Figure 20. Configuring the type of receiver test calibration to perform.

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.

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
