Displaying Nyquist Plots on the MFIA Impedance Analyzer

on 27.09.2017 at 13:45 by Tim Ashworth
A short guide to displaying impedance data as Nyquist plots on the LabOne Sweeper of the MFIA. Nyquist plots are a key tool when displaying complex impedance data. They display the real part of the signal on the X-axis against […]

LCR Meter vs Impedance Analyzer

on 11.08.2017 at 14:52 by Tim Ashworth
We are often asked about the difference between LCR Meters and Impedance Analyzers, especially since the MFIA offers the functionality of both instruments. LCR-meters and impedance analyzers are fundamentally similar, in that they both measure impedance parameters such as capacitance, […]

Teraohm Impedance measurements with the MFIA Impedance Analyzer

on 29.05.2017 at 11:45 by Tim Ashworth
Introduction This blog post describes impedance measurements of a 1 TΩ commercially-available resistor using the MFIA impedance Analyzer. This further demonstrates the performance of the MFIA to accurately measure challenging components with very high impedance.  Thanks to a clear reactance […]

Characterizing High-Q 100 pF Capacitors with the Zurich Instruments MFIA

on 30.01.2017 at 09:30 by Tim Ashworth
Introduction In the last impedance blog post we discussed how the MFIA could be used to investigate 3000 F capacitors, here we turn to the other end of the spectrum to investigate 100 pF capacitors. Specifically, this blog post looks at […]

Using the MFIA Impedance Analyzer to characterize the ESR of a Super-capacitor

on 01.11.2016 at 10:14 by Tim Ashworth
Introduction Super-capacitors are very useful devices providing power for applications ranging from SRAM to high-speed trains. The energy density is 10 – 100 times higher than that of standard (electrolytic) capacitors. And although they have a lower energy density than […]
