Megohmmeter measurements can now be more accurate, rapid and safer than ever before. JEFF JOWETT, MEGGER A considerable number of electronics personnel working throughout the electrical industry are military trained. And many of them learned on a simple hand-cranked analog meter, properly termed a megohmmeter, or insulation tester. These testers were typically 500-V units that […]
You passed: Getting products through EMC/EMI compliance tests
Pre-compliance tests run in your own lab can avoid bad news when products go into formal conformity checks. DYLAN STINSON, TEKTRONIX INC. EMI regulations are in place to ensure reliability and safety for users of electrical and electronic equipment. With few exceptions, any product emitting or susceptible to electromagnetic interference must be certified for EMI […]
RFIC test capability for NB-IoT and eMTC standards
New NI-RFmx NB-IoT/eMTC measurement software complements National Instruments’ existing RF test capabilities for wireless technologies ranging from 802.11a/b/g/n/ac/ax to Bluetooth to 2G/3G/4G/5G standards. NB-IoT and eMTC drive a wide range of machine-type communication applications by delivering on key performance criteria such as extended range and lower power consumption. Compared to existing LTE technology, the NB-IoT […]
Tips on buying a new oscilloscope
Answers to a few basic questions can help clarify what kind of scope makes sense for your workbench. JAMES MCGREGOR, NEWARK ELEMENT14 For many engineers, the oscilloscope is the most useful and versatile tool on the bench. So when it’s time to buy a new one, it’s important to make sure the scope meets your […]
Why 5G is going to over-the-air testing
Cables and connectors may become artifacts of the past for communication electronics as the world moves to 5G standards. SHERI DETOMASI, KEYSIGHT TECHNOLOGIES, INC. 5G is rapidly approaching and there is a lot of talk about over-the-air (OTA) testing – that is, testing without the DUT physically connected to the test equipment. I’ve seen test […]

Featuring extremely fast switching speed, superior signal integrity, and low distortion, the Lucid range […]
Infrared cameras for PCB development and diagnosis
IR cameras can help size up the surface temperatures of electronic components, PCBs, and other objects to reveal unseen problems. ALAN J. LOWNE, SAELIG CO. INC. Thermal imagers, also called infrared cameras, capture a 2-D representation of objects in front of their germanium optics (ordinary optical glass impedes IR wavelengths). They present a visible version […]
Functions and features of advanced hipot testers
Modern instruments help to check whether manufactured equipment meets the proliferating variety of international safety standards that govern factors such as grounding and the ability to withstand overvoltages. KEVIN CLARK, VITREK, INC. Electrical safety testers – often referred to as hipot testers – are an integral part of electrical and electronic equipment manufacturing. Hipot testers get […]
Will high test instrument costs keep the next Steve Wozniak out of the tech business?
LEE TESCHLER EXECUTIVE EDITOR Back in the heyday of personal computing, it was possible to do state-of-the-art work without making a big investment in test equipment. To see what I mean, consider the development of the first 5.25-in. floppy disk drive for the Apple II PC. Introduced at the Consumer Electronics Show in early 1978, […]
