In measuring or displaying weak signals, noise places the ultimate limit on detectability. It usually appears as a fluctuating horizontal line known as the noise floor in a spectrum analyzer of oscilloscope in FFT or RF mode. In the time domain, it appears as a thickening of the trace and in severe instances, causes a […]
Open-source tool addresses signal integrity problems
An open-source software tool called SignalIntegrity handles signal integrity problems for design and test engineers. More than 1,500 users have downloaded the free Python-based software since it has been made available. The new SignalIntegrity software is now available from Teledyne LeCroy and provides extra analysis capabilities to Teledyne LeCroy’s WavePulser 40iX High-Speed Interconnect Analyzer, a […]
Ten-watt 1×1-in dc/dc converters target rugged industrial/rail apps
The new THN 10 WIR series 10-W high-density dc/dc/ converts come in the industry standard 1×;1-in footprint and are qualified for rugged industrial and railway applications, and are certified to EN 50155 and EN 61373 standards. The THN 10 WIR series of ruggedized 10-W dc/dc converters are designed and manufactured for high-reliability in harsh environments. […]
Wide input range, dimmable 1-A drivers handle up to 15 high-brightness LEDs
The RCDE-48 series of LED driver modules accept up to 60 Vdc input voltage and produce a 1,050-mA constant-current output with analog or PWM deep dimming. Developed by RECOM, the RCDE-48 series of LED driver modules can provide up to 350 mA, 700 mA or 1,050 mA of constant-current to drive strings of up to […]
LPDDR5 socket boasts same footprint as the IC it holds
New Grypper/G40 test sockets, part number 109111-0003, for the latest LPDDR5 memory devices allow testing of the newest generation of Package-On-Package type LPDDR5 devices that have 496 Ball 0.4-mm pitch, with speeds up to 5500 Mb/sec. The LPDDR5 Grypper/G40 socket fits to the same location/PCB footprint as the device allowing development and failure analysis. This […]
Researchers eyeball potassium batteries as sustainable replacements for lithium cells
A team of scientists at Tokyo University of Science are focusing on the replacement of the exhaustible element lithium with better alternatives like sodium and potassium. Sodium and potassium are in the same alkali metal group in the periodic table of elements, and their chemical natures are, therefore, quite similar. But, unlike lithium, these elements […]
Two/four-channel 100-350 MHz scopes feature 200-Mpt memory, 10-in touch-screen, external mouse/keyboard control, 50-MHz waveform generator
The new Siglent SDS2000X Plus Digital Oscilloscope Series consists of four models: one two-channel 100-MHz bandwidth (software upgradeable to 350 MHz) and three four-channel models (100/200/350 MHz.) The 350-MHz models can be upgraded to 500 MHz on two independent channels. A large 10.1-in capacitive touch-screen supports multi-touch gestures. The oscilloscope range also offers a 10-bit […]
Get ready for SiC-GaN combo power transistors
Researchers in Sweden have come up with a way of putting gallium-nitride transistor structures on a silicon-carbide substrate that potentially lowers the ON resistance of power FETs by an order of magnitude below that of commercial devices available now. The scientists hail from Sweden’s Linköping University and SweGaN, a spin-off company from materials science research […]
Programmable dc loads feature high-speed pulse and transient loading
The DL Series of Digital, Programmable dc Loads, are designed to support the testing requirements for the latest generation of off-line power supplies, dc-dc converters and LED drivers. The DL Series is also equipped to handle a wide range of battery testing requirements. The devices are offered in three power ratings (125 W, 250 W […]
Ethernet switch passes 1000BASE-T1 compliance tests for automotive apps
Rohde & Schwarz and Marvell were the first companies to successfully execute 1000BASE-T1 compliance tests, for the Marvell’s 88Q2112 Ethernet transceiver, using an R&S RTO oscilloscope. The latest improvements to the R&S RTP oscilloscope family include the 16-GHz acquisition bandwidth required to perform signal integrity tests and debugging for SerDes, LVDS, PCIe Gen 3.0, MIPI […]
