San Francisco — At last year’s OFC 2024, the next speed of optical connections (1.6T) was all talk with one exception. In a back room, Keysight demonstrated a 1.6T optical link between an arbitrary waveform generator and a bit-error-rate tester. The demonstration was a transmission of raw, unstructured bits. One thing was clear, AI was…

OFC 2025: Test equipment
This year’s OFC in San Francisco featured one thing, or so it seemed: 1.6T. Every company making optical modules was showing them lest they be left behind in the always accelerating data rate race. As with any emerging technology, test equipment must lead the way. After all, how do you know if anything works unless […]
OFC 2025: Interoperability demos
The Ethernet Alliance and Optical Internetworking Forum featured interoperability demonstrations at data rates up to 800 Gbps. San Francisco — With so many companies and products comprising the optical networking ecosystem, interoperability is paramount. All those semiconductors, optical modules, switches, routers, servers, test equipment, and the software that makes them function must first provide their…
APEC 2025 test equipment: oscilloscopes and probes
Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and […]
Free and low-cost online EE tools aid in design
Downloadable and online free and low-cost EE tools help engineers design and analyze circuits. The internet is full of EE tools from equipment manufacturers, semiconductor manufacturers, independent EEs and hobbyists. Some are web-based that you can use with just a browser. Some you need to download and install on your PC while others you install […]
How to determine noise figure: part 4
Two incompatible definitions of noise factor can lead to confusion, which you can alleviate by understanding where the differences lie.
IEEE Phased Array 2024: what we saw
The IEEE Phased Array conference occurred in Boston on October 15-17, 2024. This specialized conference had a small exhibit floor. Here is some of what was on display. Boston — The 2024 IEEE International Symposium on Phased Array Systems & Technology moved into the city after taking place in a suburban Boston hotel for several…
14-bit oscilloscope delivers low noise, fast updates
Keysight’s InfiniiVision HD3 series oscilloscopes let you see signals with 4x the resolution of 12-bit instruments.
Video: How should 5G, 6G evolve?
EE World spoke with Matsing’s Manish Matta and Keysight’s Roger Nichols on how 5G is evolving into business use cases and where 6G could play a role.
Solar-array simulator gets boost to 8.4 kW
Keysight Technologies, Inc. expands the MP4300A Series Modular Solar Array Simulator (SAS) with two new mainframe and module models, delivering total power up to 8.4-kW in a 2U footprint. The SAS solution is a six-channel modular platform that emulates the behavior of photovoltaic (PV) segments and simulates all conditions a craft or satellite will encounter in space with high fidelity.
