Leland Teschler • Executive editor The National Academy of Sciences recently released its conclusions about what sickened dozens of American Embassy diplomats in Cuba, a phenomenon dubbed the Havana Syndrome. Though the panel reached no definitive conclusion, it found pulsed RF (a.k.a. directed microwave energy) was the most likely cause. Panel members could not rule […]
Looking for ghostly goings-on with a milligauss meter
Tune in to TV shows that are purportedly about ghost hunting and you’ll often see people wandering around in the dark with an instrument called a milligauss meter. A milligauss meter detects changing magnetic fields. (It won’t detect static fields as from a bar magnet.) When a milligauss meter shows a reading during a ghosting […]
BGA266 sockets provide 30-GHz bandwidth without significant performance loss
A new high-performance BGA socket handles 0.65-mm pitch BGA 266-pin ICs. The SG-BGA-7335 socket is designed for 12×12-mm BGA packages and operates at bandwidths up to 30 GHz with less than 1 dB of insertion loss. The sockets is designed to dissipate up to 4 W with help from a heat-sinking compression screw. The contact […]
USB scope features low noise, four channels, 1 GSa/sec signal acquisition
The Handyscope HS6 is a USB 3.0 oscilloscope is available in models with 200 MSa/sec up to 1 GSa/sec sampling rate. The Handyscope HS6 has a flexible resolution that can be set from 8 bit to 16 bit, allowing high-resolution measurements. With its high accuracy (0.25 %) and low noise (240 μVRMS), measured signals are […]
Lissajous patterns: using a scope for display signals
The most common use of an oscilloscope is to display one or more signals in the time domain. A variation is the display of signals in the frequency domain. In most oscilloscopes that have this capability, the frequency domain is accessed by pressing a button labeled Math. Then, press the soft key, a control that […]
