Testing Wi-Fi 6E performance
The 6 GHz band brings 1,200 MHz of additional spectrum to Wi-Fi which complicates the task of testing a verifying features. Eve Danel, LitePoint Now that the 6 GHz region of the spectrum is available for unlicensed use, Wi-Fi 6E devices are on their way to store shelves. Manufacturers face the juggling act of comprehensively […]

IEEE 802.3 Ethernet next-gen study group holds successful webinar
IEEE 802.3’s progressing “Moving Beyond 400Gb/s Ethernet Study” group members held a highly interactive and successful video webinar in conjunction with Lightwave with an excellent question and answer sections. This was a 100+ page three-hour rich experience meet up with key observations, data, and current conclusions from various industry leaders. After the recent EA’s TEF, […]
The difference between TDR instruments and scope-based TDR measurements
Often a transmission line is buried, concealed behind finish surfaces, or otherwise not readily accessible. So it is difficult to locate faults by means of visual inspection. It is, however, feasible to locate such discontinuities via a test instrument known as the time domain reflectometer (TDR). The TDR is sometimes compared to a radar installation, […]
A comparison of EMI test setups and specifications for automotive, industrial and defense applications, part 1: conducted emissions
by Timothy Hegarty, Applications Engineer, Texas Instruments This article compares electromagnetic interference (EMI) requirements in automotive, industrial, and defense product family standards, specifically various test parameters, test equipment, test setups, and test methods [1-4] for conducted emissions (CEs). The comparison includes widely used dedicated standards in each industry: Comité International Spécial des Perturbations Radioélectriques (CISPR) […]
Signal meets power meets data in miniature connectors
Contributed by Niklas Wittler, Global Product Manager Board to Board Solutions Connector specialist Harting not only wants to cater to the megatrend of miniaturization, but also lead it with clever solutions. This most of all concerns miniaturized and flexible PCB connections. Especially as there is no place where miniaturization takes greater effect than inside the […]
Unlicensed spectrum use: What’s the technology behind it?
Unlicensed LTE lets wireless carriers offload traffic to Wi-Fi frequencies, but it must coexist with Wi-Fi and not interfere. Here’s how it works.
