Depending on if an error detector available or not, we have 2 cases:
Case -1 (Calibration using an Error Detector)
– Connect Data Out of N4916B to Data In of Error Detector.
– Terminate Data Out of N4916B and Data In of Error Detector with 50 Ohm
termination resistor.
– Connect Clock Out of Pattern Generator with Clock In of Error Detector.
– Terminate Clock Out of Pattern Generator with 50 Ohm termination resistor
– For each of the 6 timing settings do a BER measurement using the following
accumulation setting
