The company says the oscilloscopes will also feature 10-bit A/D converters and more than one maximum bandwidth input channel per oscilloscope.
Likely applications for these high bandwidth oscilloscopes include 5G mobile systems with the upcoming IEEE P802.3bs 400G, as well as terabit coherent optical modulation, which will need oscilloscopes for electrical parametric measurements.
Keysight claims it is the only company that produces oscilloscopes made with InP chipsets. Investing in the InP process is said to have allowed the company to scale the transistor switching frequencies beyond the 300GHz level, enabling higher bandwidths in both the chips and the end products.
“Our goal is to move multiple performance parameters ahead simultaneously,” said Dave Cipriani, vice president and general manager of Keysight’s oscilloscope business “The next-generation oscilloscopes deliver bandwidths starting at 80GHz and going beyond 100GHz. They will have a lower noise density, providing higher-resolution measurements in tightly-synchronised, multi-channel systems. Whether customers are measuring higher baud rates, higher order QAM signals or multi-channel systems, these next-generation scopes will meet their needs.”
This announcement coincides with the start of Keysight’s Scope Month, during which it will offer oscilloscope measurement tips and content, access to measurement experts and daily oscilloscope giveaways.
