8B/10B Comparison Results Window
This window displays the actual or cumulative results of the following
measurements:
• Symbol Error Ratio (SER). See
• Frame Error Ratio (FER). See

• Filler Symbol Ratio (FSR). See

SER Results Window
This window displays the actual (SER) or cumulative (AccumSER) SER results:
• The SER is the current SER, calculated upon a period of 200ms.
• The AccumSER shows either the accumulated SER of the current
accumulation, or - if no accumulation is running - the results of the most recent
accumulation.
This enables you to monitor real-time SER behavior as you do things such as to
manually adjust the sampling point, to add errors, or to make adjustments to your
device.
