Most engineers are familiar with charge-coupled devices (CCDs) employed as image sensors. Pixels in a CCD sensor consist of P-doped metal-oxide semiconductor capacitors arranged in columns and rows to form an array. Light striking each pixel is converted to an electrical charge that varies according to the light intensity at that pixel. The CCD transfers […]

The new Keysight P9002A parallel parametric test system provides high throughput and cost effective wafer test to accelerate time-to-market in R&D and lower cost-of-test in manufacturing. The global semiconductor shortage has created a growing demand for semiconductors in the automotive industry, as well as digital devices and home appliances. Ongoing technology innovation in semiconductors is […]
Audio measurement software supports GRAS SysCheck2-capable mics
The latest update to APx500 audio measurement software, version 7.0, adds new enhancements suited to a wide range of audio test applications, whether analog, digital, or acoustic. Developed by GRAS Sound & Vibration, also part of Axiometrix Solutions, SysCheck2 is a system designed to actively verify whether the sensitivity of a microphone has drifted since […]
Compact automotive data logger records multiple data streams simultaneously
The x2e XORAYA ML-N4000 is a powerful compact datalogger intended for automotive applications which is able to record data from multiple bus systems simultaneously at data rates of up to 4 Gbit/sec. Each logger comes with six slots for various automotive interface needs. The data logger has 6x slots for individual interface configuration of the […]
How to measure display screen output
The flat display screens of today typically look great. But when it comes to quantifying their output, confusion may reign. There are three main measurement tools used to gage the output of displays. Before we get into their details, it might be helpful to review the main display technologies we are typically trying to measure. […]
PHY interposer supports PCI Express 5.0 CEM spec
The CrossSync PHY technology now supports the PCI Express 5.0 Card Electromechanical (CEM) specification. This new CEM interposer (PE230UIA-X) joins the existing CrossSync PHY enabled M.2 form factor interposers (PE210UIA for PCIe 4.0 and the PE222UIA for PCIe 5.0), with more form factors in development to fill out the portfolio of cross-layer probing. Engineers at […]
Making pictures from sound on an oscilloscope
If you take an ordinary sound file and feed it to both channels of an oscilloscope operating in X-Y mode, you’ll get an image on the scope looking a lot like a pulsating straight line at some angle to the horizontal. But the situation changes if you use a stereo signal with the left channel […]
Signal generators feature high signal purity and frequency stability
The Rubidium signal generator family delivers outstanding signal purity and frequency stability, even at high output power levels, across a broad frequency range of 9 kHz to 43.5 GHz. Coupled with built-in, easy-to-use, at-location frequency and power calibration capability, Rubidium offers exceptional overall utility and long-term value in a broad range of commercial and military/aerospace […]
Portable spectrum analyzers reach 26.5 GHz
New base models for the portable R&S FPL1000 take spectrum and signal analysis capabilities up to 26.5 GHz. They combine the functionality of benchtop instruments and the portability of a handheld instrument, with intuitive features to make high performance measuring on the go fast and simple. For the series, two new models have been added […]
Economical scopes now include zone triggers, Bode plots and power analysis
The 2560B Digital Storage (DSO) and Mixed Signal Oscilloscope (MSO) Series offers 100 MHz, 200 MHz and 350 MHz bandwidth models in a four-channel configuration, with a sample rate of 2 GSa/sec and a maximum memory depth of 200 Mpts.
