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 […]
Exceeding 100 Gbps with a sub-terahertz 6G testbed
Here’s a look at testing necessary for super-high throughputs involved in the emerging area of 6G. Greg Jue, Keysight Technologies 6G research is in its early stages. The vision for what the International Telecommunication Union calls Network 2030 continues to take shape. While the industry is years away from starting the standards development process, subterahertz […]
Applying PC-based test & measurement instruments
For some features, PC-based scopes sport higher performance than similar benchtop instruments. Trevor Smith, Pico Technology The debugging and validation of electronic systems calls for versatile instruments with wide-ranging functions and easy programmability. An engineer working on high-speed logic signals one day might be called upon to run a long-duration soak test the following day […]
