Back in olden days, parallel buses were used to link electronic building blocks. Today serial buses have largely replaced them. There are numerous components for many applications that have standard serial interfaces, and this trend makes serial technology a good choice for design engineers. Because there are fewer signal lines, serial bus electronics take up […]
by Anil Pandey, Principal R & D Engineer, Keysight Technologies, and EDAboard.com forum member Antenna modeling in smartphone devices, using electromagnetic simulation software, has improved significantly by allowing the simulation of the antenna behavior in complex environments surrounding the antenna. Thus, current electromagnetic software allows the simulation of handheld antennas regarding not only the human presence (such […]
What is a harmonic? A harmonic of a repeating wave is a wave with a frequency that is a positive integer multiple of the original, known as the fundamental frequency. The original wave is also called the first harmonic, and the following harmonics are known as higher harmonics. With regard to a 60-Hz electrical system, […]

Temperature is a parameter that often needs measuring. It may be within an enclosure, on a PCB, remotely or even “wirelessly”. Wireless, in this case, does not necessarily mean a remote sensor communicating using radio frequencies, it can mean a pyroelectric sensor. Pyroelectric sensors are very long wavelength detectors which measure radiation in the 6-15μm […]
The multimeter had its roots in a surprising observation by Hans Christian Ørsted during a lecture in 1820. He saw that a compass needle deflected from its alignment with the earth’s magnetic north pole when a metal conductor carrying electric current was moved close by. This action suggested that an analog meter could be built […]

Two high-end test instruments are connected to display waveforms and Lissajous patterns. Hi and welcome to our 56th Test and Measurement video. Today we’ll do one of my favorite things in the world of electronics, and that is to connect two products by different manufacturers and see them work in concert. Both very high quality […]
A lab that aspires to do advanced electronic research or product development must have one or more oscilloscopes and spectrum analyzers. Despite their obvious similarities, the two are totally different instruments. The oscilloscope functions in both time and frequency domains, the latter by means of its math/FFT (Fast Fourier transform) capability. The spectrum analyzer, in […]
