New chipsets are enabling the next oscilloscope generation
23 March 2016

Keysight Technologies has claimed a technological breakthrough for building the world’s highest-bandwidth oscilloscopes with the successful turn-on of chipsets that take advantage of the company’s leading edge Indium Phosphide (InP) semiconductor technology. As from 2017, Keysight is scheduled to begin introducing real-time and equivalent-time oscilloscopes that take advantage of these new chipsets to offer bandwidths greater than 100 GHz with significantly better noise floors than what is currently on the market.
The announcement came at the start of Keysight’s ‘Scope Month’ in March, an entire month focused on celebrating breakthrough technology and the engineers who enable it. Highlights also included new oscilloscope measurement tips and content, access to measurement experts and daily oscilloscope giveaways.
Over and above sheer bandwidth, the forthcoming real-time oscilloscopes will feature key innovations such as 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 synchronisation.
Engineers working with next-generation, high-speed interfaces, such as the upcoming IEEE P802.3bs 400G, as well as terabit coherent optical modulation, will need oscilloscopes for electrical parametric measurements. These technologies and others will play a key role in validating fifth-generation wireless (5G) designs. As data rates continue to extend beyond 56 Gbps NRZ and 56 GBaud multi-level signalling, 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.
