DescriptionThe N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE LR4, ER4, SR4 and CLR4, CWDM4 and 4WDM specifications. In order to do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source are required to operate together to achieve a compliant, repeatable optical stressed eye. This stressed eye is then fed to the receiver under test, where bit error ratio is measured under the stress conditions as defined in the standard.Automation of the time consuming calibration of the optical stressed eye results in time savings of more than a factor of 10, compared to the manual setup.To control the whole set up, a turn-key software with test-automation is used, which limits the time consuming development of individual test software development.Stressed eye calibration screen generated with the Keysight N4917B optical receiver stress test solution softwareKeysight RF and Digital Learning Center - A commitment to learning with industry experts''
