Agilent-Keysight DSO81204A en Lake Mary, Florida, USA

This oscilloscope is required to meet the performance needs of engineers designing state of the art high speed serial communication links and other ultra high speed electronic systems.
Modern industry bus standards such as Fibre Channel, Fully Buffered DIMM, Serial ATA, Serial Attached SCSI, and PCI-Express have performance points in the 4 to 8.5Gb/s range.
Proprietary high speed serial buses can also have clock rates in the 4 to 8.5Gb/s range as well as edge speeds with rise times faster than 50ps. 
These Oscilloscopes are required to capture the frequency harmonics of such high speed signals and make accurate and repeatable measurements on them.
