The oscilloscope should show the following picture:
If you see only a straight line, ensure that the pattern generator is not
disabled and that it is set up to generate a pattern (e.g. PRBS).
Check the Output of the Pattern Generator with the Error Detector
If you have connected the N4916A to a Serial BERT you can of course
check the output of the pattern generator by means of the error detector.
1
Set up the pattern generator as described above: Set the Data Offset
to 0 V and the Amplitude to 1 V.
2
Set up the error detector as described above.
3
Connect the Data Output of the Serial BERT to the Data Input of the
error detector.
4
Ensure that the error detector follows the generated pattern.
