How scopes deliver 20-GHz bandwidths and up

摘要

The year 2009 saw the rise of third-generation serial busses such as USB and SATA, and 2010 will see PCIe gen3 with a data rate of 8 Gbits/s and fourth generation SAS serial bus at 12 Gbits/s. In addition to increasing data rates for serial busses, the idea of directly digitizing signals above the X-Band (25 GHz) has become more common in applications such as satellites. Optical applications operating at 100 Gbits/s and greater are becoming increasingly more popular.
