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 […]
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 […]
The proving ring – An alternative to dead-weight calibration, Part 2
The proving ring implements a simple principle of physics to provide precise and tangible indication of applied weight ranging up to hundreds of thousands of pounds Part 1 of this article looked at the basic problem of calibrating sensor-based data acquisition and especially the problem of calibration of weight and force. This part looks at […]
Five-year tests help reveal why PV modules poop out
Some PV solar panels degrade long before others, a fact that makes it tough to estimate the economics of a given solar panel installation. But researchers in Germany are shedding light on solar panel degradation through life tests being run on panels using different PV technologies. Tests took place on PV panels sitting on the […]
Branch feeder monitors get digital fault monitoring upgrade
A Digital Fault Recording (DFR) feature is now among the capabilities of the Model BFM-II Second-Generation Branch Feeder Monitor. Designed specifically for electrical distribution substation applications, the DFR functionality provides substation engineers with critical information regarding relay tripping and reclosure operations, power disturbances and other system anomalies. The BFM-ll’s unique design allows it to easily […]
How to measure CCD and CMOS image sensor qualities
Today, about 95% of all digital cameras use CMOS image sensors with the rest employing CCDs. From the standpoint of sensor outputs, the main difference between CMOS and CCD sensors is that each pixel in a CMOS sensor has its own readout circuit next to the photosensitive area. In CCDs, charge collected in individual pixels […]
Setting input parameters in the Tektronix MDO3000 oscilloscope
Input parameters in the Tektronix MDO3000 Series Oscilloscope are determined by the user. This is done by pressing one or more of the channel menu buttons, causing the horizontal channel menu to appear. Menu items are: • Scale – Fine, Offset, Position, Probe setup and Deskew • Coupling – ac or dc • Termination – […]
Sampling oscilloscopes get built-in 53-Gbaud clock recovery units
A Clock Recovery Unit (CRU) option is now available for the BERTWave MP2110A scope that supports trigger clock generation from a 53-Gbaud PAM4 optical signal. When combined with existing oscilloscope functionality, the new 53-Gbaud CRU allows the MP2110A to serve as an all-in-one solution that can more cost-effectively and efficiently evaluate various PAM4 optical modules […]
Basics of flat screens in test equipment
Flat-screen technology has become ubiquitous. It has almost completely replaced CRTs in test instruments as well as in other appliances. Unfortunately, flat-screen tech can be a bit confusing because of vendors that use their own trade names to refer to their specific type of flat display technology. Here, we’ll try to clear up some of […]
