Frequency Response Analyzer
Frequency Response Analyzer
FRA51615

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


Gain-phase measurement
ball
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.

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.

 

 

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