Test and Measurement Tips
Why do alternators output sine waves?
You often hear it said that motors and generators are the same thing–put electrical power into a motor and it generates mechanical torque. Turn the shaft of an electric motor and it generates electrical power. This statement is true theoretically. But motors and generators have different architectures. So you might wonder why there’s a difference. […]
The difference between TDR and spread-spectrum TDR
Most engineers are probably familiar with the basic idea of time-domain reflectometry (TDR): The time-domain reflectometer sends a signal, frequently a square wave or stepped pulse, into the medium under investigation (typically a cable) with the far end of the cable shunted, open or left connected at the receiver. The instrument measures the time elapsed […]

Tester evaluates internal battery electrochemical and electrical properties
The BA8100 is designed to test batteries using a complex AC measurement technique known as electrochemical impedance spectroscopy (EIS). Through this technique, the BA8100 derives the internal impedance of a battery across a wide frequency sweep. The acquired data is used to display a graphical representation of electrochemical processes occurring within the battery. The BA8100 […]
The difference between electronic distortion and noise
The concepts of distortion and noise in signal processing overlap to a limited extent, but they are distinct phenomena. Distortion in a signal is the alteration or change of the shape or some other characteristic of the waveform. In contrast, noise is an external random signal added to the original signal. It’s harder to remove […]

Measuring ESR and ESL of dc-link capacitors
Impedance analyzers work better than LCR meters when it comes to sizing up the super-low impedance and inductance of modern power converter capacitors. Tim Ashworth, Meng Li, Zurich Instruments DC-link capacitors are often found in power conversion applications such as inverters, motor drives, medical power supply equipment, and so forth. Consequently, dc-link capacitors often need […]
