Stop on and Display Trace Errors
The eye-diagram analyzer has the ability to stop data acquisition when a mask
violation occurs. The number of traces or errors that stop this data acquisition
can be specified. In addition, if you are in eyeline mode, you can separately
display the traces that have caused an error.

Setup, BIT INTVL and enter 1, DELAY and enter –3
The mask will be offset to the right side of the display.

the error or trace limit is reached. Turn the number of traces function off by
