Applications For all kinds of frequency response measurement including servo characteristics

Servo characteristics measurement of magnetic disk and photo disk

This is transfer function measurement related servo , controlling the pick-up\ of magnetic disk/ photo disk. It measures open loop characteristics under normal performance. It can also measure the phase of high gain area in stabilized condition because of its higher noise eliminating capacity, with measurement in dynamic range of more than 140dB using auto ranging operation at every measuring frequency.


Impedance measurement for piezo-electric element
This measures the electric resonance characteristics of piezo electric element such as used for piezo-electric actuator etc.
FRA can provide frequency resolution precisely of specified frequency range, different from FFT, and then the detailed characteristics of resonance area are known because of high phase accuracy ,¡Ó0.3¢X.
By combination with power amplifier ,large amplitude can also be measured, not only small amplitude.



Loop response measurement of switching power supply
For evaluating the dynamic stability of switching power supply.
As both of signal source and measured terminal are isolated, even DC area which is added can be freely connected. It also can measure the effect of phase compensation circuit clearly.



Internal resistor measurement for electric double layer condenser

This is internal resistor measurement of electric which is located between condenser and battery. FRA can measure with max.0.1mHz resolution, and then Faraday impedance analysis is also possible to be executed by Cole-Cole Plot (complex impedance display).
Furthermore it is possible to measure with switching charge and discharge under large current because of strong protection from disturbance.
