How to Control Spectral Leakage with Window Functions in LabOne

25.11.2021

Symmetric and asymmetric window functions

Spectral characterization of signals and systems is required in a broad range of applications in physics and engineering. Analyzing a signal in the frequency domain reveals valuable information about the signal behavior which is not necessarily obtainable from its time-domain analysis...

Choosing the Best Current Input Range for Impedance Measurements

20.10.2021

Current-zone-ranging

Auto-ranging is one of the key features of all impedance analyzers. It makes it possible to run a sweep (of frequency, AC amplitude, DC bias, or other parameters of interest) continuously and without manual adjustments of the input ranges. This helps particularly when working with reactive components, whose impedance changes...
