N4917B User Interface
The N4917B optical receiver stress test solution controls all of the instruments via USB, LAN or
GPIB connections.
The main screen of the N4917B software, the Stressed Eye tab, provides setting of the
paramaters required for the calibration of the stressed eye, runs the stressed eye calibration
and displays the results for the calibrated stressed eye components.
The two remaining tabs — Jitter Conformance and Jitter Performance are used when testing
the device for compliance or margin testing.
Figure 9. shows the stressed eye screen for 100GBASE-LR4 to setup the desired calibration parameters: extintion ratio,
vertical eye closure penalty, J2 and J9 jitter. In addition, various other parameters can be modified for individual setups.
