Receiver Stressed Eye Calibration (Continued)
The N5393D utilizes the PCI SIG’s
own Seasim simulation software to
determine the target signal impairments
and communicates those parameters
to the instruments configured as part
of the receiver test setup. The Keysight
DSA90000 series oscilloscope is used to
capture traces from the JBERT system
setup, and that information is used by
Seasim to set the calibration values of the
bit error ratio tester setup.

The N5393D option 004 is provided
to help automate the most rigorous
step in receive testing, the calibration
step. Once the equipment is calibrated,
the actual receiver stress test can be
performed manually or by using additional
automation tools provided by Keysight
and its partners. The N5393C-4FP
covers automates only the calibration
step. You can also reference the Keysight

Figure 21. In the HTML test report the N5393D generates the appropriate graphical summary for
each calibration parameter it configures. This gives you a traceable reference for how the tool
setup and the calibration can save time when de-bugging the RX test setup.
