Inductance of an SMD Shunt Resistor measured with the MFIA

on 15.09.2020 at 10:32 by Tim Ashworth
The reliable and accurate measurement of current is critical to optimising any electronic system. The most commonly used method to measure current flows within a circuit is by using a low-value resistor mounted in series, and then measuring the voltage […]

Webinar Q&A- Impedance Analysis; Measuring Fast and Low

on 23.06.2020 at 08:01 by Tim Ashworth
This blog post answers the many welcome questions from the audience during the recent webinar “Impedance Analysis; Measuring Fast and Low”. This webinar covered two distinct and equally important impedance measurement challenges. The first involves measuring the low equivalent series […]

DC I-V Sweeps on the MFIA

on 10.01.2020 at 09:07 by Tim Ashworth
Characterizing the impedance of components and materials with the MFIA is done by necessity with an AC signal. However, the MFIA and MFLI can also take DC measurements. This blog post shows how easy it is to take DC measurements, […]

Bioimpedance of a Muscle Contraction with the MFIA

on 22.11.2019 at 09:20 by Tim Ashworth
Impedance measurements of biological tissue are commonly used in bio-engineering and life sciences to assess the condition and composition of tissue in a non-invasive, reproducible way.  In addition, bio-impedance measurements, also known as bioelectrical impedance analysis (BIA) or electrical impedance […]

Reloading Data into LabOne Modules

on 29.08.2019 at 12:48 by Tim Ashworth
LabOne now supports reloading data into the LabOne Modules when using the HDF5 file format. Starting from LabOne 19.05, data acquired in modules such as the Sweeper, DAQ, Scope and Spectrum Analyzer, can now be reloaded into the same LabOne […]

What is the Basic Accuracy of an Impedance Analyzer?

on 29.08.2019 at 11:09 by Tim Ashworth
This blog explains the meaning of basic accuracy when referring to impedance analyzers. The accuracy of an impedance analyzer is a critical parameter that allows the user to know how close the measured impedance will be to the true impedance […]

Measuring low ESL and low ESR of a DC-Link Capacitor with the MFIA Impedance Analyzer

on 10.06.2019 at 09:25 by Tim Ashworth
Introduction: This blog post describes how the MFIA (and MFLI with MF-IA option), can characterize the equivalent series inductance (ESL) and equivalent series resistance (ESR) of a DC-Link capacitor typically used in power inverters for electric vehicles. The ESR and […]

Gated data transfer for increased data sampling rate on the MFIA and MFLI

on 19.12.2018 at 14:42 by Tim Ashworth
Introduction For measurements of signals which are rapidly changing, for example, when measuring capacitance transients in Deep Level Transient Spectroscopy (DLTS), high temporal resolution is required. In its standard operating configuration, the MFIA (or MFLI with MF-IA option) can sample […]

Square pulses for DLTS measurements on the MFIA

on 22.08.2018 at 16:00 by Tim Ashworth
Producing square voltage pulses and capturing capacitance transients This blog post shows how to produce square voltage pulses and capture the resulting capacitance transients on a short timescale (20 us) for example, for Deep-level Transient Spectroscopy (DLTS) measurements. Using the LabOne Threshold Unit […]

Rapid and Accurate C-V Measurements on the MFIA

on 19.08.2018 at 15:50 by Tim Ashworth
Fast C-V measurements up to 3000 V/s This blog post demonstrates the ability of the MFIA (also MFLI with MF-IA option) to measure capacitance on a short timescale (20 us) as a function of DC bias voltage, for example, for […]
