Agilent Technologies Announces Breakthrough Chipset for Next-Generation, High-Bandwidth, Real-Time Oscilloscopes

Agilent Technologies Announces Breakthrough Chipset for Next-Generation, High-Bandwidth, Real-Time Oscilloscopes


Agilent Technologies Inc. announced breakthrough functionality in next-generation, high-bandwidth oscilloscopes with the successful turn-on of a front-end chipset that uses indium phosphide (InP) technology. The new chipset will enable the company to deliver oscilloscopes in the first half of 2010 that offer true analog bandwidths greater than 16 GHz. 

In the next few years, as data rates extend beyond 8.5 Gb/s, engineers will need oscilloscopes with true analog bandwidths greater than 16 GHz. In addition, the upcoming IEEE 803.2ba 40/100G standard will drive the need for high-quality, real-time signal analysis capabilities to 16 GHz and beyond.

InP technology offers the same capability without sacrificing the reliability and manufacturability associated with Agilent instrumentation.

The InP process technology also has superior material properties compared with Agilent's prior-generation gallium arsenide (GaAs) process. InP technology provides higher saturated and peak electron velocities, higher thermal conductivity, lower surface recombination velocity, and higher breakdown electric field. These benefits mean true analog bandwidths can be pushed to new limits.

In addition, InP technology provides the following measurement benefits compared with other technologies available today:

  • significantly flatter response at high frequencies;
  • higher measurement accuracy because of the low-noise, nonconductive substrate ; and
  • higher reliability due to lower power consumption.

Agilent implemented an in-house fabrication facility to gain ultimate control of precision in the InP process. "Our expertise in microwave semiconductor technology has proven key in tuning this breakthrough Indium phosphide process to deliver leading specifications for real-time oscilloscopes," said Bob Witte, vice-president of Agilent's Technology Leadership Organization.

Customers already are seeing the benefit of Agilent's InP process in the J-BERT N4903B high-performance serial BERT, which offers complete jitter tolerance testing, and in the N4916B de-emphasis signal converter. InP technology has delivered pulse fidelity to rise times faster than 20 ps and offers headroom for tomorrow's needs.

"Our first oscilloscope family offering this new high-speed chipset will start at 16 GHz bandwidth," said Jay Alexander, vice president and general manager of Agilent's oscilloscope organization. "We expect to introduce this high-bandwidth family in the first half of 2010. These new products will complement our existing lineup of oscilloscopes and ensure that we can meet upcoming customer needs in a timely manner."

Agilent currently offers high-performance Infiniium 90000 Series oscilloscopes with bandwidths up to 13 GHz. More information on Agilent oscilloscopes is available at
