Figure 18: HBR2 crosstalk Setup for Trigger/Reference Clock Output

e. In the J-BERT N4903B go to PG Setup > Clock/Jitter Output menu.

i. Set the Trigger Output to the following based on the data rate being testing:

Figure 19: Controlling Crosstalk Amplitude on the J-BERT N4903B

For RBR

For HBR

For HBR2

Set crosstalk amplitude to

414mV

diff

Set cross talk amplitude to

1.35V

diff

Set the Clock/Trigger output

amplitude to 0V during this

step. Crosstalk amplitude will

be applied in 9.4.2.

3. If the Sink DUT supports FAUX, ensure that the DUT is transmitting FAUX traffic to emulate

crosstalk during calibration.
