Real-time oscilloscope breaks double-digit bandwidth barrier
Oct 1, 2004 12:00 PM 

With a maximum real-time bandwidth of 13 GHz and a maximum sample rate of 40 Gsample/s, Agilent Technologies Inc.'s latest introduction surpasses the double-digit bandwidth barrier for real-time oscilloscopes and probing measurement systems. The Agilent Infiniium DSO80000 series oscilloscopes and the Agilent InfiniiMax II series probing measurement systems include 10 GHz, 12 GHz and 13 GHz versions. The performance level of these new offerings is vital to engineers designing high-speed serial buses, RF and wireless products, and other ultrahigh-speed devices.

Today's industry serial bus standards such as Fibre Channel, fully buffered DIMM (FBD), serial ATA (SATA), serial attached SCSI (SAS) and PCI Express have performance points that will reach into the 4 Gbps to 8 Gbps range next year. Proprietary high-speed serial buses can have clock rates in the 4 Gbps to 8 Gbps range as well as edge speeds with rise-times faster than 50 ps (20% to 80%). High-performance oscilloscopes, such as Agilent's new 10 GHz, 12 GHz and 13 GHz, 40 Gsample/s scope and respective probing system, are required to capture the frequency harmonics and make accurate and repeatable measurements on such high-speed signals.

“High-speed signal technologies are advancing at a rapid pace, which places pressure on designers to maintain the responsiveness, reliability and functionality of their designs,” said Galen Wampler, industry analyst at Prime Data. “As engineers strive to deliver the desired functionality at the required time-to-market, Agilent's new family of 10 GHz, 12 GHz and 13 GHz oscilloscopes and associated probing systems provides full bandwidth measurements to the probe tip while maintaining excellent jitter and noise levels. These products will contribute significantly in validating high-speed designs with accuracy and repeatability.”

Previously, designers were limited by oscilloscopes with a maximum real-time analog bandwidth of 8 GHz. The 13 GHz real-time bandwidth of the DSO81304A offers more than a 50% performance improvement vs. previous products. This translates into higher signal fidelity, accurate and repeatable measurements and improved test margins for high-speed electronics designers. High-speed signal components previously hidden to engineers can now easily be seen by this benchmark-setting test tool.

The analyzer features a variety of software packages to match the oscilloscope to specific measurement needs, including second-generation jitter analysis, serial data analysis with 8b/10b decoding, and a growing list of compliance test packages for standards such as PCI Express, Ethernet, DVI, HDMI, Fibre Channel, FBD and SATA. These software packages facilitate rapid problem identification and resolution for designers with specific test requirements.
