Mask testing
When used with the Keysight Infiniium
oscilloscopes, masks are provided for the
following standards:
–– PCI Express (2.5 Gb/s)
–– Fibre Channel Electrical (1.0625, 2.125
and 4.25 Gb/s)
–– Serial ATA
–– Serial Attached SCSI (SAS)
–– XAUI
–– FlexRay
When performing a mask test, the
High-Speed SDA software indicates the
number of waveforms (acquisitions) and
unit intervals tested, and the number
waveforms and unit intervals that failed.
This information helps determine your level
of confidence in meeting a given target bit
error ratio.

screen helps you determine the level of confidence in meeting your desired bit error rate.
