Equivalent
circuit analysis
1. Circuit model
Equivalent circuit models for circuit element components
3-element models: 4 types; 4-element models: 1 type
See “4.9 Equivalent Circuit Analysis Function” (p. 124).
2. Circuit model selection method
AUTO (automatic selection), HOLD (fixed)
3. Measurement items
3-element model
L1 (inductance), C1 (capacitance), R1 (resistance), Qm (sharpness of resonance),
and sum of squares of residual error between observed values and ideal frequency
characteristics
4-element models
L1 (inductance), C1 (capacitance), R1 (resistance), C0 (parallel capacitance), Qm
(sharpness of resonance [mechanical quality factor]), K (electromechanical coupling
coefficient), and sum of squares of residual error between observed values and ideal
frequency characteristics
4. Equivalent circuit analysis execution
AUTO (executed after frequency sweep operation is completed) and MANU (executed at
user-specified timing)
5. Limitation on the sweep range used in equivalent circuit analysis
Normal sweep Analysis is performed in the sweep range defined by the analysis
start frequency and the analysis stop frequency.
Segment sweep Analysis is performed using the sweep range for the set segment
No.
6. Comparator
Implement comparator for analysis result
L1, C1, R1, C0, Qm: HI/IN/LO and absolute value setting
7. Resonance Frequency
The frequency (resonance frequency or antiresonance frequency) at which the
measurement value for the following measuring items is the local maximum or local
minimum can be retrieved by communication.
Z (impedance), G (conductance), B (susceptance) and Rs (equivalent series resistance)
