Witryna11 kwi 2024 · Rescaling oscilloscope signals and de-embedding cables. An oscilloscope measures the voltage that is applied to its input terminals. In most cases that works fine but, in some instances, it is necessary to move the measurement plane of reference and calibrate the oscilloscope’s measurements. For instance, if a minimum loss … 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.
WitrynaElectrochemical impedance is usually measured by applying an AC potential to an electrochemical cell and then measuring the current through the cell. Assume that we apply a sinusoidal potential excitation. The response to this potential is an AC current signal. This current signal can be analyzed as a sum of sinusoidal functions (a Fourier … WitrynaFFT & DFT（任何大小），和Nth倍频程分析率 ...
