Impedance measurement fft

Witryna5 kwi 2024 · To decompose the frequency spectrum, a FFT (512-point resolution) was applied, where the maximum power amplitude in the spectrum corresponds to the sensor measurement value (Figure 1f). Smart windowing, interpolation techniques, and precise time gating are mandatory for detection with good SNR. ≈900 µs were then required … WitrynaThe Zurich Instruments MFIA is a digital impedance analyzer and precision LCR meter that sets the new standard for impedance measurements in the frequency range from 1 mHz to 500 kHz (extended to 5 MHz when upgraded). The MFIA has a basic accuracy of 0.05% and operates over a measurement range spanning from 1 mΩ to 1 TΩ.
