PCIM Europe is often proclaimed to be the world’s leading exhibition and conference for power electronics, intelligent motion, renewable energy, and energy management. Recently finishing up in Nuremberg, the exhibition floor of PCIM featured over 500 booths. Here are some of the more notable test & measurement we saw in touring the event. NEXT PAGE: […]
Measuring Ethernet and WiFi transmissions
The Ethernet computer networking protocol is used in local area networks, metropolitan area networks and wide area networks. While the term is often used to distinguish wired data transmissions from Wi-Fi, both use parallel protocol details, notably 48-bit MAC address and Ethernet frame format. Actually, Wi-Fi is Ethernet over a different medium. There are a […]
Exploring the Siglent SHS 1102 hand-held oscilloscope through use of reference and recorder functions
The word oscilloscope is mostly used to refer to a bench-type instrument, but scopes also exist as hand-held, battery-powered versions. The bench-type oscilloscope, model-for-model, usually has more features, higher specifications such as bandwidth and sampling rate, more controls, deeper menus and so on. The hand-held, battery-powered oscilloscope, in contrast, is smaller and more portable, well-sealed […]
When scopes measure voltages not referenced to ground
Consider a typical bench-type oscilloscope that connects to the ac outlet. It typically has an equipment grounding conductor that connects to the building’s electrical grounding system. Consequently, it is hazardous to connect the scope probe’s ground return lead to a printed circuit board or electrical equipment terminal or wire that is referenced to and floats […]
Oscilloscope designs change with the times
by Miles Budimir, Senior Editor From portable scopes to a wide array of testing tools, oscilloscope design keeps up with the times. A key piece of electronic test equipment for well over half a century, oscilloscopes have long given engineers and designers insight into the invisible world of electrical signals. And as those signals got […]
Handheld scope automatically sets up triggering and display features
Today’s industrial machinery is more reliable and efficient, but can also be more difficult to troubleshoot because of the complexities of its advanced systems. The new Fluke ScopeMeter 120B Series Industrial Handheld Oscilloscope is designed to address these challenges with innovative features that improve the speed, efficiency, and accuracy of troubleshooting complex electro-mechanical systems. The […]
H-P, Agilent, Keysight: New name, same reputation
Those of us who have been around electronic instrumentation for a while can remember the days when Hewlett-Packard instruments were considered the cream of the crop. Where I worked, we always tried to get to the lab early on the days we had tests to run so we could get our hands on the highly […]
