Santa Rosa, Calif.—Keysight Technologies today announced chipset technology that will bring real-time oscilloscope bandwidth to higher than 100 GHz. Calling it a "technological breakthrough" but not giving any specifics, Keysight is clearly looking to take the lead in the never-ending bandwidth race.
Such high bandwidths are needed to keep up with serial data streams as the industry moves to 56 Gbps per lane with some engineers looking to 112 Gbps. At 56 Gbps running NRZ (non-return-to-zero) modulation, such bandwidth is needed because 56 G NRZ has clock rates of over 28 GHz (more like 32 GHz given overhead). Thus, 100 GHz barely captures the third harmonic.
Keysight's current bandwidth leader, the 63 GHz DSAZ634A Infiniium oscilloscope, will next year be eclipsed by one with higher bandwidth.
Keysight's current bandwidth leader, the DSAZ634A Infiniium Oscilloscope, is currently in third place in the bandwidth race behind rivals Teledyne LeCroy at 100 GHz and Tektronix at 70 GHz.
Keysight is banking on its Indium Phosphide process to bring about the bandwidth leap that could put the company in to bandwidth lead. Although no products are expected on the market until 2017, we can always hope for a demonstration at DesignCon 2017. Given this announcement, I'm already looking forward to next year's conference.
The announcement coincides with the start of Keysight's Scope Month
