5.10 Equivalent Circuit Analysis Function
254
When performing analysis using the B and C models, it is necessary to measure frequencies that are as low
as possible, but low-frequency measurement is time-consuming. The IM3570 uses measured values for the
lowest frequency in the measurement range. By setting a low frequency for one point in the sweep range, it is
possible to conduct a precise analysis in a short period of time.
The following diagram provides an example of a B mode analysis performed using sweep measurement start-
ing at 100 kHz.
In this case, the sweep range setting should specify measurement of just one low frequency.

Example of an improper analysis
Looking at the analysis results, the negative
R value indicates that the analysis has not
been performed properly.
