The eye diagram should look like this after some seconds:
Check the Output of the Pattern Generator with a Scope
If the N4916B does not produce a signal, check the Data Out of the Serial BERT.
Connect the Data Output of the pattern generator to an oscilloscope.
N O T E
As long as the N4916B is in "connected" state (after pressing the Enable button),
the pattern generator's output is programmed to a fixed level. The amplitude is set
to 1.2 V, the offset to 0. This yields a signal of ±0.6 V.
