Multiplexed Impedance Measurements with the MFIA

on 17.06.2020 at 13:43 by Meng on Blog of Meng Li
Introduction Having more impedance measurement channels is often desirable in many applications. For instance, in electrical impedance tomography (EIT), it is common to have many channels to achieve enough spatial resolution (144 electrodes on the thorax) [1]. Naturally, this can […]

Automated 2D Impedance Sweep on the MFIA

on 28.08.2019 at 15:43 by Meng on Blog of Meng Li
Many devices and materials exhibit an impedance which depends on both frequency and other parameters such as bias voltage. To fully characterize the impedance of these samples requires an impedance analyzer with the ability to sweep in two dimensions. The MFIA (and MFLI with MF-IA option) can be easily controlled via any of the five included APIs to open up the full parameter space of impedance analysis.This blog details a short script for Python 3.7 which demonstrates the ease in which multi-dimension impedance sweeps can be carried out.
