IM9000 – Equivalent Circuit Analysis Firmware


Hioki LCR Meters and Impedance Analyzers range from 1mHz to 3GHz devices to suit a wide range of applications in the testing of electronic components. The IM9000 is a optional firmware upgrade for Model IM3570 to facilitate Cole-Cole plots, simple circuit analysis and detailed acceptance/rejection decisions, adding value to the IM3570 to serve more advanced component analysis.

Key Features

  • The IM9000 can automatically select the equivalent circuit model from the five typical models to minimize the differences between the measured values and the ideal frequency characteristics derived from the analysis results
  • An acceptance/rejection decision can be made for the L, C, and R elements comprising a part and the resonance sharpness (mechanical quality coefficient)
  • A detailed decision can be made on the elements using the resonance of a piezoelectric element or inductor
