5.10 Equivalent Circuit Analysis Function
238
The optional IM9000 Equivalent Circuit Analysis Firmware is required in order to use the equivalent circuit
analysis function. You can verify whether the IM9000 is installed on the Version Confirmation screen.
See "8.2 Checking the Version of the Instrument" (p. 306)
The equivalent circuit analysis function estimates equivalent circuit constants based on measurement results.
The IM3570 can estimate 3-element model and 4-element model constants as illustrated below. By using the
simulation function, you can display frequency characteristic ideal values using estimation results or user-con-
figured constants.
By using the comparator function, you can judge whether estimation results fall inside the judgment area.
*Typical frequency characteristics graphs
For models A through D, the horizontal axis is logarithmic, the vertical axis (Z) is logarithmic, and

is linear.
For model E, the horizontal axis is linear or logarithmic, the vertical axis (Z) is logarithmic, and

is linear.
