Keysight Technologies, Inc. announced a technological breakthrough for building the world’s highest-bandwidth oscilloscopes with the successful turn-on of chipsets that take advantage of Keysight’s leading edge Indium Phosphide (InP) semiconductor technology.
The new chipsets will enable Keysight to deliver real-time and equivalent-time oscilloscopes in 2017 that offer bandwidths greater than 100 GHz with significantly better noise floors than what is currently on the market.
The new technology will also include a new 10-bit analog-to-digital converter (ADC) that allows higher vertical resolution of signals captured at ultra-high bandwidth, and more than one maximum bandwidth input channel per oscilloscope to enable tight channel synchronization.
“Keysight continues to innovate in the Indium Phosphide process to deliver leading performance to meet our customers’ measurement needs,” said Jay Alexander, senior vice president and chief technology officer of Keysight Technologies. “Our expertise in microwave semiconductor technology has allowed us to deliver the next-generation Indium Phosphide process to create a breakthrough in real-time and equivalent-time oscilloscope performance, and it will enable significant advancements in other Keysight products over time as well.”
This new technology will help engineers working with next-generation, high-speed interfaces, such as the upcoming IEEE P802.3bs 400G, as well as terabit coherent optical modulation. These technologies and others will play a key role in validating fifth-generation wireless (5G) designs. And these interfaces will drive the need for high-performance, real-time and equivalent-time signal analysis capabilities to 100 GHz and beyond. As data rates continue to extend beyond 56 Gb/s NRZ and 56 GBaud multi-level signaling, engineers will need not only higher bandwidth, but also higher vertical resolution and lower noise floors to address their validation challenges, and the new chipsets have been designed with this in mind.
