--1 Standard, a measurement system for this parameter is designed and realized automatically. The system can measure the impedance from 100 Hz - 10 kHz in 1/N octave frequency and it has the characteristics of speediness, high - efficiency, easy - operation, etc. The measurement results show that the system can satisfy the international standard and provide calibration service for the manufacturer and the end user. |
