Modern power supplies are generally divided into two types, linear supplies and switching supplies. Linear supplies may contain a transformer that outputs the required voltage(s) and a rectifier such as a full-wave diode network to produce the desired dc. Additional circuitry provides whatever filtering and/or regulation that is appropriate. A simple, minimal power supply is […]

DC electronic load handles 7.2 kW, sits in 3U space
Intepro Systems, a market leader in power component and power system automated test equipment (ATE), introduces the EL 9000 B Series of electronic DC loads. The EL 9000 B Series is offered in 15 models with rated peak power from 1,200 to 7,200 Watts. The new “B” Series units are a major upgrade to the […]
Space Vectors aide drive for optimal efficiency
by Johannes Teigelkötter, HBM Using space vectors in test equipment helps engineers get a clearer, more precise picture of three-phase motor electromagnetics. With the continuing emphasis on the use of renewable sources of energy, as opposed to the reliance on fossil fuels, advances in induction motor design are allowing for greater efficiencies in both consumer […]
Software for real-time scopes handles automated PAM-4 pre-compliance testing, report generation
Keysight Technologies, Inc. (NYSE: KEYS) today introduced measurement application software designed to help engineers quickly and accurately measure and quantify PAM-4 (pulse amplitude modulation with four amplitude levels) signals. The software is used with the Keysight S-Series, 90000A, V-Series, 90000 X- and Z-Series real-time oscilloscope platforms and the 86100D DCA-X Infiniium sampling oscilloscope. The new […]
Basics of Electronics Testing for Automotive Interiors
Vehicular electronics and interiors have their own testing standards that can differ dramatically from those of other industries. James Bryans, Manager, Environmental and Performance Intertek Group plc One might assume that many of the tests run at third-party testing facilities would already have been completed by product developers. Surprisingly, that is frequently not the case. Often there […]
Air Temperature and Velocity Scanner Thermally Characterizes Electronic Enclosures
Advanced Thermal Solutions, Inc. (ATS) now offers the ATVS-2020 scanner which measures airflow temperature and velocity of inside electronic devices. The ATVS-2020 scanner accommodates up to 32 sensors for precise, multi-point field mapping of test domains, including housings and PCB surfaces. The result is a highly accurate thermal characterization. Each dual-purpose sensor simultaneously measures both […]
USB-connected vector signal generators produce 2 GHz, 4 GHz analog outputs
Saelig Company, Inc. has announced the availability of Triarchy Techologies’ VSG2G1 and VSG6G1 RF Vector Signal Generators – very cost effective USB-connected portable, pocketable RF signal sources with capabilities that provide features and functions comparable to full-size analog RF signal generators. Offering frequency ranges up to 2.2GHz (VSG2G1) or 6.2GHz (VSG6G1), frequency sweep, frequency hopping […]
VNAs get E-band measurement options
Anritsu Company introduces an E-band option for its ShockLine™ MS46500B series of 2- and 4-port performance Vector Network Analyzers (VNAs) that addresses the market need to lower cost-of-test for E-band components. With the option installed, the MS46500B series can reduce production costs and more efficiently verify the performance of high-frequency passive components, such as antennas, […]
Fluke 1736 Three-Phase Power Loggers now available from Newark element14
Newark element14 has added the Fluke 1736 Three-Phase Power Logger, which automatically captures and logs voltage, current, power, harmonics and nearly 500 other power quality parameters across three phases, to its product portfolio. It optimizes system operations and minimizes uncertainty to allow engineers to make better and more thorough power quality and energy consumption decisions. […]
VIDEO: Fluke ScopeMeter Frequency Spectrum
A Fluke 190-502 is connected to the AFG output of a Tektronix MDO 3104 oscilloscope and the frequency spectrum of a number of signals is observed.
