FER Results Window
This window displays the actual (FER) or cumulative (AccumFER) FER results:
• The FER is the current FER, calculated upon a period of 200ms.
• The AccumFER shows either the accumulated FER 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.
