Prepare yourself for the updated standards about to take hold in power equipment that includes external adapters. Ron Stull • CUI Inc. A power adapter is a barrier between lethal ac mains voltage and the dc power line for end equipment. Different environments, however, demand different adapter construction to meet safety levels. For example, domestic, […]
Why electrolytic capacitors blow up
Electrolytic capacitors have a reputation for failing spectacularly when mistreated. Leland Teschler • Executive Editor Pop open a common LED bulb and you’ll often find an electrolytic capacitor occupying a place in the input from the ac line. Though illumination-grade LEDs generally have lifetimes exceeding 10,000 hours, the electrolytic caps in their base may not […]
Why your local landfill won’t contain lithium batteries
Leland Teschler • Executive editor Consumers with an inclination toward sustainability have been bummed out over recent revelations that most of the plastics they have carefully separated, washed, and placed in recycling bins typically end up in the local dump. So it may come as good news that dead lithium batteries are increasingly likely to […]
Advanced 500-MHz scopes provide 1mV/div min input range, digital trigger system
The Teledyne Test Tools T3DSO2000A Oscilloscopes are available in two-channel and four-channel versions with analog bandwidths from 100bMHz to 500 MHz. Each model offers a maximum sample rate of 2 GSa/sec and a maximum memory depth of 200 Mpts in half-channel mode. The T3DSO2000A series employs a new generation of high-speed display technology that provides […]
VNA test cables sport flex life exceeding 100,000 cycles
A new series of highly flexible VNA test cables are designed to address a range of demanding test and lab applications. Fairview Microwave’s new high-frequency VNA test cables display excellent electrical properties such as exceptional phase stability of ±6° at 50 GHz and ±8° at 70 GHz, as well as VSWR of 1.3:1 at 50 […]
First 256-GSa/sec arbitrary waveform generator with 65-GHz analog bandwidth
The M8199A is the first 256 GSa/sec arbitrary waveform generator (AWG) with 65-GHz analog bandwidth. It sits in a compact two-slot AXIe module. Making this development possible is a new digital-to-analog converter application-specific integrated circuit (DAC-ASIC) that translates memory data into an analog signal. In addition, Keysight created a new package that avoids soldering sensitive […]
Protocol analysis system for PCIe 5.0 hosts 16 lanes
The first 16-lane protocol analysis system for PCI Express 5.0 operates at 32 Gbps per lane. The VIAVI Xgig 5P16 Protocol Analyzer delivers detailed traffic analysis and jamming capabilities, enabling test and validation to meet the most demanding performance needs of emerging compute-intensive applications such as 400 Gigabit Ethernet, artificial intelligence (AI), IoT and hyperscale […]
Instrumentation handles active electronically scanned array radar testing
New test and measurement setups handle transmit-receive-module (TRM) performance validation in modern active electronically scanned array (AESA) radars found in the global aerospace and defense industry. Typical TRM test cases can be covered with a single Rohde & Schwarz network analyzer as a turnkey solution, such as the R&S ZNA. If higher performance–such as the […]
4:1-input, 15-to-30-W dc-dc converters sport medical/ICT safety certifications, 5-kVac isolation
The 15-to-20-W PXG-M and 30-W PXD-M30 board-mount dc-dc converter series carries a 4:1 input ranges of 9-to-36-Vdc and 18-to-75 Vdc. The two series are certified to IEC 60601-1 (medical) and IEC 62368-1 (ICT – Information and Communication Technology equipment). The input-to-output isolation is 5,000 Vac allowing their use in multiple medical and industrial applications. The […]
Study shows slightly safer UV-C wavelength kills Covid-19 bug
Hiroshima University researchers say Ultraviolet-C light with a wavelength of 222 nm effectively kills SARS-CoV-2. Other studies involving 222-nm UV-C have so far only examined how well it kills seasonal coronaviruses structurally similar to the SARS-CoV-2 but not on the COVID-19-causing virus itself. Operation at 222 nm is said to be safer than emitting light […]
