Impedance measurement

	Measurement of resonance characteristics of piezo element
	Measurement of characteristics of multi-layer ceramic capacitor to which voltage is applied
	Measurement of internal impedance of battery cell

Gain-phase measurement

	Loop gain measurement of DC-DC converter

By measuring the loop gain characteristic of the DC - DC converter under the actual voltage applied to, We quantitatively evaluate circuit stability from phase margin and gain margin.


	Conditions
	Load: DC-DC converter with switching frequency 1MHz Sweep frequency 100Hz to 1MHz, Insertion resistor 51 ohm

	Results
	•	Phase margin, gain margin.
		The larger the margin, the more ringing and oscillation can be suppressed.

	•	Crossover frequency
		It is a guide of responsiveness at load fluctuation.

With marker search function, phase margin and gain margin can be detected automatically.
