When creating designs, engineers must meet or exceed their objectives for instrumentation and measurement equipment. Having accurate and correct instruments for test and measurement methods and ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...

The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...

Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

BMW has patented a calibration method for an electrochemical impedance measuring device used to measure an electrochemical cell’s impedance. The method involves connecting the device to an impedance ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

In this interview, industry expert Jason Chonko shares practical strategies for overcoming common challenges in high-resistance and low-signal electrical measurements by addressing noise, grounding, ...
