SAFETY GUIDELINES FOR HIPOT TESTING
AND SETTING UP A SAFE TESTING AREA
A few simple steps ensure testing takes place safely
when potentially lethal voltages and currents are
involved in the testing process.TEST INSTRUMENTS TACKLE 5G
The high frequencies involved in 5G will force a re-think
of how to go about characterizing circuits and systems.WHAT YOU SHOULD KNOW ABOUT
WI-FI IN THE 6GHz BAND
While there are still interference issues to be resolved,
new specifications for Wi-Fi in the 6-GHz band will
bring instantly better wireless performance.HOW STANDARD AND CONFORMANCE TESTS
SHAPE THE FUTURE OF 5G NEW RADIO
Specs for 5G NR release-15 have been finalized and
plans call for product introductions this year.TEST INSTRUMENTS AND PCB REPAIR
Basic tools such as DMMs and oscilloscopes may be
the only test gear needed for small printed circuit
board repairs, but it pays to know when automated
systems would be a better choice.WHAT'S NEW IN USB POWER DELIVERY 3.
A new version of the USB spec puts additional demands on
testing regimes that wring out power-handling options.UNDERSTANDING TOTAL HARMONIC
DISTORTION MEASUREMENTS
Most electronics engineers and technicians have a
good understanding of total harmonic distortion (THD).
But there are a few elusive details that come into play
during THD measurements.TESTING LVDS DEVICES AT THE
MARGINS WITH AN AWG
Advanced arbitrary waveform generators have
simplified the testing associated with communications
over low-voltage differential signaling lines.REMOTE COMMUNICATION WITH USBTMC
Simple connections employing USB can replace more
expensive GPIB setups in test instrumentation.HOW TO MEASURE CURRENT AND
ENERGY USE ACCURATELY
General-purpose test equipment can have trouble
measuring small currents, particularly if they only
happen briefly. New specialized instruments go a
long way toward solving this problem.WILL 5G BE LETHAL?1
